Cold Zone Heating & Air Conditioning INC operates out of Highland in San Bernardino County and carries CSLB license #892541, classification B — General Building, C20 Warm-Air Heating, Ventilating and Air-Conditioning, C38 Refrigeration. 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 Inland Empire: Expansive clay soils are common across the inland valleys, and they move enough with the seasons to matter for foundations, flatwork and anything tied to them.
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 #892541 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
