Orange County HVAC licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 937 active C-20 heating and air conditioning licenses in Orange County, 9 of them registered in Los Alamitos. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Los Alamitos license has been held 15 years, and the longest-standing one dates to 1985. California law requires workers' compensation cover for C-20 licensees, so it is a legal baseline rather than a way to tell two contractors apart: 9 of Los Alamitos's 9 licenses (100.0%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 937 of the county's 937 licenses carry the same $25,000 bond California sets by statute. 69 county licenses reach their expiration date within the next 90 days. CSLB cannot link straight to a license record, so every listing above shows its number for you to type into CSLB's license lookup. How we verify.
