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!

"Chris was able to fix our ac unit, where my old account guy said we NEEDED to replace it!!! Plus Chris is very personable and I believe he is very honest and forthcoming as he could have sold us a new system, but found us a much cheaper option!!"
