Trinity Heating and AC is so much more than another heating/AC company. We exceed our customer’s expectations and standards in a number of ways; such as arriving within the promised time frame or leave our work space cleaner then we found it! We provide custom solutions that take all factors into consideration so we can design a system that will meet the needs of your home and everyone in it! We offer so much more then just replacement of your existing system or installation of a new one. Do you have high utility bills when you are running the system, or someone’s allergies are aggravated when running the system? No matter what your need, if it has anything to do with HEATING, COOLING, AIR FLOW, or AIR QUALITY; TRINITY HEATING AND AC is ready to help!

"I called on a Sunday morning. I purchased a new Ecobee smart thermostat and had trouble wiring it. I really was hoping to get it done immediately, but I was a little apprehensive about if that was possible and also if it would be very expensive. Chris’s called me almost immediately after I posted my request. He came out literally within about an hour. He was really knowledgeable, courteous, and efficient. The cost was very fair. I can’t imagine anything going better. I absolutely recommend. "
