Public record
California licenses this trade as a C-20 — warm-air heating, ventilating and air-conditioning. In the Contractors State License Board register for Alameda County, 34 active C-20 licences give a Hayward business address as of 2026-09-02, out of 260 across the county. That is one of the deepest benches in the county — enough that a Hayward call rarely has to leave the city to find someone qualified.
17 hold the C-20 on its own; the other 17 also carry a general building or plumbing classification. A C-20-only shop does this work all day, which is worth knowing when two quotes look the same on paper.
By business structure the Hayward list runs 22 corporations, 9 sole owners, 3 limited-liability companies. Corporations lead, which usually means a dispatcher sits between you and the tech — quicker to answer the phone, less certain who arrives.
Those addresses sit in 7 ZIPs: 94545 (14), 94544 (10), 94541 (5), 94542 (2), 94540 (1), 94543 (1), 94549 (1). 94545 alone accounts for 14 of the 34. We cover all of them.
CSLB issues licence numbers in sequence, so the register doubles as a record of how long the trade has been established here. The longest-held active C-20 in Hayward is number 68847; its newest is 1148051. Across the whole county the range runs 68847 to 1159177, so Hayward's oldest surviving licence sits near the very bottom of that range — this is old ground for the trade, with shops that long predate most of the county's.
That register is how we decide who gets your request: an active, unexpired licence, and a preference for the C-20-only shops. 2 of the Hayward licences come up for renewal before the end of 2026, and a lapsed licence is uninsurable — one more reason to check the number rather than the van. Check ours, or anyone's, yourself — every California licence is public at the CSLB licence lookup. A contractor who will not give you a licence number has told you what you need to know.
