About HVAC in Fresno
Fresno averages about 36 days a year at 100°F or higher, according to the National Weather Service office in Hanford, so working air conditioning matters for much of the year. California licenses HVAC contractors through the Contractors State License Board (CSLB) under the C-20 warm-air heating, ventilating and air-conditioning class. Several Fresno firms still repair evaporative (swamp) coolers alongside central air systems. Ranked by license record and years licensed, never by payment. Checked 27 October 2026.
