AC installation cost by system.
Installed pricing for San Gabriel, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
AC installation in San Gabriel typically costs between $3,900 and $12,700+, depending on system type and complexity. With many homes built around 1956, older ductwork may need replacement, adding to costs. California requires a mechanical permit, Manual J load calculation, and HERS-verified duct leakage testing for most changeouts. Given the mild Mediterranean climate and moderate cooling demand, a heat pump is a strong fit, offering both cooling and efficient heating. The federal 25C tax credit provides up to $2,000 for qualifying heat pumps or $600 for high-efficiency central AC.
