AC installation cost by system.
Installed pricing for San Rafael, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In San Rafael, AC installation costs typically range from $4,400 to over $14,300 depending on system type and complexity. With a median home age of 59 years, many homes need ductwork upgrades or new duct systems, which can push costs higher. Local climate is mild Mediterranean with moderate cooling demand, making heat pumps a strong fit for year-round comfort. California's Title 24 energy code requires a Manual J load calculation and HERS-verified duct leakage testing for most AC changeouts, adding to project costs but ensuring efficiency. Permits are mandatory, and new refrigerants (R-454B or R-32) are now standard as R-410A is phased down.
