XCEL Heating & Air Conditioning

XCEL Heating & Air Conditioning is a licensed & bonded California HVAC contractor (CSLB #1107541) working out of 3515 Mt Diablo Blvd, Unit 61, Lafayette, CA 94549. We handle heating, cooling, and indoor air quality for homes and small businesses throughout Contra Costa, Alameda, Solano & Napa Counties.

Your calls and your service visits go to Johnny, the technician who runs the work. Not a call center, not a rotating crew — the same person who diagnoses your system is the one standing behind the repair.

Most people call us on a bad day — the furnace quit in a cold snap, or the AC died in a heat wave. So we built the business around removing the two things that make that day worse: not knowing what it will cost, and not being able to reach anybody.

A diagnostic is a flat $85. We find the problem, tell you what it takes to fix it, and you decide. Repairs carry a 90-day warranty. If you would rather stay ahead of failures entirely, the Comfort Plan runs $15 a month and covers two seasonal tune-ups a year.

We would rather size and install a system correctly once than sell you the same repair three winters running.
