"Our business in Long Green, MD 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 Long Green, MD 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."
