HVAC reviews in Katy, Texas

I had an excellent experience! Financing was easy. The technician was courteous, on time, and responsive. Everything was explained clearly. I recommend this company to anyone in the Houston/Katy an surrounding area.

This is a very nice company to work with. The guy is very knowledgeable and considerate. I had a last minute situation and he rescheduled things so that I could take care of things.

The service was amazing !! Moved quick on a timely manner got my a/c from not blowing to cold ac and I’m loving it highly recommend!!

I had to get a whole new AC unit installed,and it was looking very expensive from the calls I had made until I called Done Deal they gave me a great price as well as came right in and got the job did quicker than I thought I recommend these guys to anybody they are the best thanks a million❤️

Great experience, upgraded from 3 tons to 3.5 tons. We replaced our air conditioner unit and added gas furnace and coil from Carrier, Mr Ede, after the first call, next day he brought the unit and install at a reasonable price with professional installers, AC is working great now, thank you for yourbservice

My home ac went out all of a sudden in this texas heat so i went to my brothers at done deal and they offered me same day service with a much better price than anyone around and their service was very professional and better and faster than anyone ive worked with before. Thankyou guys!

Great company. I used this company for my Air Conditioning system to be repaired. They were very kind respectful and knowledgeable on my issue. They worked efficiently and carefully to fix my issue. The explained to me my issue and what needed to be done before they fixed it so that I can understand the cause and effects of what happened to my AC. I also referred my sister to get her Air Conditioning system fixed when necessary!

Done Deal A/C & Heating Katy provided great value and were professional from start to finish. What really stood out was their responsiveness even after the installation — they followed up quickly and addressed post-installation issues without hesitation. Reliable, fair, and easy to work with.

I can see why they’re the best in Katy. They really do offer the cheapest price in town. Everyone else was charging me an arm and a leg. In this economy, even a few bucks can add up and be expensive. But nevertheless, their tech guy came out, gave me a quote (which beat the others) and installed a brand new AC unit the same day. I couldn’t be happier. I highly recommend them if your AC is out or not working.

I can’t say enough great things about this HVAC company. From the moment I called, their team was professional, responsive, and genuinely helpful. The technician arrived right on time, explained everything clearly, and took the time to answer all my questions without rushing.
The work was done efficiently and with great attention to detail. It’s clear they take pride in their craftsmanship and care about doing the job right the first time. My system is running better than ever, and the difference was noticeable immediately.
What really sets them apart is their honesty and customer service- no pressure, no upselling, just straightforward, high-quality work. If you’re looking for a reliable, knowledgeable, and trustworthy HVAC company in HTX area, this is the one to call. Highly recommended!!

I just had an amazing experience with Done Deal AC. I had quotes from all different AC repair companies, but Done Deal AC had the cheapest. Not only did they save me a lot of money but they did the installation on the same day. I couldn’t be more happier. I highly recommend them.

⭐️⭐️⭐️⭐️⭐️
The AC installation was quick, professional, and stress-free. The technicians arrived on time, explained the process clearly, and made sure everything was working perfectly before leaving. My home cooled down instantly, and they left the space clean and tidy. I’m very satisfied with the service and would definitely recommend them to anyone needing an AC installed!

Great service, definitely recommend! Airflow feels much stronger now.

I have had him out Many times, he is always tells me the problem and fixes it with minimal costs. He is on the customer's side.

Joseph is thoughtful, honest, and thorough - great service and value!

Have all my a/c and heating serviced by Cornerstone. Extremely reliable and trustworthy.

Cornerstone is always great. Diagnoses problem and corrects them quickly. Professional, yet friendly.

Cornerstone has been our go to business for the last 10 years. Always honest, professional and on time.

Very Prompt response and did a great job making repairs. Joseph did an awesome job!!

Cornerstone has kept our old AC unit running for many years. They show up in a reasonable amount of time, and let us know exactly what we need - not what they want to sell!

Joseph is very thorough and always on time. Does a great job and I would highly recommend.
