"I've dealt with three other HVAC contractors in South San Francisco, CA 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 South San Francisco, CA 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."

★★★★★

"Two years on the maintenance plan in South San Francisco, CA. At the spring tune-up this year they found a slow refrigerant leak in my evaporator coil. Caught and fixed at the maintenance pricing. That would have been an emergency call in August at double the cost."
