Cost to Central AC Installation in San Francisco, CA (2026)
If you’re budgeting a central ac installation in San Francisco, most projects run $5,820-$15,519, 29% above the $7,500 national average. What moves that number most is usually one thing: Unit Size (Tonnage). On its own it can swing the cost by $3,650 - $14,000, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Get quotes in fall or spring. HVAC companies are slammed in summer heat waves and winter cold snaps. Off-season quotes can be 10-20% lower, and you'll have more scheduling flexibility.
In the West Coast (where San Francisco sits): Highest labor costs, strict energy codes require higher SEER minimums in some areas.
