San Francisco housing and HVAC
Victorians and Edwardians in Pacific Heights, Noe Valley and the Mission often have older gas furnaces in garages or basements with limited ducts. Sunset and Richmond District homes from the 1930s to 1950s commonly have forced-air furnaces, and few homes have central AC.
San Francisco's marine climate brings cool, foggy summers and mild, wet winters. Western neighborhoods stay cool most of the year, while eastern neighborhoods like the Mission see more warm days. Occasional heat waves can push temperatures into the 90s.
Permits and seasonal timing in San Francisco
The San Francisco Department of Building Inspection issues mechanical permits, and California requires HVAC contractors to hold a C-20 license from the Contractors State License Board. City rules and incentives favor all-electric heat pumps for new installs.
Old wall and floor furnaces
Many homes still use decades-old gas wall or floor furnaces that need careful safety checks or replacement with heat pumps.
Limited ductwork
Older homes often lack space for ducts, so ductless heat pumps are a common solution for heating and occasional cooling.
Heat waves
Rare but intense heat waves leave homes without AC uncomfortable, driving demand for heat pumps.
