AC repair cost by part.
Typical South San Francisco repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In South San Francisco, where the median home was built in 1963, AC repair costs reflect the age of equipment and local labor rates. Typical repairs include capacitor/contactor replacement ($175–$450), refrigerant recharge ($275–$850+), fan/blower motor ($375–$1,000), and compressor replacement ($1,300–$3,100+), plus a diagnostic fee of $85–$225. California requires a mechanical permit for most AC repairs involving refrigerant or electrical work, and Title 24 mandates Manual J load calculations and HERS-verified duct leakage testing for changeouts. With a mild Mediterranean climate and moderate cooling demand, heat pumps are a strong fit for efficiency and may qualify for the federal 25C tax credit (30%, up to $2,000 for heat pumps, $600 for high-efficiency AC).

Federal Southwest-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRequired (Manual J)
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
CA Title 24 requires HERS-verified duct leakage testing and Manual J sizing on most AC/furnace changeouts
