HVAC reviews in Round Rock, Texas

I had an extremely disappointing experience with Air Serv of Round Rock. Technician Chris (who I later discovered is the owner) incorrectly set my furnace transformer during his second service on 11/25/2024, which led to my furnace transformer breaking down after just 1.5 months. Despite having written documentation from another HVAC company confirming the improper settings and still being within the warranty period, Chris refused to acknowledge his mistake or issue a refund. He ignored my email inquiries and unprofessionally communicated with my tenant without authorization about the AC unit, causing additional issues and expenses. I cannot recommend a company that doesn't honor their own warranty, fails to take responsibility for their mistakes, and demonstrates such unprofessional and discourteous behavior toward customers.

Chris and his team are amazing. Ac went out on Friday. Was able to tell me what was going on and what it needed. Had me back on schedule first thing Monday and made it happen to get my ac back up and running. Really appreciate his hard work and dedication.

AC started tripping my breaker in the house and Texas Heat took over. Contacted Aire Serv last night and they sent Zion out today. Turns out the lower outside AC unit exploded and was completely dead. Zion helped setting the split unit to help compensate and air was circulating in the house. By the time he left, had a quote for a new replacement unit. Aire Serv is honestly one of those rare businesses that you find only one of in a very very long time. I cannot say enough about Chris and Doña Rattray and the wonderful team and family they have to help people in need. I have witnessed it first hand. Bless them and you could not find a more caring company or group of people.

After our Pioneer mini split malfunctioned, Chris came out and diagnosed the issue, quoted the labor to replace, and eventually returned to install the replacement unit. He did an excellent and thorough job and was extremely honest and transparent with every step of the process. Couldn't ask for a better experience and his price was competitive and affordable. Will definetely be using Chris and Aire Serv when the system needs service again.

On Monday, May 19th, AireServ was contacted to investigate why our air conditioning system was not cooling. A technician was dispatched to our home. He accessed the attic and determined that the condensate line needed to be flushed with nitrogen. After performing the flush, he said the system should now function correctly. The technician was respectful and courteous. I later learned he was a high school student working independently on HVAC issues.

However, within hours, it became clear the AC was still not working. We called AireServ again, and the same technician returned that day. His first question was, “Did you check the outside unit?” I explained that I had called for professional help. He then proposed several costly services as possible causes. Notably, he inspected the outdoor unit—something he had not done initially—and replaced the capacitor without first seeking my consent. He informed me afterward that the replacement had already been completed and handed me the old part. Although I accepted it, I was uncomfortable with the lack of communication and authorization. I declined further services and informed AireServ I would be seeking a second opinion.

AireServ later refunded the nitrogen flush, acknowledging it hadn’t resolved the issue. Unfortunately, what followed required further attention.

The day after the visit, I discovered a leak under the sink in my master bathroom. This caused water damage to stored items (makeup, hair products) and the cabinetry. I had no reason to link it to the HVAC service and called a handyman, who stopped the leak.

On Sunday, June 8th, while we were at church, a large section of our dining room ceiling—approximately six feet long—collapsed due to water damage. That morning, the ceiling appeared fine. Thinking it was a roof issue, I called our roofer. He found no roof problems but identified a broken or disconnected HVAC pipe in the attic. He provided photo evidence and recommended contacting AireServ.

A different technician from AireServ responded (Father of first technicians baby mama). He inspected the attic and quickly dismissed any connection between the nitrogen flush and the damage, claiming a properly glued line wouldn’t be affected. However, multiple HVAC professionals have since told me this type of failure is a known risk, and reputable companies take responsibility when such damage occurs. One highly regarded local technician confidently stated the flush caused the damage and that any responsible company should handle the resulting repairs.

When I mentioned the earlier sink leak, the technician seemed surprised and mentioned that some customers have reported residue in sinks after a nitrogen flush—information we were never given. Had we known, we may have recognized the connection sooner.

He also offered conflicting explanations—initially blaming poor insulation and condensation, then admitting the pipe had simply come unglued. He repaired it, and we’ve had no further leaking since. However, the damage to our ceiling, cabinetry, and personal belongings remains unresolved.

Throughout our interaction, the technician deflected responsibility, referenced the previous tech’s version of events, and made unrelated comments about other customers. He also criticized the company that originally installed our HVAC system while claiming he “doesn’t speak negatively about other companies.”

As a widow and mother of two young children, I feel disrespected and taken advantage of. AireServ’s refusal to acknowledge or address the damage caused during their service is deeply disappointing. Based on expert opinion, the nitrogen flush likely compromised our system and led to the resulting damage. At a minimum, we expected acknowledgment and compensation. Instead, when I followed up with the company (and spoke to the wife of the second technician- who was also the mother of the first technicians baby mama), I was told, “There is nothing further we can do to help you,” while blame continued to be shifted elsewhere.

I highly recommend against this company.

I was referred to Aire Serv of Round Rock and I am really glad I was. The service and professionalism was outstanding. I had an issue with my mini-split and at first I had a different company come out -- they couldn't find the leak and gave me a massive estimate. So I needed to get a second opinion. That's when Chris from Aire Serv came to my house just a couple hours after I called. He found the leak right away, and got my mini-split back up and running at a fair price. I was 100% satisfied and totally recommend them!

Had great, timely service. Very friendly and knowledgeable about hvac. Came on a Sunday when couldn't get anyone else!!

I highly recommend working with Aire Serv. Starting with Dona on the phone who kindly and calmly helped me troubleshoot heating issues and set up an appointment that was convenient for my family. Then, we received a note that they were on their way, and Chris and Zion arrived on time.

During the appointment, Chris was extremely knowledgeable and efficient in evaluating our HVAC system after our heat pump stopped working. He provided a detailed breakdown estimate and helped me understand each part of the estimate including how to plan for the expenses rather than needing to fix anything today. It turned out we can keep using our gas furnace now instead of needing to replace the old heat pump now. He provided the information with zero sales pressure and educated me on much more about our system than the part that was broken.

It was a phenomenal experience as new homeowners navigating through old systems with Chris and Aire Serv. We’ve found our local HVAC experts with Aire Serv, and plan to work with them for multiple future projects in the house!

AC went out on Saturday evening before Father’s Day. SUPER nice and didn’t charge an extra fee for weekend/holiday. Came in and diagnosed the issue very quickly. Very knowledgeable and recommended a great thermostat for us. Hopefully this will be our new go-to company from now on!

The whole team at AireServ Round Rock really go above and beyond!
Chris and Zion initially came out in October 2023 to diagnose our AC that wasn't cooling properly (warm air was coming out of vents, and it took hours to get to the desired temp). A cleaning spray was applied to the dirty coils as a stop gap solution, and we were quoted a service to fully clean the coils and furnace as well as a quote for a whole new AC system. We were about to leave for our honeymoon, so as a courtesy, we were not charged for the diagnostic and cleaning spray application.
That was good business as I remembered the company when our AC stopped cooling at all last week, almost 2 years later. I had a few companies out to diagnose the issue and quote us on a new AC system. Chris honored our initial quote from 2023, even on a more expensive inverter AC system as opposed to a traditional one. The quote also included all new refrigerant line installation as well as post-installation duct cleaning throughout our home.
In crisis mode, we bought a portable AC unit to get us through the next two nights, which Chris kindly set up for us and then purchased from us to use as a company loaner.
Doña has always been a calming presence to speak to and even remembered us from 2023. She also did additional research for me on financing options.
Zion completed the duct cleaning a few days after the new system was installed.
Chris is incredibly trustworthy and hardworking, and we know he will not cut corners. He knew from 2023 the issues that we inherited, starting with a bad installation all around.
We're happy with our new, more energy-efficient inverter system as an eco-conscious couple! Other companies who quoted did not even offer us or educate us on this option.

Very friendly and professional service. Did a great job and took care of everything right the first time.

We had Chris out recently to take a look at our A/C because the house was getting unusually hot. He was great—on time, professional, and quickly diagnosed the issue. He explained everything clearly and had us cooling again in no time. Highly recommend!

Called AireServ at 11pm when I got home and found out my AC is not turning on. AireServ picked up my call right away but told me they couldn’t send a tech out immediately. They said they will send someone out first thing in the morning (7-8am) without service call fee. Chris arrived at 8am and repaired the AC for me. I needed the gas line relocated for me so it’s not blocking the access to the AC unit and Chris did it and made sure everything is up to code. He then installed a new blower motor fan and the bracket, reignited my gas water heater, and cleaned everything up for me. He’s punctual and professional! I would use this company again when I am not tied down to my home warranty company!

Air Serv did a great job with maintenance on our older hvac unit. We had problems in past years because Sears installed a bigger unit than we needed. Previously 2 different companies tried to sell us a new unit. Chris, who has 30 years experience, gave us tips on how to make things work better with the unit we have. Turns out it works fine but there are somethings we need to do differently; and somethings that we might need to do if we have issues in the future. All this without requiring a new unit we can't afford. We had tried to self-install a mini-split and botched the job. Chris reinstalled the Della mini-split at a much better rate than other places. Now, we have a working central HVAC that has had seasonal maintenance for the upcoming winter and a properly installed back-up mini-split in case our main unit gets too old. Thanks, Chris and Air Serv.

I was very impressed with how quickly Chris and Doña were able to respond to our HVAC going out. Chris was able to identify the issue fast and repair same day while still having to pick up parts that needed replacing. He was very informative and transparent with his process and really appreciated him not trying to upcharge extra unnecessary services, unlike other companies I’ve had service my home in the past. The customer service and expertise of Chris and Doña at Aire Serv turned me into a forever customer of theirs.

My AC was not working properly and I had already had another AC company look at it but it was still not functioning correctly so I reached out to Aire Serv for a second opinion. Chris was able to service it and get it running more efficiently in no time! He was super knowledgeable, and explained things to me in detail which was much appreciated. I would highly recommend this AC company, not only do they come with years of experience but they are reasonably priced as well!

My air-conditioner started acting up and wasn’t cooling. As a hot-flashing menopausal woman during these 100 plus degree days this was intolerable and needed to be fixed ASAP, for the safety of everyone around. I reached out to Aireserve, because of my positive experience with them in the past. Chris was to my home within a few hours of my call, running up and down my stairs from the attic to my unit outside, diagnosing and working on this problem. I appreciate his urgency as well as him taking to the time to clearly explain the problems and the options I had. By the time he was done the temps in my home were at a survivable temp and my kids felt safe to come home and be around me. Thank you Chris and Aireserve. You may have saved this customer from spontaneous combustion as well as preserving this families ability to be around this mom.

Chris was amazing and fixed an issue that long plagued us. An issue other hvac companies could not figure out. Thank you so much for coming out and helping get cold air back for us!

My air conditioner died in the spring, which meant that I had time to shop around and get multiple quotes. I went with Aire Serv because Chris was extremely helpful and and knowledgeable. He explained my options and answered all my questions, and I didn't feel pushed toward any particular option. I ultimately felt comfortable going with a high efficiency inverter heat pump system from Goodman. He was able to start the work earlier than I expected and he finished early. The work looks great (I appreciate Chris adding in the extra surge protection), and I'm enjoying having air conditioning again!

In a panic, I called Aire Serve Round Rock. I am a recording studio owner in the country north of Liberty Hill, Texas. In the beginning of the terrible week of ice, snow, and record low temps, my heating unit...2 Mitsubishi type wall units...had stopped working and it was COLD. I have an expensive baby grand piano among other sensitive equipment and I was, to say the least, in a total panic.

I searched for a local maintenance company that were familiar with my system and discovered a new business in Liberty Hill...

I called them and spoke to a wonderful lady who, in turn, put me in touch with her husband. He was booked and unable to get to me for some hours. Unlike so many, he actually took the time to walk me through the process that fe felt would fix the issue. I did exactly what he told me to do and soon had heat.

Since then, because of the extreme weather event we have just experiences, I have given their information to anyone that I thought might need their help.

On a personal level, I will never call anyone else for any heating or air conditioning work. If there were ten stars I’d give ten and wish there were five more.

Aire Serv Round Rock, to use the vernacular I am so used to, totally ROCKS..

I don't usually expect to be impressed when I need AC service, but I sure was this time. I have had a lot of different AC companies come to my house, because it seems like there is always an issue with each one. This time, I called Aire Serv because my AC unit stopped blowing cold air shortly after I got home. The unit outside was not working at all and making an obnoxious noise. Chris (who I later learned is the owner) was at my house within a couple of hours, even though it was after 5pm. It is obvious that Chris has a lot of experience and knowledge in this field and focuses on providing great service. He was very friendly and transparent and was able to diagnose and repair the problem quickly. My unit was back to pumping cold air in less than half an hour of his arrival, and the pricing was better than similar service calls I have had in the past. Every interaction I had with this company, from Tonya who took the call, to Chris who serviced the unit, to the price I was charged, was a positive experience. I think I can finally stop bouncing around looking for a competent, reliable, and honest AC company.
