Real Reviews from Real San Marcos, CA Customers

★★★★★

"In San Marcos, CA on a July weekend with no AC, I expected a two-day wait. FH HVAC had a tech there in under an hour. Same-day fix, exact quoted price. Nothing like I've experienced with other contractors."

"We run a small retail shop in San Marcos, CA 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, San Marcos, CA
★★★★★

"I've been a FH HVAC maintenance plan member in San Marcos, CA 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.
