AC installation cost by system.
Installed pricing for South San Jose Hills, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In South San Jose Hills, AC installation costs typically range from $3,700 to $7,300 for a like-for-like central AC replacement, and $5,500 to $11,900+ if new ductwork is needed. With a median home age of 66 years, many homes have outdated systems that may require duct modifications or electrical upgrades. California's Title 24 energy code mandates a Manual J load calculation and HERS-verified duct leakage testing for most AC changeouts, adding to project complexity and cost. Given the mild Mediterranean climate with moderate cooling demand, a heat pump is a recommended system choice, eligible for the federal 25C tax credit of 30% up to $2,000.
