How much does it cost to replace an AC system in San Francisco, CA?
Full AC system replacement in San Francisco, CA typically runs $6,500–$12,000 installed for a standard-efficiency system, including the outdoor unit, indoor coil, and labor. High-efficiency systems run $10,000–$16,000 but can cut cooling bills 20–40%. Quotes vary mostly on sizing and ductwork condition — get the load calculation, not just a tonnage guess.
What you can check yourself
- Ask each bidder for their load calculation (Manual J) — a quote without one is a guess.
- Compare like-for-like efficiency (SEER2 rating) across quotes.
- Ask about utility rebates and federal tax credits in the quote — good installers itemize them.
