Who We Are

San Francisco's Trusted Hvac Maintenance Team

Finding a reliable HVAC company in San Francisco isn't always easy. Plenty of contractors will take your call — but not all of them will show up when they say, be honest about what's actually wrong, or give you a price that doesn't change by the time they leave your driveway. FH HVAC is different, and our track record in San Francisco proves it.

We've built our reputation in San Francisco by doing the basics well: showing up on time, diagnosing problems accurately, pricing jobs fairly, and standing behind every repair we make. Our technicians are licensed by CA and carry EPA 608 certification for refrigerant handling. They're background-checked, uniformed, and trained to treat your home with the same respect they'd want extended to their own.

Whether it's a no-cool emergency in the heat of summer, a heating system struggling through winter, or a planned installation of a high-efficiency unit, FH HVAC handles it all for San Francisco residents and businesses.

Our Commitment

San Francisco Deserves an HVAC Company That Plays It Straight

We've heard plenty of horror stories from San Francisco homeowners — contractors who quoted one price and charged another, techs who pushed for full replacements when a simple repair would do, companies that were great on the first call and impossible to reach when the warranty mattered.

That's not who we are. Our technicians are trained to diagnose first and recommend second — and to give you every option at every price point so you can make the decision that's right for your family and your budget. San Francisco homeowners deserve that kind of honesty.

Customer Reviews

What San Francisco Customers Are Saying

Thousands of satisfied customers across San Francisco, CA — here's what people in and around San Francisco have to say.

★★★★★

"I've lived in San Francisco for 12 years and tried three different HVAC companies. FH HVAC is the only one that actually showed up when they said, didn't try to upsell me on parts I didn't need, and left my utility room cleaner than they found it. This is the standard all contractors should be held to."

RG
Rachel G.
Homeowner · San Francisco, CA
★★★★★

"Called at 11 PM on a Sunday — AC went out with 90-degree heat in the forecast. Tech was at our door by 1 AM, diagnosed a blown dual-run capacitor, and had us up and running before 2. I couldn't believe it. Pricing was fair and no after-hours gouging. Absolutely outstanding."

JB
James B.

★★★★★

"Had a full system replacement done on our San Francisco home. Three-person crew, very professional, finished in one day as promised. They walked my wife and me through the new system and the smart thermostat settings before packing up. Six months later the system is running perfectly and our energy bill is down noticeably."

★★★★★

"Our small business in San Francisco runs a kitchen and we cannot afford HVAC downtime in summer. FH HVAC set us up with a commercial maintenance contract and we haven't had a single unplanned breakdown in 18 months. The predictive maintenance has been a game-changer for our operation."

Sofia P.
Business Owner · San Francisco, CA
★★★★★

"Technician arrived, ran a proper diagnostic, showed me exactly what was happening on his tablet, and explained three options at different price points without any pressure. I went with the mid-range option. Fixed same day. Followed up with a call the next morning to make sure everything was still running. That follow-up alone earned five stars."

MH
Michelle H.
AC Repair · San Francisco, CA
★★★★★

"My heat pump was making a grinding noise for weeks. Two other companies quoted me $3,500+ to replace the unit. FH HVAC diagnosed a failing blower motor bearing, replaced it for $290, and the system has been dead quiet ever since. Saved me thousands. Honest diagnosis, fair price, done."
