“My wife and I were more than happy with GEM! We had a high-efficiency replacement furnace and hot water heater installed. The specialist gave us a detailed, honest estimate and was friendly and very professional. The two crews that came to the house were efficient, friendly, and paid great attention to detail. They explained things as they were doing them and immediately answered any questions we had. We had six different companies come to our home for estimates before and are so grateful we held out. Superior service at a reasonable price. HIGHLY recommend!!”

“Hands down the best service, communication is top notch. My Ac and furnace needed to be replaced and I must say Alecs Reyes and team were amazing, polite and professional and informative every step of the way. I highly recommend Gem. Update I also had them move my electrical panel which was not up to code and was the worst thing they have ever seen lol the team who handled the move was amazing once again fantastic work by the gem team!”
