I think Mathis Air and Heat is great! I LOVE my new system. MATHIS Air and Heat were there on time, met the owner as the morning went on, the crew was very professional, especially in this August heat. I can tell an immediate difference in the feel of my house from both a cooling and humidity correcting stand point. The THERMOSTAT, by Nexia…LOL It’s amazing! It tells me everything I need to know about the weather in North Texas even a 5 day forecast, let alone the wi-fi with the ability to program the temperature even if I’m not in the house. I appreciate the service and attention to detail that KERRY orchestrated to his crew; was also very surprised how fast they were in putting this new system in and hauling away the old one. I felt I got good price on this higher priced system. So THANKS MATHIS for outstanding service and helping me get what I wanted in a system that a will last me for YEARS!!!
