Peter and his team at McCullough did an absolutely amazing job on our AC replacement and installation. They had perfect timing, chose the best particular components that were needed, and followed up with a quality check immediately... all above the expectation! High recommend!

McCullough Heating & Air and Service Tech Henry Harris continue to excel in customer service. Henry checked heating unit for Fall, replaced air filter & made 2 reco’s that I approved without question after he explained the benefits of both! Very happy customer!!

Blake’s the man. He was honest, very knowledgeable, kind, and professional. Thank you Blake.

Prompt response, prompt diagnosis, and a prompt resolution. Dillon and Brian worked well together and even threw in some preventative care tips. Well done.

Nick was awesome. He came out to perform my bi-annual maintenance on both of my a/c units. He was very polite and knowledgable on all the questions I had. All the technicians I have had from McCullough have been great to work with. I highly recommend McCullough’s for any a/c problems!

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.

Still waiting on a call from Joey as mentioned by Clayton

My experience with McCullough is an A+. Most recently Charles has been to our home to inspect a non-working AC unit. He is professional & thorough in walking through issues and next steps. Amazing customer service.

Blake was very knowledgeable, kind, and professional. Thank you Blake.

Was really pleased with this company’s s service today. The Technician Eric was personable, proficient and honest. This is the third time they came to do seasonal service and I really appreciate the way this company does business.

Clayton did a great job and was very professional. This was a maintenance check. He answered all my questions. I highly recommend McCullough. Thanks Clayton.

Blake Eastland was excellent!

Richard and Arthur did a great job with the installation of our new AC. They were very professional, polite, kind, thorough, as well as protective of our flooring and home. Richard went above and beyond in making sure a couple of things were they way we desired. A new AC is a big investment and having Richard there gave us peace of mind is was done right

Blake serviced our three units and mini split today. He was very professional, knowledgeable and friendly. Blake took time to explain things to us and offer solutions to questions and concerns.

Everyone I’ve worked with has been great. Good attitude, friendly and capable. Eric has been here the most, lately and has been very conscientious!

My experience with them was really great! My air conditioning wasn’t working and I have two kids at home so I needed someone to check it out quickly, and they had Thomas to my house within a few hours of calling. Thomas himself was so kind and patient with all my questions and clearly explained what was happening and steps to fix it. And it worked! For me, trust is everything and after my experience, I know I can trust them to give me honest advice/service in the future. Never thought I would write a rave review for an AC firm but here we are. Highly recommend! Thanks so much, Thomas!

Great service! They added additional air vents in my bedrooms to help match the necessary sizing for my HVAC system. The team answered whatever questions I had and explained what they were doing as they were working on it.

Top notch service and a super professional technician named Josh! Definitely recommend!

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.

McCullough was extremely professional and friendly. I made a late night call and they came to my house after hours to ensure we could sleep in A/C. Their service was phenomenal!

Chris is outstanding!

Eric was super informative and very polite. Gave me all the options and was thorough and quick. Highly recommend him

Thanks to Maykala for a careful, thorough, and professional job. I am completely satisfied.

McKayla arrived promptly for the inspection of my system. She was thorough and communicated well, giving me excellent information on maintenance and products for keeping my new HVAC in good performance order.

Sean was great! Very professional.

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

Just had my Fall inspection with Makayla Morgan of McCullough Heating and Air Conditioning. Everything checked out great and we are ready to heat for Winter. Makayla was excellent. She worked efficiently and had everything checked with a few minor tweaks to the indoor part of the system to get everything sound and ready to go. Makayla is knowledgeable and a good Tech. She explained everything she did, what she found, sent me my the invoice and was on to her next appointment.

Great service by McCullough. Their techs are first rate. He did a great job, quickly got my AC running again.

I’ve been a customer of McCullough Air Conditioning for 9 years. My air conditioner was not cooling. I am very pleased with Dillon, Brian, and Joey. Dillon took the time to explain to me what was wrong and went to work on it. I really appreciate all you do for me. They did an awesome job. Thank you!!!

I appreciate the attention and expertise that tech EJ provided for my heating issue today.

Honest and detailed assessment of issues. Explained next steps well

Hvac 2nd opinion. Chris was prompt, polite and knowledgeable.

Kyle did a great job inspecting, detailing all the work on my +20 year old HVAC system he completed, and recommendations for its future maintenance. Will use the company again as needed.

My air conditioning went out on Saturday at 2pm just hours before a housewarming party. Within a couple hours the technician, Makayla, arrived and quickly figured out the problem and was able to swap out the part and get the system running. Great experience and they truly saved the day.

Henry Harris was thorough and professional during his inspection. He took the time to explain his findings clearly and provided helpful insight into the next steps. I appreciated how informative he was, which made the process much easier to understand. I look forward to working with Henry Harris again on future inquiries for this property or others.

Blake came out to our house to check our AC system. He was able to identify and remedy the problem within a short time of being there. He quickly obtained the parts necessary to fix the AC and came out immediately to repair the system. We noticed an immediate change in our system and have had no problems since.

Very pleased with Thomas' service on our furnace. Professional and knowledgeable. Very nice and personable.

Vlad is a true expert and masters level electrical and air conditioning guru. When our 5 ton Carrier unit stopped cooling, he was able to find the leak quickly and get the replacement here fast.

McCullough has been taken care of us since we put in our unit in 2019! We are part of their comfort club and they come out a couple times a year to check our system and change our filter. Very professional.Christopher Rose came out this time and did a great job! Very happy with this company! as far as I know, it is locally owned and not corporate owned like so many businesses are these days.

McCullough came out the next day after we called and thoroughly checked our dying 4 ton 2003 model central air system. Since this system used old style refrigerant (now banned) we agreed repairs were pointless, and are now working on options for a high efficiency replacement. Very affordable service visit.

Dom was excellent. He came for QC following a particularly difficult installation. I had concerns after my HVAC installation, and Dom helped me feel reassured that everything was good. In addition, he went above and beyond to help me with my thermostat.

Our 30 year old AC was dying a slow death, and we decided, after a couple of estimates, to go with McCullough on a new system (we ended up having to get a condensing unit because our attic is foam-insulated). We could not be happier: the installation went very smooth, with two very courteous techs, and the end result is a new unit that is quieter and does a much better job in providing cool comfort throughout the house.

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

Thanks to Maykala for a careful, thorough, and professional job. I am completely satisfied.

Joel was honest, respectful, kind, and throughly explained what the issue could be. Joel went above and beyond to make sure I understood all repais in detail . My A/C unit was working properly by the time Joel left.

Makayla was thorough and courteous. Gave me great information on how to keep my system running efficiently. Great service!

Excellent customer service and accountability. Friendly technician took time to explain everything.

Blake was Awesome, very knowledgeable, helpful & friendly! He got my system running at No Cost (with coupons I received in the mail) until I get an estimate on a full HVAC replacement! Amazing service, I would give him 10 stars if I could! Thanks so much for quality service!👍😁

Kyle ordered the part needed to fix my ac and kept me informed as he tracked its journey to Austin. He repaired my ac system expertly once the part arrived. Job well done!

All areas were perfect from scheduling to appt, explanation, price, efficiency, and how professional and kind Clayton, the repair technician. I would absolutely recommend this company.

Happy with the service they provided.

They are always great! Service tech was courteous and professional.

Same day service saved us! Pro tip: sign up for their bi-annual membership.

The technician did a good job. However, I don’t understand why the things that are being corrected. Today were not taken care of upon the installation of the new HVAC a year ago.

Vlad Savinov & The McCullough Team were great to work with. It's nice dealing with an actual local Austin business that hasn't been sold to some nameless corporate overlord. Vlad was fantastic, diagnosed the issues quickly and got my AC back after a record setting 101 degree day.

Makayla visited for a diagnostics. Service was excellent and she was transparent about the industry, timelines, and pricing.

Vlad was prompt and professional, and offered a comprehensive diagnosis and options to address the problem.

Vlad installed a surge protector on my AC heat pump after a nasty Austin Electric power over voltage. Great and timely service experience along with very nice customer service!

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.

Our HVAC was failing to cool and technician Eric Suarez helped us resolve the issue quickly. It ended up being a problem with the thermostat and filter putting the unit in a bad state, which required resetting the unit. Eric was courteous, friendly, and professional.

Called to have my ac unit checked for the year, they said they don't check ac units anymore for the rest of the year only heating units. But for an extra 50 on top of there 149 fee they could look at the ac also.

Reliable service at reasonable cost.

Eric was amazing. He explained everything step-by-step, was friendly, and took care of the issue pretty quickly! A1 service.

Kyle Stirling stopped by my house on Thursday (Sept 18) around 1PM. He spent about an hour to diagnose and point out a refrigerant leak happening on my evaporator coil on my Lennox 5-Ton system. He gave me fair-and-square pricing on replacing the whole upper unit air-handler unit with a brand new one, and collected the 50% deposit of the whole price (labor and parts and additional refrigerant gas, if necessary). He informed me another crew from McCullough will return on October 1, 2025 to remove the existing air handler and install the new one, and potentially add refrigerant if needed. He finally topped off my refrigerant to make sure I can stay cool until October 1st. My experience with Kyle was great, and I do hope to see the same will happen when McCullough’s crew comes in on October 1st to replace my air handler unit.

Quick, thorough, and no complaints about the attic work required; also gave good advice on resolving the issues on my own if they ever recur in the future.

Our service tech did a good job of diagnosing the problem, ordering the air handler parts, and installing them after they arrived the next day at our home. He even returned after leaving the job to fix an issue caused by equipment installation. The tech recommended that we install a surge protector/voltage monitor to protect the replaced equipment from power surges and brownouts. Unfortunately the SPD recommended by McCullough will not do what the tech said it would do, so there needs to be better communication within McCullough so that in the future misinformation is not conveyed to the customer.

By far the best AC company around. This is my third year using them, and they are always honest about what it needs, if anything at all. They’ve caught things that no one else has been able to catch. Awesome,

Kyle came quickly and worked efficiently. He is a really respectful guy and great at his job! Thanks for fixing our HVAC y’all!

The drain pipe was clogged and water was seeping through the flow. Admittedly, I had not checked nor really understood the system. My husband passed away this year and he managed the hvac system. Dillan was both friendly and professional. He did not act rushed and took the time to explain the system to me.

The technicians Thomas Ischy and Makayla Morgan were very thorough and knowledgeable. He was respectful and did a great job at replacing the fresh air zone damper and control. Highly recommend this local business to anyone that needs help with AC and heating.

I don’t think I was being targeted as a rube, but McCullough quoted me around $14,000 to replace my AC unit, which they said definitely had a blockage. The actual problem was that my main attic duct had been ripped in two by raccoons. A neighbor fixed everything with aluminum tape for $30 and the AC runs fine now. I’m sure they’re professionals and they’ve gotten great reviews here, but shop around for other estimates.

The technician Thomas Ischy was very thorough and knowledgeable. He was respectful and did a great job at replacing the fresh air zone damper and control. Highly recommend this local business to anyone that needs help with AC and heating.

Reliable service at reasonable cost.

Shaun has been providing me continuous updates on my repairs and providing excellent customer service.

Shaun has been providing me continuous updates on my repairs and providing excellent customer service.

Vlad did a great job explaining what was needed, was very courteous, personable, and professional.

We have been extremely pleased with McCullough Heating and Air Conditioning from the beginning. They came on a weekend to fix our AC and discovered it was old and not repairable. It was during a heat wave and they immediately brought a window unit to make it bearable until they could install our new unit. I highly recommend this company. All of the staff from the initial visit to completion were, friendly, courteous, professional and just top notch!

Evan, as our project was super. He went thru the hvac replacement options as to what system would be best for us. Big decision for us. His friendly, personable, and professional manner put us at ease. I was a little surprised, then pleased, that installation would happen the next day. Mark and Chris were friendly, professional, and went about their duties in an orderly and calm manner. All 3 of these men seem to like their jobs. Good guys! That's important to us. The cost was good, too. Our previous system was 25 years old and had been working well until it suddenly crashed. Knowing it was old we had been setting aside funds and were happy to see yalls price was lower than expected. Yea! The system is working well and electric bill is noticeably lower. Yea! Thanks all We're grateful.

Great service. Thomas showed up in no time and diagnosed the problem with my AC, and resolved it quickly. He also did a full check of the unit to make sure everything is good. He is knowledgeable, professional, honest and efficient. I will most certainly use their services again. Thank you Thomas.

Price was fair mkt but they don't balance the air, whatever that involves, and any duct work is extra at high prices. IOW your new unit might not cool house evenly, unless you pay a whole bunch more. Seems like something other companies would include

Nothing but great things to say! Evan came by to inspect a non-functional mini split that had been installed by a different company AND that had become a conduit for rodents coming into our air conditioned converted shed space. EEEK, am I right??! Evan took the time to investigate and explain how the rodents and other pests were coming up the lines and into our space due to a too-large opening that had not been sealed AT ALL by the other company. He talked to us about our heating and cooling needs and came up with an option to replace the mini split with a new unit. Ultimately, since this particular space is so small, we decided to continue with a window unit, since it seems to be performing better than the previous mini split system. However, due to Evan's knowledge base and McCullough's fair pricing, we will be calling them in the future for our main house's climate needs. Thanks, Evan!

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

The visit went well.

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.

Processional and punctual. Very thorough and a nice respectful technician.

I was told by another company that my compressor was dead. Thankfully Eric did some due diligence and had my system online in 20 minutes or so. An honest competent technician is refreshing. I wish I called McCullough first.

My AC stopped working on Saturday. Called McCullough, and they had a tech to our home first thing Sunday morning..The tech, Sean, was professional and prompt. He checked our outside and inside unit, and had the issue diagnosed within minutes. He explained the cost and set our mind at ease. He worked swiftly and fixed the capacitor, what seemed like minutes. I highly recommend McCullough and have nothing but high praise for their tech Sean.

Evan Young and McCullough AC was outstanding - they helped us think through a 2 stage system and zoning upgrade for upstairs and downstairs, highly rcommend!

I am really happy with the service provided by shawn and his team. They fixed my AC coil got it working in a day.

Great professionalism, efficient and fast.

Josh was informative, professional and performed our cooling inspection and general maintenance on our system. Happy we have a recurring maintenance plan with McCullough.

Great technician! So honest and knowledgeable!

Very professional service on two A/C units. I suspected one unit was low on refrigerant and Clayton confirmed that. It was $105 for 1 pound of refrigerant. He replaced one of the filters and hosed out the condensing units. He also confirmed that I correctly wired my new smart thermostat.

Have installed 2 systems in the last 3 months, both replaced A/C & Heat systems were over 20 years old... I appreciate the consultive and honest approach Alex brought. Once we made the decision, we have been pleased with the install and results! Highly recommend!

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

What a fantastic experience! Our air conditioner stopped working and after meeting and getting a quote from a popular company we decided to get a second opinion on options and costs. Henry Harris knows his stuff! He- and the rest of the McCullough team- are professional, communicative, prompt and extremely knowledgeable. Henry was a pro and the company was great to work with and we didn’t feel “zip coded” in their quote. In less than 24hrs after meeting, our air conditioner was running, again. Thanks, McCullough Heating and Air!

great service and very prompt!

Charles was an extremely professional and friendly tech. He respected our home, answered all questions in an informative and friendly manner, and was very thorough with his work. Can’t recommend the company and Charles enough

Clayton was our tech for a recent AC outage due to a clog. Besides fixing the issue, he gave me tips on preventing the problem in the future, and reminded me to order filters. Great guy & good service.

Fantastic job in replacing my HVAC system. Work was done with a minimum of household disturbance and my system is performing excellently!!

Eric is very knowledgeable and provides great customer service.

I needed my 25 year-old HVAC system replaced and McCullough submitted the best price and equipment out of four companies. Evan was our project manager and was very patient and responsive to our numerous questions. Ricardo and Ivan removed our old system and installed the new Carrier equipment. Both were very professional and patient. Their attention to detail was refreshing. Dominique followed up with a QC appointment and he was just as professional and patient with our many questions. I won't use any other HVAC company and highly recommend McCullough to my friends and neighbors.

Charles did a great job diagnosing and explaining varied options for how best to address the issue at hand. Concise, clear and very helpful.

Makayla was wonderful, she really was thorough and timely. She called and provided a ton of photos without being asked. The turnaround was quick from estimate and job close out! Really can’t say enough good things, biggest bang for my buck in some time!

5 Stars for McCullough Heating and Air Conditioning - I would highly recommend them based on their expert knowledge. Guillermo Mata was extreamly professional and ordered parts that arrived in 1 hour. He was able to diagnose my HVAC accurately. Thank you for your service.

Eric is very knowledgeable and provides great customer service.

Shawn stopped by during emergency hours and tried hard to get our unit going. He was so kind when he broke the news to us. Evan and the installation team (Richard & Arthur) were hands down the best. Evan immediately set us up with our unit, explained options & called to plan our install that next morning. Richard & Arthur were organized, neat, just nice guys. They waited until our unit was performing as it should. They did not just install and leave. Local company with that local care. Amber (sales coordinator) assist me with my questions & she was extremely helpful.

Henry was very nice. Showed up on time and completed work in a timely manner and explained everything very well.

Excellent service.

The gentlemen was excellent and taught me about the unit and how it works. He most importantly explained the issue.

Service tech was very friendly, informative and professional. Timely response and repair. Highly recommended.

Shawn went above and beyond! Highly recommend.

Very professional ,courteous. Wait time was 8am-5pm. Showed up after 5pm. Not acceptable.

Eric came promptly for both service calls, was professional, took time to explain what the issues were, went above and beyond when encountering an additional issue, and worked to find a affordable price for the services. I'll definitely be using McCullough Heating and Air Conditioning and I'll be requesting Eric for future visits.

Needed a maintenance visit and was serviced by Guillermo today. From a timely arrival through his thorough diagnosis of the issue to his resolving my issue with politeness and professionalism, Guillermo was the ultimate pro and a great ambassador for McCullough.

Josh fixed the A/C unit quickly. He diagnosed the main issue as he walked up to the unit. His expertise is outstanding. He even improved obscure elements that we didn't even know about. We want Josh to do all future maintenance on our system.

I am happy with McCullough Heating and Air. Last week, my a/c kept randomly blowing hot air. The two technicians who came to my home were very nice and professional. They answered all my questions! Eric figured out the problem quickly and with Brian’s help, my house began rapidly cooling and back to normal. Thank you!

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

We greatly appreciated the fast and efficient work that Thomas Ischy did at 10 PM to clear our clogged condensation line. He also installed a properly placed clean out port to help us avoid that problem in the future. His thoughtful and appropriate handling of the situation was also much appreciated.

We would definitely recommend McCullough heating and air to everyone. From the dispatchers (Mikayla was great! )to the technicians everyone was professional-caring and on time! Jim and Renee

Makayla was amazing! They were very knowledgeable, professional and fast! 10/10

Tech was very thorough and restored A/C quickly and alway a pleasure doing business with a locally based one.

I recently had Alex come out for a home visit, and I was really impressed. He was professional, personable, and very knowledgeable. He took the time to explain everything clearly and shared valuable insights that helped me better understand my options. It’s rare to meet someone who combines expertise with such a down-to-earth approach — highly recommend working with him.

Makayla provided our AC's annual maintenance with outstanding and professional service. She was thorough, gave us information that will prolong the life of our system which we are so grateful. We can always count on McCullough to send experienced technicians with a friendly attitude!

Beyond impressed with Dillon, Brian, Josh and everyone at McCullough Heating and Air Conditioning. Their team is incredibly knowledgeable making me feel confident and informed in the repairs we chose to have done. Far more affordable and transparent than their competitors as well. Even when trying to fix another large HVAC company's mistakes, they went above and beyond in making sure my family was taken care of and as comfortable as possible. We're for sure customers for life now and I've been singing their praises to anyone that will listen. Thank you!

Henry was fantastic and very informative. They made it the same day to replace my capacitor.

McCullough Heating & Air conditioning have been servicing our units twice a years once since 2012. They have always been professional and very efficient. I have never had an issue with them.

I was really happy that they were able to schedule an appointment on short notice, the repair was quick and reasonable, and the system was back up and running with minimal downtime.

Super impressed with Dillon and McCullough Heating and Air Conditioning. Their team is incredibly knowledgeable making me feel confident and informed in the repairs we chose to have done. Far more affordable and transparent than their competitors as well.

Another Mccoulough miracle. There were some hiccups with scheduling and I reached out to the office and they assigned Eric to be our personal repair professional. He shared his cell and basically worked around our schedule for the repair. For our inconvenience Mccoulough added another year of labor coverage. We have been with Mccoulough for decades for our 4 units. We would never use anyone else!

Great experience through our the whole Process

Writing another review because Blake & Jared’s work has to be appreciated! We had such a complex/janky setup with our previous system and they spent all day troubleshooting a replacement project- making sure every detail was correct. That gives us huge piece of mind with the repairs and yet again- McCullough sends the best people!

SHE did an absolutely thorough job. We are very satisfied with HER and McCullough. and I love that McCullough has a woman working these jobs! Excellent!

I have been using McCullough Heating and Air to provide my twice yearly maintenance for nearly 3 years. During the last 2 months I have had my unit serviced by Vlad for a drain clog and recently Jared for my annual maintenance. Both technicians did a great job and spent time servicing my unit despite that it happened to be late in the day. Both were professional in their demeanor and engaging. I would have to say the same for the past technicians who have serviced my a/c unit. I would also offer that I have been impressed with the thorough maintenance service that McCullough provides,

Makayla is awesome! We switched to McCullough from another company and are already so much happier with the customer service. We also worked with Henry in the past who came to our home to assess and repair our unit as well as signed us up for regular maintenance. I can already tell that the level of knowledge and service is so much better than our last company. I would strongly recommend.

Henry was fantastic! Knowledgeable. Polite. Tidy. Fast. Overall delightful person! Thank you Henry!!

Makayla was very informative and helpful about our problem. She gave us good tips for future prevention and also identified another potential long term issue even though that wasn't the reason we called.

Josh deserves a raise. That dude rules!

Shawn and the eval/repair team were great. 5 stars for them. Unfortunately the front office is impossible to work with. Erica in particular. After expressing to the eval team that yes, of course I would like to buy the annual membership as part of a $4k repair because it would result in net savings of $400+, when the time came to perform the repair the final payment was processed without any mention of the annual membership and savings. After this I contacted McCullough the same day of service to ask if it was possible to add the membership and receive the discount. One team member informed me that was possible, so we added the membership. The next day, Erica informed me this is not possible and that there was nothing they can do. This makes absolutely no sense to me and there was no conversation or admission of minor error that could be rectified relatively easily. So now instead of being pleased with the work, next time I need AC service it won’t be with McCullough.

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... Update: McCullough just replaced the 20+ year HVAC system in my own home and I also cannot say enough good things about that experience...from the repair gentleman, to the sales tech to the install crew and then finally the quality control inspector...3rd experience with McCullough and I cannot recommend them highly enough...

Zach did a great job explaining my situation with me , was patient with all my questions , and there was a bunch and did a thorough exam of my system which is why I called to have done . Overall very good experience with McCullough . Definitely would recommend to others . Thanks

My AC went out on a Sunday afternoon I called McCullock Monday morning, scheduled Tuesday and had it repaired and running by mid afternoon Tuesday. Recommended a new system which honestly overdue. McCullock’s staff are always great!

Dillon was an excellent service person. He found the problem, quickly fixed it, and was extremely pleasant. I would request him every time if I was able to choose the person to do the work.

My AC stopped working last night. I called McCullough and they scheduled me with a technician the same day. Makayla was amazing. She explained to me what the issue was and without hesitation she got my unit back up and running while working in the rain. I highly recommend McCullough, I think I found my go to HVAC company!

Technicians are great. The fact that McCullough gives an all-day window for the technician to arrive is so 1980-ish. Even cable companies give you a 4-hour arrival window.

Makayla came prepared to repair a Freon line that was no longer properly insulated and did an excellent job. She was efficient in the repair and did an added diagnostic check of our air conditioner at no charge. She also took the time to recommend a commercial product for use in cleaning drain lines (instead of vinegar). Overall—well done.

AC tune up was performed and technicians were great in explaining what they were going to do and listened to my questions and concerns. Very professional

No complaints here. Got same day service when my unit went out. The repairman was courteous and knowledgeable. Fixed the problem quickly and I am very happy to be cool again. That’s what I call good service.

Sean with McCoullogh came out quickly to inspect the msg in our AC. He was friendly and provided good service!

AC ln my home compressor went out. It was replaced and is working great. McCullough it made go smoothly and at a great price. We are very pleased

We feel confident about the care of our HVAC system from Mc Cullough. Zack was punctual, thorough and answered any questions we had. Highly recommend.

She was very professional and knowledgeable

Very efficient office staff who quickly arranged for last minute night repair same day as problem started. Thomas Ischy repairman was fabulous, knowledgeable, so helpful. It doesn't get any better than this!

We are very pleased with the excellent service we received from McCullough! Highly recommend them.

Henry was very nice. Showed up on time and completed work in a timely manner and explained everything very well.

Eric did a great job! He was polite and professional. He got my AC up and running again in less than 30 minutes! I highly recommend Eric at McCullough!

We are very pleased with the excellent service we received from McCullough! Highly recommend them.

Was able to get my AC fixed after hours at reasonable price same day.

I have had today the AC verges by tech Desmond Lopez best technician very profession and knowledgeable knows what to do as quickly as he can. I am Very pleased with his service

After a diagnosis for a $3000 repair by another big, reputable Austin plumbing company, Charles Bryant came to give me another bid. He didn’t find any evidence of the repair being needed! He told me the processes he’d followed to come to that conclusion, and it all made total sense. He was professional and efficient. He ended up fixing the configuration of the drain line which was also done wrong by the other company. The repair of the drain line pea trap was more than I would normally expect to pay (I own rental houses so I have too much experience with repairs), but I have absolute 100% confidence that Charles did it correctly. Worth every penny!

Vlad is the absolute best. I had a previously bad experience and the team at McCullough offered a different tech to come back for free and make it right. Vlad not only spent HOURS checking every little detail, but gave me a personal phone call explaining his recommendations because I was not able to be there in person. He offered his personal cell phone and wrote an email with details and photos. Stellar job. Dude needs a raise!

Have used McCullough for about 2 years. Have found all their technicians and office staff to be professional, dependable and trustworthy. We have systems that are about 15 yrs old. And have made a few upgrades to help eliminate mold and dust concerns we’ve noticed, over all we found McCollough to be super informative and reasonable with their recommendations to address my concerns. Specifically, our technician Jaiden Mendez was super helpful and informative.

McCullough Heating & Air Conditioning provided great service. Jaiden was friendly, explained everything clearly, and answered all my questions. My outside unit wasn’t making any noise and the fan wasn’t moving. They replaced the capacitor, contactor, and hard start kit, and the pricing was fair. They came out very quickly on a Sunday morning, which I really appreciated in the Texas summer heat. The phone staff was also kind and helpful. My AC is working again and I’ll likely use them in the future when I finally replace the whole unit.

They were very responsive and friendly!

Makayla was awesome and did a great job for me.

Arrived quickly after late day call, found and fixed issue right away, much to my relief. Great company, responsive and easy to work with. Thank you!

McCullough has come through for us once again with high-quality, thorough service. This time our tech was Jaiden M. He showed great attention to detail and worked carefully to find the issue with our A/C unit. He communicated very well, keeping me posted all along the way. Jaiden also provided full documentation of the condition of the unit and his work. I'm so glad we have a service company we can count on!

This is a new review for McCullough. They recently came by to service my AC that was having issues. Charles was prompted, thorough, and explained his finding and fix in detail. I will definitely use McCullough and team for future AC repairs. Thanks!

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.

I gathered quite a bit of information to get balanced comparisons and McCullough's offer came out ahead. Also the salesperson was extremely communicative and worked with us to get what we needed and wanted. Now 5 years later I stand by my review then, giving a 5 to Naser who came out to service our unit and make sure it could handle the excessive heat! Thanks McCullough!!!

I had some roof rats up in my attic and they did some damage up there and to the lines outside too (they chewed through to gain access to my garage and attic). And on top of that, the installation of my a/c unit was NOT done properly by the company that did it ten years ago. Henry found some issues that was causing demonstrable stress and damage to my unit that would shorten the life and gave me a reasonable quote to fix it all in one visit. Thanks!!

McCullough was quick to schedule and respond to our AC call. Easy to schedule online and Charles Bryant was checking out our unit less than 12 hours later. He found the issue, was honest and transparent, and fixed it for us quickly. Highly recommend McCullough and Charles!

Nasar did a thorough job on the A/c system He checked everything up in the attic. Had my Ac up and running again.

First time customer. Super impressed with the customer service and service guy was knowledgeable and provided great information and advice for the upkeep of my unit.

They got me up and running quickly in August.

These guys are fantastic! My husband and I are renovating an old house and when our AC stopped working, we braced ourselves for a very large unplanned expense. Dillon and his partner were able to come out the very next day and fixed the issue within 15 minutes! He saved us a ton of money & heartache, and even showed us how to prevent the issue in the future with regular maintenance. Their prices are very affordable and we will definitely be calling them again.

Naser was friendly, honest, thorough and fair. We have been very happy with McCullough and their customer service. We have had great interactions with everyone, including those answering the phones, performing the audit and installing our new system. We love that it is a family owned business and highly recommend them.

I have had today the AC verges by tech Desmond Lopez best technician very profession and knowledgeable knows what to do as quickly as he can. I am Very pleased with his service

They were very responsive and friendly!

Junior, my technician, came in and quickly tested my unit and diagnosed the problem. The day before I had a company in and they spent 3 hours. Said no heating element was out. Still no heat. Charged me $200 and left. Said some wires needed to be replaced! How wrong he was!! Junior found 3 heating elements out and said a pipe had been disconnected and never reconnected by previous tech. Junior is very knowledgable, kind and easy to understand. Thank you McCullough for your reputable, dependable company. Junior deserves a raise. 😃

The technicians were on time and assessed the problem quickly. Most of the work was completed that same day within an hour. We have two units and it was determined that one needed a full replacement. They were very helpful in offering options.

Service is outstanding. They are true to their word and do not try to sell you on things, which I appreciate.

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!

Right on time. Professional. We would use this company again and again

Wow! Didn’t think I could be this happy with an AC company. Honest, truthworthy, and upfront about pricing. Henry went above and beyond to get our AC working in time to put our kids to bed. I can’t recommend them enough - very happy customer!

My HVAC died on a Sunday night and I called McCullough based on reviews. And here’s mine: called Monday morning, got my HVAC inspected, then sales came out to talk to me to pick a new one—then it was installed on Tuesday. Amazing!! And every single interaction with McCullough employees has been exceptionally positive. Shout out to Alex who helped me pick out an AC and didn’t try to upsell me. He was a great communicator and took into account not just my home size, but my personal budget. And the installers, Richard and Arthur, were fantastic. They were friendly, respectful, and clearly care about the integrity of their work. And after working 12 hours in the heat, they left my attic, home and yard spotless. That tells you a LOT. I would give McCullough 10 stars if I could!! Thanks, guys! Appreciate you!!

Stellar company to work with. I had 3 different companies come out and felt oversold.. working with these guys has been so comforting. AC is no joke in Texas and worth having someone who cares- that was this team. Makayla was amazing. Thorough and obviously very knowledgeable, she stayed to answer all of my questions and help us weigh the decision of repair vs. replace. Then the PM Peter came out same day (within 20 mins) to eval our tricky unit and worked hard to get options. Class act!!! I signed on for the membership, that’s how much I trust them.

Tech Kyle sterling was extremely professional and nice to deal with. An asset to your company.

McCullough tech team (Shawn and Kyle) were very responsive, professional and good follow through on diagnosing and repairing the problem with my AC fast. I appreciate their service and support

Blake was awesome, super professional, did a fantastic job and gave me great tips on maintaining my AC system. Great service. Thank you.

McCullough did a fantastic job installing a new GE heat pump in our upstairs area. Richard and Arthur were respectful and courteous. Thanks McCullough!

Fast service. Quick response. The AC Tech Sean C. fixed a complicated issue that a different company caused. Sean said he could have the control board installed and AC running the same day and he came through big time and saved the day and summer. It was 103 degrees that day. Next time I am calling these guys first Sean had the part delivered and began work in under an hour. The same part that the other company said could take days to find. Sean replaced a burnt out control board then replaced other burnt out parts the other company left. Was not an easy fix . reverse engineering the previous company’s work that blew up about 5 different components/fuses. First time in 10 years my AC is quiet and doesn’t sound like the back of an airplane . no more burnt plastic smell. . No nonsense quick service! After the last company’s games it was nice to have straightforward answers and solutions. Recommend. Thanks.

Highly recommend - honest, on time, and convenient online appointment booking.

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

Josh did a great job. My A/C was struggling to keep up in the Texas heat, Josh showed up with his tools and a smile ( even though it clearly had been a very long day for him) - he methodically went through his maintenance check and eventually discovered a capacitor on its last leg ( compressor wasn’t coming on when it should have). Swapped it out and everything is working fine now. 10/10 for Josh and McCullough - highly recommend.

I have a service plan with McCullough HAC, and it is the best investment I have made for my HAC system. The AC stopped working, and with just one call, I got a next-day appointment. Matt, the technician, came right at the scheduled time, made a diagnosis, fixed the unit, and we were up and running in no time! Thanks, guys! UPDATE: Second visit, ditto on the above. Every technician is professionally trained (It shows!) Talking with confidence on the subject gives me peace of mind. New UPDATE—Summer 2025: A same-day appointment is settled! One of the benefits of having a service plan is the ability to count on professional technicians to solve our issues! Call McCulloch HAC!
