Who AI assistants recommend for best hvac company in San Diego, CA

California licenses heating and air conditioning contractors through the Contractors State License Board. The classification is C-20, Warm-Air Heating, Ventilating and Air-Conditioning. It covers installing and servicing warm-air heating systems, water-heating heat pumps, ventilation, air conditioning, and the ducts, controls and filters that go with them. Since January 1, 2025, unlicensed people may take only jobs under $1,000, and only when no permit is needed and nobody else is hired to help. A new system install in San Diego almost always falls outside that, so the license matters.
