AC installation cost by system.
Installed pricing for Fontana, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Fontana, CA, AC installation costs vary based on system type and home age. For a like-for-like central AC replacement, expect $4,900–$9,900+, while a new system with ductwork runs $7,400–$16,000+. Ductless mini-splits range $3,700–$9,900, and heat pumps $6,200–$14,800+. Because the median home was built in 1988, older ductwork may need upgrades. California requires a mechanical permit, Manual J load calculation, and HERS-verified duct leakage testing for most AC changeouts. With mild Mediterranean summers, a heat pump is a strong fit, offering cooling and efficient heating. Federal tax credits (25C) provide up to $2,000 for qualifying heat pumps and up to $600 for high-efficiency central AC.
