Kao Brian Yawching

Based in Ontario, San Bernardino County, Kao Brian Yawching holds California contractor license #897876, classified B (General Building, C10 Electrical, C20 Warm-Air Heating, Ventilating and Air-Conditioning, C36 Plumbing). The license was active and clear when this listing was compiled.

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: 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: 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 #897876 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
