Our Most Recent Service Reviews

Great technician. Informed us of the good and the bad with our HVAC system. Elected to go with a UV air cleaner to mitigate mold allergies in the house. Told us to wait and watch one other issue, we did not need to spend money on a fix at this time. Great service, did not try to take advantage of the situation.

Technician did a great job explaining what all he discovered and the 2 repair options.

I was very impressed with Dillon's expertise and knowledge of our system. I would recommend him and McCullough for servicing A/C systems. Thank you Dillon and McCullough for your service!

He was very efficient and explained what he was doing with all the diagnostic equipment.

McCullough always comes through! Highly knowledgeable and trustworthy team of experts. We’ve referred to several neighbors and family members.

Dillon went above and beyond simply providing the necessary repair. He provided very helpful tips and advice on care and maintenance of the systems. I will definitely reach out to McCullough again for future repair and when I do, I'll ask for Dillon

Excellent Technician. Very professional. Timely. Courteous. My HVAC system is in good hands.

So happy with the quick service and Frank is so knowledgeable and helpful.

Class act. Best AC company in all of Austin, and no one is close to them.

Never had a bad experience with the McCullough team. Brian was timely, thorough and new his trade well. 10/10 - definitely recommended!

Professional, explained everything, patient, efficient.

Nice, clean, well done

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

We have booked our yearly tune-up and review of our systems with McCullough. I called and scheduled the meeting and everything went smooth and well. The team showing up consisted of Thomas and Guillermo, which showed up on time and courteously called before hand. They both performed all necessary checks and answered, probably, a million stupid questions from my side (new to this whole process). They also took initiative to provide advice on taking care and doing routine maintenance work on our own to protect our system and take good care of it. I am so thankful the team servicing us is kind, patient, knowledgeable and willing to share their wisdom and advice. This is what customer service should be! Thank you Thomas and Guillermo and the McCullough team. I can only thoroughly recommend the team as they are awesome. @Thomas --- appreciate your patience and our philosophical conversation towards the end of the review. Appreciate YOU!

McCullough is great—super attentive and communicative. Sean, who serviced my home, was fantastic. I had another company come out for a quote, and they were rude, tried to overcharge me, and insisted I needed an entirely new AC system. Sean was honest from the beginning and upfront about what I actually needed and was very kind. Thank you, McCullough team!

Great service, diagnosed and repaired within 24 hrs after working with another company that had 3 service calls over 8 days and could not fix our AC.

DeAndre Rodriguez came and inspected both of our AC units. He took time to explain things to me and showed me how to replace the filters. He was very helpful and efficient. Thank you!

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

Very professional ,courteous and on time.

I have worked with McCullough for a number of years. Always great technicians, professional, courteous, and respectful of property. Technicians are extremely component and are customer focused. Says a lot about the leader of the organization.

Desmond was very knowledgeable and helpful.

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, Brian and the entire team at McCullough!!!

Kyle was great. Very professional and answered all my questions. Thanks.

Kyle was awesome, very helpful, nice and knowledgeable.

I woke up to a hot house. I called McCullough and they were able to send someone today. Alonzo came to my house and was extremely knowledgeable and explained what was happening to our AC unit. He gave me several options on how to fix it and all in all the AC unit was cooling within less than an hour from when he arrived. I will always use McCullough.

We had a leak in a tankless water heater . The technician , Erik , was very thorough to ensure that the issue was fixed. He also redid previous work from another plumbing company to get it to code. We appreciate his detail oriented approach to get our AC running.

Thanks to Brian for a careful, thorough, and professional job.

Alonzo was quick, personable, and most effective solving my hvac problem

McCullough was excellent as usual. Highly recommend them for all your heat and AC needs.

Kyle did an excellent job. He had great feedback on the health of my HVAC system and a low cost improvement to ensure the reliability and longevity of my compressor.

Not keeping the time frame even if its whole.day. expensive diagnosis for.everything ,not fully satisfied yet.of their work

Mitchell is the best service tech we’ve ever had at our home! He educated us on many issues helping us better understand our wonderful HVAC system. His work ethic and friendly demeanor are noticeable. McCullough has always provided outstanding service and today was no exception. We are grateful Mitchell was our system inspector today.

Great Inspection!

Dillon and everyone on the McCullough Team are first rate. All my questions and concerns are addressed and the knowledge of the technicians is undeniable. Dillon is a great asset to McCullough. Thank you all for the pride you take in your work.

Kyle at McCoullough came out to service our HVAC late on a Friday night after our roofing contractors caused an issue. He was able to quickly identify the presenting issue and resolve it. However, he went above and beyond to make sure that the unit was functioning as expected. It was not. He discovered that there was an additional issue - also caused by the contractors - that would have only been found with a full assessment of the system. Highly recommended - great work ethic and thoroughness.

Henry and Josh just completed my semi annual checkup before the cooling season gets going in full gear here in Austin. I know Henry from previous service. My first time meeting Josh. They are both friendly, respectful, knowledgeable and efficient. They are both dedicated to exceptional customer service and they just delivered it. I can’t ask for more from anyone or any business. McCollough does a great job with their employees. Everyone has been a pleasure and a privilege to deal with. Last December I did have to replace one of my heat pumps, a Lennox with a leaky coil. Stay away from Lennox at all cost. They have had coil issues for years and don’t properly own up to it. I have replaced 3 Lennox coils in 6 years. McCollough is not a Lennox dealer, another reason to love and respect them. When I replaced that system I went with a Carrier system from McCollough. So far it’s been great! My salesperson was Troy. He did an exceptional job. It was installed by Bruce and Thomas. They were great, as expected. How they are able to get those big air handlers into the little holes in the ceiling without ripping up the house is nothing short of amazing. If I have to replace anything again I want Bruce and Thomas to do it. Thanks very much to McCollough and it’s great people. I can’t say enough good things about this class operation.

Sean provided wonderful customer service and knowledge of HVAC system.Very efficient, professional, and friendly

Desmond Lopez was fantastic. He was knowledgeable, courteous, and very informative about our AC issues. Really, I can not say enough things about him. Our issue was resolved quickly and we were very happy with the resolution of the service experience.

Henry is very professional. I also really appreciate his integrity. During his work on my AC unit he accidentally broke part of my system that was only needed for heating. I would have never known until cold weather set in and maybe not even then. The result would have been another service call and more fees. Instead, he came back another day with the correct part and fixed it at no charge. I like working with people and firms that have those kind of ethical standards. In a second visit from McCullough to fix my intermittently non-working air conditioner, Dillon promptly fixed the issue, explained what was wrong, and showed me how to restore my system if the same problem occurred again. Once again saving me additional service future service fees.

Alonzo has been our service technician at McCullough several times. He is always punctual, polite, thorough and careful to clean up. I appreciate the detailed report we get in an email after each visit.

Pre-season A/C service. Sean was very professional, everything was working correctly and in good shape.

Sean was very polite.

Kyle was super helpful, knowledgeable, and professional. Fully recommend and will use them again.

Professional, great customer service and experienced technicians take the time to do the job right. Recommend their services.

There were some problems with the equipment, but the team kept coming and working on it until I was up and running! Very respectful of my home and apologetic for the inconvenience.

Dillon was great, thanks for the quick and easy service 👍

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

Henry was very professional, thorough in his evaluation, and excellent in explaining his diagnosis. A real asset to the company.

Great service and peace of mind for my AC unit with the coming summer. Heads up phone call before service that was quick,, efficient, and clean.

Henry and team did a wonderful job from start to finish. I had a Lennox AC coil that was leaking and near the end of warranty. Henry and team worked with me as we went back and forth with customer service trying to get the warranty confirmed, other HVAC repair places would probably not go that far to help. Henry replaced the coil and got everything working great, no more leaks

I’ve done business with McCullough for several years now. the did multiple repairs on my low-end, crappy DR Horton installed AC unit until I decided to upgrade to a high quality HVAC system. Desmond in particular has been a regular. He’s awesome. Highly trained, polite, friendly, and efficient. The same is true of every other tech they’ve sent out. Most important is that the company seems to have a highly trained, stable, competent staff. They are also highly response if I call them with questions. I don’t know that they are the cheapest, but cheapest isn’t always the best answer. Quality is what matters in the long run and I think this company is a quality organization. I recommend them without reservation, whether for regular maintenance, repairs, or a new system.

He was on time. Considerate of my property and bestest of all loved my dog.❤️

They were very friendly and performed heating maintenance. Always asking if I had any questions about the service. Will continue to use them.

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

Dillon arrived on time. He was professional, knowledgeable, courteous. He gave his assessment of the ac problem and gave a recommendation for repair. I appreciate his honesty and excellence in his job.

Thomas called to provide his arrival time, and showed up at that time precisely. He carefully inspected the inside and outside units. He also installed my new filter for me, and said all was well, however, that I needed a new fresh air UV. He informed me of the price and I gave him my approval to order it. He ordered the UV unit, and let me know it would be in early next week, at which time they would call to schedule an installation time. I would highly recommend Thomas for his services!! He did an excellent job!!

Had the best experience with McCullough !! Our heat wasn't working and I had had another company come to fix it but they weren't offering up any solutions for the issue other than waiting for.. honesty Im not even sure what. Heat typically isn't that important but this was during a colder spell and we were pretty cold inside !! I reached out to McCullough for a second opinion and the technician that came out (Frank) was AMAZING. Super thorough - quickly diagnosed the problem and was able to fix it just as fast !! I'm so grateful to have found this company and will definitely use them again !! Thank you again, Frank!

They are always great! Service tech was courteous and professional and was careful to put booties on whenever entering the house.

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

Mr. Harris answered my questions thoroughly

Called McCullogh Heating & AC for a second opinion after the first company I went through started suggesting expensive maintenance and suggesting I might be needing a full unit replacement on a perfectly working AC. They immediately scheduled a same day appointment that arrived on time, their technician was thorough with the inspection, explained every test and result. 5/5 will use them again next year for my AC check and maintenance. Update 2025. I've used them a couple of times more for preventative maintenance and to fix a broken AC unit. Still 5/5.

Thomas and his trainee did a great job with our spring maintenance. They were very fair and thorough. My one complaint is that they didn't show up until almost 6 PM and had an all-day window. The communication was poor from the company. But once they arrived the service was great.

Great service! Alonzo came out on the same day and accommodated our needs. Found the issue fast and solved it with a fair price. Definitely recommend if you need good and fast service!

Shawn May was incredibly helpful and professional. His work was deeply appreciated, and the other coworker with him was as well. Didn’t get his name, but they did an awesome job.

Very positive. The serviceman was knowledgeable and professional.

Shawn effectively and efficiently resolved our cooling problem; he was able to zero-in on the issue and insisted on replacing the problem-capacitor with the recommended OEM part even as he had to come back the next day just to install it at no additional fee. He was so considerate of our home that he had his own boot cover on as soon as he stepped into our home. Pleasant and comfortable to work with. Will definitely engage McCullough next time.

Our service tech Desmond was wonderful and super knowledgeable. Would love to work with him and McCullough again!!

great, responsive and no complaints, got the ac back working

My wife and I are very happy with Junior De Jesus’ work on our McCullough A/C system. We recently began struggling with maintaining a similar temperature from one end of the house to another. Jesus diagnosed the problem as a faulty remote thermostat. Within a few days the new thermostat showed up and Jesus installed it. Problem fixed! We are very satisfied with the quality of McCullough’s technical staff. They know their stuff.

Desmond did a great job, and was very honest and helpful, and didn't try to oversell me which i appreciate!

McCullough was excellent as usual and Shawn was very helpful and knowledgable. Highly recommend them for all your heat and AC needs.

McCullough was able to schedule my AC "second opinion" appointment for the morning after I called. Shawn showed up to my rental property promptly, did his inspection and called me twice to discuss his findings and his recommendations. I appreciated his courteous, professional advice, and will call McCullough again if I have a similar AC issue.

McCullough came responded quickly, came out to assess my H-VAC system, gave me a quote on each component separately. Sent a contract via email, scheduled the rapair quickly and came to do the work when they said they would. Responsive business.

Motor failed on electric HVAC system, called into MCCullough and was able to schedule an appointment for the next day. Desmond arrived after 30 minute notification, professional and very knowledgeable he verified problem, provided short time fix while we waited for part to arrive and rescheduled repair for following Monday. Again Desmond was very courteous and professional, changed out motor and checked system to make sure everything was in working order. As a still privately owned HVAC company in Austin wouldn’t hesitate to have McCullough to do yearly checks and repairs. Thank you.

Very nice, fast & efficient!

Mitchell was so professional, and patient to address questions about our new system. Very clear and thorough explanations to me and my partner. Made programming adjustments to reduce winter heating bill and gave easy-to-follow advice on keeping the system in top shape.

Very happy with the services. Dillon was great, he knew what he was doing.

Very helpful technician

thank you, Kyle Stirling, for the excellent service. We’ll definitely use McCullough again. Best Austin HVAC 👆

McCullough came out on Fourth of July to help us with our Hvac. Wonderful work by Nick. Thank you.

Kyle was great, thorough and efficient.

Alonzo was very professional and extremely nice.

Excellent and thorough service. Mitchell diagnosed the problem and was able to rule out any other issues. Always top notch service

I’ve been having issues with “dirty sock syndrome” on new units with aluminum coils, but the service team has been very willing to help address these issues

Desmond punctual on time. He was nice to explained my ac and heating system. He informed me about my periodical maintenance tasks to make system run efficiently. I was pleased with his professionalism.

This was the first time using McCullough for scheduled maintenance. The technician, Junior, thoroughly explained everything he accomplished today and his explanation of potential issues that could arise going forward was very reasonable and supported by photos. I look forward to his return visit.

McCullough Heating & Air Conditioning Great Company Prompt and efficient Service.

We have used this company two other times for complete AC and heater installs at other houses. They are professional and do a good job. We have felt their prices were competitive and fair. Their installers take care to keep the area clean with drop cloths and shoe covers. They wear masks and use good Covid precautions. We will continue to use their service. Update: McCullough tech, Mitchell Reaves, did our annual inspection of our heating/cooling system this week, He was efficient and pleasant. He checked out our two systems and answered all of my questions. This annual inspection was part of our contract for maintenance that we pay monthly and is reasonably priced. We will continue to use this company.

Junior was awesome. Took time to explain what he was doing and things that he was concerned about. That way there aren’t surprises in the future. Very personal and nice as well.

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. Dillon phoned prior to arrival and showed up on time. My annual maintenance went smoothly and Dillon explained what he was doing the entire time. I would highly recommend this locally owned business.

Solid experience! Quick and easy.

He was friendly and kept troubleshooting until he found the root cause of our leak.

Richard, Israel and Arthur came out and did wonderful work. They were very professional and nice.

Excellent service as usual.

Can't comment on quality of installations or repairs, but I can tell you about my experience trying to get a quote. I've already had my HVAC diagnosed more than 4 times over the last 4 years. I know my evaporator coil needs replacement. I know the make, model, and even the serial number. All I want is a quote to compare against other HVAC companies. When googling, I came across "Free In Home Estimates" for this company. I have them a call and was told there would be a $75 trip charge and diag fee. I replied that I do not need a diag. I can show pictures of the oil leaking and the serial number tags if they like. It's already been diagnosed 4 times and no technicians had conflicting stories. I need an evaporator coil. Many HVAC companies will charge you a trip fee, come out and look at it for 5 minutes and then try to sell you a $20,000 new system that should cost less than $10,000. I am kinda of tired of playing that game. If you want my business just tell me what you charge for the service! So, I hung up. Fair enough. You have to drive and you want a trip fee so as not to waste your day. I get it. I don't agree. That could be that. However, I get a text and two voicemails after that saying "sorry for the confusion. I asked around and we can give you a free second opinion. Call me back" So, I call back. I am then told it would only be considered a second opinion if I provided up front the record and quotes from the other companies. Well, that defeats the purpose of shopping for quotes, doesn't it? Have you seen how people bid on the Price Is Right? So, we circled back to the $75 trip charge. Anyway. It's spring and hovering around 60 degrees. I managed to get a free diag from three other companies immediately after I hung up. I'll choose the one that communicates the most clearly with the least amount of B.S. to do a job that costs thousands, for which there seems to be same day availability.

Joel was very thorough and explain potential issues so that even I could understand them.

Great service!

We had an issue with our heating system during the recent freeze and Shawn was able to quickly identify and solve the problem.

The best way you can tell a top notch service in my opinion is how they handle a situation when it goes wrong. Due to incompetence from a general construction contractor who did work on our building last year some AC units were misplaced and mislabeled causing work to be done on a wrong compressor unit than the one intended which was nearby. The service manager himself answered the call promptly and professionally, fixing the situation and made everything right the very same day. Joey the manager was polite, friendly and professional. He provided several options and full warranty on the necessary repairs. I will definitely use this service in the future for HVAC installation or service.

Shawn was courteous, professional, and knowledgeable.

The young man was very knowledgeable, pleasant and courteous. He arrived on time requested.

The Technician Junior DeJesus, checked with us before during and after the visit and did a great job. only good things to say about McCullough.

From start to finish they were very professional and went above and beyond. On the sales side, I found it hard to peel back the layers of each company and decide which one to go with for my new A/C unit. Alex was great on the sales side, helping me understand the differences between units and ensuring that I had the best one for my house. He had been in the business for a long time and could tell he even knew his competition well. He gave me the best price and the best overall service. Not to mention the install team was great and easy to work with. Today, I just got sent a gift from Tiff’s Treats from them and it made my day. All around great company to work with!

Service was great. Checked everything.

Great technician, we are pleased to stay comfort club members. The only thing not ideal is scheduling windows are all day.

On time, courteous, thorough and knowledgeable.

The technician Alonzo provided a thorough diagnostic of our AC unit. He was very courteous and kind.

Alonzo was a courteous and efficient service rep and who provided excellent service!

Nick came out and diagnosed the problem with my 14 year old heater very quickly. He gave me options to repair or replace. He was prompt and professional. Follow-up: (a few months later) I called to have my heater fixed and Junior de Jesus came out and repaired my issue. He was efficient, had notes from Nick’s visit to give him a place to start from and completed the repair flawlessly. He was super-nice too. Both Nick and Junior spoke to me like I’m an intelligent person; no ‘mansplaining’ here! They were also dressed professionally. I highly recommend calling McCullough if you have any issues with your a/c system.

We have had some issues with bedrooms being either to cold or to hot since last our new system was installed last August. Alvin the service tech came in and quickly made some adjustments to our duct work dampers. He is going to talk with his supervisor regarding doing some additional testing on our duct work.

Fantastic service and super friendly & professional. Saved us a ton of money — thank goodness we called them for a 2nd opinion. They will be our 1st look from here forward.

A great experience with McCullough last month. I have an older Lennox furnace that I am trying to get one more season out of and I needed some troubleshooting because it was working fine but shutting off intermittently. The service call I received from McCullough was exemplary. The tech took time to really inspect and diagnose what the issue could be. He also listened to me to understand what had already been attempted to fix it. After a short time he solved the problem. It was actually a simple, analog fix yet 2 other companies who came to look at it completely failed. McCullough did the right thing and actually repaired my unit. They are now first on my HVAC referral list. The 2 other companies that came to look at it were a disaster. One of them just basically threw a part at it without any sincere effort to perform a diagnosis. The second company was even worse as their 'tech' was only interested in selling me a brand new HVAC system and essentially pretended to inspect my furnace and said it was beyond repair. In contrast McCullough really helped me out. Their tech did also discuss the need for eventual replacement (its a 27 year old HVAC) but he did it AFTER repairing my furnace and in a way that didn't insult my intelligence. When it is time to replace my entire system, McCullough has earned the right to be my first call.

Alvin was really good at his job. He showed he cared about us and the type of work he did.

Heater temperature wasn’t getting hot and Alvin came and got it working again. He was professional, courteous and fixed it quickly!

I have the deepest appreciation for Alonso and the full McCullough team. My home wasn’t heating during the freeze, and Radiant told me that my entire HVAC would have to be replaced and quoted me $15,000. Thankfully I had some good folks around me who told me to reach out to McCullough for a second opinion. Not only did they show up the next day, they confirmed my system was in good working order, adjusted my thermostat to ensure that the home would continue to heat, and did it all for free. This company truly puts the customers interests first, and doesn’t use a hard situation to try to scam someone out of a sum that is equal to the down payment of a house. McCullough has earned a lifelong customer.

Mitchell was amazing. Knowledgable and very helpful.

Henry was great, saw exactly what was wrong and explained to me all of my options. Great customer service. Also had Mitchel out to look at our other unit. Both techs were great

It was a necessary visit to get the ball rolling on a solution to a problem for which no one has offered a solution in the past six years. Their visit led to a visit from Troy later in the day, who was able to identify the problem and a solution that is significantly cheaper than replacing all of my heating ducts.

Our technician, Alonzo, completed an exceptionally detailed diagnosis on our system and provided us with an estimate that included only what was necessary. Very much appreciated!

I've lived in Austin a very long time, have managed many properties and dealt with too many installation and maintenance companies both here and abroad. I have found working with McCullough to be the best experience I've ever had. They were honest, prompt, communicative, tidy, with impeccable follow up. If only the rest of the world worked the way they do, life would be so much sweeter. Thank you McCullough Heating and Air.

Henry could not have been more professional in resolving our issues, and identifying items we might need to watch out for in the future.

Great first experience with McCullough. Alonso was courteous and efficient!

Fast friendly service! Very detailed oriented explanations on what the problem was and how they would fix it!

Nice work friendly people I will use them again

Shawn was phenomenal!

Our technician, Nick, was very professional, knowledgeable, and courteous. He answered our need for help outside regular business hours and was able to quickly diagnose and fix the problem with our furnace before lack of heat became a serious issue for our family. Thank you!

Henry could not have been more professional in resolving our issues, and identifying items we might need to watch out for in the future.

Very pleased with McCullough Heat & Air, as well as our technician, Desmond. Good communication, knowledgeable and professional.

They were very conscientious.

Excellent Technician. Very professional. Timely. Courteous. My HVAC system is in good hands.

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

Great service, diagnosed and repaired within 24 hrs after working with another company that had 3 service calls over 8 days and could not fix our AC.

Always professional and reliable

I really appreciate Joel's thorough evaluation of my heat pump. He discovered a leak in my system and put a plan in action to fix it right away. He showed up on time, texted me 30 minutes head of time to let me know he was coming, and was very courteous and professional. I am very happy with the service he provided and will use the company again if needed. Thanks Joel!

I had Nick Staggs as our technician today. He did a great job. Got the AC back and running. Also inspected the rest of the unit and provided great feedback on our system. Overall happy with the fast response and service provided .

I will only call them from now own. Another company quoted me $1200. McCullough came out for a 2nd opinion and I only had a loose wire. Fixed it at no charge

Mr. Mitchell Reaves works for very reputable and the best company McCullough Air and Heating in Austin. He took care of the A/C ductwork issue I had. I always ask for Mitchell to take care of the problems. He scheduled appointment same day and knew the problem immediately and fixed it in no time. He explained thoroughly and in detail the issue of the HVAC before fixing it and after it was fixed. He is very professional, very knowledgeable and very experienced and gives customer care quality/advice/service. I would recommend Mitchell to anyone who needs any kind of A/C repairs, duck work or installation. Thank you Mr. Reaves for providing outstanding service to me and all your customers.

So happy with the quick service and Frank is so knowledgeable and helpful.

Mitchell Reaves is extremely knowledgeable and adept at problem solving. He was very thorough and gave helpful explanations in his assessment. I will request his assistance for service in the future.

Great service from Alvin and McCullough!

Very Professional!

This was my first time using McCullough Heating and Air Conditioning. It was very easy to call and make an appointment over the phone. The technician, Mitchell, quickly diagnosed the problem and got it fixed and the heat working! He was very knowledgeable, and he didn’t mind me looking over his shoulder and asking questions as he worked. -I am happy with this service call visit; it was a good experience. I will call McCullough next time!

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

McCullough contacted me immediately for an appointment the next day. Unfortunately the technician and I could not connect to set the appointment during the appointment window.

Gilbert and Michael did a great job. They are highly skilled professionals dedicated to their work. We were very happy with their efforts. McCullough has great service people on their team.

He did an absolutely thorough job. We are very satisfied with him and McCullough.

Excellent service. Maintenance on AC. Service man very personable and professional .

Excellent service highly recommended.

Gilbert and Ricardo were professional and very easy to work with. They were very efficient and kept the areas clean and tidy and were respectful in our home. I would 100% recommend these guys for any installation.We feel we made the right choice with McCullough heating and air for our replacement needs. They were very flexible and even worked on the weekend to complete our install! We are more than happy with the final result!

Desmond was a great help getting my heater going. I would recommend you anytime.

I got into a bit of a panic when my heater stopped working but McCullough was very quick to respond with a next day appointment. Nick diagnosed and identified the problem quickly and was the most knowledgeable, informative person I’ve had the pleasure of dealing with in quite some time.

Technicians Joey, James and Alvin have all been at my house doing excellent work installing my new state of the art HVAC equipment. They’ve been great communicators and persevered to make sure everything was done right. I’ve been with McCullough for many years and they never disappoint.

James did a fantastic job, no high pressure sales pitch, just great service! I'll be using McCullough !

Great experience with McCullough during the latest cold snap. Mitchell showed up on time, figured out what was wrong, and got my old Lennox furnace up and running. Courteous and professional and on time, can't ask for better.

James was great. He was thorough and addressed all my questions. The team at McCullough did a wonderful job with the installation and upkeep on my hvac!

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

The system my dad has was installed back in 2010 by McCullough and they have serviced the system since then...I have always been more than satisfied...this specific service/repair event, even more so...the heating kit on the Auxiliary system was no longer working and a new one was ordered...this is the system in my 86 year old father's home, so his warmth is paramount to me...the new heat kit was faulty and the service tech and McCullough coordinated finding a replacement and searched the city and found one...all was completed by 1:30pm and well before the storm hit...my dad's home maintained a comfy 72 degrees...I am very thankful and appreciative...

I really appreciate Joel's thorough evaluation of my heat pump. He discovered a leak in my system and put a plan in action to fix it right away. He showed up on time, texted me 30 minutes head of time to let me know he was coming, and was very courteous and professional. I am very happy with the service he provided and will use the company again if needed. Thanks Joel!

Highly professional organization. Suggested the optimal system replacement for an upstairs unit, as oppose to the most expensive. Suggested repair for another unit as oppose to replacement. Customer centric.

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

Great service. Had two older furnaces inspected to make sure all was good as we head into a cold snap. Super impressed by the level of detail given. Extremely knowledgeable technician who took the time to help me understand what was needed and what was optional to keep these units in good shape.

Always great service, dependable, and professional.

Professional courteous service . I’ll know if it works when summer comes around but am confident that they got the job done right.

Very good service

Awesome i customer service and knowledge of HVAC system.

I am so pleased with the great service I received today. Alonzo was very professional and respectful; he got right to work diagnosing the problem. He took care of the problem and put everything back the way he found it. Thank you Alonzo!!!

Great experience with the technician Alonzo and the Appointment desk. McCullough is the company to call when you wanna be sure the work is done correctly.

McCullough recently replaced our garage apt split unit. Then we had a full home inspection where the unit didn’t heat up. Nick with McCullough came out and explained these units are very complex with certain delays when turning them on. The inspector had not waited long enough (5-10 mins) for the delay process. Another quality job and product from McCullough at no charge to educate the customer on the new HVAC advances. Works perfectly.

Sean checked the Carrier heater for the winter months. He was very thorough and clearly explained what he did and some aspects of my system i hadn’t known. He was very knowledgeable and i recommend him.

Nick came out and diagnosed the problem with my 14 year old heater very quickly. He gave me options to repair or replace. He was prompt and professional.

McCullogh always sends very professional techs to our house. Alvin was great this last time. We have been a customer for years because this company does a good job and the techs are always friendly and kind.

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, for transforming my home into a more comfortable and enjoyable place to live with your incredible cooling and heating system.

Junior from McCullogh Heating & Air fixed the errors made during the A/C and heater installation in September. He correctly seated the motor and removed the paper User Manual that was stuck inside the gas heater. He turned up the fan volume and reset the error code. The fan now sounds like a gale force wind running through the vents. I wonder if the fan volume could be reduced and the heater still work properly. The extra dust blowing through the vents is stirring up my allergies. Junior, thanks for coming out!

Always on time and do a great job for a fair price.

Mccullough always comes thru for me. Purchased new Carrier about 4yrs ago from them and they handled all the warranties Austin permit and rebate. Plus Electric company set up. Setting up a service call they give you an all day window but service will call a few minutes ahead to give you a heads up. I do wish they could at least say morning or afternoon tho when i schedule.

Mr Sanchez showed up timely and was most knowledgable about my HVAC system. He found problem with sensor almost immediately and was able to provide estimated cost of replacement. He gave me an outlined plan of action and later followed through. Very professional and helpful. Thanks, James!

Henry did an outstanding job servicing my HVAC heating unit and explaining what was wrong and recommending specific maintenance work.

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

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

I have used 4 different heating and ac companies over the years and decided a couple of years ago to try McCullough. I had noticed on my walks that the family lived in my neighborhood and thought I should try them. The company I had been using before my last switch lied to me about needing an expensive repair I didn’t need at all. I have a maintenance service contract.with McCullough. I like the work they have done. I’m comfortable doing business with my neighbor.

Henry has great customer service. He is very professional, explains everthying in detail, and is very patient with my questions. Good work.

As always, service was great! Matt knows his stuff and a pleasure to deal with!

Micheal was great, very diligent in looking at the issue

Great work and professionalism.

Great company - honest, personable techs. Fair pricing and very fast and efficient service. Highly recommend!

McCullough Heating & AC went above and beyond in making sure I understood what was wrong with the system, showed me around the furnace, and showed me how to monitor the issue for the next time if it happens. I felt included, appreciated and understood. Thank you, Junior! (the name of the representative).

Great service. Easy to interact with HQ via text and schedule or cancel as needed. Really like that. Junior was great and went above/beyond to diagnose the issue.

Nick was awesome. Super helpful, very professional, and very honest. I will use McCullough again.

McCullough Heating and air Conditioning did an inspection/diagnosis for our HVAC/Furnace and demonstrated to be very professional, punctual, and collaborative. Shaun was professional, cordial, and knowledgeable. We are very pleased with their service and recommend them to anyone who needs their HVAC/Furnace system checked and maintained.

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.

Technician did a great job. Suggested an overflow control mechanism for AC later this summer

Friendly service on the phone, friendly and courteous technicians, speedy availability of parts, speedy repair.

Nick was knowledgeable, friendly and a great communicator. He quickly found the problem!

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.

Prompt, consistent service
