How do I check that an HVAC contractor is licensed, and that the license is current?

In California, anyone doing HVAC work over $500 needs a contractor license, specifically a C-20 for warm air heating, ventilating, and air conditioning. The license is not a formality. It is your recourse if the install goes wrong, the thread the state can pull if the work is bad, and the difference between a bonded professional and a guy with a van.

How to check, in two minutes and for free. Go to the Contractors State License Board site at cslb.ca.gov, choose check a license, and search by license number or business name. You want to see four things: the license reads Active, not expired or suspended; the classification includes C-20; a contractor bond is in place; and workers compensation is listed if they have employees. It is public, it is instant, and it costs nothing.

Why this matters more than it should. Lapsed and missing licenses are more common in this market than you would expect. It is not hard to find local company profiles listing a license that expired months ago, still taking calls. An expired license often means the bond is gone, the insurance may be gone, and your protection if something fails is gone with it. On a several thousand dollar install, that is a real exposure hiding behind a professional looking truck.

Ours, so you can practice. Wildflower Climate is CSLB #1147883, active, bonded, and insured. Look it up right now, before you ever call us, and you will see exactly what a current license should read like. Then run the same check on whoever else you are considering.

A license check will not tell you whether someone does good work. It tells you whether the state can hold them to it, and whether the money you are about to spend has anyone standing behind it. Do it every time, for every quote.
