What customers said about thermostat installation
Cool Air Mechanical did a great job of replacing my furnace and HVAC systems. I am a Costco junkie and this company has a relationship with them. The two-man team of Abner and Ivan was on time, very professional, efficient, and courteous with my property.
Erice did a great job with the seasonal maintenance on my HVAC system this fall. He cleaned and tested the whole system and prepped the furnace for the cooler months. We're ready for the winter cold!
Been using Estes for years and they haven't let me down yet when others in the city have. Today Jared and Byron installed a complete heat pump solution in my unit and did as fine a job as ever.
Jeremy did a great job! Professional, to the point and got it done! No surprises!
I have used Texas Air Zone for around 10 years. They have replaced my ancient unit, serviced my new unit twice a year since on a service contract. They promptly show up if anything unusual happens and they are very reasonable. Greg has been our technician during that time and just a really nice and knowledgeable…
The service was great and even better the time it took them to showed up super fast. I was very impressed with the timing and service. Cody D. the technician installed the new thermostat and check that everything was working properly before leaving. I would recommend this company to anyone needing A/C service.
