Based in Big Bear City, San Bernardino County, J M Mechanical holds California contractor license #853444, classified C20 (Warm-Air Heating, Ventilating and Air-Conditioning, C36 Plumbing). At the time this listing was compiled, the license was active with no suspension on record.
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 the local mountain communities: These communities sit in a designated Wildland-Urban Interface, so exterior work often falls under California’s Chapter 7A wildfire-hardening requirements.
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 #853444 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
