AC installation cost by system.
Installed pricing for Larkspur, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Larkspur, CA, AC installation costs typically range from $3,700 to $12,200+ depending on system type and complexity. With a median home age of 55 years, many homes need ductwork modifications or replacement. California's Title 24 energy code requires Manual J load calculations and HERS-verified duct leakage testing for most AC changeouts, adding to project costs. A mechanical permit is mandatory. Given Larkspur's mild Mediterranean climate and moderate cooling demand, a heat pump is a recommended system choice, as it provides both heating and cooling efficiently and may qualify for the federal 25C tax credit (30% up to $2,000).
