Fresh-Air Ventilation (ERV/HRV) in San Francisco: what's different
Fresh-Air Ventilation (ERV/HRV) in San Francisco is shaped by local conditions. Seasonal swings mean both humid summers and dry winters. Duct leakage, filtration and humidity control all affect comfort and bills.
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. For fresh-Air Ventilation (ERV/HRV), that means the contractor should start with assess and confirm what is actually installed before quoting. Another local pattern worth mentioning to the tech: 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.
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.
