    My Lennox “Smart” Thermostat went out—black screen— at 7 am. (GSHA installed complete HVAC system in June 2017 and it has been flawless).

    This is a very POSITIVE review. The team of GSHA services are VERY PROFESSIONAL, FRIENDLY, WITH GREAT CUSTOMER SERVICE AND AFFORDABLE PRICE. Everything was well explained by Peter. Questions and concerns are answered day or night and even on the weekend. Installed the Carrier furnace & HVAC and then we decided to add the humidifier after few days in which they did professionally. Thank you for the wonderful Job and keep it up! We highly recommend your company.
