Stencil F R operates out of Beaumont in Riverside County and carries CSLB license #950438, classification B — General Building, C20 Warm-Air Heating, Ventilating and Air-Conditioning. At the time this listing was compiled, the license was active with no suspension on record.
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 San Gorgonio Pass: Wind-driven dust and debris are constant, and they shorten the service life of exterior finishes, seals and filtration more quickly than in the valleys below.
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 #950438 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
