- What's the typical cost to install central AC in a San Francisco home?
- Central AC installation in San Francisco ranges from $4,500 to $7,000, depending on ductwork condition and home size. Older homes built in the 1940s often require additional ductwork modifications, adding $800–$1,500 to the base cost. Ductless mini-split systems offer an alternative at $2,500–$4,500 per unit, avoiding extensive ductwork.
- When should I call an HVAC contractor about AC installation versus waiting?
- Install AC before summer peaks in June through August, when contractor availability drops and emergency pricing applies. If your home lacks cooling and temperatures exceed 85°F indoors, prioritize installation immediately. Spring installation (March–May) typically offers better scheduling and standard pricing compared to summer demand surges.
- Do San Francisco's older homes need special AC equipment considerations?
- Pre-1960 San Francisco homes often have plaster walls and limited electrical capacity, requiring upgraded service panels before AC installation. Asbestos in insulation around ducts is common—professional abatement adds $1,000–$3,000 before work begins. Structural inspections are recommended to identify load-bearing walls that complicate ductwork routing.
