Outstanding Experience with McCullough AC Company – Integrity, Professionalism, and Exceptional Service

I cannot recommend McCullough AC Company highly enough. From the very first interaction through the completion of my AC installation, the experience with everyone involved was absolutely outstanding. The level of professionalism, communication, and genuine integrity displayed throughout the entire process was simply unmatched.

Peter, the salesman, was exceptional. He was knowledgeable, straightforward, and genuinely interested in making sure I received the right solution. His honesty and integrity immediately established a level of trust that made the entire process comfortable and reassuring.

The installer was equally impressive, demonstrating excellent workmanship, professionalism, and attention to detail. The installation was handled with care, and the quality of the work reflected a real commitment to doing things right.

The service technician also deserves special recognition. His professionalism, knowledge, and willingness to ensure everything was operating properly reinforced the confidence I had in the company from the beginning.

What truly sets McCullough AC Company apart is that the exceptional experience wasn't limited to one individual or one stage of the job. Everyone involved delivered the same outstanding level of service, integrity, and professionalism from beginning to end.

In an industry where trust is everything, McCullough AC Company absolutely gets it right. They don't just sell and install equipment; they deliver an experience that makes you feel confident you chose the right company.

If you're looking for an AC company that stands behind its work and treats customers with honesty, respect, and integrity, look no further than McCullough AC Company.

Five stars without hesitation. An exceptional company with exceptional people.

Very professional and knowledgeable salesman. Low pressure sales, very affable. Showed up on time and with all necessary equipment.

Sam was the absolute best and got our AC working. Super nice and knowledgeable! Would high recommend him.

Matthew is professional and pleasant. Completed efficiently.
Identified an issue, Determined it was still under warranty, Ordered the part that day. Replaced it the following day
Excellent service Thank you

Thomas Castro did a great job servicing our AC. Very friendly and efficient. Would recommend!

Thomas arrived promptly, was courteous, and corrected the problem quickly. Excellent employee.
Robert Bluethman

From beginning to completion of the task my experience with McCullough Heating and Air Conditioning was positive. I especially applaud Raul,the tech. He is a man of integrity and competence.

James was very efficient and professional
We will be using him again for all our plumbing needs.

Sam was awesome. Very quick and timely and kept our air-conditioning running well for the rest of this season and prepare prepared for the heat we will use this winter! Thank you!

Desmond Lopez of McCullough Heating and air gave us outstanding service when our air conditioner was failing. He explained the issues clearly, and did not try to sell us anything. I really appreciate the expert knowledge and honesty. Thank you McCullough Heating and Air.

Excellent customer service and punctual technician Evan had a complete knowledge base of products. Made appropriate suggestions that were in my best interest!

We have the heater maintenance plan with McCullough and Kyle did a great job identifying things to fix to prolong the life of our heater! Appreciate the thorough inspection and quick work on our unit.

I have a service plan with McCullough HAC, and it is the best investment I have made for my HAC system. The AC stopped working, and with just one call, I got a next-day appointment. Matt, the technician, arrived on schedule, analyzed the issue, and fixed the unit; we were up and running in no time! Thanks, guys!

UPDATE: Second visit, same as above. Every technician is professionally trained (It shows!) Talking confidently about the subject gives me peace of mind.

New UPDATE—Summer 2025: A same-day appointment is settled! One of the benefits of having a service plan is the ability to rely on professional technicians to resolve our issues.
Call McCulloch HAC!

Fall 2025: Charles came for the fall-winter check of the HAC system. As always, a detailed and accurate check of the system is conducted, anticipating potential issues that, if not addressed, may result in significant expenses. Highly recommended!

New Update; Fall 2026: Very responsive in an emergency with my AC unit. Having their Premium program helps with these types of unplanned disruptions. Blake was very insightful in explaining and fixing the issue that caused the call, especially for someone with minimal or no skills in the topic. Highly recommended company all around. They keep earning my “5 stars” ranking!

Kyle was very helpful and informative. He was prompt to arrive, quick to do his inspection, and very courteous.

McCullough was referred to me by a friend as I was explaining how disappointed I was with 3 of the large local companies we had tried over 10+ years. I called them and the service appointment was scheduled within a few days.
I knew McCullough was different as the maintenance technician that came out asked me a lot of questions about the performance of our system. He then investigated the condenser unit and the air handling system while I tagged along. He showed me a few things that the other companies did not address. Long story short, I asked him to send out McCullough’s engineer to evaluate our current system and give us a quote for a new heat pump. Wow, that was a learning experience. Jensen walked the attic measuring duct sizes, air flow, and who knows what else. I told him about one room that was always hot and he said the duct was the wrong size and they would fix it. He was at our house over 3 hours. Mind you, at this point, we had paid nothing. We had the choice to replace the blower and a few other items, or replace the entire heat pump. After reviewing the costs, it made sense to replace the whole system as it was at its end-of-life expectancy. McCullough gave us 4 quotes, ranging from the ultimate to the frugal. Once we selected the option, they were out 2 days later installing the new system and taking away the old one. I must say I was very impressed with their respect for keeping their footprint as clean as possible. There were 2 technicians and then Jensen joined later. At one point, there were 4 people roaming around the attic! As we had them address a condenser line as well (one of the large companies installed it incorrectly when the house was built), their plumber made some recommendations that were completed.
Once all was done, we were extremely pleased with all the work, friendliness, professionalism, and expertise of all involved in the project. Their prices were comparable to the big 3 and they work with you on rebates and even financing if you need it. We highly recommend McCullough to be your HVAC maintenance team or provider for a new system. I now owe my friend a great dinner for the recommendation! McCullough will be our maintenance service team from now on

Our property management uses McCullough for all their HVAC repair and maintenance needs, and they are always communicative and friendly.

I needed to reroute some ducting in my attic, and it was quick and painless.

Our heating system was serviced by McCulloch technician Christen, who did an excellent job.
Thank you.

Sam was not only highly professional and knowledgeable but also incredibly kind and personable.

5/5 - I greatly appreciated his approachable and compassionate attitude as well as his expertise while he worked through fixing both our indoor and outdoor units.

(Also, congrats to him and his fiance!)

Courteous, timely and efficient.

Just had Mccullough heating and air come over do a cooling inspection on my HVAC system that I bought from them. Super easy, fast and thorough with pictures and all of their readings. Worked with a technical named Miko that was very courteous and easy to work with. Highly recommend!

11/9/26 - Brief update. Had another technician come in to do my winter inspection and his name was Marco. Marco was fast and easy to work with and did some minor fixes to ensure my heating system was all ready for the winter. Thanks again!

I am on their yearly heating and cooling checkup plan. So they come out twice a year, at least. The technician Marco was thorough, explained things well, replaced a part that was under warranty (and I didn’t have to do any paperwork) and did another needed repair. And put new weatherstripping in the attic access hole. And cleaned up after himself. So I am satisfied. I also liked the technician whose name I can’t remember who came to help with an emergency situation earlier this summer. He was very thorough and explained things well. And, time showed that his assessment of the situation was correct.

The HVAC technician Shawn May was very efficient and helpful. He clearly knew what he was doing, and he was very polite and friendly.

Updated review for new HVAC installation. The team did a great job installing new ductwork and system. They were able get it done quickly and with care. Big thanks to crew member Ayden , he took the time to install my atypical vent covers and did it with care , it was very appreciated as I see them everyday.

I had a damaged and inoperable HVAC system caused by an incompetent contractor, and I needed help fast. Eric S. from McCullough was able to quickly come out and repair the damage. The quality of the work was top-notch, totally professional-grade workmanship. On top of that, he was super knowledgeable and was happy to educate me on what he was doing and why. Thanks, Eric!

Today I had an inspection conducted at my house of my water heater, water lines, water quality and pressure, toilets and tubes. I was a little afraid because of today’s pricing but am so grateful that it was done due to the findings and wonderful advise I received. James Farr is a licensed plumber and is good at what he does. I highly recommend him. I love McCullough and am grateful they have him.

Mr. M. Santo was very professional and polite, while demonstrating exceptional technical knowledge.
He thoroughly serviced our HVAC system.

I have been using McCullogh since the installation of our HVAC system in early 2020. Have yet to have a bad experience- always timely, professional, and knowledgeable. Grateful! PS: Eric is a great technician.

Thanks to Bryan for a thorough and professional checkup of our HVAC system.

Matthew came out for our semi-annual check. Heaters both working well. Gave me some maintenance advice. Not pushy - easy to understand. Gave me a full walkthrough of the system.

Kevin was excellent. He was prompt, friendly, and knowledgeable.

Jaiden was great! He took extra time to answer many of my questions and told me about the new/improved filter that was just recently released for our unit. McCulloughs is awesome!

Blake is an outstanding tech. He came to perform annual checkup.Very personable and technically savvy. Answered all our questions and gave good suggestions for system efficiency. He called and gave us a heads up when he was on his way with the ETA. He worked quickly and efficiently with no disruption to us at all. Mccullough doing good with techs like him.👍

Thomas fixed my AC!

Shawn, the service technician, was super professional, expedient and friendly!

Showed up on time for my regular 6 month HVAC health check. I explained to the technician that the smart thermostat was complaining about high humidity, which he quickly diagnosed and fixed (by siliconing the hole in wall behind the thermostat). He then performed a quick and thorough check of the HVAC system. Kudos to Raul, who was a very friendly technician that answered my questions clearly.

Will K. Came to do a plumbing inspection for us. Very thorough and respectful of our property.

Craig at McCullough is awesome! He discovered the problem and resolved it immediately. Also very personable and pleasant personality. He was very knowledgeable and answered all our questions.

Mat helped me evaluate an issue with my washing water valves. I really appreciate Mat's work here, though the issue was minor. He showed me reasons of stuck valves and how they may be solved. He did some extra evaluation as part of the visit to help me check everything was on shape. I recommend the plumbing service of McCullough.

Thomas was the best! Quick, thorough, and upfront about everything. Really happy to have his help, he definitely cares about doing a good job. Will definitely be trusting with this crew again

Thomas was our service tech today. This visit like all the others was exceptional. Friendly, professional and able to answer my questions completely. Highly recommend the team from McCullough.

I was experiencing so issues with my thermostat so I gave McCullough Heating and Air Conditioning a call. My appointment was scheduled for November 2 and Kyle gave me a call advising he would arrive in approximately 30 minutes. Upon arrival Kyle took time to listen to my concerns with the thermostat. He made a few adjustments and to ensure that the thermostat was switching between hot/ cold and and all my questions regarding my thermostat. Thanks Kyle.

Tom c - is an awesome technician, who was very knowledgeable and helpful with our leaking. I will definitely use him and McCullough again.

Thomas was our HVAC tech. He was very kind and efficient. He let us know about their monthly membership which allows us to have our system checked twice a year including free diagnostics if something were to go wrong. Ultimately the yearly cost breaks even but with some benefits. It’ll ensure our system runs smoothly for years to come, so we plan to sign up for that. We are first time homeowners and I appreciated his advice and help. Support your local family owned businesses!

Matthew has been the best HVAC technician we’ve worked with! He was friendly, professional and extremely knowledgeable. We especially appreciated the time he took to thoroughly explain the issues and walk us through his recommendations. It’s refreshing to work with someone who genuinely cares about providing excellent service. We would absolutely love to have Matthew as our go-to McCullough technician moving forward!

Great communication and thorough follow-up

Brandon was timely and courteous and efficient. He explained clearly the issue and got it working.

Brandon was a fabulous tech! He was so thorough and explained all that he did to check our system. He was truly the best tech I have had.

Sam was very helpful and professional

Great service as usual! Very polite and knowledgeable!!! Yay!

Marco Lopez was efficient and thorough. He offered a maintenance contract that sounds very reasonable.

Craig did an awesome job. 👍👍👍👍

Sam came out and quickly identified the problem, had the correct part drop shipped to the house and came back the next day to properly install and confirm the system works as advertised!

Very friendly technician came by and diagnosed a problem with our AC unit in the attic. He made several changes that should stop the water drip under the unit. Great explanation and it sounds like he resolved the problem.

I knew I needed to replace my aging HVAC system, but I was concerned about the process and the cost. I reached out to McCullough for a quote. Kelvin came by to evaluate what I would need and he provided quotes for multiple systems, as well as some guidance on how I could obtain financing and qualify for rebates through Austin Energy. I knew it was going to be a question of when I replaced the system, not if, but I had waited because I was worried about the cost. I kind of wish I had done this years ago because it was easier than I had expected.

Though the job was estimated to be 2-3 days, the install and weatherization crew were able to complete everything within a day and a half. They installed the new outdoor unit, the air handler, a new thermostat, and most of the ductwork within the first day. They returned the next morning and finished connecting all the remaining ductwork. The new system has worked like a charm ever since. It runs less frequently and for shorter times than my old unit did, but it keeps my home more comfortable because the new ducts move a greater volume of air.

I went with McCullough in part because they had positive reviews, and in part because Kelvin was great to work with and made a complicated process relatively easy. I’m set for the time being, but when I need to replace this system, I’ll be going with them again.

I just had a free plumbing inspection at our house as part of being a Comfort Club member with McCullough. James Farr was the plumber who did the inspection and his visit was very informative and pleasant, as well. He was very thorough and assessed our plumbing in ways I wouldn't have thought of, checking the usual areas but also water quality and hardness. I recommend this service to anyone, especially if you live in an older home, like we do.

My technician Craig did an excellent job, was knowledgeable, friendly, resourceful, and very hard working. I’d definitely choose him again in the future.

Shawn was our technician. He identified an issue that needed to be addressed! Very professional.

Henry came to the rescue to fix a problem created during the original installation six weeks ago of a new 3 ton system. He came Thursday afternoon to resolve it so I wouldn’t have to go the weekend without cool air in my kitchen and family room.

Raul diagnosed problem that radiant missed . Easy fix! Very happy

Brandon was amazing! So polite! So informative. He is absolutely the best!

Sam came late, diagnosed the problem

Tech was friendly and professional. Checked out our heating system answered my questions. He also changed the filter and reset the filter reminder on thermostat.

McCullough Heating, Air Conditioning & Plumbing is my go-to choice - and not just because we share a name! (No relation, btw.)

Today one of the service personnel, Craig, came to make sure all systems were functioning. He was professional and went above and beyond to optimize both HVAC and heater were in top shape. I appreciate the thoroughness and I can rest assured I never have to worry. Highly recommend.

Great customer service and impressive knowledge of system

Santos pursued the problem which most people would have given up. Good work Santos.

Took advantage of complimentary check of gas leaks and carbon monoxide exposure during my regular maintenance. Service tech noted that the attic light wasn't working and SURPRISE a gas leak in the attic at the service valve that a plumber will need to repair. Thank you McCullough. And a big shout out to Makayla, the best service tech I know!

Got a full system replacement with add-ons and some duct work. Evan was a great resource for figuring out the best way to handle our house, and Brian's install crew got it all done and detailed right on time. Everything was professional, quick, and clean from start to finish. Easily recommended.

Raul very helpful
Company very flexible with my time constraints

Absolutely amazing experience. James gave the most extensive overview of my plumbing. He thoroughly discussed recommendations and sent a full report. He was not flustered or distracted by my dogs who showed great affection. James is a real people person taking in account my age and lifestyle when assessing my plumbing needs. McCullough made a great decision to add plumbing to their services and found a real gem by hiring James.

Matt provided great service! He was knowledgeable, courteous, and thorough. He helped me find the best deal and the best solution. I would recommend him for any plumbing needs.

Shawn came to do a maintenance checked today. He was professional and personable. I have been very pleased with McCullough after updating my HVAC.

McCullough sent Sam our way to track down a problem causing our kwh usage to climb recently compared to same billing periods in past years. He was very persistent with his diagnostic procedures but got to the end of his day and will need to return tomorrow. The AC is cooling just fine so no inconvenience there. I am pleased that he is determined to find the issue and resolve it. It shows that he cares about his job and his customers. O

Our garbage disposal wasn’t working. I was so happy to learn that McCullough now offers plumbing services, and that free visits are included in my Comfort club membership! Will K came out and took care of everything and got our disposal working in no time. He gave me a courtesy call ahead of time, and was friendly and efficient. Think you, Will for helping us out today.

Kyle was fantastic! On time, fast, and high quality service.

Highly recommend McCullough Heating and Air. On one occasion, our AC went out shortly before weekend guests were to arrive. Kyle and his team showed up after hours and quickly fixed the problem. We are incredibly grateful for their responsiveness and willingness to go the extra mile. Thank you Kyle and McCullough team - true professionals.

Marco Lopez provided our Heater system & maintenance. Polite, professional, & very efficient. Answered our questions & provided very helpful recommendations.

Will Kamenitsa was my McCullough plumbing technician. He was friendly, polite and professional, and kept me updated at all times as to what he was doing.
Will also made suggestions on updating my dated faucets to keep my plumbing in good repair. I plan to follow his recommendations.
5 stars for Will!

Shawn and Joel were professional and diligent in resolving the AC issue.

Craig was very helpful today with checking the furnace and the A/C system and make sure everything was in order. Definitely recommend their services.

Marco went above and beyond to provide excellent service and make sure I have confidence in my system for the coming season. Always appreciate his expertise and easy to work with demeanor.

Sam did a great job.

Mathew was very polite & thorough. Explained recommended service needed clearly.

Great service! Sam was very helpful

I worked with McCullough for a pre season tune up in April and again in October for a drain issue. Overall I am happy with their responsiveness and service. Sam returned to my home twice after the first visit to ensure the job was handled correctly after things came up.

Professional, informative and courteous.

Excellent, knowledgeable and professional’

Raul Alcaraz was very professional, kind, and courteous throughout the entire process. Raul took the time to explain everything clearly, worked efficiently, and made sure everything was taken care of properly. His friendly attitude and excellent customer service. I highly recommend Raul to anyone!

Kyle Sterling was a top notch technician and guided me through everything during our appointment today and helped take care of all of the issues with my AC! Very grateful for his patience and fast thorough service!

Marco did in great job doing maintenance on our units October 26.

Blake was great. Checked the AC units out and changed the filters. Even put in the vinegar down the drains for me.

Thomas Castro was a fantastic tech to work with. He went beyond the extra mile to not only get my AC back up and running yet additional, much-needed preventative maintenance work as well.

9/14/2026 McCullough’s technician Sam repaired our AC system with expert problem solving and efficiency; clogged water line caused system to shut down. Having McCullough’s comfort contract we were not charged for the visit and analysis. We did pay for labor to cut and flush the waterline and install an access coupling. Sam proposed two solutions, explaining both clearly; showing photos of each way to have future access to flush the water line if needed. His professionalism , expertise, efficiency and clear explanations were much appreciated. This repair reinforced the value of keeping McCullough’s comfort contract (2x/year inspections) for Heat and AC maintenance visits including emergency servicing; much needed in 90°+ heat!

10/8/2023 Kyle replaced broken thermostat and inspected heating system. We have McCullough’s yearly maintenance agreement. Kyle ‘s knowledge of HVAC system is characteristic of McCullough’s standard of high technical expertise, of their technicians, on which we depend for our HVAC system. Between maintenance agreement and 2018 new system warranty, the few incidents of AC loss have been covered. The maintenance agreement is well worth the subscription price.

July and August 2023; James Sanchez & The McCullough Team provided reliable service for our 2018 new system described below. In June, 2023, during the annual AC maintenance visit, James showed us how to water the outdoor AC unit to remove dirt generated by water and sewer line construction which would eventually have become clogged and shut down. And, this July, James fixed our AC system when an electrical connection shut it down. Both visits were included in our annual maintenance contract that covers inspections and emergency visits. We will continue to maintain this very worthwhile McCullough contract.

McCullough installed our state of the art AC/heating unit in 2018. This unit has received yearly maintenance, except for 2020, due to COVID. This computerized system, provides readouts on the thermostat; alerts for replacing filters, routine maintenance due, and any system failure. It shuts down when any inconsistency in performance is detected preventing damage to major parts. There have been two instances of system failure, both under warranty. In each instance, McCullough answered our emergency call to restore AC in a timely manner. Yesterday, I was both relieved and impressed to receive text updates on their technician's arrival time. Herman quickly discovered the problem and restored the AC to running within an hour. McCullough has been consistently professional in scheduling, communication, and charges for maintenance. I am glad we used the same company to instal and maintain our AC/heating system. I highly recommend McCullough for installation and maintenance of a new AC system.

Brandon did a great job. Explained everything he did in detail and answered all my questions.

Great service

Thomas did an excellent job on our HVAC repair. He arrived promptly, quickly diagnosed the issue, and had the replacement part on his truck. He also did a thorough review of the system to make sure there were no other problems. Thomas was knowledgeable and made several recommendations for how we can better maintain our system going forward. Thank you!

Guillermo is a great communicator, and he was friendly and courteous the whole way through.

Technician provided appropriate notification of arrival time; was courteous and professional. Informed me of work performed and issues noted.

Really appreciate McCullough coming through for us today! Our AC stopped working after some utility work in our yard caused a clogged drain line. They were able to move up our scheduled maintenance appointment to help us out. Sam came out, was very polite & wore shoe covers, got the line cleared, and shared some helpful maintenance tips. We're grateful they were able to fit us in on short notice and get our AC running again. Thank you!

Will was great. No nonsense good conversation and quality information. Thank you!

Matthew was friendly and knowledgeable. He took the time to answer all my questions and explain what was going on with our a/c.

You scheduled a technician to come to my house the morning after my call. Robert, your technician was GREAT and he quickly found the issue as to why my recently Carrier heat pump was not working. The condensation line had clogged and the safety shutoff was activated. Robert explained the situation and put an antibacterial solution in the condensation drain line and used compressed air and vacuum to clear the clog. It was all covered by warranty and he showed me where to pour about a half gallon of regular 5% vinegar when I changed my air filter to keep the condensation drain line clear. He was soft spoken and calm and knew what he was doing. Thanks so much!

Guillermo did a great job with our furnace inspection. I appreciate his call twenty minutes before arrival to make sure it was ok to head over. He was very polite and respectful of our home and time. After completing the inspection and changing our filter, he explained the inspection, and offered a call with the service manager for an updated quote on a new system. We had been interested in getting one, but didn’t have time for an in-person appointment. I really like that he gave us tips on changing our filter and AC & furnace maintenance without being pushy.

I highly recommend McCullough Heating & Air, they always take great care of us!

Sam did a great job. Thank you!

Hands-down the easiest, most professional and efficient HVAC company around. They are very responsive, knowledgeable and easy to work with. We’ve had many HVAC companies out over the years (old system) and this was hands down the best experience. Eduardo and Miguel were incredibly nice to work with during the install- they were knowledgeable, efficient and incredibly quiet while we had two adults working from home during the install. Ricky was our sales rep and he was super responsive and helpful from initial quote to final signing. Can’t say enough good things about this entire team and experience.

Had a great meeting with Clayton. No hard sell at all. He answered all of our questions and explained our options very clearly. It was a pleasure meeting him and exploring the options in detail.

Sam was thorough and very communicative. We much appreciate his work and professionalism.

Guillermo is very thorough and professional. He is very knowledgeable with clear explanations easy for us non-HVAC people to understand! We would definitely welcome him back!!!

Plumbing inspection and resulting minor repair for Comfort Care customer. Timely and responsive. Way better thsn the HVAC side of McCollough, should strive to meet the standard of service and scheduling adherence with its Comfort Care customers.

Very happy with McCullough’s customer service. Sam our technician was courteous and responsive. Got us back up and running quickly. Definitely recommend them for AC and heating services.

Technician Matthew Santos did a great job. He found the problem quickly, went to pick up the part that needed to be replaced, and got my A/C up and working quickly. I was very satisfied with his professionalism and friendly demeanor.

Evan and the McCullough team did a fantastic job installing a new AC in my old, 1949 house. I have been very let down in the past by AC companies in town who have promised to fix the issues
at exorbitant costs, to no avail. Evan and the team listened to me, took notes, found solutions, and guarantee their work.

Now, I can comfortably exist in every room of my house, which has not been the case for a very long time. Thanks, Evan and team!

I have been using McCullough Heating & Air Conditioning for over 6 years. I have a maintenance service with this company. Alonzo Olivias, the technician that performed the service was knowledgeable, professional and friendly. Their customer service is excellent. I highly recommend this company.

Lore Harris

** Nine years later and I’m doing another review,
Same wonderful company, but I really miss the ladies answering the phones and giving you great customer service.
Matej Bzdil came out to my home and did some maintenance checking. I was a little nervous because it was about three years that I hadn’t had them out. Matej Bzdil was very thorough and professional. He also was patient and explained everything and was not pushy. He gave great customer service I was very confident with his work. He also suggested the maintenance program. I have been on it before but time got away from me. So I’m back on the maintenance program.
Thank you Matej Bzdil.
Lore H.

We have used this company two other times for complete AC and heater installs at other houses. They are professional and do a good job. We have felt their prices were competitive and fair. Their installers take care to keep the area clean with drop cloths and shoe covers. They wear masks and use good Covid precautions. We will continue to use their service.

Update: McCullough tech, Mitchell Reaves, did our annual inspection of our heating/cooling system this week, He was efficient and pleasant. He checked out our two systems and answered all of my questions. This annual inspection was part of our contract for maintenance that we pay monthly and is reasonably priced. We will continue to use this company.

Update: 4/26 Jayden with McCullough came out to troubleshoot an issue with my heating system. He was excellent. He took time to diagnose the issue, asked good questions, worked as long as he needed to fix the problem and then double checked both the AC and heating systems to make sure everything was working correctly. I was very impressed with him and hope I see him again the next time I need AC/heating service.

Update: i recently used McCullough plumbing service to evaluate my plumbing dudtems and to fix a couple of problems. The plumber, Will K, was thorough and completed the work efficiently. Plumbers are expensive, but I felt they charged normsl plumbing fees.

Sam was incredible and came out to help me in a pinch! Not nickel and diming me and really cared to resolve my problem.

Sam did a great job

Sam helped me move some items blocking access to the attic before he checked the unit in the attic and the part outdoors. He quickly found two problems, one with the filter and one in the compressor. He set up an appointment to get my unit inspected and install a new filter. I signed up for monthly service, and my house is cool again! Thank you, Sam!!! You made my day!!!

Great work, timely done, and McCullough should be proud to have such a nice and dependable tech as Shawn. Well done!

Sam was awesome. Thorough and helpful.

Thomas was so knowledgeable and helpful! He solved our problem and explained everything to us clearly. We will definitely request him in the future.

Thomas C. came out to fix our AC unit and did a great job. He explained the issue clearly, and resolved it quickly. Efficient, professional service—would definitely use them again.

I usually use McCullough for HVAC maintenance, but this time I needed plumbing help with a clogged bathroom sink and low water pressure in my master shower. James was amazing and fixed both issues! As a first-time homeowner, I really appreciated his patience and how thoroughly he explained things, including how to protect my tankless water heater during Austin’s winter freezes. Excellent service, very helpful, and professional. I’ll definitely use them again! Highly recommend—ask for James!

Sam Marquez was my technician today, and I couldn’t be more pleased with the service he provided. He was extremely professional, informative, and went above and beyond to ensure my HVAC unit was functioning properly again. I truly appreciate his dedication and attention to detail. Excellent service from start to finish!

Sam was excellent and fixed our issue — on the weekend! He was very thorough and addressed things someone prior had missed. Could not have better things to say about him. Thank you Sam!

Sam was incredible and came out to help me in a pinch! Not nickel and diming me and really cared to resolve my problem.

When I had several technical questions about proposed improvements to my HVAC system Clayton Crain was the right person to speak with. He thoroughly and clearly answered my questions and set an appointment to come look at my installation to ensure that the details of the proposal would be appropriate for my situation. This is an example of the great service offered by McCullough: technical expertise with a customer centered approach!

They've been great for years. HVAC and plumbing.

Thomas was awesome and did a great job on the HVAC tune-up. I will request him next time too.

Ryan was great. Knowledgeable, professional, timely and friendly. Got the service I requested with no other add ons. He offered a great optional estimate that was very helpful. Will definitely be working with McCullough again.

Everyone I’ve worked with has been friendly, professional and competent. They say what they’ll do and do what they say…and if there’s a problem will work to resolution.

The technician was courteous and professional and answered all my questions. My only gripe is with the scheduling of the company. I wish they could better narrow down arrival time to either morning or afternoon. Miko did a great job of not only doing the maintenance and upgrade (added some refrigerant and a quick start kit) but explaining everything he was going to do.

McCullough’s technicians are great. Marco was very polite and did a good job. Thanks

Thomas was very informative, knowledgeable, and patient. He helped guide us through an issue he got and was very honest and straightforward. We will be coming back again!

The technician was courteous, went straight to work, explained everything he did and closed out his work. He demonstrated a good work ethic and it was noticed and appreciated. Hard to get that these days.

Thomas Ischy was a fantastic HVAC technician. During our emergency visit, they solved our problem (drain line clog) and did multiple things to prevent clogs in the future. They showed me a few things I can do before calling. I highly recommend becoming a comfort club member. It's worth it, especially for the great service.

Blake was great, arrived early and finished maintenance quickly. Communication with the company was easy and reminders kept us in the loop. Blake kept us updated throughout the maintenance process and provided his recommendations without overselling. Would recommend McCullough.

Kyle came to my home and did an amazing job repairing my ac system

Courteous and efficient!

Nice tune up from Marco Lopez today. Capacitor was starting to go so he replaced it under warranty repair

Sam preformed the winter check up on the unit and he very professional on the he did. Explain any question I had. Overall the service was excellent and very professional. I will have no problem recommending him to anyone.

The technician, Craig Plank, did an excellent job in servicing our systems. He was thorough and informative. Thank you for the expertise and professionalism!!

Kyle was provided exceptional support! He was very knowledgeable during the diagnosis. Then gave me the step by step plan for today’s repair and also gave me info on next steps if the issue persists.
I felt that he was very thorough in his diagnosis and solution.
He made a few suggestions on how to up keep the unit and listened to all of my concerns and provided quality answers that were easy to understand.
He even took the time to chat with my husband on the phone to answer his questions.
A++ Kyle! We appreciate the great service!

McCullough heating and air has always given us top quality service with technicians that had amazing technical skills and great communication skills to explain the issues and process.

Makayla is a real pro in diagnosing. Friendly. Personable. Explained possible options. Seems to like her job. The whole experience lightened my heart. I'm now at ease. looking forward to hvac replacement.

Christian was very professional with his work. He provided and explained all faults found with our ac systems to my satisfaction. Thank you Christian and Team McCullough!

I had my heating inspection today that was part of my bi yearly maintenance contract and I had to make an adjustment on the timeline due to an appointment- I was able to do that easily the night before with the automated system since it was the weekend and the wonderful technician, Sam Marquez, showed up timely…. Was so kind, respectful, appreciative, complimentary. He explained the service & made a suggestion for the future. Sam was GREAT! Peace of mind having this service completed with the extreme Texas weather !

Bryan, did a great job servicing two of our units.

You guys always do a great job!!

Kyle was great! He was professional, informative and knew exactly what the problem was. Thanks for the efficiency, Kyle!

Shawn at McCullough bent over backwards and even made two trips to my place to get our system working. He’s outstanding, super professional and also very relatable- we had great conversations during his time here.

I’m 100% calling these guys again and asking ONLY FOR SHAWN!

We very much appreciate the excellent and timely service provided by tech Marco Lopez and the McCullough team this week when our 2 year old Carrier A/C system couldn’t get us below 82 F.
Marco quickly determined that there was coolant leak in the evaporator coils. He immediately ordered the replacement coil assembly which was delivered to us within 2.5 hours. Marco then returned and proceeded with the replacement operation and then (holding an umbrella in the rain) did the outdoor work to recharge the system with coolant before resealing the indoor unit and thoroughly verifying that it was operating correctly.

Thank you, Marco and team for an ideal response to our emergency!

Again, absolutely great service, did exactly what I requested. Always prompt. Kyle offered up his knowledge and did a great job, really appreciate it, thanks Paul

Technician Alvin Moore paid me a visit, and did a great job. 🙂 He’s also a nice person.

I’ve been a long-time McCullough customer and this spring I needed to replace my HVAC system. Evan Young, Sr. Project Manager did calculations at the house and provided several new system options. Evan also suggested adding another air return to increase the air flow for better system performance. And this feature was not a big cost —$100.
Evan was great to work with, quite knowledgeable about HVAC systems, and answered my questions.
The installers arrived on time and worked hard to get everything in place. I’m glad I added the extra return.
I am pleased with McCullough’s people, quality services, and emphasis on customer satisfaction.

Super helpful and honest. Great Service and available on short notice. Highly recommend!

Will was great! He was thorough, knowledgeable and answered all of my questions. Great inspection!

I'm normally a DIY type of guy, but when I couldn't figure out a few issues, Kyle S. with McCullough Heating and Air Conditioning was a great technician that helped me out. He was super polite, honest, and it was very clear that he knows what he's doing. I would 100% trust him to come back for any issues or routine maintenance checks.

McCollough takes good care of my system. Always communicative, prompt, and professional! Kyle always does a great job and is very personable.

Excellent experience. The plumber was knowledgeable and fixed the problem extremely quickly and the price was great. Will is a pro and I will definitely request him in future.

Kyle was excellent! A great technician and very professional.

James is an exceptional professional, and we are thoroughly pleased with our interaction, and his superb service, attention to details, and his incredible patience when educating his clients.

Craig with McCullough came out today to service our HVAC system, and he did an excellent job. He was thorough in his work and took the time to walk us through everything he did, which we really appreciated. It's clear he takes pride in doing the job right, not just fast. Great service from a knowledgeable, honest technician — highly recommend asking for Craig!

Excellent customer service and punctual technician Brian. Made appropriate suggestions that were in my best interest!

Josh is a well qualified Technician.
Thank you for the diagnostic service

James was very professional and thorough in his inspection. Explain things clearly. Felt very comfortable with him in my house.

Matej showed up same day to solve a plumbing issue that we had. He diagnosed the problem correctly, explained my options well, did great work to fix it, and helped us find a company to deal with the water damage. He really brought joy to an unpleasant situation.

We had an excellent experience with Raul and The McCullough Team! ⭐️⭐️⭐️⭐️⭐️

They came out to my son’s home after we had a very disappointing experience with another company sent through American Home Shield. My son pays faithfully for his home warranty, so we expected to have a knowledgeable and professional technician come out and properly address the issue with his air conditioner. Unfortunately, that did not happen with the previous company.

Thankfully, Raul came to the rescue! He was extremely knowledgeable, professional, thorough, and took the time to make sure the job was done correctly. What a difference it makes when you have someone who truly knows what they are doing!

We are extremely pleased with Raul and The McCullough Team. Thank you so much for providing such excellent service and giving us peace of mind. You guys are amazing, and we will definitely be calling you again and recommending you to others! 🙏🏽❤️

Great service call. Blake said the message I got was just information. He went over the operation of the thermostat and showed me how to look at how the unit was performing. Blake was a very nice, know, But you don’t know what how much is how much did them could be a But you don’t know what how much is how much did them could be $1000 or more?and informative service rep. Will definitely continue to use McCullough Heating & Air. And Blake is an asset to the company.

Thomas was great.

Thomas was courteous and thorough during the repair process. Great customer service.

I highly recommend using McCullough Heating & Air Conditioning. My AC went out on a 100 degree day in Austin, TX and needed it fixed ASAP! Thomas (the technician) showed up same day, part in truck, and fixed it right on the spot. Simple, quick and easy. Would definitely call again in the future.

Marco Lopez inspected and diagnosed my AC unit’s problem and determined that I was not getting any cool air circulation because of a dysfunctional fan motor. After locating a new part, he installed it the next day. In addition, he inspected and cleaned my compressor. He was very professional and courteous.

Matej arrived on time and was very thorough in evaluating our drain and resolving the issue. We would use him again for any plumbing needs.

Mikayla was the best tech, I've ever had. Hands down the best.
Guerrero Mata was fantastic . Explained everything he did. He even washed my ac. Please give him a bonus.

Thomas Ischy did a good job fixing condensation issue.

We had a clogged drain pipe and leaking duct vents. Thomas Ischy did a great job sealing.

The only issue we’ve had with McCullough - Don’t trust the online scheduling - twice we’ve tried to schedule that way and it just doesn’t seem to work. We schedule but they have no record of it. HOWEVER, when we call to schedule, they get us on the schedule quickly. Had another AC issue. Kyle came out on a Monday, diagnosed the problem, the part was ordered, part delivered to our home on Tuesday. Kyle came back out on Wednesday to install. Under warranty again!!! Yay!

Extremely pleased with Guillermo Mata and the McCullough team. Thank you!

Update: September 2026

I am so glad I'm a long time customer of McCullough Heat and Air. All the techs who have serviced our HVAC have been great but this time around Mike McTaggert went truly above and beyond. Our system had a backed up drain on a 106+ degree day. Mike came quickly and knew exactly what to do. Moreover, he showed us photos and video so we know exactly what happened and how he diagnosed and fixed it, all the while being really friendly and efficient. Because of folks like Mike, we will always be McCullough Heating and Air customers.

We came back in town and our AC was out. McCullough came the afternoon we called and diagnosed, quoted, and installed our new unit the next day and it was GREATLY appreciated not only because the temps were in the 100's, but i had out of town guests coming and was hosting a bridal shower. Each and every employee we dealt with was extremely hard working and very responsive. I would highly recommend them!!

Matthew S. was very thorough, patient, professional and knowledgeable. And a pleasant person to have in our home. My HVAC unit was recently installed by McCullough, so there was no charge.

Friendly, professional, honest assessment and AC repair service. Thank you.

I just had a free plumbing inspection at our house as part of being a Comfort Club member with McCullough. James Farr was the plumber who did the inspection and his visit was very informative and pleasant, as well. He was very thorough and assessed our plumbing in ways I wouldn't have thought of, checking the usual areas but also water quality and hardness. I recommend this service to anyone, especially if you live in an older home, like we do.

When my AC went out, McCullough was recommended to me.
I am glad they were.
From the man who came out to check it, Raul, the man who came to explain my options, Evan, to the two that came out and to install it, Miguel and co-worker (sadly I didn't catch his name), it was a quick and smooth experience.
I will be recommending McCullough to any and everyone with HVAC issues.

Jaiden was very helpful and thorough. Instead of just identifying the obvious issue he took the time to try to look into the cause, and was willing to work around my schedule for the follow up repairs.

James was very knowledgeable and his recommendations and repairs fixed our water pressure issues immediately. Quick service and fair pricing too. We definitely recommend James and McCullough

Thomas is fantastic as what he does and makes the process easy and is transparent about everything. 100% would love to have him back out if something goes wrong.

I came back from being out of town to a house that was 95 degrees inside. AC is kind of a black box to me, so you never really know what the issue is or what you’re about to be told it’s going to cost.

Mike came out, figured out what was going on, explained everything clearly, and gave me a couple different options without any pressure. That made a stressful situation a lot easier.

He got the AC back up and running, and I had a really good experience with McCullough. I’d definitely call them again.

Craig Plank our technician was excellent. We called for a second opinion after another HVAC company told us we had a refrigerant leak and strongly implied that we needed a new system. Craig took the time to inspect everything carefully, explain what he was checking, and give us a clear, honest assessment.

His conclusion was completely different from the first technician’s. He did not find evidence of a refrigerant leak and explained that the refrigerant itself was not the toxic emergency the first company had made it sound like. He was straightforward, patient with our questions, and did not pressure us into an expensive replacement.

It is frustrating to feel like the first company may have been more interested in selling us a new system than accurately diagnosing the issue, so we are very grateful that McCollough gave us a thorough and trustworthy second opinion. I would absolutely recommend them to anyone who wants an HVAC technician who is knowledgeable, honest, and not trying to upsell unnecessary work. In fact the second opinion was free and he would not take any money for it even when I offered.

Service technician knowledgeable, efficient and courteous. Problems were outlined, suggestions for repairs given, and written report received . I have been pleased with the straightforward approach both times I have had service done. I can easily recommend McCullough to anyone who needs air conditioning evaluations and repairs.

The technicians Jaiden Mendez were very thorough and knowledgeable. He was respectful and did a great job at assessing the AC unit. Highly recommend this local business to anyone that needs help with AC and heating.

Ryan done a superb job and helped me to understand the Eco system a little better.
Highly recommend their services.

I had the pleasure of working with g with one of your most senior technicians, Kyle, last week. It was an emergency call during a heat spike with the AC stopped. He came after 5, solved the problem, and detected other maintenance issues that were about to trigger other outages. He ultimately came twice to the house, fixed several minor and major issues, and explained how to prevent further issues in the future. I will always be indebted to Kyle for the quality of his work and his tenacity. Our units are hard to reach and he went so far beyond our expectations. Your company will rise or fall on people like Kyle. Thank you!

A service manager called me and said he would look into the problem and help resolve.

Frank

So pleased with our initial service call with Craig. We are new to the area and wanted a service contract for our new home’s HVAC system. Craig was right on time- pleasant and professional and answered all of our questions! He suggested a new part to increase efficiency and it was quickly installed!

Was really pleased with this company’s s service today. The Technician Matej was personable, proficient and honest. I am so happy to be a member/ subscriber and I really appreciate the way this company does business.

Very professional, outstanding customer service

9/14/2026 McCullough’s technician Sam repaired our AC system with expert problem solving and efficiency; clogged water line caused system to shut down. Having McCullough’s comfort contract we were not charged for the visit and analysis. We did pay for labor to cut and flush the waterline and install an access coupling. Sam proposed two solutions, explaining both clearly; showing photos of each way to have future access to flush the water line if needed. His professionalism , expertise, efficiency and clear explanations were much appreciated. This repair reinforced the value of keeping McCullough’s comfort contract (2x/year inspections) for Heat and AC maintenance visits including emergency servicing; much needed in 90°+ heat!

10/8/2023 Kyle replaced broken thermostat and inspected heating system. We have McCullough’s yearly maintenance agreement. Kyle ‘s knowledge of HVAC system is characteristic of McCullough’s standard of high technical expertise, of their technicians, on which we depend for our HVAC system. Between maintenance agreement and 2018 new system warranty, the few incidents of AC loss have been covered. The maintenance agreement is well worth the subscription price.

July and August 2023; James Sanchez & The McCullough Team provided reliable service for our 2018 new system described below. In June, 2023, during the annual AC maintenance visit, James showed us how to water the outdoor AC unit to remove dirt generated by water and sewer line construction which would eventually have become clogged and shut down. And, this July, James fixed our AC system when an electrical connection shut it down. Both visits were included in our annual maintenance contract that covers inspections and emergency visits. We will continue to maintain this very worthwhile McCullough contract.

McCullough installed our state of the art AC/heating unit in 2018. This unit has received yearly maintenance, except for 2020, due to COVID. This computerized system, provides readouts on the thermostat; alerts for replacing filters, routine maintenance due, and any system failure. It shuts down when any inconsistency in performance is detected preventing damage to major parts. There have been two instances of system failure, both under warranty. In each instance, McCullough answered our emergency call to restore AC in a timely manner. Yesterday, I was both relieved and impressed to receive text updates on their technician's arrival time. Herman quickly discovered the problem and restored the AC to running within an hour. McCullough has been consistently professional in scheduling, communication, and charges for maintenance. I am glad we used the same company to instal and maintain our AC/heating system. I highly recommend McCullough for installation and maintenance of a new AC system.

Townhome in Mueller.
I want Blake to come service my AC unit every six months.

Sam came by and gave me a second opinion from a previous AC company diagnostic. He showed me that was I was previously told was not accurate at all and completed a simple fix and got my AC back up and running while he was here. Very happy with Sam’s honest approach with his diagnosis and repair and how he walked me through everything he was looking at. Highly recommend.

Matthew Santos was extremely polite and knowledgeable. He was patient and took the time to explain each process. His work solved our AC problems. We highly recommend him and McCullough!

Makayla was so professional and courteous when she came to our home to fix the unit. Because we are about to purchase a brand new system, including all new duct work, we were not charged for this repair.

Thanks to Raul for a thorough and professional checkup of our HVAC system.
