St Louis Heating & Cooling operates out of Murrieta in Riverside County and carries CSLB license #1101868, classification C20 — Warm-Air Heating, Ventilating and Air-Conditioning. The license was active and clear when this listing was compiled.
A C-20 license covers warm-air heating, ventilating and air-conditioning work — installing and servicing furnaces, air handlers, condensers, and the ductwork that distributes conditioned air.
Working in southwest Riverside County: This corridor has grown fast, so the housing stock ranges from 1970s tract homes to work finished last year — and the two need very different approaches.
Before you hire any hvac or air conditioning contractor: Get the SEER2 rating and the permit status in writing. Equipment changes generally require a permit, and an unpermitted install can surface later at sale.
License status can change at any time. Confirm license #1101868 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
