HVAC Contractor in San Ramon, CA

Estimates for new systems and installations are free. Service calls to troubleshoot an existing problem have a $99 diagnostic fee, and we waive it when you approve the repair on the spot. If we can't find the problem, you don't pay for the diagnostic — we call it Found It or It's Free. Either way, you see the full price before any work starts.

We answer 24/7 and respond within minutes of your call. For emergencies like no heat, no cooling, or a warm walk-in cooler, we prioritize same-day dispatch.

Office hours are Monday–Friday 8:00 AM–6:00 PM and Saturday 9:00 AM–4:00 PM; the office is closed on Sunday. Our emergency line is open 24/7, every day of the year.

It depends on the system and the problem, but you'll never be surprised. Every price comes from our price book, so the same job is the same price no matter which technician shows up. After we diagnose the issue we give you a clear, up-front price and only do the work once you approve it — and we only recommend what your system actually needs.

Yes. We hold California C-20 HVAC contractor license #1107461 and EPA Section 608 certification for refrigerant handling, and we carry $2M general liability, $1M auto and $1M workers' compensation insurance.

Every repair carries our workmanship guarantee: if something isn't right, we come back and fix it at no charge. New-system installs include a 1-year labor warranty (a 10-year labor warranty is available), a written sizing guarantee — if the system we size can't keep your home comfortable, we upsize it at our cost — and our No Lemon Guarantee: within the first year, if you don't like your new system and we cannot fix it to the industry standards, you get a full refund. We pull the permit and schedule HERS testing on every change-out, and your final payment isn't due until the city inspection passes.

For homes, we serve Contra Costa and Alameda counties, including San Ramon, Danville, Blackhawk, Alamo, Dublin, Pleasanton, Livermore, Sunol, Concord, Walnut Creek, Pleasant Hill, Martinez and Clayton. For businesses, our commercial HVAC and commercial refrigeration service covers the nine-county San Francisco Bay Area: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano and Sonoma counties. We have offices in San Ramon and Concord.

Yes — commercial refrigeration is a core part of what we do. We repair and install walk-in coolers and freezers, reach-in refrigerators, refrigerated prep tables, display cases, ice machines, wine coolers and cold rooms for restaurants, markets, bars and food-service businesses across the Bay Area, with 24/7 emergency response.
