Henry was great! by Ben on 2/15/2024
 

Had yet another wonderful experience with McCullough in the form of a follow up inspection conducted by Henry Harris. He was extremely professional, clearly very knowledgeable and experienced, and incredibly thorough with his examination and some subsequent improvements. I could not be more pleased with the whole experience!

Excellent Customer Service! by J. Mancillas on 2/15/2024
 

The technician Desmond Lopez was courteous and professional. I called McCullough regarding the heater making loud noises during the cold days in January. Desmond did the initial diagnosis and with his manager agreed that the motor needed to be replaced in the air handler. He returned at a later date to replace the motor and completed the work efficiently. Desmond is very knowledgeable with heat pumps and answered all my questions.
Thank you to Desmond for sharing your knowledge and a job well done!

Kyle was great by EHG on 2/14/2024
 

Even though the news on my A/C wasn’t what I wanted to hear, Kyle tried his hardest to get my unit working. It was much appreciated. Thank you

Fixed my hvac heating issue by Thilak Vaidhyalingam on 2/11/2024
 

Deandre Rodriguez spent more time and checked thoroughly and fixed the issue. I was really happy with his work and knowledge . He inspected the furnace, thermostat and compressor and then diagnosed correctly

Great experience by Subir on 2/10/2024
 

Junior de Jesus was great, he spotted the issue right away, addressed it, gave me great advice, didn't try to overcharge or upsell me. Thank you to the team.

Great service, always! by Nicholas B. on 2/5/2024
 

My latest experience with McCullough was great, as always. The technician, Alonzo Olivas, was courteous and professional, did his work efficiently and left me perfectly confident that my A/C system is well maintained and in good hands.
This company is very responsive and has excellent customer service.
Thank you!

HVAC Annual Maintenance by Tim Young on 2/4/2024
 

I had McCullough out for the annual maintenance on my HVAC units this January. The technician, Henry Harris, was timely, cleaned up after the work was complete, did a prompt and thorough job, and explained all his findings and adjustments. Very professional, knowledgeable, and courteous. I highly commend him for a job well done.

A/C Service by David Ramirez on 2/3/2024
 

DeAndre Rodriguez did an excellent job on my air conditioning unit at my residence today. He was very professional from start to finish and also very courteous. Thank you DeAndrea and the McCullough Team! I recommend this fine establishment.

Outstanding service! by Maria Dallman on 1/30/2024
 

Dillon Revells it's an outstanding technician specialist, problem solver! He is extremely knowledgeable and finds the solution right away. He's performance is impecable in every sense of the word.
He fixed an ongoing problem that I've been having for years and was able to assess the situation right away on his first visit in 10 minutes, following up with a prompt appointment to fix the issue since he needed to order the new equipment needed to fix it.
He's not only very courteous, he's polite, caring and kind. He is truly an Angel!
This company has been very proactive and efficient.
I highly recommend them!

Great quality service by Karissa on 1/27/2024
 

They were quick to send someone out and James was friendly and answered all my questions! Was transparent about what needed to be done and what should be done in the future. Highly recommend James and the team!!!!!!!!!!!!!!!!!!!

High quality customer service, efficient and fair priced by Sam on 1/23/2024
 

My old AC of 13 years broke and I had to replace the whole system. McCullough was very efficient from diagnosing the issue to sending a proposal and installing the new AC in a timely manner. Every crew member was diligent, thoughtful and professional. I highly recommend McCullough for you AC system!

EJ Pittaway was especially helpful after finding out that the digital temperature display did not work with my wifi network. He ordered a new router to troubleshoot the issue and made sure that I was not experiencing the issue after the QC walkthrough. He was professional, on time and thoughtful about the customer even beyond the service that was expected.

Lack of heat issue by Bob Green on 1/20/2024
 

Technicians arrived in a timely fashion. They were knowledgeable and polite. The problem was a conduit that had come loose, and the attic was being heated. Conduit was retaped and sealed. The 4” whole-unit filter was also replaced.

Without Heat During the Freeze by Loera Family on 1/19/2024
 

Our heat was not working properly and even on emergency heat the system wasn’t heating past 67 degrees. Alonzo came a checked out our system thoroughly and informed us of a setting adjustment he was able to make to improve the heat as well as a part that needed replacement. Even though we haven’t scheduled the part replacement yet, our home is a lot warmer and holding a better temperature thanks to Alonzo.

Quick. Fair. by Walter on 1/19/2024
 

Heat pump went out and Dillon Revels was quick to the scene on that same day! Diagnosed a fried board on outside unit. Ordered part and two days later installed and running great. Great service all around.

Superb service! by Melanie on 1/16/2024
 

Kyle was quick to find the issue with my furnace, and very knowledgeable about upkeep and maintenance. He helped to save me money, and gave me piece of mind to make it through the latest freeze. Thank you, Kyle!

Much appreciated by Natalie W. on 1/16/2024
 

Junior De Jesus did my twice-annual HVAC inspection. That went fine. But what I really appreciated was his advice about my gas fireplace, which I have been afraid to use for the 21 years I have been in my house. He helped me realize that I just need a quick chimney and gas leak inspection. And then I will not need to stress about the power grid going down. Am going to do that this week. Thank you, Junior!

Fabulous Service - James Sanchez is the BEST! by Sarah Schattman on 1/15/2024
 

I had a handyman install a new bathroom heater & exhaust fan almost a year ago. He left the bathroom open to the attic and insulation fell into the bathroom regularly. I was afraid to run the heater since it might suck insulation into the fan and start a fire or burn out the motor.

Finally, since McCullough had done an excellent job installing my new HVAC system and insulation prior to Snowmageddon, I thought - call them. James Sanchez came and checked out the situation, climbed in the attic, took lots of pictures and derived a solution. The device had not been properly vented when initially installed, so James remedied that, enclosed the unit so insulation would not be sucked in every time I tried to use the heater or fan and most importantly, sealed off the unit from the open attic. When I look up into the fan, I can no longer see into the attic. This was all achieved two days prior to the January 14-16, 2024 winter storm. I can warm up my bathroom prior to taking a shower! Totally blissed out by a warm bathroom in winter - it's the little things.

As for James Sanchez himself, you will look high and low before you find a more thoughtful, considerate and competent HVAC technician. I am willing to bet that man could walk across Town Lake and not get the soles of his feet wet. Thank you, James!

Great experience!!! by Chris, Owner of Legacy Custom Built Inc. on 1/15/2024
 

Great experience all around! The service specialist, Dereck, very friendly and knowledgeable. They were able to assess the situation and help get things back on track. Quick to respond and come out which was super helpful with the impending freeze.

Service worth a good review by Abe on 1/14/2024
 

I called McCullough because they work on Carrier systems. A year earlier they replaced the fan in the main unit which was still under warranty. AC installer changed their name and stopped taking calls which told me a lot. McCullough replaced the grinding fan and I signed up for the semi annual service. Much later the fan started to grind again and was off balance. I called them out and the same day they replaced the fan again. It was so close to being out of service warranty but they helped me out. Now with yet another freeze the heater is working great and quietly. They run a good operations with great technicians.

Furnace fixed just before cold weather by Ed Black on 1/12/2024
 

It was a tough diagnosis, but James Sanchez and the McCullough team were professional and made sure we were ready for the winter. Great company and team. We will continue to use these guys

Great company and team by T M on 1/10/2024
 

McCullough installed our HVAC about a year and a half ago. We were so impressed with their customer service, quality and pricing, that we always recommend them. This year, we had a small issue and Dereck came out, diagnosed the issue and had it fixed in no time! Great service.

Great service by Jamie on 1/8/2024
 

I had a great experience with Mitchell. He diagnosed my problem, had to go get the part from the warehouse, and was back in an hour to complete the repair.

Outstanding Service - Always by Carl E on 1/6/2024
 

Ever since McCullough installed our new HVACs, their warranty service and troubleshooting for minor adjustments have been excellent. Our latest service, by Junior dJ, was wonderful. Not only did he make some air current adjustments, he explained everything clearly to help us understand our thermostat settings better. Not only that, but their techs always respond to our requests promptly. All companies could learn from McCullough’s model about treating customers as a priority.

Don't waste your time by Yaron on 1/5/2024
 

The technicians were great, professional and knowledgeable.
The company prices are ridiculous comparing to any other contractor.
Definitely do not recommend.
Additionally the office communication is horrible and you can forget speaking with anyone but costumer service representative.

Profesional and trustworthy service by CM on 12/28/2023
 

Matt is a pro! From diagnosis to complete fixing of an issue, McCulloch and its professional team are the company to trust with HAC issues. The back office and CS support are excellent. Their annual preventive service contract proves to be a good thing to have.

Service Call by Kelly Houston on 12/21/2023
 

Nick did a great job analyzing our Heat Pump problem and electronic issues. McCullogh was very fair on their pricing and effective at taking care of our problem.

Above and beyond customer service! by Happy customer on 12/19/2023
 

Derek came for out to perform the winter inspection on our system. Part of the service includes replacing the air filter which I usually have on hand. This time, however, I did not but Derek took care of it by getting the correct size from McCullough and replacing it for me. That’s above and beyond service! He also inspected the duct work to make sure all was intact after a new roof installation. I could not be more pleased with Derek or McCullough. Thank you Derek!

Great company! by MH on 12/18/2023
 

They installed a new system which was done very professionally with the site cleaned up before they left, and the maintenance program is done on schedule when required. Very satisfied!! Thank you

Fast response, great service by Chris D. on 12/18/2023
 

I have used McCullough before and have been pleased with the system they installed. This time I had an issue with a system that was old and on life support. I called them, and secured a same day appointment. Matt was the tech, and he was friendly, and fixed the system quickly. Very pleased.

Fast diagnosis, quick resolution by Adam on 12/16/2023
 

DeAndre Rodriguez diagnosed our busted blower motor instantly and was out the following day with the part. He had a very honest and chill vibe I could instantly trust. We had our system installed in late 2019 by McCullough and had bought the coolcare 10 year labor protection plan with the installation. Between that labor plan, the remaining manufacturer warranty, and the comfort club membership for regular maintenance, the blower was fixed free of any additional charge in less than 24 hours. I don’t think it gets better than that!

Great experience by Jenn Ritchie on 12/14/2023
 

I’ve had a few great experiences with McCullough since June. Everyone of them has been fantastic. Our first tech taught us how to maintain our central system (we had no idea), second did a quick update when our system went out and most recently Matt made sure we were all set to go for winter. Really glad these folks are our HVAC team

Did a Thorough Job by Caleb on 12/13/2023
 

My tech did a thorough job. He was respectful, courteous and knowledgeable about the service he provided. He also provided a break down report on what service he performed in an understandable way. Would highly recommend!

Highly recommend by ECR on 12/11/2023

HVAC Service Call by Vicky on 12/10/2023
 

Appreciate the technician, Frank, who came out to service the HVAC system. He got to work immediately and finished in record time. He also stopped to suggest adding this system onto the existing service contract on the two HVAC units purchased through McCullough, to save me $ on the service call. Thank you, Frank!

Excellent work & Customer Service by Daniel Y on 12/8/2023
 

We've been in our home for over 20 years and McCullough has been our A/C go to folks. Our system was throwing out some errors and McCullough sent out our favorite rep James Sanchez to troubleshoot it. He quickly diagnosed the issue and ordered the needed parts. He was back within a few days and got it all squared away! James is professional and always keeps his hair combed ??. Merry Christmas guys! Keep up the good work!

Thorough and Professional by Saucedo on 12/8/2023
 

The service I received from Matthew was thorough, prompt (although an 8-hour window is awkward), helpful, and very professional. I recommend working with this company and look forward to them as my go to HVAC company moving forward.

Maintenance service great; whole day window for arrival stinks by Alan on 12/3/2023
 

Very happy with Nick who did our annual heating maintenance. McCullough has to start scheduling better than a whole day window when the service man can come. Even cable companies don't make you commit to a whole day window for your appointment anymore.

McCullough is great and so was Jeff by Reagan on 12/1/2023
 

We’ve been very happy with the service and advice McCullough’s offers us right from the beginning when we needed a new hvac system in our home. This last time Jeff was our service man. He was prompt, polite, and thorough!

Great service as always by Bill on 12/1/2023
 

I’ve used MCCullough Heating & Air for years and am very pleased with their service. EJ came by this week to do the annual furnace inspection and was on time, professional and helpful with some suggestions to my furnace. Highly recommend these guys for your HVAC needs.

Repair for Rental Property by Phil W on 11/30/2023
 

Called due to heat not working at my rental property. The previous week another HVAC company was not able to identify the issue.I was able to get same day appointment. Technician identified the problem, and ordered the part. Came the following day and fixed the unit. Was able to pay online. Great communications via text and phone. Will use again!

Joel was amazing! by Dom on 11/28/2023
 

Called these guys for a second opinion and they were honest and went above and beyond. Will use again in the future - thanks for the great service, y’all are the best.

Excellent service by Tom on 11/24/2023
 

I’ve used McCullough for several years. They are Always timely, professional, and reasonably priced. Geoff has been the technician for recent visits and he is outstanding. He takes the time to explain what he’s doing, any issues and a choice of fair options.

Excellent customer service! by Lore H. on 11/24/2023
 

The technician that came out was Jeff Anderson. He was professional, caring, and helpful. We belong to the comfort club.
It brings much relief that our heater/ air conditioning is in good shape every season. I totally recommend this business. I have found them to be honest, caring and consistent for many years.

Well done Matt! Thank you ?? by K Fisher on 11/5/2023
 

AC went out at 6pm on Saturday. I called and Matt was at my house within the hour. Luckily, it was not a major issue. Matt made the repair quickly and also fixed up some loose seals. He was done in less than an hour. He even advised me of tepairs that would need to be made down the road, though not urgent at this time. Very professional, very courteous and smiling even though it was Saturday night and he's working late. Price for repair was extremely reasonable. I will be using him for all my HVAC needs!
