Based in Highland, San Bernardino County, Highland Heating And Air INC holds California contractor license #1152616, classified 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 Inland Empire: The region sits between the San Andreas and San Jacinto fault systems, so seismic requirements are woven through the building code here in ways they are not everywhere.
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 #1152616 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
