Great service from Dylan at McCullough Heating and AC. They were able to quickly schedule something for me. Dylan quickly diagnosed the problem and cleared a deeply clogged drainage hose. Amiable and professional service. Would recommend.

Great job fixing my air conditioner. Vladimir was a super technician! Being a Comfort Club member sure paid off! Fast service at a great price.

Dillon Revells is the BEST and I would give six (6) stars if I could! My drain line was clogged and it snapped at the attic unit. The threads to the fitting snapped in the attic unit. The sensor turned the system off and I needed help. McCullough sent Dillon to help me get the air going. The problem looked really bad. Dillon explained the situation and the possible costs to repair. It was a difficult looking situation to both he and I. Then, Dillon said he was going to try something radical. He went to his truck, got the tools he needed, and in less than 10 minutes was able to extract the broken threads and fix my broken line issue at minimal cost. Dillon then went outside and dug up my buried drain line and cleared it of the roots that clogged it. My weekend problem was fixed by Dillon in less than a half hour. If you want the best, please ask for Dillon. I am completely satisfied with the knowledge, work, workmanship, and professionalism of Dillon. McCullough is my choice service company and Dillon my choice technician.

Technician Naser Berenji worked diligently to fix a major problem with my A/C system which cause the Ecobee thermostat to reboot repeatedly, thus not cooling my house enough. After several attempts, using various methods, he finally cleared the water drain line which had been clogging and causing the problem. I was very pleased with his work.

Thomas did a great job on our mini-split. He knew what we needed, brought the part, installed it, and made another change that we suggested to prevent water releases from the unit. We are very happy with his work and his professionalism.

The most impressive thing about McCullough was the knowledge and professionalism of its technicians. The ease of customer service/scheduling department made the whole experience very easy as well. Not the cheapest option but for a reason, they deliver value in every interaction: phone, virtual, and in person. I was also in between travel for work and on a tight schedule. I had two technicians come out on separate occasions for the same issue, 1 to run a diagnostic and the other to conduct a leak detection and then replace the Evaporator Coil. I also had a sales rep come out to give me some options on replacing the entire unit. The sales rep was also technical and knew his stuff, he was very helpful in guiding me through understanding my options. At the end, the service manager not just replaced my evap coil for a reasonable price, but the technician helped me balance the outside unit, replaced the fan motor, and conducted other diagnostics included as part of the service. 5 stars all around.

Dillon was friendly and competent. He got my AC unit cooling again.

Buying a new HVAC unit is never fun, but working with McCullough made it way less stressful than I could’ve ever expected. From the first diagnostic tech that came out ( I can’t remember his name 🙁 ) to the install team and especially the project manager Evan, everyone was super kind, professional, and patient with all my questions. Evan helped me find the right unit without pushing anything on me, and made sure it was something that worked for my home and my budget. The install went smoothly, and even after everything was done, the McCullough team followed up just to make sure everything was running smoothly and I was satisfied with my new unit. What stood out to me the most was the level of care and the personal touch the McCullough team provided. You don’t get it everywhere. If you’re dealing with this Texas heat and need a tune up or a new system, call McCullough Heating & Air. Seriously. I couldn’t recommend them more!

McCullough and their technicians have been great to work with. They offered me options for repairing my system, had competitive quotes and were professional throughout the process.

Vladimir identified and solved the problem quickly and was very nice and informative.

I am a regular McCullough customer and have a maintenance service contract.with them, I like the work they have done and am comfortable doing business with them.

Kyle 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!

Thanks McCullough for a flawless smooth service. Alex S. led the way with helping pick out the best AC unit for my needs- the GE Connect variable speed - it is quiet, steady temp control and less humid in my house now. The team that put it all together and replaced duct work were also very professional and kind--thanks so much to Jordan, Ivan, Mark and Christian. Yall were awesome and worked so hard in hot temperatures. Lastly Jimmy came by 4-5 days later to do a quality check. Thanks, Jimmy. I will always call McCullough for any ac or heating needs i have.

Jaiden the techican was very through, respectful, courteous and clean after he was finished. however, communication from either he or the office or both could be improved, technician didn't arrive until 5:30.

Always happy with McCollough’s - HVAC technicians, especially Vlad Savinov, are well-trained, good communicators, and personable.

Fast and knowledgeable, Josh did a great job at explaining the issue and got it fixed quick.

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.

Henry is the best technician I ever met. He replaced our A/C compressor unit recently at my house. He did his best for making A/C works perfect without any problems. He even came back later evening for the unit to be completely dry. Now A/C works perfectly and even quieter and cooler. I am so happy with his work. Thank you Henry!

Mikael was the best tech, I've ever had. Hands down the best.

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.

We had a new air conditioning system installed. They were highly professional and did an excellent job. Financing was easy and they were polite and neat. Highly recommend.

Guillermo was our service tech today. He has been here before and this visit like his other visits have been exceptional. Friendly, professional and able to answer my questions completely. Highly recommend the team from McCullough.

Sean identified my problem immediately—a backed up drain pipe. He blew it out, poured in a cup of vinegar and advised me to dig out around the outside pipe and fill it with some pebbles or rocks. My thermostat is working again and I have a plan going forward. Thanks, Sean!

Kyle 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!

We replaced our HVAC with a system we purchased from McCullough Heating and Air. The crew worked hard to install everything in one day. They did a great job. Their manager followed up the next day and signed off on the system. Very professional crew, I highly recommend them to any one considering replacing or repairing your HVAC.

I'm not sure if there is such thing as HVAC intuition but Sean came and diagnosed a problem that I had spent 3000 dollars on so far with other companies. I never knew my house could be cool all day instead of constantly fluctuating. My unit was under warranty so Sean was able to get the parts free and installed things quickly. Great value and they have earned my business from now on.

Scheduling online doesn’t have an option for ac tune up so when the tech came out he was a little perplexed that my AC worked. He said that tune up would take a long time and have to be rescheduled another time but he gladly took $80 to say my AC doesn’t need Freon after poking holes in my ductwork. He was friendly and informative though. Not $80 friendly but maybe $10 for gas friendly.

Fantastic service, professional and efficient. Their technician, Makaela, was quick to diagnose and repair my AC unit. I received all cost estimates before work started and was clear on additional work that could be done without making me feel pressured to have it done right away. I'm very satisfied with their work!

Great service! Really nice and honest people to work with.

This is now the third time I've used McCullough with a variety of problems for our aged AC system. This time the problem was bad enough we had to replace the entire system so we had the chance to interact with both the repair and installation sides of the company. Needless to say I was extremely satisfied with their service -- Our install team (Richard and Francisco) were absolutely amazing and worked non-stop all day in 90 degree heat to get us up and running. At this point I wouldn't trust anyone else with what I think is the most important utility here in Texas.

Only changed filter, but Eric came in with smile , on-time, and very personable with great attitude. Great Service Guy!

Dillon came out to check an issue. He was efficient and courteous. McCullough management was quick to respond to my problem without any hassle! Very appreciated. A shout out to Alex Stevens for coming to my rescue. What a great team!

It did not start off well, I waited from 8-5pm only to find the service man wasn't coming. I was rescheduled for the next day. They did apologize. And the service man came before noon. The service was good.

McCullough installed our hvac system several years ago, and we’ve had them come out a number of times to do maintenance checks and minor work. Very pleased with their work and advising us on taking care of our system

They responded that very same day when I called them and needed there service awesome!!

Great service from Dillon! Consistently happy with McCullough.

Dillon was awesome! He did a great job, explained all work in detail and answered every question I had.

Kyle was very helpful and informative.

Great and honest service!

Knowledgeable, friendly, courteous and competent.

McCullough is the gold standard as far as I am concerned. Tom Ischy was great, explained everything without "splaining" down to me. Just the facts Ma'am. From what I saw he works smart and efficiently, nice qualities in a Tech. If you need a new HVAC or repairs and service you can't beat McCullough! Honest, dependable, honor the warranty and everyone is so nice. My most recent McCullough experience: Friday13 sure lived up to its name for us. HVAC went out at about 11:30AM. I called McCullough as soon as I found the alerts in my email (maybe an hour later). Dispatch said they would try to have someone out by 5PM, but it was a busy day and the appointment was pushed back to 5P-8P. Tom Ischy showed up around 6PM and had the situation diagnosed by 6:20P. He explained the situation and was gone by 6:30PM. Unfortunately a part had shorted and fried, so it and its smart board would have to be ordered. I realized that since it was after hours the order would not be handled until Monday. The part arrived at my house on Tuesday. I called to schedule the repair. They were all set, waiting to hear from me and squeezed me into the schedule. Tom came out again around 6:20P, made the repair, reset everything and was gone, oh, maybe an hour or so later. We all did the happy dance and began closing windows and turning off fans as the house began to cool down. BTW the Comfort Club is a nice option.Yeah, it has a yearly or monthly charge, but from my experience is definitely worth it. Yay McCullough!

Fast, great service with friendly people

Prompt, polite, professional.

Guillermo, James, and the whole team at McCullough have been really great to work with! Truly. These are caring men and women who value helping others stay safe and healthy even with their air and systems in their homes. We are so grateful for their help and would recommend them to anyone looking for a high quality company and employees to work with. Thank you McCullough team!!! Our family has been taken care of so well and we are safe in our homes thanks to you all.

Excellent service from these guys.Eric was very knowledgeable, professional and respectful. I would recommend them to anyone for all heating and AC needs.

Henry and Nasser did the necessary repairs quickly and then spent a little time with me answering questions. Over the past 8 years my experience with this company has been uniformly positive.

Kyle Sterling just completed annual maintenance on the two carrier units - thankful for his casual competence. ______ One of two recently installed Carrier heat pumps had a leak on a factory weld at the condenser. Desmond Lopez was the tech that diagnosed, repaired, and tested our system. He is a capable and courteous young man that is a valuable asset to your company. _______ Sheldon quickly diagnosed and repaired a leak under the air handler caused by a recently-installed PVC drain that was glued. water damage to a wood floor in an adjacent room alerted us the problem. Perhaps we should have ‘called a plumber’! Thanks ______ Problems were resolved, professionally — Thank you. 6 months after installation of the 2-speed Carrier heat pumps, the summer, fall, and winter comfort factor is far better than our previous units - thankful. Annual maintenance - needed noise abatement between air handler & coil on one unit - work to be scheduled. noise abatement between air handler & coil on one unit was completed by a very competent service tech - James _______ Deandre performed scheduled maintenance on two units - replacing a capacitor on one (under warranty) and diagnosed a vibrating noise inside as a loose vent. Well done. Thank you.

Sean very professional and knowledgeable and excellent work habits. Glad to have him working on our system. If need work in the future recommend him highly.

We use McCullough for our annual inspections for heating & cooling. We were lucky enough to have Brian as our tech for this year's cooling checkup. After mentioning the air conditioning drain (which runs through the master bath sink) needed a bit too much Draino this spring, he cleared all the backup which turned out to be more clogging than expected. It's that extra step that keeps us coming back. Thanks, Brian.

Junior De Jesus was the best McCullough service person we’ve had over the past few years. He was kind, courteous and one could see his experience, offering very helpful info. He also helped us program our EcoBee thermostats to our desired specs, and was kind enough to change out our whole house filters and carry away the used ones…. McCullough and Jesus are awesome!! Highly recommended!

Guillermo was pleasant, worked efficiently, put items back that I had cleared so he could get to units. mccullough has been my go-,to for hvav needs. Guillermo is an example of why

Great service. I believe he solved teh issues. Very Friendly.

Thomas came after hours and fixed our situation the same day we called for a fix. Recommend this company 100 percent. We had a dead thermostat that he fixed after my family came in town. Live savers!

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

Very knowledgeable, great customer service!

Sean very professional and knowledgeable and excellent work habits. Glad to have him working on our system. If need work in the future recommend him highly.

Good experience but not happy with labor charge.changing capacitor part and labor very high. Adding coolant charge ok. I will not call them next time.

Have always had a great experience with McCullough Heating and Air. I highly recommend them! The Technician Thomas was friendly, professional, informative and thorough.

McCullough turned out to be a pleasant surprise after having used both small and large HVAC companies in the past. The service tech, Sean was on time, experienced and professional. He worked hard at diagnosing a complicated (not easy to diagnose) problem with my AC unit. He answered my questions during the whole process and gave me an estimate prior to doing the repairs. I liked the way he was supported by other techs while he worked to fix the problem. I would recommend McCullough for your HVAC problems because their service felt like a small company but with a large company’s expertise.

Josh quickly figured out the problem and got our ac up and running. He also took the time to explain the repair options in detail which was very helpful. I will definitely use Josh / McCullough again!

We had a great experience with McCullough's HVAC service and Eric was very thorough and professional.

Thomas Ischy of McCullough Heating & Air Conditioning, was my knight in shining Armor. It was 8:30pm & he resolved my many issues with my A/C unit. Not only did he explain everything in terms, I could understand, he made suggestions to improve the efficiency of my unit. He was friendly, efficient & on time. Thomas is truly appreciated. I highly recommend their services. McCullough hires highly trained, knowledgeable & trust worthy individuals.

DeAndre did a fantastic job on our fan cleanup on our HVAC system. He was meticulous about his work and a very polite technician. We’d be happy to have him as our technician any time.

great company. we have had very attentive service over the last several years.

My ac issues was resolved promptly.

Replacing my over 20 year old HVAC system was something I had dreaded since I bought my place. After the system finally failed, my home warranty company set me up with a hack company with a 1.7 star rating on Google, then hung me out to dry. I went looking for the most reputable company in Austin and found McCullough. Evan was our project manager and he was wonderful to work with. He and the team answered all of my questions, and sold me a reasonably priced system that wasn’t too much for the needs of my small, older place. Jordan was awesome during the install, explaining everything as they were doing it. The whole crew kept my house clean, and they even sent someone out to do QC and teach me about the system. If you want an honest company who shows up when they say they will and actually cares about customers who are living without A/C in the summer heat, look no further.

Clean the coils and drains for about 350... The dude was very helpful and answered all my question and give great input back... Thank you...

Henry was very knowledgeable, professional and thorough. The price was very fair and the work was fast!

Josh came out on a Sunday and took care of our thermostat problem. Very professional and efficient. We have used McCoullough a few times now and are grateful for their services.

The service I received from the team at McCullough Heating & Air to replace my HVAC equipment was exceptional from start to finish. From my project manager Evan who listened to my concerns and advised me on an appropriate system within my price range to my installers Richard and Francisco who took great care with my home and showed pride in their workmanship while installing the new unit and the support staff who assisted throughout. I'm glad that I chose McCullough.

The technician arrived on a Saturday evening and located the problem with our furnace! He was polite and knowledgeable!

After meeting with Joel Galvin today, I have a much clearer understanding of the cause and potential consequences of the HVAC condensate drain blockage I experienced recently. Joel had nothing to sell, yet he took the time to walk me through what the next steps could involve, should I choose to pursue remediation work. His expertise was clear, but he explained everything in a way that was both understandable and relatable, leaving me feeling reassured rather than overwhelmed. His commitment to service was evident throughout the visit. McCullough is fortunate to have him on their team. Thank you, Joel!

McCulloch has taken care of us for at least eight years. They put in this new unit when the old one went bad. That was also a holiday weekend, and they put in temporary window units to get us through. Also a remarkably hot summer. They came out today, to check on an odd noise. They discovered nothing really was wrong, but I am very relieved at having professionals support our system. Especially in this age of global warming.

Excellent service and honest. Would recommend to anyone.

Jaiden Mendez did an excellent and thorough job in my system check. He reworked some AC pipes to work more efficiently. He was prompt and polite. I always recommend McCullough to friends and family. Thank you.

Dillon did a great job communicating to my landlord who lives out of state. The repairs were scheduled in a timely manner. Now we will stay cool this summer!

Very helpful and knowledgeable

Shawn came out on the weekend and went above and beyond to service our ac on a very hot day. He seemed highly knowledgeable, and ran through a list of potential issues that he was going to investigate, found the problem, and then provided a thorough explanation of the issue and the fix. We highly recommend!

I’ve been using this company for years. Timely helpful and excellent service. Often the same tech year over year so know my systems. Highly recommended

Henry and Naser were both very helpful and friendly, I would request them next time!

Called on a Friday night and they were out on Saturday. Very knowledgeable and found the problem to our a/c leak issue that others missed.

A long-time Austin company that provides top notch value and service. The technician, Henry was the epitome of professionalism and just a great guy.

Great service from Alvin and McCullough!

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

Henry found what was wrong with my air conditioner, got it up and running, and explained in clear terms what was needed in order for the unit not to have recurrent problems. I was happy to schedule the repairs he suggested.

Had an emergency AC outage - aka summer in Austin - and they were there same day to fix on a Saturday . Very knowledgeable and fair priced

Customer for past 4 years. Excellent prompt service so far.

Josh quickly diagnosed the problem and the repair was completed as promised. He provided friendly, polite and expert service.

Jaiden the techican was very through, respectful, courteous and clean after he was finished. however, communication from either he or the office or both could be improved, technician didn't arrive until 5:30.

This is a superb company with stellar customer service. After the hail and rain storm last week, we needed help with a problem with the AC drain. McCullough listened well, and had a reasonable solution . Ivan and Jordan fixed the drain efficiently and we're on time and professional. We highly recommend this company for their expertise and solid service. Rick Gerber

very pleased with technician......

Kyle came to look at our HVAC on a Sunday during a holiday weekend. He was diligent, professional and very clear with his communication. I would recommend McCullough and Kyle.

Had another great check up by McCullough. Sean was efficient, thorough and helpful explaining what I need in the near futte.

Eric is polite, efficient and professional. Great service. 5 stars for that. I only wish McCullough had shorter arrival windows.

Always professional and reliable

Polite, fast and professional.

I use them for doing A/C inspections. They are knowledgeable and friendly. Really appreciated the work by Guillermo Mata looking for future issues that could lower the efficiency of my system and cause it to fail early.

Jaiden Mendez, Did a wonderful inspection on my AC unit very empress with his professionalism, he took his time and inspected everything that had to be inspected Would really like to have him be the gentleman that would come over and do my inspections twice a year. This young man takes pride in his work excellent worth of ethics.

Great and friendly service again by Shawn and the McCollough team! Only docked them one star because of a mixup with my phone number getting linked to the wrong service call, so that might’ve delayed things a little. But otherwise great.

Eric Suarez came over for a service call. He found the issue very quickly and worked efficiently to fix it. He gave clear explanations and tips to improve the AC experience. Very professional and personable. Excellent work!

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 company. we have had very attentive service over the last several years.

Henry was Kind, patient. Polite, expert! Honest! Thank you.

Very personable and knowledgeable individual. Expert in the field. Dillan was very meticulous and kept us informed along the way.

Who you gonna call when water is dripping out of your HVAC closet? I’m so glad I have a McCullough service contract, because their technician, Josh, addressed the issue before the end of the day and with such positive energy… at no charge! All is well that ends well.

Eric Suarez was very knowledgeable and quick. He was able to do a full maintenance check of our year old system and make sure it remains in top shape. Thank you Eric and McCullough for providing great service.

Was looking for a new HVAC system, getting quotes from multiple companies but John really sold me on this company. Affordable and fairly priced. Great service very Knowledgeable and patient with our decision making. Him and his team were punctual, professional and very communicative during the entire installation process. He answered all questions before, during and after installation. Quick and easy to work with. We are very pleased with our new system in the Texas heat. Would highly recommend to all my friends and family.

Josh Henderson quickly diagnosed and solved the problem. Also, the McCullough scheduling staff is outstanding. I appreciate the excellent service. Thank you!

Excellent service and very friendly and professional staff. Very happy with the 2 stage AC they installed and it works great. Staff is very knowledgeable and informative.

Great work, as always. Good customer service and quick response.

Kyle is very knowledgeable and courteous. Job was completed in no time. Thanks

McCullough technicians did a outstanding job in quality as well as in service.. Very professional.

Great communication and advice. He followed through.

Brian was great. Punctual and super thorough! Very happy! Thanks!

The technician was friendly and answered all of my questions. It was a great experience. We will use McCullough A and C again.

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. Henry came by to perform spring service on Thursday 5/1/25. Very courteous and thorough. He advised of issues with A/C system, and made arrangements to return to install another intake and clean motor. Very good technician, listed all performance checks and was a pleasure to deal with. 5/8/25 Henry & Dylan returned to perform work. They were efficient, on time, performed the job in an excellent manner. Great job!

Thomas Ischy provided fast and efficient service. He did a great job with the cooling maintenance.

Knowledgeable techs who are transparent on issues and pricing and willing to work with you.

These guys were professional, nice and honest. They gave me their honest opinion of what i needed for to get my AC and ductwork running by I will be relying on McCullough for my next AC unit and ductwork replacement.

Kyle came to look at our HVAC on a Sunday during a holiday weekend. He was diligent, professional and very clear with his communication. I would recommend McCullough and Kyle.

Great efficient service.

Very helpful and knowledgeable

Great work! Henry was amazing and answered all my questions.

The service was good but the price for the job done was overpriced.

McCullough Heating and Air has long been my “go to” for HVAC. My 14 year old system was not cooling properly. They came out quickly and diagnosed the problem. Dillon, the service representative was great. Showed me the issue, explained everything in detail and answered all my questions. Dillon was personable, thorough and knowledgeable. I’m still very pleased with McCullough and I highly recommend them for all your HVAC needs.

Josh Henderson did an outstanding job repairing my air conditioner. He showed up on time, and absolute pro And got it up and running in record time. I’ve used McCullough for a couple years. And they’ve always been great with competitive prices. Highly recommended.

This company is so dependable and easy to work with. They don't push you to purchase services or equipment you don't need. Technicians are polite and helpful.

McCullough technicians did a outstanding job in quality as well as in service.. Very professional.

Fast, great service with friendly people

I had an emergency and called at 6 am. Dillon Rebels showed up, diagnosed the problem and the fix. He explained what happened and how the fix will work. Our ac was. Back up in 1 hr

Kyle identified and solved the problem quickly and was very nice and informative.

Dillon was thorough and explained all the tasks he performed. Well done!

Very professional, nice compassionate technician.

Very personable and knowledgeable individual. Expert in the field.

Service was great. Kyle quickly found the issue (clogged valve) with my AC (after someone from a different company suggested I’d need to replace my whole system). He took the time to explain the problem and answered all my questions. AC’s working great now, highly recommend!

Guillermo arrived in perfect timing to save the day from no AC! He was professional, knowledgeable, courteous, and did excellent work! I appreciate him explaining the work and answering my questions. From now on McCullough Air Conditioning will be taking care of all my AC needs. Let this excellent company take care of yours. You will not be disappointed!

Ac went out and they were quite prompt in all their responses.

Very quick and courteous

Guillermo was timely, communicative, very respectful of the house, and efficient. By far the best experience we’ve had with an AC repair company.

McCullough technicians did a outstanding job in quality as well as in service.. Very professional.

They perform Fantastic work. McCullough is the hvac installation, service and repair team in austin you can trust. The people from the office personnel, to customer facing serviceman , to sales force, to the company involment in austin area is all first class. Better than their white glove treatment is their focus on their customer needs. McCullough customer relations makes for a home relationship where your hvac is in good hands. McCullough for the full life of your hvac system. Its folks like mitchell reeves in service and in alex stevens in customer supprt and sales a great company.

We started using McCullough for our HVAC needs after another company installed our heat pump and made many mistakes. McCullough fixed the problems and has consistently given us superior service at our seasonal checkups. James, Brian, Alvin, Dereck and all of the technicians we have dealt with have been knowledgeable, efficient, and a delight to work with. We will never use anyone else for our HVAC needs.

Great experience. Prompt response nice people Joey and Josh were awesome!

Dillon did a great job diagnosing the issue with my unit and is getting the repair scheduled! Thanks!

Installed new HVAC system. Professional and knowledgeable workers. System working great.

Just had a new HVAC system installed by McCullough HVAC. Detailed presentation, questions answered thoroughly, my special request accommodated ( thanks Ivan) . Installers —prompt, worked straight thru 9 hrs. Very tidy....QC fella came to review All work—Could NOT ask for more. Highest praise for a great team…kv

Josh was terrific! On time, thorough and professional. Been with McCullough 15+ years.

We had a problem with our AC that wasn’t easily solved. Our technician, Joey, was friendly, polite, and patiently answered our many questions and did solve and fix the problem. I’ll definitely request him the next time we need anything.

Prompt efficient service. Friendly knowledgeable service technicians.

Very professional, very nice. Reassuring.

Thanks to Heidi(sales) and Sade,Derrick,Jesse,Angel and Vinny, we are ready for what is shaping up to be a very hot summer!

So profesional will recommend to anyone . Thank you so much for saving the day .🙂

Google won't let me leave a new review, so I am editing my old one for 5/15/2025. This is our third experience with McCullough and the service and quality is still five-star! Kyle came out to investigate why our AC was lagging in the heat and came back today to solve the problem. He was friendly, knowledgeable and experienced, and our house already feels cooler even though he only left 10 minutes ago! Once again I would absolutely recommend McCullough.

I am very impressed with this company and Im not easily impressed. They are professional, knowledgeable and respectful. I have used them on more than one occasion and I am always impressed with their expertise and efficiency. Once again, McCullough came to my rescue with professionalism, expert advice and repair to my A/C. Henry Harris was delightful and highly skilled. I’m so happy I became a regular customer 😃

McCullough Heating & Air got to us quick when our upstairs AC wasn't cooling - of course this happened on the hottest day in May. Shawn was on-time, professional, and got our system cooling again at a fair price. He diagnosed the problem(s) and gave us several options to consider. Fair company and responsive service. Would use then again and recommend them to others.

Kyle came out to do our annual service on the AC unit. He is incredibly nice and friendly. He went above and beyond what was needed and was a blast to chat with. McCullough continues to impress with the people they hire. Very happy customer.

Recently, McCullough Heating and Air Conditioning perfomed an annual preventive maintenance visit. The HVAC Technician, Brian Van Pelt, was highly knowledgeable in the workings of our Carrier system. He arrived on time and had all necessary equipment with him. He checked the air handling unit in the attc area and the compressor unit outside. He was careful to leave everything clean and neat when done. Brian also replaced the MERV 8 4"x16"x25" filter which I provided. He took the old filter to the shop for disposal whch was much appreciated. Brian sent me a full report on the condtion of the system which s ready for a hot Austin summer. I have high confidence in the capability of McCullough and its people. For that reason, I am a member of their annual service plan.

We have used McCullough Heating and Air for over the last decade and would never change. All of our technicians have superior knowledge and have kept our system in top working order. Would highly recommend this company for service!

Very responsive on service timing and very efficient and professional when they arrive. All of our experiences have been rock solid

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!

great company. we have had very attentive service over the last several years.

Prompt, professional answered all My questions. Excellent experience.

McCullough is a fantastic company. I have been exclusively using them for 20 years and every representative they have sent out has been top notch, competent and extremely trustworthy.

My AC wouldn’t run due to a short somewhere in the system. Shawn did a great job finding and fixing the short in a couple of hours, as well as testing my system to make sure everything else looked good!

Sean — Was very knowledgeable technician. Keep us informed & very prompt service and friendly staff. Everyone at McCullough is great. We have 17 rentals in Austin and they take care of them all!

McCullough has handled our Heating & AC maintenance for a number of years. Their technicians are well trained, respectful of property, and very knowledgeable. McCollough also recently replaced one of our units and did a great job! I appreciated that they used an outstanding quality control inspector to verify that the job was done right. I couldn't give a higher recommendation.

We hired McCullough to install a new AC and weatherize several years ago and we also have them perform regular maintenance checks on our system. They are knowledgeable, dependable and honest. Josh was our most recent technician and he was very professional, careful and friendly. Josh and this company are a pleasure to work with. We highly recommend them.

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. Henry came by to perform spring service on Thursday 5/1/25. Very courteous and thorough. He advised of issues with A/C system, and made arrangements to return to install another intake and clean motor. Very good technician, listed all performance checks and was a pleasure to deal with. 5/8/25 Henry & Dylan returned to perform work. They were efficient, on time, performed the job in an excellent manner. Great job!

Nice work friendly people I will use them again

Polite, fast and professional.

Great experience! Thomas was amazing. Good communication, professional, and quality work. We got an inspection and after a couple visits our A/C is working way better than it ever was before. Felt like their quotes and recommended service were honest and fairly priced. Definitely exceeded my expectations and will work with again. Can't recommend the company enough and shout out again to Thomas for great service.

The McCullough representative who serviced my equipment was thorough, knowledgeable and personable. This is just like all McCullough people I have met through several years. I wish the appointment window could be morning or half day. It’s from 8:00-5:00. That’s long, don’t you think?

Josh was great- thorough, kind and informative. We love McCullough; they always take such great care of us.

Vladimir did an excellent job in serving our systems and found a burned out capacitor in one of our units. He replaced with a higher grade unit and all is well! Thank you for the expertise and professionalism!!

Responded in record time on a Saturday when other vendors didn’t even return my phone call. Technician was professional and knowledgeable. Had replacement parts on his truck. Great folks!

Appreciated his hard work and dedication to clear drain clog. Great personality made us feel very comfortable!

Great AC company, Ivan R. and his partner did a fantastic job. Worked all day and got it done. Great attitude and work ethic. Glad to be a McCullough Heating & Air Conditioning customer.

Dillion did a fantastic job and thoroughly explained everything he did. The repair went smooth and our AC works even better than it did before

Dillon was super helpful with our service request. Our AC was not cooling properly and he walked through a couple of options to explore the issue.

We’ve been very pleased with Dillon Revells, the technician from McCullough who has done our recent maintenance visits. He’s reliable, personable, efficient, and he explains things thoughtfully. We trust him.

My Infinity thermostat was rebooting continuously, James came and in few minutes identified a clog in the water drain that was activating the reset switch and the whole system was restarting

Professional, knowledgeable, friendly service for super reasonable rate!

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 ! On Jan 7, 2025 we needed our system checked. Thomas Ishey was prompt, courteous, and extremely helpful. I AM UPDATING MY REVIEW TO HELP OTHER HVAC CUSTOMERS OF ANY COMPANY. WE NOTICED OUR NEW AC WAS NOT AS QUIET AS WE THOUGHT IT SHOULD BE. MY HUSBAND CALLED CARRIER TO CHECK WARRANTY DATA. THEY SAUD THE UNIT REGISTERED FOR OUR WARRANTY DUD NOT MATCH THE SERIAL # DESCRIPTION OF OUR CONTRACT. WE DID NOT GET THE UPGRADED AC UNIT WE PAID FOR. McCullough team responded immediate ly and investigated. We believe them when they say person who input order entered wrong data. Hence, ticket for warehouse were incorrect and so was installation. They immediately found the unit we should have received and installed it. LESSON LEARNED!! TO ALL IF YOU WITH REPLACED SYSTEMS, YOU MAY WANT TO DOUBLE CHECK. Thanks to McCullough for fast replacement. We are just glad we caught it. AND YES, the correct unit is more quiet than the builder grade unit and should last longer.

I have air conditioning that works again thanks to Dillon. He was informative and then thorough when analyzing and fixing the problem. I will be using McCullough heating and air conditioning from now on. They send someone out quickly to fix your problem and they are reliable so I can’t recommend them enough!!

Excellent service and communication all around. Fast, easy and informative. Jensen was our point of contact from the beginning until the end. Highly knowledgeable and straight forward. Extremely pleased with the entire process!

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

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.

Shawn did an excellent job repairing my AC unit. I appreciate his coming out late (7 pm) to take care of it. Very professional in all respects.

Guillermo was very thorough, respectful and prompt!! Great job!!

My technician Dillon was on time, very friendly, and knowledgeable. He quickly diagnosed and repaired her problem in about an hour. He even gave the option of doing the basic repair or doing a little bit more that could increase the life of the system. I'll definitely call them again for our HVAC needs.

Best HVAC company. I will use them again in the future. Just had 2 a/c &furnace systems replaced. Throughout the whole process, there was clear evidence that this company has very good standards. The technicians were focused, courteous, used good workmanship. Alex Stevens was our estimator and he was very helpful in getting us the best equipment for our needs at a reasonable price. Their process includes a quality control procedure where an experienced tech comes over to review all details of the installation to ensure it was properly done and will pass code inspection. This is not a new concept, but who actually does that? That is one little example of what I mean by good company standards. Try them. You'll see what I mean.

Top notch company. Great products and great service. Responsive and treat their customers with care. I highly recommend

Was very knowledgeable technician. Keep us informed, gives 3 options on AC choices— prompt service and friendly staff.

Excellent service visit with Desmond G; on time and answered questions asked regarding the service performed and operation of the unit.

Great and timely service today ! Dillon did a great job. Thank you.

We had our entire AC system replaced, and while we ran into some early challenges...the leadership team at McCullough has really gone out of their way in the end to make things right and get it all sorted out. Very appreciative of Shelton and his team (Shawn/Sean was great!) who really took care of us.

Very happy with the work done. Sean explained what work needed to be done clearly.
