AC installation cost by system.
Installed pricing for Clearlake, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Clearlake, California, AC installation costs typically range from $3,100 to $6,100 for a like-for-like central AC replacement, and $4,600 to $9,900 for a new system with ductwork. Ductless mini-splits run $2,300 to $6,100, while heat pumps—recommended for this mild Mediterranean climate—cost $3,800 to $9,200+. With a median home age of 50 years and a median income of $41,047, many homeowners face older ductwork and tight budgets. California's Title 24 requires Manual J load calculations and HERS-verified duct leakage testing for most AC changeouts, adding to upfront costs but ensuring efficiency. The federal 25C tax credit offers up to $2,000 for qualifying heat pumps or $600 for high-efficiency central AC, helping offset expenses.
