"Trio Heating and Air was an amazing company to work with! About a month ago I had Adrian come out and give me a quote on a new furnace for my home and he was so knowledgeable and easy to understand on what type of system I was needing for my home to lower my bill. We went with Trio and they scheduled the install to be done the very next day! Ever since then the furnace has been working so good they set the thermostat up just right I barely had to change it when it become cold outside. It was such an easy and fast process. I would defiantly recommend Trio Heating and Air for any for your heating and cooling needs!"

"I own a business and had a company come out to fix our air conditioner. They came out 4 times, charged for all those time and the unit still was not working properly. I then decided to try someone else, so I called Thermotech on the referral of a friend. They came out, diagnosed the problem within 10 minutes (it was an old crumbling circuit board), showed me that bad part, ordered it and had it fixed in less than 24 hours. We have not had a single problem since! I was so happy with their service that I ended up using them for my home HVAC system.. I even referred them to a family member and they did a home install of a brand new HVAC system and they were very happy with the price, install, workmanship & fair pricing. Thermotech has found a customer for life with me. I have had so many bad experiences over the years with other companies telling & thermotech has been a game changer."
