HVAC reviews in Houston, Texas

Their service was great. I was having high humidity issues with my AC unit and making it really warm in the house. They helped me fixed this issue and gave me more refrigerant and gave me helpful recommendations to keep my house cool. Thank you

Kerry, the service tech was very professional as always. He left us with a peace of mind. He was able to determine the root of the problem.

Very prompt and they call when they are on there way. No hidden charges. What they quote is what you pay. Office personnel very courteous and friendly. Prices are lower than most skilled companies charge. J.D. is probably the best ac tech around. Gets it right the first time and the installation crew did a great job also.

I had a great experience with technician Keri on our A/C service. He was punctual, professional, and quickly diagnosed the issue. The repair was done efficiently, and everything is working perfectly now. Highly recommend for anyone needing reliable A/C work

Had a great experience with Big Tex technician concerning troubleshooting our dryer vent discharge. Thanks to the knowledge the technician shared and to his previous experience, we were able to pinpoint the exact issue with our system. I would highly recommend Big Tex to anyone and everyone I meet in the future!!! Job well done 👍

Extremely Unprofessional and Inappropriate Service Experience

A technician came out for a service call and was rude from the start, making condescending remarks about an issue with the thermostat and implying we should “already know” how to operate it.

More concerning, he behaved in an unprofessional and inappropriate manner — making unwelcome personal comments about my appearance, telling me I am “better when I smile,” and even going so far as to touch and rub my arm without consent.

This behavior made me feel unsafe and extremely uncomfortable in my own home. If this individual is ever assigned to return, I will contact the police and seek a restraining order.

No customer should have to experience this kind of conduct from a service professional.

The technician was professional, courteous, personable and helpful. He explained how to care for my system and made suggestions for preventing future problems. I was pleased with his customer focus, technical ability and ability to effectively resolve my issues.
He represented the company
well with his expertse!! Truly a job well done! 👏

They showed up the days they promised. Called ahead of time to notify when service was on the way. Issue A/C kept running when thermostat set at 75 but thermostat only reached 77 degrees. 1st visit discovered Freon was low. Discovered that the valve stem was loose causing lost of Freon. Lowest Temperature still just 77 on thermostat with a/c setting at 70. 2nd visit Technician discovered no insulation behind thermostat, sprayed insulation in hole where wiring coming in for thermostat to prevent heat from walls to enter the back of thermostat. Called office to report that the lowest temperature still 77 degrees when a/c is setting is 72 degrees. Office suggested to reboot. Which is powering down the furnace switch in attic and powering down A/C unit outside. Scheduled appointment but if after powering down works to notify. The lowest temperature got down to 75 degrees with a/c setting at 70 degrees. Service technician came the third time but had no solution and is going to report to Supervisor to see what they can resolve. 4th visit Technician specialist came yesterday unannounced just rang doorbell. Was up and down attic and outside. States he made adjustments that should fix it but we have our thermostat at 72 degrees all day today. The thermostat temperature is 76/77 degrees. Our thermometer in the family room is at 77-78 degrees. So it still not cooling down our house with the A/C unit running all day long all summer. 5th visit same technician specialist came air conditioning running all day and house just cooling to 76 degrees. He reported that air out of register was 56.8 but house can’t cool any lower because it’s to hot outside. So he still haven’t found a solution and says everything working properly. So I guess our new construction home doesn’t have the capability to cool our house below 78-75 degrees even if we set are thermostat to 72 degrees. Doesn’t make sense to me and I’m not going to except that nothing is wrong. If the air is 56.8 degrees in the register and my house is just 76-78 degrees when my thermostat setting is at 72 then that tells me something is definitely wrong. Maybe the tonnage is to small or the insulation is not adequate, or a combination of both. I expressed this to the technician but he said no everything is designed by the engineers and it is correct. Im getting hot 🥵 and frustrated. Does anyone have any suggestions to make our house cool and comfortable?

The workmanship from Big Tex has been nothing short of unacceptable. After installation, they had to return to correct their own mistakes, including adding a plenum and splash guard and rerouting HVAC ducting that should have been properly designed and implemented from the beginning. This raises serious questions about quality control and oversight during construction.

Even more troubling is that Big Tex required homeowners to sign a waiver releasing them of any responsibility if the A/C is set below a certain temperature. This deflects accountability and suggests the system is not capable of functioning properly under normal conditions—a red flag for both safety and compliance.

My family and I, as well as many of our neighbors, are now experiencing condensation issues related to HVAC. This isn’t just an isolated problem; it’s systemic. In fact, we previously leased a home in another community and had to move out due to mold caused by HVAC issues—and we’re seeing signs of similar problems now. The AC installer was Also Big Tex! Just a reminder my home is only 3 years old and they installed this and Castle Rock allowed it. There was no accountability at all from our Builder.

BigTex AC installed my AC in 2023, and ever since then they’ve been excellent with service and support. Most recently, the technician came out to change my filters and check the unit — he was great! Friendly, professional, and very knowledgeable. He not only made sure the system was running perfectly but also gave me helpful advice on how to keep my AC running healthy for the long term. From installation to ongoing maintenance, BigTex AC has been reliable, responsive, and a pleasure to work with. Highly recommend them!

Did a great job on diagnosing and fixing the problem. They are honest and fairly priced! I would highly recommend. Another company tried to charge my 4x the amount for the same work.

I had a great experience working with your company. Tech that came out was very friendly and explained what he was doing to get me back up and running. Thanks so much.

The tech handled himself as a true professional. He serviced and took his time on my system. Checked the ac and heat. Replaced my filter and explained what was done. Thumbs up for a job WELL DONE !! Thank You

Our AC started to blow warm air during a late Saturday afternoon. We were worried there would be no help over the weekend. To our surprise, Big Tex Air was available to repair our unit the same day. Technician was professional and knowledgeable. Our system was repaired to satisfaction. Thank you for helping us on a weekend evening. 😁

First time using big Tex, went from a reference from a co-worker. They didn't disappoint. David the tech was awesome and got things up a running even working up in my attic with a temp of 137 degrees. Pricing on point service for Mary and the company was awesome. I would highly recommend. Been using another company from many years but they were bought by a bigger company. Had to call them on an easy job, I had an idea of what it should have cost, but they doubled that easy. So the research began to find a better AC company that still cares and not price gouge you. Very pleased. Thank y'all.

Keri is an excellent technician. Does a great job. Always takes time to talk to me about preventative measures for me to keep my unit to last longer

Our technician was very courteous and professional. He was sure to put booties
On his shoes prior to entering our residence and made us feel confident that he inspected our unit properly. He also took the time
To explain entering thoroughly and even congratulated us on the way we have been maintaining our unit. Nicely done!

The technician arrived at the scheduled time. He quickly diagnosed and fixed the problem.

Big Tex Air Conditioning is reliable and provides experienced, honest service. I've been a satisfied customer for about 20 years!

⭐ 0 Star if I could 11/9/2025 – Unprofessional, Misleading, and Untrustworthy

Our experience with Big Tex Air Conditioning Inc. has been overwhelmingly negative. For months we struggled with serious HVAC issues in our home, yet the service we received was consistently delayed, dismissive, and unprofessional.

Most concerning, Big Tex Air Conditioning provided HVAC data to the builder but refused to provide it to us—the homeowner. The limited information they did share was manipulated and incomplete, directly contradicting the daily temperature and humidity photos we documented ourselves. Their actions show a clear lack of transparency and raise serious concerns about the accuracy of their assessments.

After everything we’ve gone through, it’s obvious that accountability, honesty, and customer care are not priorities for this company. I strongly recommend avoiding Big Tex Air Conditioning Inc. and choosing a provider that values integrity and treats homeowners with respect.

Replied to my warranty request quickly. Answered the phone quickly. Even Answered an email question I sent quickly. So far everything i have experienced with them has been top notch 👌 👏. Thank you for being a reputable company.

The company was supposed to show up on Thursday and did not. So they called and said they’d come Friday after 12. At 5:15pm no one had called or showed up so I called back and they said they tech was in route. At 730 pm they finally showed up. Very disappointing! However the tech was the first person to figure out what was wrong with our AC after we’ve had FOUR different companies come and say nothing was wrong.
