Our Most Recent Service Reviews

McCullough and Shawn May came through where 4 other companies failed and fixed some terrible whole-house vibrations caused by a faulty blower wheel. Shawn gave us an honest, straightforward diagnosis of the problem and attempted the lowest cost possible fix before proceeding to more involved repairs. McCullough’s team was also very responsive and made scheduling/information gathering pretty painless. Great experience overall and will definitely be calling them for any future HVAC needs!

We had a great experience working with Evan Young as our project manager. We had to do an HVAC system replacement and he was super professional, easy going, and knowledgeable. All the pricing and info was simple and straightforward and we never felt pressured by any sort of upselling or sales tactics. The team focused on what we need and everything went smoothly. Especially appreciate the follow up quality inspection a few days later to make sure everything was on point. Highly recommend McCullough!

I have lived in my home for 20 years and recently had for the first time, a complete home plumbing inspection by James Farr from Mccullough. The inspection report was very valuable and informative. The plumbing was in much better condition than I was expecting. I was very happy and satisfied with the report. James did a very extensive look and testing of everything. His report included understandable assessments and a game plan with options for eventual improvements. James' demeanor was very friendly and professional.. I was not pressured at all to make any kind of immediate decisions which was so appreciated. I use Mccullough presently for my HVAC service and now do the same for plumbing services.

Blake was amazing. Very professional and thorough with the maintenance! McCullough always sends amazing people not just very professionally but also very interesting human beings.
We have been very happy with the company and the service and the people

Very professional, and solved the issue quickly.

My first time working with McCullough, and it was an overall great experience. During the first heatwaves of this summer, my 6-year-old HVAC unit broke down, and I struggled to find an available company to inspect it within the same week. Understandably, it was a busy time of the season. After reading several positive reviews online, I reached out to McCullough.

Initially, I found the interaction with the AI voice to schedule an appointment a bit unusual, but I was pleasantly surprised by its accuracy. It quickly understood the problem and scheduled a next-day appointment within seconds. Technician Kyle Sterling arrived that day, and he truly deserves the praise for his work.

As someone with limited HVAC knowledge, Kyle took the time to explain the issues in detail, the necessary repairs, and the cost which was a better deal compared to a couple of other quotes I had received. Kyle’s expertise and attention to detail made the entire process smooth and informative, and I felt confident in his abilities.

He scheduled a day for repairs, returned with assistance, and completed the job as scheduled. Kyle even discovered an additional issue with the HVAC system (a faulty coolant valve) and didn’t charge me for it. He didn’t charge me for the repairs until everything was resolved and the unit was up and running.

Overall, it was a great experience. The repairs were fast, and the technician was excellent.

Matej did an Excellent Job. He takes great pride in his work and it shows. Exceptional plumbing skills.

Jaiden did a wonderful job brainstorming and finally (after 3 other techs) figured out what was causing issues with my system. He kept at the troubleshooting until he got it right. I was so thankful for his persistence trying to solve the issue. Went above and beyond!

McCullough Heating & Air Conditioning did a great job. Josh Henderson and Matthew Santos were knowledgeable, courteous, and diagnosed + repaired my AC unit efficiently. Would definitely recommend.

Warranty repair was handled quickly and easily. Quick diagnosis, ordered part, and repaired within 2 days.

Nice guy

Excellent communication, excellent quality of work, fair pricing. Would highly recommend.

Shawn May did a great job with a maintenance check at our property. Very professional, friendly, and knowledgeable. Did a great jov. We highly recommend McCullough !

Blake is the man!!!

Craig was awesome! Very easy to talk to and communicate with, friendly, and addressed my concerns immediately and even educated me on additional problems that may occur. Excellent work!

Jaiden Mendez was very helpful and fixed our issue quickly!

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.

Blake took the time to show me the state of the inside of my coil and give me options for getting it cleaned. I ended up becoming a member because it is a very good value.

Miko was very thorough and courteous, put on protective booties when entering our home . Flushed the condensation line and checked all readings on the air handler and outside condenser unit. Miko also top the time to pair my phone withe the ecobee stat.

We had two issues emerge in our system. The first was a short in the compressor caused by ants getting inside the electronics panel requiring a connecter replacement. I called on Wednesday late in the day and Shawn came out first thing the next day explained the issue and fixed it. Very helpful.

Unfortunately our blower on the same zone indoor unit went out that weekend, possibly a coincidence or could be a short that fried a component - I called and asked to speak to a supervisor to understand the issues and he called quickly and was very helpful.

Jaiden the diagnosing tech on the blower was back out yesterday and installed the new part and gave me a heads up on other items to be aware of. Pricing is bundled for the parts and labor and based on my research was very fair. These systems break and having an existing relationship with a company w a maintenance program to me is essential so you can be prioritized during periods where things back up. McCulloch maintains the scale to support its client base. I appreciate that as they were there when I needed them.

I've worked with McCullough for a while now, and it's been a fantastic experience from day one. Everyone on the team is professional, responsive, and genuinely cares about providing great service. It's refreshing to work with a company that consistently follows through and makes things easy.

Kassidy and Malori has been especially great to work with. She's always positive, incredibly helpful, and communicates exceptionally well. She makes every interaction simple and stress-free. I truly appreciate everything she does and would highly recommend team McCullough to anyone looking for a company they can count on.

Eric was super amazing, knowledgeable and extremely polite and professional!! He went above and beyond to sort out the issue that was occurring with our HVAC system! I will definitely recommendation him and McCullough to my friends and neighbors!

Kyle was quick and efficient. He answered and addressed my concerns this week. I am happy with his diagnosis. Good work!

Great experience, would recommend! Diagnosed issues quickly and was able to address same day!

They were awesome.No complaints.

Miko was very thorough and courteous, put on protective booties when entering our home . Flushed the condensation line and checked all readings on the air handler and outside condenser unit. Miko also top the time to pair my phone withe the ecobee stat.

McCullough has proven time and again that they are reliable, honest, and thorough with their work. We have used them several times over the course of these past few months - Jayden Mendez was the HVAC technician that we had been assigned and he has demonstrated efficient evaluation, troubleshooting, and repair of both our aging HVAC units whilst performing routine maintenance. We appreciate all of his hard work!

Kyle was very professional and completed the job at a very high level.

Miko was an exceptional technician. He showed up to check on my unit and do services to it. He was professional and courteous. He explained what he was doing and a detailed breakdown of how the unit was operating. I am once again extremely satisfied with McCullough and the amazing technicians they have sent my way.

Matt provided a prompt and thorough estimate.

Miko was great today. Very good service.

Miko came to do my yearly cooling system checkup today and did a great job! He checked out my system and was able to find a couple small issues that he promptly fixed before they began causing me problems. He also helped me save money in the long-term by informing me of the benefits of signing up for the service membership plan! Thanks!

Blake was on time, answered all my questions, and got us back on the right track. Thanks so much!

Miko was very pleasant and knowledgeable. He took care of everything on maintenance. He explained everything to this old lady!

Blake was great! Very helpful! Checked my system and did some maintenance for me.

Responsive and easy to work with- thanks

Miko was thorough and went over everything he did on my yearly maintenance call.

There were A+. Miko was very helpful and knowledgeable.

Technicians Craig Plank, Juarez were both professional and explained everything thoroughly. They had my AC running and doubled checked everything before they left.

My technician, Ryan explained what was needed and was fast and efficient in getting my A/C running smoothly.

Mike Mctaggert did a very professional job ordering our replacement coils that were replaced under warranty and providing temporary repairs - The McCullough team was great in providing a cooling solution for our home until the part arrived from the manufacturer - We are grateful for the teams help - thank you Ethan, too!

Ryan inspected and assessed my A/C and found my unit was clogged, but everything else checked out ok.

Mccullough delivered a prompt repair at a fair price in the heat of summer, and techs Craig and Thomas were very considerate. Plus, Craig pinpointed a tiny gas leak in my attic--a true service. I am so grateful.

Great job! Very nice personality.

I cannot recommend James highly enough. From start to finish, he demonstrated the professionalism, expertise, and attention to detail that every homeowner hopes for but rarely finds. He took the time to thoroughly assess the issue, clearly explain the work that needed to be done, and completed everything with exceptional craftsmanship and care.

What truly set James apart was his personable and approachable demeanor. He was patient in answering questions, respectful of our home, and made sure every detail was addressed before considering the job complete. His thoroughness and commitment to doing the job right, not just quickly, was evident throughout the entire process.

In all my experiences with plumbers over the years, James stands out as the best master plumber I have had the pleasure of working with. McCullough is fortunate to have someone of his caliber representing their company. I would recommend James without hesitation to anyone looking for a knowledgeable, trustworthy, and highly skilled professional.

Sincerely,
John P. Marshall

Mike was incredibly timely and proactive about communicating. I really appreciated his pre visit call and prompt service. I’ll always use McCullough for HVAC!

Words cannot fully capture the gratitude I feel for the outstanding work and attention provided by McCullough Heating & Air Conditioning. From the moment my call was answered to the efforts of the sales representative, technicians, inspectors, and customer service team, every interaction was marked by professionalism and genuine care. The passion and dedication they bring to their work are truly exceptional.

My experience with McCullough has been nothing short of remarkable, and I am eager to share their excellence with others. Thank you, McCullough, and the technician Miko for transforming my home into a more comfortable and enjoyable place to live with your incredible cooling and heating system.

Michael McTaggart came and diagnosed & fixed my ac problem. He was very informative and explained things simply! Thank you so much! Yay!

Milo did a great job with our service of our AC units. He was prompt, explained what he did, health of the units and everything related to the costs. Definitely recommend!!

Our 20-year-old residential HVAC system was functioning but not at an optimal level. Kyle and team arrived within the scheduled time frame and performed a diagnostic within the first hour. They identified the source of the problem and Kyle walked me through a list of recommended repairs to get the machine working at its fullest potential. We both acknowledged that the machine would likely need replacing soon, so he documented system specs to aid that process. Kyle and team were friendly, courteous and very professional. Thanks!

McCullough installed a new HVAC system for us last year and we just had the first of our annual services - we couldn’t be happier with their service so far. Troy was an encyclopaedia of knowledge during the original installation, and since then their crews / service staff have always been friendly and knowledgable + it has been easy to schedule any appointments needed (all of which have been under warranty so far).

Update: Blake who did our service today was an outstanding technician. Very patient and easy to talk with and ask questions to, and overall did a thorough job with our routine maintenance appointment.

Blake was great!!! Went above and beyond and explained everything.

Eric was great technician. Explained everything very clearly and wasn't interested in upselling me on anything. I totally appreciate the honesty and solid workmanship. Thank you McCullough for another great experience start to finish.

Sean was an amazing, super helpful technician!

Very high quality and courteous technicians in plumbing as well as AC, thanks to Matej!

Unfortunately, the time finally came for my girlfriend and I to have to replace our air conditioning system. We called four different air conditioning companies for quotes. Each one sent out some high pressure salesperson promising discounts to sign right away and that couldn't answer many of our questions. Then McCullough sent out Evan Young. Evan took the time to answer our questions honestly and methodically. Throughout the process, he was patient with us and never pushy. Price wise McCullough fell in the middle but knowing our replacement was in good hands with Evan and his crew of Mark and Christian made the decision to go with them easy. I will be recommending Evan and McCullough to all my friends and family if they should be unlucky enough to have to replace their system.

Very professional, nice , Honest and I would definitely recommend McCullough heating air and plumbing. Needed a plumber and was happy to see that mccullough has plumbing needs. Matej is very knowledgeable and explained the entire process.

Craig did a great job diagnosing the problem. This will be covered under warranty since the copper pipes were just installed 2 months back and the welded connections are already leaking.

Kyle was timely, knowledgeable, friendly and very efficient. He made recommendations to make our ac unit more effective. We’re very happy with his work and McCullough

A little bit of context: house built in 1994, has two AC units, a big and a small. Changed the big one in 2009, which started malfunctioning last week. Both units have been serviced annually by a certified technician. Technician checked the failed unit, which was acting intermittently, and recommended we find a certified Carrier technician to check it. Through Carrier we found "McCullough Heat & Air" which sent Kyle S. over the next day. Being an electrical engineer myself was very pleasantly surprised with his debugging skills: after testing all the components and the communication between them, root caused the malfunctioning to the "comm board" on the outside unit. With most electrical intermittent issues it's very hard to be 100% sure. Trusted his knowledge, ordered the board (on the expensive side) which he replaced once it arrived and now everything is working.

Overall very satisfied with service and especially with Kyle; highly recommended at least for complex cases like this. Glad we found someone we can trust with the AC.

Bryan replaced a blower motor quick kike a bunny - it was free!? Still in the warranty window. I would have gladly paid them - And that may be the point. Those guys are the absolute very best. 25 years of being a customer. And not a roller by any means..

Miko was awesome!

Blake did an outstanding job for me and was very courteous. I appreciate his prompt service and how helpful he was for me. Thanks so much.

Kyle had to come out to replace a bad compressor on our new unit. He was able to get us in during normal hours on the day we called and the communication during the process was very good.

McColloughs technicians are always knowledgeable and helpful. I have depended on them to complete emergency repairs in a timely and diligent manner and Michael’s work today was no different.

The technician (Craig) was very friendly and got right to work. He was very responsive to several questions I had about maintaining our system.

Awesome service as usual! Craig is very knowledgeable and friendly and knows exactly what to do for your a/c needs with complete step by step details. McCullough is the only way to go!

Blake was very helpful in explaining what we needed and how to take care of our system. He fixed it very quickly and was professional!

Love the McCullough people always!
Josh was able to get my issue resolved quickly and up and running! Superior people, superior service❤️

I had a great experience with McCollough HVAC during my regular maintenance service. Chris Miko was thorough, professional, and kept me informed every step of the way, explaining what he was checking and why. He identified that the system needed additional coolant and took care of it efficiently.

I was really impressed with Chris's attention to detail, clear communication, and commitment to making sure everything was running properly. It's reassuring to work with someone who takes the time to do the job right. Highly recommend Chris Miko and the McCollough HVAC team!

Mike was great and professional. We got the repairs done in time and reasonable price.

Excellent service. Knowledgeable tech. I signed up with the maintenance plan because it makes sense with the crap equipment thats made now....and McCullough is a quality local company.

Great first experience. Mr. Ischy was focused, kind, very informative, and super professional. We’re glad to have his expertise!

Great experience. Mr. Eastland was focused, kind, very informative, and super professional. We’re glad to have his expertise!

Our air conditioner went out on Saturday, July 4th. It was very hot! I called McCullough and the sent our Jaden Mendez. He got there amazing only about an hour after I called. We had a wiring issue. He had our system rewired, back up and running in a less than 30 minutes. Great, fast, and very reasonable service. I highly recommend!

Prompt, punctual, professional. Very impressed.

Blake did an outstanding job for me and was very courteous. I appreciate his prompt service and how helpful he was for me. Thanks so much.

We worked with another company to do a HVAC check up and they didn't clean out the drain line as they should in a routine service. There was a major leak from the drain line and the whole unit had to be shut off and my business closed until it could be repaired. The other company (rhymes with "vans") stated they could not come for 5 days. McCullough offered a holiday emergency appointment (for extra cost) and repaired the issue quickly. They did a proper servicing of the unit while they were there. Josh- the technician was helpful and attentive. Thank you, McCullough.

Super helpful and fast! Showed us how our unit was still under warranty so we could save money. Love this company

Mike was super efficient, very kind, and informative on every step of the process as he got our AC back up and running for us.

Mike did an awesome job - he came out last minute on a national holiday and got our AC back in shape in no time at all.

5/5 Would definitely recommend.

Shawn May came out and was able to diagnose and fix the issue quickly! Super grateful!

McCullough Heating and Air has been an outstanding company to work with. They are responsive and fair. In particular, Jaiden, a recent technician gave great customer service on a repair issue.

Michael at McCollough is the truth - we’ve called nearly every service in town, this is the first time we’ve gotten a thorough diagnosis of the problem and an option to repair instead of replace. Still family owned and it shows!

McCullough has been wonderful!

We purchased a new HVAC in the summer of 2023, and had no issues.

Brian performed a routine PM on the system in May 2025 and everything is doing great! Thanks Brian, and McCullough!

Zach is also great and just made sure our system was winter ready!

July 2026 - Jaiden just stopped by on the morning of July 4th to help clear a condensate drain line. He was able to diagnose, repair/replace and have our system up and running within 30 minutes! Thank you Jaiden, and thank you again McCullough!

My A/C unit began having issues the day before the Fourth of July weekend. I called about 10 places and finally was recommended to McCullough by another local tech. Scheduling was simple and automated. My tech, Micheal, was amazing! My unit gave out completely and Micheal called me in the afternoon to let me know his ETA. He arrived earlier than expected and went right to work. The issue was resolved both quickly and efficiently. He even took the time to explain the condo’s HVAC system and answered all my questions. At 5p on a Friday during a holiday weekend, I couldn’t have asked for better service. I’m extremely pleased and highly recommend this company.

Jamie was a great plumber to help with a suddenly leaking hot water heater that needed to be replaced. Super professional, talked through and priced different options, and got the replacement done the same day. Will absolutely use him again.

Delightful and knowledgeable

Josh was very friendly and knowledgeable

Very pleased with everyone we interacted with at McCullough - from scheduling people to estimator, to installers to QA inspection. Very professional and courteous. We replaced an aged AC/furnace, ductwork, insulation and weatherization of doors, etc. We took quotes from two others and no regrets going with McCullough. Chris did an excellent job explaining options and recommendations - never felt like I was being sold.

Another great experience with McCullough Heating, Air Conditioning, and Plumbing!

Blake Eastland went above and beyond to make sure my HVAC system is ready for this Texas heat.

The unit in my attic had a lot of debris from a roof replacement and Blake swept that off for me. He also helped me cut tree limbs that were rubbing against my outdoor unit and my roof. That's 5 star service for sure!

Blake was a pleasure to work with and I would gladly recommend him!

The folks at McCullough are so helpful and kind! All the technicians are great- the guy who helped me when my AC was broken (I had spoken with two other ac companies) was straightforward and gave me real info rather than a sales pitch (I think his name was Matt).

Since then, they have helped me out with a couple of small issues that I’ve had with my new unit. The last Tech that I worked with was named Thomas and he was awesome as well! Very respectful, personable, and informative. I always feel comfortable with the technicians being in my house.

I’m glad that I went with McCullough- they will continue to have my business!

Locally owned, friendly service, efficient work. They're just great!

I have confidently relied on McCullough to install and maintain my home HVAC systems for over 20 years.

My service was great, the technician was very informative, and very helpful. I feel good about the state of my AC unit and how to keep it happy and running in the future!

Blake gave Great service! Gave us some tips as well, was efficient and very professional!

Amazing service with our technician, Josh! He was knowledgeable, courteous and professional. Highly recommend McCullough Heating & Air!

Amazing experience with McCullough! Our AC broke on the hottest day of the year. McCullough was out there the same day, diagnosed the problem, got the needed part (and confirmed it was covered by warranty), and was back the next day to fix the unit. Down time less than 27 hours! Special thanks to Eric Suarez, who did a great job with the repair!!

Blake was very informative,respectful and polite my appreciation

I had a clogged drain in my AC unit that Thomas diagnosed and corrected the situation timely. Thomas explained the cause and how to have it not happen in the future. Thomas took the time to fully inspect my unit inside and out.

Blake is efficient and a good communicator when we had a problem. Great service!

Blake was really great

Miko was friendly, he listened, understood my concerns and issues. He did a great job on a diagnostic testing, and we found the issues that we confirmed together were the problems. He found a way to solve it, That was in my best interest financially as well as for my air-conditioning system. Miko explained to us what the problem was and what systems needed to be fixed in a language that I could understand. He showed us the issue and the high numbers effecting the efficiency of air conditioner. It was very important to us to feel like we had a company that really cares about your needs, is honest and has great expertise. thank you McCullough and thank you, Miko.

Miko was thorough, personable, good questions about the systems , excellent clear answers. Hard worker, top notch.

Excellent work and courtesy service .well worth membership

Highly recommend! Josh was very professional and had my A/C back up and running in no time.

Exceptional service experience with Miko. Very knowledgeable, thorough inspected and maintained our multiple HVAC units, provided guidance on maintenance and advice on unit status. Explained all work clearly and thoroughly. Quickly got our units back to optimal operation when a couple of issues were identified. Overall fantastic service and customer experience! Thanks Miko!

Josh really knew what he was doing & did it well

Blake was a great tech! Caught that my drain line was clogged and blew it out. Had other helpful suggestions too!

I love this company! They put out real effort to get you scheduled for your routine maintenance, allowing flexibility to request either morning or afternoon service. Their technicians are friendly, polite and communicative., esp the one who came today! Nasar Barenji. He came early, was super nice, exceptionally competent and emphasized the critically important repair another one of McCullough’s routinely excellent technicians had recommended a year ago at my annual summer inspection that I could not afford at the time to authorize. They are all doing their best to help me extend the life of my aged HVAC system.

Miko was excellent. He came for a simple service call but soon found multiple issues. He worked late into the evening hours determining what was wrong with our system.

They were busy and our technician was able to come on the later end of the time window but they texted to let us know, completely understand in the summer heat. Jaiden quickly diagnosed and fixed our A/C unit. Thank you! Will use again.

Mico was friendly, efficient and thorough! Highly recommended.

Came by to perform a health check on my AC unit, very knowledgeable and cordial highly recommended.

My AC was not working, I called McCullough. First time using them, and it won’t be my last. Craig came out did a simple diagnosis that are drain was clogged, Unclogged it same day, then cleaned the drain and all the other drains we have.

Craig was very polite, calm, and professional. That’s usually the type of people you want working on your home.

Thanks for everything Craig, I’ll be requesting you next time!

Bryan Hermawan was great

Showed up on time. Fixed the issue quickly and charged a fair price. Josh was exceptionally friendly.

Quick and efficient check of my A/C with estimates of maintenance to improve efficiency and prevent problems in the future

Amazing work by Matij. Very personable and clear in what needs to be done. Reasonable response from McCullough (not a fan of the AI bot for scheduling).

What can I say. Mike McTaggart was skilled, polite and on his game. We had no AC in the house on a 95 degree day with +90% humidity and Mike quickly diagnosed the problem and replaced a fried capacitor and got us back up and running within the hour. What a fantastic emissary for the company and what a talented professional. I highly recommend McCullough and of course Mike (a.k.a the Other Oracle of Omaha). Great job Mike. If I could leave a 6th star I would.

Responsive and easy to work with! Eric was very helpful and helped us avoid big(ger) problems.

Ryan Lake did a great job and thoroughly explained the issues he found while repairing our system. He arrived promptly, texted us a photo so we knew who to look for, and was kind and professional. He discussed some options for improving home maintenance of our system, which we found very helpful. We trusted McCullough to install our system and we trust them to repair it!

Just ha 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!

Respectful, thorough,in short great.

Blake was great. Good work!

We have always had a great experience with McCullough Heating and Air. When our system had issues in the very beginning of summer, they were able to respond very quickly and our first technician Josh Henderson, was very helpful in addressing the problem within the same day. Then, we later had a preventative HVAC inspection and some corresponding service done by Blake Eastland. We didn’t feel any pressure to purchase the services, but rather informed about some potential options to help mitigate the issues with how the new construction home builders cut serious corners with the installation of our HVAC system. It’s never fun to have to put money into air conditioning, but McCullough made the process as painless as possible. Would definitely recommend them

After Henry Harris, Shawn May was assigned by McCullough to complete the repair of my AC system which had a leak. He worked hard to make sure that the leak was repaired properly so that my AC could function properly. He was professional and friendly. I commend him for the job that he did. My AC has been working smoothly after the repair job was completed.

I had an EXCELLENT experience with James and Matej from McCullough Plumbing today!

They thoroughly examined my entire plumbing line and went through every step of the process with me. They gave me good recommendations and explained my options clearly.

Not only were they great professionally, they were also very kind and had a delightful sense of humor!

I definitely recommend these guys!

Josh Henderson worked on my AC system. The thermostat kept rebooting by itself and the system would shut down. He found the problem and fixed it at a very reasonable price. Very competent technician highly recommend him.

I have confidently relied on McCullough to install and maintain my home HVAC systems for over 20 years.

Miko did a great service is knowledgeable and very professional. I trust for servicing my unit in future

Eric Suarez was great. Very Knowledgeable very professional!

The monthly service package is a life saver.

McCullough and their service person, Thomas Ischy, were fine. They were responsive, timely, efficient and professional, as they have been every time we’ve used them.

Miko provided great and professional service. Highly recommend.

I came home from being gone for a few days and it was 88 degrees inside my house in July. I immediately called McCullough and technician EJ Pittaway was at my place almost within an hour. My AC was fixed and running properly in no time and the cost was moderate. I had anticipated at least 24 hours of misery but McCullough fixed my problem within 2 hours of my return home, and EJ explained everything to me and showed me the gauges and diagnostic tools he used. They are my heroes.

2026-06-24 Eric Suarez diagnosed and serviced our system today. A bad capacitor was causing the compressor to make a thrumming noise. He carefully checked, repaired, and rechecked everything. Inside, he checked that each zone was producing cool air. He was thorough and clear in his explanations. I asked about shading the outside unit, and he explained how a shade cloth, at least 7 feet above the unit, provides excellent benefits.

We are well satisfied with McCullough service. All the technicians we've met over the years have been excellent.

McCullough has given us great service for many years. Today's (2026-04-27) summer season inspection was exceptional in attention to detail. In addition to all the required checks and settings, they hosed off the compressor. They concluded with a review of photos of all critical parts and their manufacturer-documented settings, compared to today's actual readings. They were within tolerance throughout. Thank you!

Quick and efficient service, well explained. Update 2024-11-05, Joe was most helpful with a quick and thorough seasonal inspection. He also gave great advice on when to repair our now aging system.

I've used this company more than once. During a recent service call, the technician Kyle, was thorough in inspecting the system, attic, ductwork, and outdoor unit. Although the issue ultimately did not appear to be HVAC-related, I appreciated that he was honest about what he found and referred me to another company rather than recommending unnecessary work

Amazing service and pricing. Clayton and Craig took good care of us!

Very appreciative of Bryan and the whole McCullough service. I took advantage of their $99 service special and all was great. Bryan flushed out the AC drain pipe, adjusted the Nest thermostat, and checked the pressure and bells/whistles. He was very knowledgeable, efficient and friendly. All good. Thanks!

Josh was great! Friendly, polite, quickly got the work done, and explained things thoroughly. Thank you!

Very thorough plumbing inspection fully complimentary for being an annual member for the HVAC side. They did dye tests on all toilets, checked sinks, and water heaters. Did water harden tests along with chlorine levels and made valid recommendations. The combination of master plumber James Harr and soon to be master plumber Matej Bzdil made the inspection quick and easy. Highly recommend and will use them again!

My old HVAC system was at the end of it's life in 2024. After a few estimates, I chose McCullough to replace it. A 2-stage 2 zone Carrier system was installed and has been a great decision. Because of problems with the original ductwork, everything feeding the second story was also replaced. The new system is very efficient, reducing my cooling bill significantly. A small problem popped up and the technician was able to diagnose and repair it very quickly.
The price was reasonable considering the extent of the work. I enrolled in twice a year maintenance and have had no additional costs.
It's a great company with well trained and considerate people. I highly recommend McCullough for installation, repairs and maintenance.

Miko. Showed up for my ac tune up.
He was professional and to the point.
I'd recommend McCullough.

Good communication, fast and thorough work. Thomas was great- fast and thorough! Thomas also came back and made sure a drainage leak was also fixed. Highly recommended!

Blake was my service tech for semi-annual system maintenance and he was punctual, polite, knowledgeable and helpful. Five stars!

Seamless and professional experience with McCullough! Our tech Blake was easy to work with and explained everything he did. Showed up during the time frame, easy to communicate with, and was professional.

Recently Henry Harris was assigned by McCullough to check my AC system which had a leak. He made three visits to my residence and made sure that he found the source of the leak. He was professional and friendly. I commend him for the job that he did. He left good pictures and made it easy for the repair technician to do his job of fixing my AC leak.

I came home from being gone for a few days and it was 88 degrees inside my house in July. I immediately called McCullough and technician EJ Pittaway was at my place almost within an hour. My AC was fixed and running properly in no time and the cost was moderate. I had anticipated at least 24 hours of misery but McCullough fixed my problem within 2 hours of my return home, and EJ explained everything to me and showed me the gauges and diagnostic tools he used. They are my heroes.

Ryan helped me diagnose the issue and was extremely knowledgeable and took the time to explain what was occurring, my options, and next steps. The whole McCullough team was a pleasure to work with and fit me in very quickly, which is important when your AC stops working in summer in Texas!

Mico is great guy

My AC went out this afternoon and McCullough was able to send Michael out after hours to fix. It was an easy fix, but he made sure to check everything so he knew what caused the outage. I appreciate the thoroughness!

Excellent service and an expert team! Miko was kind, professional, and thoughtfully explained how my system could be improved while encouraging me to take time before making a decision. Very respectful and did high quality work. Recommended!

Craig came out to our house today and I could not be more grateful, he was incredibly knowledgeable, kind and courteous and he diagnosed the refrigerant issue in our AC unit within 60 seconds of looking at our unit. He went above and beyond and was incredibly thorough, testing everything afterwards. Honestly the single best experience I’ve had with an hvac company.

Kyle did a great job of inspecting our AC, recommending improvements, and completing the work expeditiously. He also told me about a program for twice-yearly HVAC inspections that would, in the long run, save money.

Shawn May came out and was able to diagnose and fix the issue quickly! Super grateful!

Mike did an amazing job fixing our broken AC on a hot Sunday in Austin. He explained the problem and its solution very clearly and even did some extra maintenance for us. Fantastic experience! We have been very happy customers of McCullough Heating & Air Conditioning.

Michael came out on an emergency call and accurately diagnosed our leaking air conditioner unit and made suggestions to repair and alleviate the source of our problem. He was punctual, professional, and had follow up repair work scheduled upon completion of the service call. McCullough always comes through for us.

Excellent, friendly and fast service. Mike was a great technician. Great quality and great pricing! I will definitely continue to use them.

Excellent service! The technician was professional and knowledgeable. He fixed our AC and made sure everything was working perfectly before leaving. We really appreciate the great service and would definitely recommend this company!

Technician was very thorough and explained everything to my satisfaction. I always use McCullough. Wish Mico could come out every time. Please give him my regards for a job well done.

Blake was helpful and explained everything. He went above and beyond on a routine maintenance visit when he discovered my drain line was blocked. Update: later in the day, the AC stopped working. Mike came out today and thoroughly cleared out the drain line and got the AC working again. He was extremely helpful and professional and made an adjustment that should prevent the line getting blocked in the future. Super customer service!

Had a service call today with the technician.Michael, he came out promptly at around 8:15 AM.He.Identified the problem relatively quickly , with my compressor having an issue and was able to set up an estimate this morning so we can get the process expedited and taken care of I truly appreciate my call coming out with such urgency.This morning and getting me a resolution before this afternoon

Michael M was great and quickly identified the issue we were having. his knowledge of the mini-splits is very thorough and he gave insightful tips on optimizing their operation.

Great service!!

Responsive to concerns and each service person is very professional. I do not trust "AI Jane," since I recently left a couple of "urgent" messages with her and a service person wasn't dispatched until I got a human. They are "tweaking" her to be more accurate.

Kelvin from McCullough Heating and Air came out for a deep-dive evaluation of our system and was excellent from start to finish. Rather than just pushing me toward an expensive fix, he walked me through every step of his diagnostic, ran real troubleshooting, and even reached out to colleagues for a second opinion to make sure we got it right. He was friendly, thorough, and genuinely investigative — a real problem solver who clearly cared about understanding the actual root cause instead of guessing.

What stood out most was that he didn’t want me spending money unnecessarily. No gimmicks, no upsells, just honest evaluation and straightforward solutions. My last company did just the opposite, which is how I ended up needing a second opinion in the first place — so Kelvin’s transparency meant a lot. He earned my trust and my future business by delivering real value. If you want someone who treats your home like it’s their own and gives it to you straight, ask for Kelvin. Highly recommended.

Good communication, fast and thorough work. Thomas was great- fast and thorough!

Mike our technician replaced a bad computer board. He is very polite and knowledgeable. Will always use McCullough for our HVAC needs. Thank you

Blake did my HVAC summer maintenance check on 6/19/26. He was prompt, courteous and thorough. Provided pictures of what he saw and work that was done. Provided 90 day estimate for possible compressor problem to my email. Will schedule for future date. Well done!

Blake was super helpful and explained everything! He went above and beyond on a routine maintenance visit when he discovered my drain line was blocked.

Great support! The technician stayed on the job until he had verification from Trane that the part was in stock and could be quickly shipped to repair my AC.”

Chris Mika was great! He was very polite, friendly and professional. He showed up promptly and was thorough checking both of our AC units and clearly knowledgeable. He was respectful and not pushy. Highly recommended!

Mike M is absolutely stand out solid - motivated, knowledgeable and incredible work ethic. If he plans to branch off with his own team/co I’ll be first in line to invest. Above and beyond squared

I am very appreciative of your technician Jaiden for making time after a busy day to come repair my AC in the late evening. He quickly diagnosed the problem and fixed it that evening. He is very professional and provided excellent customer service. I highly recommend Jaiden to anyone needing AC/ heating service. Thanks again Jaiden!

Thomas did a great job getting to the cause of our problem with the Ecobee Comfort settings and correcting the problem. He was also very patient and helpful guiding us through the menu of options and settings related to the problem.
In addition he helped us with our concerns about the Ecobee air quality monitoring and provided useful insights into possible causes and solutions.

Technician Shawn May went over the top for us. After initial inspection and component replacement, it was determined and another component was the root cause. This was late afternoon so he called someone at McCullough to reopen the warehouse so he could get the AC up and running that evening. That’s the kind of service McCullough provides. They replaced our complete system when we bought the house and have stood behind their work every step of the way. We honestly couldn’t be happier.

Blake provided friendly and efficient service.

Eric Suarez did a great job of installing some new equipment and is friendly, helpful and efficient. McCullough always provides expert service and first-rate equipment!

We had an issue
Diagnosed same day and temp fix
Replacement yesterday and team was great
In our time of need they met our challenges
Highly endorse
Pictured here are Mark and Christian. They were both incredibly hard working, very neat and extremely fun to talk to. They set the expectations, regularly communicated progress and discussed options. I felt so comfortable that I left for a few hours to run some chores for the house. They built and earned TRUST!

Josh quickly diagnosed the problem as a bad switch, and he was able to quickly replace it for a reasonable price. A/C was back on!

Blake was fantastic! We will ask for him specifically next time we use Mccullogh!

Miko

was efficient very friendly courteous, and did an excellent job. I highly refer him.

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.

Evan and his team at McCullough Heating and A/C were professional, courteous, knowledgeable, and efficient. I highly recommend their services.

Friendly and professional.

Eric was exceptional. Today he reset my complicated new wifi-connected thermostat that had gone offline and taken my AC with it, and then taught me how to do that myself. He spent time checking all possible causes for the outage, patiently explained the process, answered my questions, and provided a solution: surge protectors to prevent power surges or brief outages from knocking out my thermostat and HVAC again. He also took time to show me features I’d been unaware of so I can make the best use of my new HVAC system. He also checked output and temperatures at each vent and was able to cool down the warmer rooms. He was courteous, knowledgeable, and kind, and left me feeling reassured of McCullough’s excellent service and moral support.

Just finished my project and had a great experience overall. I shopped around with all local, reputable companies and McCullough really blew everyone out of the water. My project manager Peter was knowledgeable and had a no pressure, educational approach. He was the only sales rep that took the time to fully explain the Austin Energy rebate program. By leveraging the program, I was able to get a new dual stage HVAC unit, attic insulation AND brand new duct work for less money than the next best priced proposal that only included a new unit. The rebate program also offers 0% interest financing for 10 years, which was by far the best financing offer from all the bids I received. All of the install technicians were very professional and courteous. Jimmy the supervisor ensured everything was up to their high standards of quality and inspection ready. You will be hard pressed to find another company in Austin that is not private equity owned, has a no pressure/professional sales process and high quality installation for a great price.

Miko was knowledgeable and informed us of every step along the way. Will use again

Blake completed our semiannual service check. He worked efficiently, was courteous, and answered all questions.

Blake with McCullough Heating, AC & Plumbing was fantastic! He was prompt, polite, and kind. He was also in constant communication as to his arrival and explaining what the maintenance visit entailed. He explained pricing and ended up saving me a ton of money. Thank you and highly recommend!

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.

Shawn M. was very thorough and knowledgeable and we appreciated the repairs to our unit quickly and efficiently - we called and they were out the next day. Thanks for your help!!

We had dampner issues that was preventing our A/C from cooling zones across our home properly. Kyle was great. He listened to our issues, diagnosed the problem, explained what was broken, the fix, clear next steps, costs, scheduling and took care of the repairs. He was also very respectful of being in our home. Would definitely recommend. Glad we were able to get this sorted out before it got really hot this summer. We ended up signing up for maintenance contract moving forward which came for a discount on our repairs. We were able to get someone out immediately. Recommend scheduling through website instead of talking to AI Jane when calling (that was the only issue lol).

One of the best experiences I have had with service professionals coming to our home. Ryan, the Technician, communicated when he was 30 minutes away, efficient, professional, wore covers on his shoes, took pictures of everything he saw in the attic, solved the problem in 30 minutes. Will definitely use this company again.

Excellent service done by the great experience service man. Thank you for for your honest advise when working and solving my problem.

Craig did a great job and was so nice and polite. I really appreciate how fast I got service after calling on a Saturday. Thanks so much for a job well done..

Craig Juarez was professional, polite and fixed my AC unit quickly and got my thermostat back online. I am cool again. Texas summers are brutal. Thank you Craig. The main office was reacted quickly to my request.

Blake

We had a routine inspection with McCullough Heating & Air and Blake was great to work with. He made suggestions and recommendations for what may be needed in the near future, without trying to pressure or upsell us- which was very genuine and appreciated. Prompt, professional, quick and easy- overall great experience.
