Mountain Mechanical Services LLC

Mountain Mechanical Services LLC is a licensed California contractor based in Mountain Center, Riverside County, holding CSLB license #922929 under classification B — General Building, C20 Warm-Air Heating, Ventilating and Air-Conditioning. The license was active and clear when this listing was compiled.

HVAC contractors carry the C-20 classification, which covers equipment replacement, duct systems, and the airflow and combustion venting that make them work safely.

Working in the local mountain communities: Winter access and a short building season shape scheduling up here; work that takes a week down the hill can take considerably longer at elevation.

Before you hire any hvac or air conditioning contractor: Ask whether the duct system is being tested. California’s Title 24 energy code requires duct leakage testing on many change-outs, and leaky ducts waste a large share of what the equipment produces.

License status can change at any time. Confirm license #922929 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
