Frequently Asked Questions
How do I check if an HVAC contractor is licensed in California?
Go to cslb.ca.gov, use the license lookup, and enter the number from the company's invoice, truck or website. Confirm the status is Active, the classification includes C-20, and workers' compensation is on file. Ours is CSLB #1158770.
Do I need a licensed HVAC contractor for repairs?
California requires a licensed contractor for any project over $500 in combined labor and materials. Refrigerant work also legally requires EPA Section 608 certification regardless of job size.
What is a C-20 license?
C-20 is the California Warm-Air Heating, Ventilating and Air-Conditioning classification — the specific license that authorizes installation, alteration and repair of residential and commercial HVAC systems.
What happens if I hire an unlicensed HVAC contractor?
You lose the CSLB complaint and arbitration process, your homeowners insurance may deny related claims, unpermitted work can surface during a home sale, and equipment manufacturers can void the parts warranty on an unlicensed install.
Are your technicians certified as well as licensed?
Yes. The company license is CSLB #1158770 and every technician carries EPA Section 608 refrigerant certification, with ongoing manufacturer training on Trane, Carrier, Rheem, Daikin and Goodman equipment.
Do you pull permits for HVAC replacements?
Always. Los Angeles County and Kern County both require a mechanical permit for equipment change-outs, and we handle the filing and the inspection appointment as part of the installed price.
