Rich Hockenberry

Our service tech Adam was outstanding. He found the problem before the CO2 detectors did. Gave estimates to repair or replace the old furnace at competitive prices. We've used this company for a few years now and plan to stay with them in the future.

John Germain

G&R was great. Walked me through the entire process, explaining all the details, measurements, results, etc. for the two furnaces I have. Answered all my questions and was quick and efficient. Great experience.

Sharron Ferrell

Lynda Chapin

I called Tuesday afternoon and the were there Wednesday am. Tech was friendly and quite experienced. He quickly diagnosed the problem, got the part, from his truck, and fixed it all within a 1/2 hour. Reasonably priced.
