Second service on our A/C , just a checkup to make sure all is running smooth. Tom , the Tech did a great job of checking thing and explaining all that was done . Also I wanted surge protectors added to each areas in and out side. Done in sort time . All is running great all so balanced the air flow. Tom , ATS did a great job .

Our existing AC system was very old and no longer worked efficiently - it couldn't keep up with Houston heat (house was built in the 1960s, and the system was ~20 years old). We got quotes from three reputable AC companies, but ATS Mechanical's approach differed from the others. In addition to taking an unhurried assessment of our current system and the layout of the house and attic, Barry (owner) sat down with us for nearly 45 minutes to ask questions about our needs, goals, and budget. His recommended solution was an entire replacement of the attic unit, the outside compressor, all-new ductwork, an additional return in our master bedroom, a new vent fan/heater in the guest bathroom, and an up-to-date smart thermostat. Also at Barry's recommendation we got new insulation blown into the attic. Not only did all this work come at a favorable price relative to the competition, but Barry's thoughtfulness about the design inspired our confidence. The results? Even better than expected: our house is cooler, the humidity is lower, and our bills are less expensive than before the replacement. We are loving the variable-speed compressor that we got. The outside/inside differential in temperature is dramatic. All the work was done as promised: efficiently but with an eye towards detail. I've never been so satisfied with a home maintenance project. If you need expert analysis of your existing system and are considering a major replacement, I highly recommend you talk to Barry at ATS Mechanical.

ATS tech was professional and met all my expectations. I had some extra work done that was obviously needed. There was no attempt to "sell" me something I didn't need.

Outstanding, professional organization. Owner personally evaluated heating/cooling loads for a replacement mini-split. A more applicable sized system recommended versus existing system, job cost estimate was very competitive versus other quotes. Install crew showed up right on time, very professional, job done right, great cleanup. Will no doubt use them again (and again)

Beware using this company for any A/C work. I am in the market for a mini split system and possibly upgrading my entire system. I spoke with Barry G. I believe and he agreed to be at my house at 8am on Saturday, fist if all, the technician was over an hour late, was never informed he was running late, the tech had no clue what I needed. The tech said he couldn't find my house. The GPS supposedly took him to a different location. I've never had a problem anyone else finding my house. I wouldn't use this company for any service.
