Hear From Our Customers

McCullough Heating team was great and I would highly recommend them for all HVAC installs. I was able to call them on a Tuesday, have them out by Wednesday to go over all different bids and types of systems and begin/finish the install on Thursday. When there was an issue after the install due to unknown residual damage from the Round Rock hail storm their team, specifically manager Jensen was out within an hour (during after hours) to diagnose and address the issue. Great team all around and I'm very happy with my new system.

Customer service is amazing, showed up on time and they were in and out. Definitely will be using them again!! Highly recommend to anyone that needs heating & air conditioning services.

Matthew was very nice and professional and he took care of the business went straight to the problem I really appreciate him and you guys are the best thank you very much I really appreciate it

I am so thankful to Mathew w/ McCullough arriving at my home this morning on time and assuring me my furnace is fixable and will not break the bank. I called McCullough at 7AM this morning and Mathew was at my home by 9:10 AM.

Prompt service and friendly knowledgeable folks, I’ve had them out twice now for different issues, highly recommend

First of all, Frank is great and detailed. He explained everything so I could understand. McCullough is a reliable and solid company, I will use them again. Jenson was great as well. We got a brand new furnace before the cold came.

He. Was very good

Great service as always. Very pleased.

Matt was my tech that came out. Very knowledgeable, courteous and efficient with cleaning my AC unit and checking all the fluid levels. Flushed the furnace and answered all of my questions.

Matthew Downing was an absolute pleasure to work with. He was prompt, respectful and very knowledgeable. What a great asset to the McCullough team. I’m extremely satisfied.

Matt did a good job on the AC service, and pointed out that we did not need some services I asked about as the unit is only a few years old and looks to be in good shape. No hard sell, which I appreciate.

Frank was great. Explained what he was checking, our repair options. He arrived on time.

They were timely and very knowledgeable when they came to do a tune up on my system. Really appreciate it!

I was out of town working and when I returned home the house was hot. Not, what I expected when returning home. I reached out to McCullough to schedule and they were able to have a stop and diagnose the system. The tech was courteous, knowledgeable and updated me on the upcoming changes in 2025. Had the unit repaired quickly. Noting that my unit is 20 years old and probably ready to be upgraded. So I am giving this serious consideration because of the excellent service today. Then after speaking with the sales rep, replaced my 20+ year old unit. Scheduled the day, the McCullough team/crew removed the old and installed the the new one. The crew worked efficiently, communicating clearly, and cleaned the area once complete. Overall, very satisfied, easy to work with and clarity communications was perfect. I can recommend McCullough Heating & Air Conditioning without hesitation. Updated Nov 11 2024.

A great experience! Friendly, reliable, trustworthy, skilled, mindful, courteous. if you had six stars, I would give him seven.

Fantastic experience with Jensen at McCullough. We had a run capacitor in the AC unit go out, and while other companies tried to get me to replace my entire unit (so they could sell me a new one), Jensen was able to get to the root cause of the problem and repair the unit. Honest and trustworthy, reasonable prices!

Frank was patient and answered all my questions. He was friendly and professional.

Frank with McCullough solved a problem with my condenser that I have been struggling with for the entire summer. AND was 100% honest, on time, and respectful. I would recommend McCullough to anyone with AC issues. I am old, and people take advantage of folks like me. Not Frank. He came to help. Thank you Frank!

Matt was quick and thorough. Got my AC motor replaced quickly and answered all my questions. Highly recommend.

Matthew called to confirm our appointment and arrived on time. He was friendly and professional. He diagnosed the issue quickly and promptly made the needed repairs.

First of all, Frank is great and detailed. He explained everything so I could understand. McCullough is a reliable and solid company, I will use them again

Matthew Downing is a very polite and courteous technician! He was very informative on explaining my air conditioning system. After I told him what the problem with it was he explained some of the options it could be. He immediately found the problem and fixed it! I am very pleased with his work and informative explanations! Looks like he is proud to work for McCullough and McCullough needs to be proud to have him!

I really like this company. I feel they sent a very knowledgeable and well trained technician to my house. They call when they are 30 minutes out and they communicate very well.

Price seemed very high so we are calling around to other companies

Matthew came out for a second opinion and was very professional. I would definitely call McCollough again for service based on Matthews assessment.

very good experience with our recent hvac checkup-would recommend above any other place locally here in Round Rock

Matthew was courteous and professional. He worked efficiently and took time to answer all of my question. He shared opportunities to make your system operate more efficiently. It was a pleasure to have him work our service call.

Frank was very knowledgeable and helpful. Quickly diagnosed and repaired the urgent issue with my A/C. Would recommend!

We purchased our Carrier AC, furnace and an air purifier system from McCullough Heating & Air Conditioning. I called about a week ago to schedule an appointment and it was a breeze. I also found service coupons on Facebook that I used. Great business!! We have been extremely pleased and grateful. Staff is very friendly, very customer oriented and professional. The technician was very knowledgeable and experienced and did a great job ensuring our system works great. They all are! Love it!! Thank you! P.S. I’ll never buy a Lenox again!

McCullough was timely, professional and answered all the questions we had for second opinion on our issue.

Matt was over the top trouble shooting our AC. Issues. Total professional. I’m keeping McCullough on my contact list!

The tech that showed up was not thorough in troubleshooting the issue. All he did was look at the condenser and noticed it required R22 refrigerant and backed out of the job noting that it is against EPA rules to refill the unit. That makes sense but he didn’t try to troubleshoot the issue at all. Just jumped into trying to propose a whole new unit replacement. I had another company out the same day and the issue was that the blower in the air handler needed replacement. There wasn’t even a need to add more Freon, so the R22 issue was moot. Pays to work the problem and not get hung up on details that may not pertain to the issue.

Matt was able to determine what was happening with the cooling unit right away and finalize a solution did a great job gettin it back up and running. Thank you Matt

Matt, was great. Very knowledgeable and informative. Shared best ways to be aware of possible issues and how to address them.

This was our first experience with replacing our entire home unit. From the beginning, Jensen made the whole process easy — From the proposal to the completion. He was very informative and answered and questions we had. Jaiden and Michael who installed the units were professional and courteous. I would recommend this company.

Very pleased. It was easy to set up a next-day appointment entirely online, the technician Jason was punctual, very courteous and efficient. Took under an hour to diagnose and resolve my HVAC issue.

Couldn’t be more pleased with their service. Prompt, professional and economical. Jensen worked on my a/c unit. Diagnosed problem in couple of minutes. Installed temporary part and a/c working in minutes. Did this in the rain. Came back next day with new part. Ezpz Total $149. Sweeet I highly recommend them

He was on time and inspected our air conditioning. We thought he did a great job. Would certainly like to have him come back again when needed.

Excellent staff. Quick service with follow up.

Excellent service. Our technician, Matt, was respectful of the workspace and our home. He wore boot covers inside the home without being prompted. We didn’t get the best news but our system is 24 years old, so I almost already expected we will be needing an upgrade. I appreciate the honest and straightforward advice and recommendations from Matt. Scheduling is easy, I was fortunate for a same day. Service fee and pricing is fair, communication is 10/10. Highly recommend

Franky was awesome and answered all of our questions. He was super knowledgeable and experienced in his craft.

Great service thank you.

I lift my hat to you McCullough! You provide excellent service to your customers whether it be via office staff or technicians such as Jason and Matt. Your employees are very well skilled, trustworthy and so polite. Thank you for taking care of me!

Kudos to this company. We callled and Frank came, he fixed the problem - all these in 3 hours and at the peak of summer! Can’t get this kind of service from anywhere else

Very professional and prompt service. Didn’t overcharge or try to sell me repairs I didn’t need. I will definitely use them for all my future HVAC needs

We had such a positive experience with McCullough . Their customer service was over and above. Everyone we met was professional and so helpful. Alex was so knowledgeable. All of the service staff were amazing. Can’t say enough positive things!!

Jason was on time, professional, knowledgeable, and fixed my problem in no time at all.

The technician has been working great and will hopefully

Great experience with Jason of McCullough AC. Came in listened to my problem and was able to quickly diagnosed the problem and fixed in an efficient time.

Fast reliable service, thanks

Need help installing? This is the answer: 5 stars!

Franky was friendly and gave straight forward feedback on what needs to be done to our unit

McCullough did a great job! Agent showed up early, quickly diagnosed the issue and provided a quote to fix. Repair was done very quickly! Highly recommend McCullough and will use them again if needed!

Overall great experience. I do recommend McCullough would use them again. Scheduling was easy via phone. Tech arrived within a couple hours of me calling to setup an appointment (and it was not an emergency call). Tech went over his diagnosis with me, answered my questions, quickly replaced the bad capacitor, and the A/C started running cold again shortly after.

Franky was amazing! Very knowledgeable and explained everything he was doing. He gave us advice on what we can do ongoing to prevent further issues. We will use them again for service for sure.

Jason is an excellent technician and knows what he is doing and very kind. I am 100% happy.

Most informative bid with a competitive price.

I strongly recommend Jensen Sexton of McCullough Heating and Air Conditioning. He came out the day we called; so reassuring because it was hot! He walked us through an estimate for our upstairs and downstairs units, selection, financing, installation, and quality check. He was patient and gave us lots of time, options and information. Each unit was up and running in one day. On the first evening after installation, the downstairs unit stopped working. Jensen came out at 8:00 that night and got it operational. His crew was efficient, neat, sand responsive to questions. One young man even helped me install the app for controlling the units on my phone. McCullough is a long-time Austin-based firm that is a bonified locally owned company, not bought out by private equity. You will recognize Jensen's brand of service as the kind we used to expect from a good local company.

Excellent service and communication. Made dealing with a stressful situation better.

Very informative and thoroughly tested the system.

Very fast and professional!

I arranged online for my A/C to be checked out at 8am and the tech was here by 9:15. He found the problem almost immediately. He informed me what the cost would be to fix the issue. He went and got the part and it only took him about 40 minutes to get back with the part. So now as of 10:45 I am sitting and enjoying my nice cool house. These guys are the best!! Thank you so much for the amazing service.

McCullough is an excellent company that puts its customers on a pedestal. The owners are always centering conversations around treating customers ethically and with immense respect.

Great service. Everyone is really proffessional and you can tell that they genuinely care. Highly recommend!

Jensen and his crew provided exceptional customer service! They were all extremely professional and polite. I needed a new ac unit and they were able to install one within a day with no issues and at a fair price. They are very knowledgeable and know exactly what they are doing. I definitely recommend giving them a call for any of your heating and air conditioning needs!

Great customer service! I highly recommend them.

1st class very Professional. The tech knew his job and every detail. Came on time and notified me 30 mins in advance. Quality performance. Appreciated this from the company.

It is easy to give them 5 stars for their outstanding service! I told them the issues I was having and they were at my house within an hour. Jensen was very professional and nice to deal with. He communicated with me what he was seeing and what he was doing. For some people that is not important but for me that is very important when it's possible and makes me feel much more comfortable about what is going on. I stopped at their office off Airport Road since I was passing right by it. All were friendly and nice to me and my listened to my problem and concerns. I highly recommend them from their new office in Georgetown. Great people and they knew what they were doing! Give them a call. You won't be disappointed.

They were next day service. Knowledgeable and easy to work with. Outstanding.

They came out quick and were very helpful. We will be sticking with McCullough.

Jason was very pleasant. He answered all my questions. He was very respectful. I appreciate him and his professionalism while conversating with me about my AC unit. Great company!

The guy was so servicial and he works fast thanks

Thank you Frank Garcia for an AC diagnostic and clear instructions this morning.

I have an old dying unit, but McCullough’s tech Jason, did not try to sell me a new unit, and did a good fast repair to keep me going.

I am extremely pleased with McCollough H&A and the quality of their service. Matt quickly identified the problem with my air conditioner, explained everything clearly so I understood the problems, and addressed those problems quickly and efficiently. He was friendly and professional; an excellent representative of this company. Thank you, Matt!!

Matthew Downing was an absolute pleasure to work with. He was prompt, respectful and very knowledgeable. What a great asset to the McCullough team. I’m extremely satisfied.

They do excellent work. Also if there is any problem with the work they've done, they're incredibly responsive. The teams are knowledgeable, professional, courteous, and highly skilled. We've been continuously impressed with them.

Replaced compressor motor ... came out on time and at a reasonable price.

We approached McCullough on tow occasions. The first was when our heating failed last winter and the second when our A/C had to be checked recently. Our experience was fantastic. They assigned a technician immediately. The problem analysis was thorough and details were shared very professionally. Last winter, Matthew stopped by on a late Friday evening to help us. The issue had to do with a roof replacement we had carried out. He called the roofing contractor, shared the videos that captured the defective area and helped resolve the situation. Perfect example of excellent service!

Great company Great customer service! Technician was knowledgeable and friendly! Will recommend to everyone! Thank you!

Can’t go wrong with McCullough! Highly recommend!

Jensen is amazing. Went over and beyond to fix my issue!

We were in a bind and the manager came after hours to help us; saved a lot of sweat & tears.

I’ve had a few different HVAC service providers take a look at my system and I now have a favorite. Jason was our technician and he was very thorough and transparent. The repair was straight forward and a new system wasn't needed, which was something other contractors tried to say was best. Look forward to having McCullough maintain my system going forward. Great experience!

I recently had the pleasure of having a Carrier Infinity Greenspeed heat pump furnace/air conditioner installed by Jensen and his incredible team, and I couldn't be more thrilled with the results! From start to finish, the entire process was seamless and professional. Jensen's team displayed exceptional knowledge, skill, and attention to detail, ensuring that every aspect of the installation was handled perfectly. Jensen, in particular, deserves a huge shoutout for his outstanding customer service and dedication. He patiently answered all my questions, provided valuable insights, and ensured that I felt confident in my choice. His enthusiasm and commitment to excellence are truly commendable. The new system is fantastic—efficient, quiet, and a significant upgrade from my previous setup. I highly recommend Jensen and his team to anyone in need of HVAC services. They truly exceeded my expectations and delivered an exceptional experience! I only wish I'd called them sooner!

Local company that has been in business for many yrs. Was able to be seen the nxt business day. A/C situation was resolved & a preventative maintenance was also done. Good experience

Jenson is the best. This is a local company yall. They will take care of you !!!!!!!

Jensen is an amazing technician with deep knowledge of all things HVAC

Jason was great! He was very knowledgeable & he gave us useful info! We’ll definitely have McCullough service our AC and heater!

Jason uncovered the issue that has plagued our HVAC unit for five years. Friendly efficient and thorough. Great job Thank you!

Very efficient and professional!

We had Matt and really had a great experience. He didn't try to sell us anything we didn't need and told us exactly what could and could not be done. He and his team worked hard and fast and made replacing a busted HVAC system as stress free as possible. I'll definitely be using McCullough moving forward.

Matthew Downing was an excellent technician. He was thorough and knowledgeable. Very easy to converse with. We would welcome his assistance with any future needs.

I just used McCullough Heating & Air Conditioning for the first time to have my system inspected and tuned-up. I‘m extremely impressed with the level of professionalism and politeness of their tech and the scheduler. Communication was great and the tech, Jason Rodriguez, was prompt and took time to review my system and let me know everything looked great. I signed up for the Comfort Club maintenance plan and will be using McCullough going forward.

Friendly, quick and affordable service. Will not use another HVAC company and cannot recommend enough!

Awesome job!! They rock. Highly recommend!! Very satisfied!!

Matt called and arrived as he said he would. He completed the tune-up in good time and communicated with us very well. Highly recommend!

Always can count on McCollough. Fast and reliable.

Scheduling an appointment with McCullough was easy. Service call was prompt. Matt, the tech was very efficient and communicated everything he was doing, which I appreciated very much. I rate Service by McCullough as excellent.

I recommend McCullough AC, the tech was very professional.

Matt was my tech that came out. Very knowledgeable, courteous and efficient with cleaning my AC unit and checking all the fluid levels. Flushed the furnace and answered all of my questions.

Fast, friendly, honest

Efficient, straightforward. Last company I called told me I needed to replace my A/C unit even though it was only 6 yrs old. McCullough just did a tune up, found no issues. It's working great. Trustworthy company.

Detailed routine check. Identified a few small adjustments needed on installation (new home) and made those corrections. Personable and educative.

I’m so happy with our experience with the team at McCullogh Heating and Air. Our fan motor went out on our air conditioning late Thursday evening. I was pleasantly surprised to be able to get a hold of a live agent with the dispatch team.after 9pm. They were able to schedule a technician who arrived the next day. Matthew was extremely helpful in answering our questions about some of the other components and made the repair quickly. We will definitely use McCollugh for any of our future needs and recommend them wholeheartedly.

The entire process for an annual service with McCullough was excellent. Booking online is greatly appreciated and the special pricing was even honored though the online option was not given. Matt was respectful and knowledgable about the service and answered my multiple questions about the unit in our new-build house. I highly recommend McCullough for HVAC needs!

Matt was terrific and very professional. He handled our cooling issue in a timely manner.

Had my unit go out and within 24h I had full resolution and technician Matt made sure I understood what was going on in detail. Salesman Jensen was then able to provide quotation for a new system and sat down with my wife and I at our kitchen table to talk over all options. Everyone was super pleasant and professional. Let's support these local owned business when we can.

Matt was awesome he fixed our air conditioner within minutes didn't cost us anything. It was just a loose wire and he found it exactly what he was doing and I would love to have him back if I ever needed an HVAC guy. Thank you guys so much.

I always rely on McCullough Heating and Air Conditioning for my AC service needs and their team is no exception. Matthew did an excellent job assisting me through my regular maintenance and advised me how to get the most out of my unit to keep it in prime condition. Great job!

This is a company you can trust to do an excellent job! Jensen and his team have outstanding customer service. They are very responsive, professional and they really want what is best for you. I had to replace my 17 year old HVAC system and they gave me the best price on a new system compared to the few other competitors i shopped around with. They also fixed a lot of the duct work and now the one room that never really cooled down gets cold. If you are reading this review, just call and give them a chance. You wont be disappointed. Thank you so much McCullough.

Had my annual cooling inspection with Matt today. Making sure everything is in order before another hot Texas summer. Matt is always quick, courteous and efficient when he comes out. Previously he correctly diagnosed a busted condenser coil which led to us installing a whole new HVAC system with McCullough. Straightforward, honest pricing keeps me a loyal customer of theirs with great service from Matt and others.

A great experience! Friendly, reliable, trustworthy, skilled, mindful, courteous. if you had six stars, I would give him seven.

Very quick and easy to work with.

Great job getting our units ready for the summer. Quick, courteous, and very knowledgeable of the units.

Matt arrived promptly and professional. He knows his craft and quickly diagnosed the issue with repair. He also completed an inspection of both units for future recommendations when/if needed.

Very Thorough, Very Professional. Great Service!

The technician, Matthew Downing, took great scare of our annual checkup and service. He even came back, as promised, to make some adjustments He was very professionaln and courtesy. I’d recommend him to anyone

Great service call for spring maintenance on A/C! Tech very efficient, knowledgeable, and pleasant!
