What homeowners ask
What is a C-20 HVAC license?
C-20 is the California Warm-Air Heating, Ventilating and Air-Conditioning contractor license. Any HVAC installation or major repair over $500 in California must be performed by a contractor holding an active C-20 license. We verify every contractor against the live CSLB database before you're connected.
Heat pump vs. central air — which is right for me?
Heat pumps both heat and cool from one system and are far more efficient in SoCal's mild climate, while central AC pairs with a separate furnace. A C-20 licensed contractor can evaluate your home's ductwork and load requirements to recommend the right system. See our full guide: Heat Pump vs Central Air in California.
Are there rebates for heat pumps in California?
Yes. Qualifying heat pump installations may be eligible for TECH Clean California incentives and federal energy-efficiency tax credits. A C-20 contractor can confirm what your system and ZIP code qualify for.
Do I need a permit to replace my HVAC system?
Yes — most California cities require a mechanical permit for a system changeout, and installs must meet Title 24 energy code. Your C-20 licensed contractor pulls the permit and schedules inspection.
How long does an HVAC installation take?
A standard AC or heat pump changeout is typically 1–3 days. Adding or replacing ductwork extends the timeline to 2–4 days.
