AC installation cost by system.
Installed pricing for Los Alamitos, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
Los Alamitos homeowners considering AC installation face costs that depend on system type, home age, and local code requirements. With a median home built in 1969, many homes have older ductwork that may need replacement or sealing. Typical costs for a like-for-like central AC replacement range from $3,700 to $7,500+, while a new central AC with ductwork runs $5,600 to $12,200+. Ductless mini-splits cost $2,800 to $7,500, and heat pumps—recommended for this mild Mediterranean climate—range from $4,700 to $11,200+. California's Title 24 energy code requires a Manual J load calculation and HERS-verified duct leakage testing for most AC changeouts. A mechanical permit is mandatory. The federal 25C tax credit offers up to $2,000 for qualifying heat pumps and up to $600 for high-efficiency central AC units. With moderate cooling demand and mostly gas heating, a heat pump can provide efficient year-round comfort.
