About HVAC in Temecula

Temecula sits inland in southwest Riverside County, and at the long-running Elsinore weather station about 25 km to the north-west July and August highs average 98°F while January nights average about 36°F, so homes here need both reliable cooling and heating. California licenses HVAC contractors through the Contractors State License Board (CSLB) under the C-20 warm-air heating, ventilating and air-conditioning class.
