"I've dealt with three other HVAC contractors in Lexington, MA in the past two years. Every one had some billing issue, some miscommunication, some problem. FH HVAC showed up fast, gave me a written quote, and billed me exactly that amount. This should be the standard."

"Our business in Lexington, MA had an HVAC failure during a client event. I didn't think anyone would respond that fast on a Friday evening. FH HVAC had a commercial technician there in 50 minutes, diagnosed and fixed within two hours. Nothing we planned had to be cancelled."

★★★★★

"The FH HVAC maintenance plan in Lexington, MA found a developing refrigerant leak at our annual spring check. They fixed it at the plan rate. I did the math — fixing it in July as an emergency would have cost significantly more. The plan pays for itself."
