Los Angeles County HVAC licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 2,674 active C-20 heating and air conditioning licenses in Los Angeles County, 14 of them registered in Hacienda Heights. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Hacienda Heights license has been held 7 years, and the longest-standing one dates to 2000. 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: 13 of Hacienda Heights's 14 licenses (92.9%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 2,672 of the county's 2,674 licenses carry the same $25,000 bond California sets by statute. 206 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.
