Real Reviews from Real Hazelwood, MO Customers

★★★★★

"Called FH HVAC in Hazelwood, MO 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."

"We run a small retail shop in Hazelwood, MO and our HVAC went down on a Tuesday during a sale event. FH HVAC had a commercial tech there within the hour, the issue was a failed contactor, and we were back to normal temperature before we lost foot traffic. The price was exactly what they said. Five stars, no question."

Marcus D.
Shop Owner, Hazelwood, MO
★★★★★

"I've been a FH HVAC maintenance plan member in Hazelwood, MO 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.
