Our Most Recent Service Reviews

Was referred to McCullough by a friend who has used them for years. We just had a new system installed by another firm and our new rep found quite a few things that he adjusted that have made a difference already. Our old firm got bought by a PE firm and service was more about speed than quality. We have found our new preferred HVAC provider.

Scheduled an appointment online for a leaky a. c. and they were here the next day to make the repairs. Friendly service and fair pricing.

I certainly found honesty and professionalism in McCullough and Joey, the tech who came out. He blew out my AC lines thoroughly, and is wisely waiting to check all the electrical system because it was raining. He also changed my unit filter. I signed up for the maintenance program that McCullough offers. It is well worth the $16.95 a month because a McCullough representative will come out and check out your HVAC unit if you ask, and change your AC filter every 6 months. I highly recommend McCullough Heating and Air Conditioning, and specifically, Joey.

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.

Joey did a great job getting our thermostat set up and checking out our system. He provided very helpful feedback.

They were great!! They were prompt, friendly, and knowledgeable! I will recommend them to everyone! Kyle is wonderful and so helpful!

We had an A/C unit go out and we had a wonderful experience with McCullough installing a new heat pump. They guided us through our options and were extremely thorough and professional. Highly recommended!

Wonderful Service. My old air conditioner went out on a day that reached 100 degrees. McCullough Heating & Air was able to have Alonzo Olivas come out by noon. He was very knowledgeable and got the old air conditioner running and cooling again. He spent time explaining what he did and several options going forward. Great experience!

We had a great service experience for a recent issue with the AC unit. Appointment scheduling was a breeze; they explained the fees very transparently. The technician (D'Andre) alerted before the arrival, did a great job diagnosing, and fixing it. All of it was superior customer service attitude. Keep it up!

I wonder if I needed to have the entire air conditioning unit replaced given what the problem turned out to be…water back flow due to bad drainage Instillation of a pump was needed after replacing the entire unit Michael oefelein

This is a good company. Good communication, fast service, reliable with reasonable prices. Cant ask for more! Our technician Desmond took good care of us.

Alonzo was prompt and professional with my seasonal inspection. Good communication.

The tech was on time, friendly and knowledgeable. He provided us with suggestions to keep the unit in proper working condition.

I got outstanding service from McCullough on a complete replacement of my home HVAC system including two new Carrier Infinity heat pump units and two dual-fuel air handling units in my attic. Chris M. did a great job surveying, planning, and estimating the work and following up after the installation. Gilbert G. led two crews doing the installation and did a great job. It was a difficult job in tight attic spaces but to my surprise they completed it in one day with excellent quality work. The system is working great and is very efficient. McCullough exceeded my expectations for service and the Carrier system is performing very well. I highly recommend them for your HVAC needs!

Very favorable experience overall replacing two of our HVAC systems. Starting with the sales process, Alex identified duct and return work that was wrong in our existing system that was contributing to issues I was having and other firms did not identify these items. The installation team was efficient, knowledgeable and neat. There were a couple minor items I needed addressed after installation and Jensen, the installation supervisor, came promptly and addressed the matters. I will be highly recommending them to folks in my area.

The technician came out fairly quickly after we made the call. He was knowledgeable and polite; easy to work with. He fixed our problem in under an hour.

Replaced all of our commercial HVAC systems with McCollough. Great value, customer service, and follow through. Thanks to Troy and the whole team!

Competent technician. Arrived on time and serviced our unit expertly.

Quick same day service and feedback from the technician. Thank you Frank!

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.

Alonzo Olivas and McCullough Heating and Air Conditioning did an excellent job fixing my Carrier system. Alonzo was extremely thorough and detail oriented and did excellent work ! I will be going with McCullough from here on out!!

Excellent Service

My technical did an excellent job. He was thorough and explained all that he did, even suggested things to improve our unit.

Was really pleased with this company’s s service today. The Technician Frank was personable, proficient and honest. Am so happy someone recommended them. I immediately terminated my previous company. They were no comparison to McCullough.

There is nothing more comforting than having people working in your home that you feel are truly looking out for your best interest. Whenever Joel Galvan is in my home I feel like he is striving to ensure that everything is working optimally, while also being invested in cost optimization. When he is providing options for solutions, they always include cost effective information. Regardless of if that is a repair or replacement. His candor and transparency provides assurance on my part that I have all the information. He always goes the extra mile. McCullough has done a great job making me feel like they value my business and are invested in the practical and efficiency of keeping my HVAC systems maintained. They value my input and are very responsive. .

Very quality installation with a high attention to detail. Professional, friendly, and competent service as well.

We have been in our house for 40 years and McCullough Heating & Air Conditioning is the only company we have ever used. Always great customer service.

I had such a wonderful experience. My main point of contact was Joe who helped walk me through all options, answered (in great detail at my request) how HVACs work and all aspects of what I needed done. McCullough’s whole team was super responsive and often times bent over backwards to accommodate my other contractor schedules (home I purchased was in red of a lot of repair). I highly recommend McCullough for all your HVAC needs. They ROCK. I wish every contractor experience could be this pain free and easy P.S. they also sent a Tiff’s Treats box of warm cookies after everything was done

Frank was outstanding. He involved me in the repairs and made it very clear what the issues were and what the repairs would be. Only comment is the price for replacing the warranty part. I thought it was more than it should have been for the amount of work involved. But overall we are pleased with the experience.

Joey showed up as scheduled, was thorough, and diagnosed the problem quickly- very professional. I will be working with McCullough from now on.

They have been servicing our units for years and they are always very professional and very careful to not track dirt in our house they’ll always be servicing our units.

Great service and attention to detail. They diagnosed the issue quickly and gotten it resolved. Joey and team did a great job.

Great quick service. Came out on Sunday and got us fixed up in a jiffy.

James of McCullough Heating & AC was very professional and helpful in his advice on 3 repairs for my aging HVAC. I have used McCullough for check ups and repairs for several years and always appreciate their professionalism, timeliness, and responsiveness.

Always great and timely service!

I've recently moved to the Austin area and purchased a home. McCullough was recommended and I immediately signed up for there preventative maintenance package. Both times our same service tech came out and since he was familiar with our property he was able to get the job done quickly and he has so much knowledge! Thanks to Shelton and the entire team at McCullough!!!

I would love to share the incredible experience that we have had. Kyle was exceptionally phenomenal. We had a number of things that we didn’t understand why they were happening. He did thorough inspection work. He looked at everything very much. He then proceeded to provide us with an overview of what he saw was going on and his action plan to fix it. he came back and then fixed it after he got the parts and the other things that he needed. Kyle is the best!!!!

AC needed new board. No worries, McCullough is here on time and fast

James technician explained everything in language I could understand, he was patient and i formative. I can recommend him and your company. Charla Hathaway

I would highly recommend the McCullogh team for your HVAC needs. They have installed two systems for me. One of them was a complete overhaul including moving the attic unit to a better location and reconfiguring some ducts to improve air distribution. Everything about this crew was professional and quality. Good communication, explained everything well, the install was professional.

Excellent service, prompt and professional. Harry was outstanding

Had an A/C problem and called overnight to get appt. for next day. Service call fixed the problem and no charge for a simple drain clog that automatically shuts off the A/C. we've been satisfied McCullough customers for about 10 years now!

Love McCullough! Professional, friendly and on time! Also, they are “just nice” people!

I called at 8:15am because the system wasn’t cooling right. Within hours Nick was onsite and successfully determined the issue. Nick thoroughly explained the issue and ordered the part. The very next day he was back and didn’t leave until everything was checked and confirmed working correctly.

Kyle S was prompt, courteous, thorough, and efficient in identifying the problem and taking care of it - and, he left the area cleaner than when he found it. We appreciate being able to get same-day service calls with no problem. This is the second time McCullough was able to respond to us immediately. It's great to not have to wait very long!

Great communication when it comes to scheduling and arriving. Very professional employees. I do recommend learning about HVAC so you know what questions to ask.

Tech was respectful of my property and of me, wearing appropriate PPE and social distancing. He explained everything and followed up with a detailed report. No high pressure. I will certainly recommend them to others. Update: McCullough just installed an entirely new system for me. They arrived shortly after I called and brought a window unit for my bedroom to use until my system was in. Had done my research and Alex suggested exactly what my research indicated I needed. The installation was scheduled for the next morning, Saturday, and the installers followed safety protocols. So grateful for them going all out to help me. They were exceptional and I recommend them highly and in fact already have.

Junior was very helpful and solved our AC problem. Thank you

I love working with McCullough! They are so friendly, professional, prompt, and economical. They don’t try to upsell and shoot straight and are very cost-conscious.

Our AC was not cooling and I called McCullough using our prepaid unlimited diagnostic program The technician, Mitchell, promptly discovered what had failed (subsequently confirmed) , pointed out that costly $3,000 repair was not the best decision to make on a 14 year old 5 ton Carrrier unit. The salesman, Joe, promptly arrived, agreed with Mitchell, proposed a new Carrier replacement at a good discount. Installation went smoothly two days later and unit is working well. All debris was removed. Could not have been done better. I later learned price was very competitive and fair.

We were having some issues with our air conditioner and our thermostat and DeAndre from McCullough heating and air came out to help diagnose the problem. He was professional, polite, on-time and very patient in trying to figure out what was going on. We would definitely have DeAndre back in the future.

Alonzo was great in diagnosing my system. Very professional. Very helpful.

Nick Staggs helped with the HVAC maintenance, he was thorough and very knowledgeable. Thank You

I just had my furnace checked for the season. As a member of the maintenance club, it was complementary. I’m all set for winter now! The technician was on time and knowledgeable. No issues.

Rhey apotted the issue very quickly ans made the repair , iam 100 percent satisfied

Henry was fantastic!

The technician was extremely professional, a nice person, and explained answers to any questions I had.

Professional, courteous, punctual and knowledgeable. I’ve also experienced the same 5 star service from Troy, Jess, Nick , & Mark. Excellent business & superior product; love our Carrier systems.

Okay, not great not bad. Misunderstood request from office, service man polite.

Returned home after several days away and heard a strong vibration sound coming from the compressor. We called the 24 hour service around midnight and they were able to set up an appointment for the next morning. The technician showed up first thing discovered the source of the vibration fixed it, and also cleaned up the compressor. Very satisfied with this level of service

Excellent, courteous, professional, expert service.

Shawn did a great job getting our ductwork repaired and balanced and came back to make sure it was right after noticing we had too much air in certain rooms.

James was on time and efficient. He explained everything so I could understand it. I really appreciate McCullough and feel like I am in good hands! Thank you.

Frank was very professional and personable. He completed the service quickly with a fair price. I will be calling McCullough next time I need service.

My technician was very knowledgeable and did a great job, will definitely ask for him again .

Dereck was on time, pleasant, friendly, and efficient. He explained that all was well, and that he saw no problems for the foreseeable future. He also installed my new filter for me. I would highly recommend Dereck for his services!! He did an excellent job!!

Have had excellent communication and service from them since our new installations. Always polite and prompt service crew, too.

McCullough is a top shelf company. Their technician EJ Pittaway did an excellent job solving and repairing my A/C problems. I called on a Sunday, made an appointment for Monday and was fixed by that early afternoon.

On time, polite, and thorough. Highly recommend.

GILBERT Garcia and Mike installed our new HVAC system this week. They were prompt, courteous, extremely capable, and did a great job. Our a/c is definitely running quietly and more efficiently. We're glad we chose them for our needs. Highly recommend !

Love these guys. I've had them install a mini-split in the garage and most recently had them come out to clear out a clog in the drain from my main unit. Booking was super easy and they came out the next morning. Alonso, the tech, was awesome, not only did he clear it out, he was able to figure out design flaws in the original build and brainstormed ways to address the long term problem. Thank you for taking care of me, McCullough Team.

Recently got 2 Carrier variable hvac systems installed and extremely happy with McCullough heating & air conditioning. Their quote was very reasonable compared to others. Their installers and technicians are very knowledgeable and professional. Will definitely recommend them to others.

Amazing service !

Great and honest service!

My AC Unit was only 3 years old but ran into major issues where the cooling completely stopped. Luckily still had the parts warranty and Kyle from McCullough walked me through the entire issue with all my options especially with what was covered and what was out of pocket. They provided discounting options through maintenance plan and they repaired everything as quickly as they could! I really appreciate all the time Kyle put in to resolve my AC issues within a day after the initial inspection.

Desmond was great: kind, knowledgeable and efficient.

Great service and easy to work with. Very considerate of our time. Have used MCCullough for a few years and extremely happy with their service and professionalism.

Kyle Stirling did a great job. I had a pretty unique issue with my HVAC system, and Kyle spent the whole morning trouble shooting. I was very satisfied with his diagnosis and feedback. Thanks Kyle!

James patiently explained the various options we had to get out a/c back up and running. He helped us make the best decision to resolve our problem. I strongly recommend him to anyone finding themselves in the same position.

Junior was super nice and answered all my questions! Scheduling was easy. Came out same day and saved us!! We've used them since 2019 and will keep on!!

Very Friendly, efficient and easy to talk to. Answered any questions we had to ask. Very informative.

Customer for past 2 years. Excellent prompt service so far.

EJ and his team did a great job today. They helped me understand my a/c and heating system and were able to get me set up with a maintenance contract at the same time. McCullough is also offering a new service to help avoid drain clogging. I have lived the clogged drain nightmare and was excited to hear of this new service. Thanks guys- job well done!

Second time Mitchell has been out. Great tech. Friendly, clear, considerate.

Amazing company! Great service in a timely manner.

James was very cordial, on time and very helpful to explain things.

Great service from James and the team at McCullough on our ac vents. Highly recommend them.

I give Joel Galvan a 10 out of 10 for servicing my AC unit.

Desmond was fast efficient, and very personable. Explained every step of the fix on our AC unit. Highly satisfied with his work.

EJ was very professional and extremely knowledgeable and helpful. There was no "up selling", just the facts and recommendations. We'll see you guys again in about 6 months. Thank you.

Came at time scheduled and employees were kind and professional and answered all questions asked. They did installation and cleaned up afterwards. Best service ever. I would highly recommend this McCullough to anyone.

Junior did an excellent job repairing a leak in my AC overflow pipe. He worked diligently until it was completed, explaining everything he was doing. I would highly recommend him and McCullough Heating & Air!

EJ is punctual, polite and showed expertise. He quickly diagnose our issues of not cooling the second floor to leaky evaporator coil. He answered all my questions regarding the issues. Thanks for your hard work.

Very knowledgeable, shared with me how to save money. On time and diligent

We had a great experience with Junior de Jesus who was excellent at diagnosing and promptly fixing our HVAC system. Thank you Junior!

Great customer service. I got a great explanation of what he was doing!

EJ was very knowledgeable and gave me some great advice on my HVAC system. Highly recommend!

Shawn was awesome. Explained what was needed to fix the problem and implemented the fix with top quality craftsmanship.

Scheduled a second opinion visit and McCullough clarified with me that there is a problem but gave many options for diagnosis and possible repair. I felt like an informed consumer and will move forward with confidence. Follow up!! Joel came and diagnosed (after many attempts) a small leak in our system. We together came up with a plan to monitor the system after stopping the leak. I am going to follow up with a maintenance plan with McCullough as a company I can trust to have our best interest at heart and not just profit.

Great service as always!

Desmond was thorough and knowledgeable. Got my system up and running in no time!

Technician EJ was extremely professional and knowledgeable. I would recommend this company any day. Solved all my HVAC issues

Nick was kind, punctual, and thorough replacing our hvac motor.

Dereck and nick just installed our coil, and I am beyond happy with my service and experience. I am so happy I went with McCullough for my ac troubles and repairs. I’ll be using them anytime in the future!

McCullough was great. My AC went out while it was 97 out and they were able to come same day. Alvin, my tech, was awesome! He explained the issue and that the part they needed had to be ordered, but got it quickly and was able to come back the next morning to get it installed. I'll definitely call them again and look into hiring them for regular services.

We had our water drain line clogged again and tripping the AC off. The technician , Mitchell, was very thorough to ensure that the issue was fixed. We appreciate his detail oriented approach to get our AC running.

Currently having a dispute on a repair with a home warranty company, I called McCullogh for a 2nd opinion. They sent Joey who arrived promptly the next day, was professional, knowledgeable, and explained everything in detail. He found the problem (refrigerant leak), wrote an estimate and got it over to me within a little over an hour. It took over a week (a very hot week) for the technicians employed by the warranty company to do the same. When it's over 90 degrees in your home office, it's very much appreciated to find this kind of response from a local company.

Thank you DeAndre for your great customer service, and getting the AC to work and cool our house again. . We appreciate you very much.

Hands down...one of the best service providers we've ever worked with! Chris provided estimates for the work we needed and walked us through all the details. What a great communicator! The crew of men who installed our new unit were diligent, professional, and courteous. What impressed us most was that McCullough Heating and Air provided a quality control visit two weeks after our installation. Jimmy was great to work with and was so very patient and respectful when talking us through our new unit and thermostat usage. What a great and painless experience for us! Thank you everyone at McCullough! Neal and Karen

We had to replace our entire a/c unit and I was worried about the cost. The McCullough team helped us get the financing we needed and from there it was on! Shout out to McCullough Heating & Air Conditioning for all of the patience, support, and literally doing everything and I mean everything, down to the rebates and signing us up for credits through our electric company. Not to mention the delicious Tiff’s Treats delivered to our home! 😋 I would highly recommend them.

Mitchell did a great job fixing the pump on my AC unit

EJ was on time, fast, efficient, knowledgeable, and friendly. Highly recommended.. Gary

Prompt service with a smile!

McCullough Heating and Air is a well run local company with a long standing reputation which continues to be well earned. It is staffed with pleasant people to receive your call, and polite and well trained/skilled tech arrives the same day and solves your problem. Service charges are fair and reasonable - unlike many others.

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.

Nick Staggs came over, diagnosed the problem and took care of it within an hour and a half. I'll definitely call up McCullough again!

Henry, technician, was great. And super polite. 😁

Very honest and timely support. Would highly recommend their service. I felt that their services are priced right.

Best of the best! While traveling in Singapore we found out our AC was down, a phone call and a couple hours later they had things sorted!

Junior diagnosed our problem quickly. He was very informative and professional.

Provided same day service to fix. Technician Henry very knowledgeable on fixing AC. He was courteous and explained what he was doing. Great job!!

EJ showed up promptly and recharged my household ac system. He was professional and explained everything he was doing. Thanks again EJ.

Very happy with quick service first thing in the morning after booked the night before. Alvin was so efficient, professional and communicative. He fixed my problem and is a such a nice guy as well! This was my first time using McCullough and I will definitely be calling them for future needs.

I called McCullough first thing in the morning about an AC issue. Junior De Jesus was out in only 4 hours. He was extremely professional, knowledgeable, and quickly fixed the issue. McCullough is the only service we use these days. Thanks, Junior and McCullough!

They installed our new AC system back in February, they were cost effective and had a great warranty. We’ve had a few tweaks needed since but they’ve come out timely, and really have gone above and beyond trying to make it all right and never an unexpected bill.

Joey was great, he clearly explained the problem and solution very clearly. He was to fix our AC in a timely manner, and now our AC is working perfectly!

Dereck was very helpful, kind, and professional. Diagnosed the problem and got it fixed. Thank you Dereck.

Have good professional techs. Had Alvin come out and was very impressed by work ethic’s.

DeAndre was professional and communicated exactly what was wrong with my AC unit, fixing it the same day! I will definitely use McCullough again and would recommend them 100 percent! Thank you, DeAndre!

We had to have the Heating/Air and Duct work replaced after many years. After several bids ,we decided on McCullough. Troy,our service advisor,made a thorough and reasonable bid with a City rebate.The work was completed in a timely and professional manner.Hard workers. Some adjustments and improvements were made during the process..The rebate was approved and troy followed up on minor finish-up. AC working great. 5 STARS John Y

Fantastic service. The tech that showed up (Joey), was on time, professional, and personable. He fixed our problem and presented options concerning our system. He was very knowledgeable and shared that knowledge with me. Great tech! Install team arrived on Friday for replacement of A coil in unit in the attic. Ricardo and Adrian did great job. Another problem arose with compressor. It had gone out. Joey came back and replaced the outside unit, making sure my wife and I had cool air for the weekend. He stayed until he was sure everything was operating correctly. We were pleased with the great service! 9/18, Joey came back to check levels from work done last week and recommend added fixes to get the system to peak performance. He provided estimate of costs and what these improvements would actually do. As always, it was a pleasure dealing with him.

My ac stopped working on a weekend. They showed up within 2 hours and got that fixed in 30mins. I found the technician knowledgeable and helped me understand the ac system for routine maintenance and simple diagnostics. Definitely recommend them

Technician was prompt and courteous. He provided the annual check up and proper flushing instructions.

Desmond was terrific - he clearly knows a ton about air conditioning units and was fast and efficient.

Wonderful service! Repair was affordable and fast, as all of my previous visits!

Mitchell Reaves and the McCullough Team made quick and efficient work of a critical problem we were having with one of our air units. Response time from initial call to hands-on addressing and solving the problem was impressive and appreciated!

Excellent service, knowledgeable, friendly… Would absolutely recommend to anyone.

AC froze on the wkend and within hrs of a cold call Nick S was out. The next day EJ came to finish the job and now we have a path forward. Both were knowledgeable, friendly, communicative, and professional. I plan to use McCullough for all AC needs, maintenance and unplanned, moving forward.

Awesome service! Fast, thorough, and good eye on the big picture!

They arrived on the same day that I called. My AC wouldn’t even turn on! It turned out to be something small and my AC was up and running in about 20 minutes later. Thank you, McCullough!

$325 to clean the vents and fix the thermostat wiring seems like price gouging to me

Great service at a fair and reasonable price. So nice to have HVAC service that correctly assesses the problem, clearly communicates to the customer, and lays out fairly priced options.

Junior was fantastic, super knowledgeable, helpful, and a true professional. Junior, and all the people at McCullough, are why we opted for the McCullough Membership, and only use them for all our heating and cooling needs. Couldn’t be happier with their service and Technicians. -David in West Austin

We were so fortunate to have Nick Staggs working on our A/C system. We was truly dedicated to resolving our issue. He never once didn’t deliver on what he said, and he was absolutely honest through the whole process. He has the real skill and training that it takes to get an A/C system back in operation. Thank you McCullough for having techs like Nick. The fact that McCullough Heating and Air can source and maintain such skilled techs makes them the gold standard in the industry.

Reliable service and friendly technicians

McCullough is the best! This was just a maintenance call, but our tech was awesome and did a great job! I would recommend them to anyone!

Outstanding Costumer Service

Very knowledgeable friendly service.

The guys Rich and Chris worked on the new outlet for AC and heat. They kept me informed and we discussed options for where the outlet would go. It has been good experience.

Fast, great service with friendly people

Frank is professional, and explained the workings of the system to me so I can be a better custodian of the HVAC system.

I've had McCullough for several years to maintain my AC and heat unit. They send me a reminder and I pay for the maintenance monthly which makes budgeting easy. EJ Pittaway phoned 30 min prior to arrival and showed up on time. My AC had quit working and EJ had it fixed in no time. He was very professional and thoroughly explained the problem. I would highly recommend this locally owned business.

This was our first time using McCullough, and have found them to be prompt, polite, and easy to work with. Our 27 year old system finally wore out! Troy was very knowledgeable in presenting our options. Gilbert and Michael did our install and we're both terrific. Both were very professional and highly competent. Importantly, when they unboxed the condenser unit, they were suspicious of how it was working--- long story short, it managed to keep us cool over the hot weekend until a new, undamaged one was installed on Monday. Kudos to them and the company for honesty. Thanks again to Gilbert and Michael...not only smart professionals, but all around nice guys.
