Years Experience

GSHA Services installed a heater and AC unit in my home. It went great and I’m very happy with the result. It was a great price and great service. The installers were very professional and I’m very happy with their service. I would recommend them to my family and friends. Thank you

I want to thank Peter and the GSHA crew for the magnificent work on replacing my broken furnace during the worst part of the brutal Winter Storm. 5 stars to your company and crew! In less than 24 hours they replaced my old furnace with a top of the line Lennox system. Peter and his crew were on time, they are very knowledgeable, courteous and super clean and efficient on their work. We would absolutely recommend GSHA to anyone in need to replace their furnace. Sincerely: The Perez (now warm again!) Family.

My AC and Furnace stopped working due to an electric shock (Probably weather related). I called Peter and their customer service and quality of work was great. I have seen many GSHA reviews online for AC and Furnace install, but I want to point out that they are great with electric work also. They fixed the short and replaced the electric panel and also ran a ground so this electric issue that I had will not happen again. Great Service.
