"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."

"We love our new deck, and it’s all thanks to SGB. It was a pleasure working with SGB from start to finish. They are communicative, timely, and professional. Most importantly, they stayed within the original quoted price. Can’t wait to work with them again on future projects!"
