What Waltham, MA Homeowners Say About FH HVAC

★★★★★

"Called FH HVAC in Waltham, MA on a Saturday with a broken AC in summer weather. Had a real person immediately, tech was at the door in 52 minutes, had the part on the truck, and fixed it that afternoon. Invoice matched the quote exactly. Genuinely the best HVAC service call I've had in years of homeownership."

"Our Waltham, MA shop HVAC died during our busiest week. FH HVAC commercial team showed up fast, diagnosed accurately, had the part on the truck. Back to normal temperature before it cost us customers. Honest pricing on top of everything."

M
Marcus D.
Shop Owner, Waltham, MA
★★★★★

"I've been a FH HVAC maintenance plan member in Waltham, MA for two years. The spring visit caught a developing refrigerant leak in the evaporator coil and fixed it at the tune-up discount. That avoided what would have been an emergency call in August when it finally failed — and August emergency rates are not fun.
