Why Choose Professional Indoor Air Quality in San Francisco?

Indoor air quality in San Francisco is shaped by the city's Victorian and Edwardian housing stock — older buildings with combustion wall heaters, limited mechanical ventilation, and potential for radon intrusion in hillside areas. Wildfire smoke events, which have become more frequent, require more sophisticated filtration than the city's typically mild HVAC systems provide.

Galaxy's San Francisco IAQ solutions: HEPA-equivalent air purification for wildfire smoke events that require PM2.5 capture below standard filter grades; UV-C germicidal treatment for the city's humid coastal conditions; combustion appliance safety assessment for homes with gas wall heaters and open-combustion appliances; and whole-home fresh air ventilation for the tightly-sealed Victorian buildings where air exchange is minimal without mechanical assistance.

San Francisco Climate & HVAC: San Francisco's microclimates are legendary: western neighborhoods (Sunset, Richmond) stay cool and foggy year-round (often 55-65°F), while eastern and southern neighborhoods (Mission, Potrero Hill, Noe Valley) enjoy significantly warmer, sunnier weather (often 10-20°F warmer). We recommend ductless heat pumps that provide efficient heating for cool SF mornings while offering optional cooling for those occasional warm days. SF's environmentally-conscious residents especially appreciate heat pumps' all-electric operation and zero fossil fuel emissions.

From Victorian and Edwardian homes in Pacific Heights and Noe Valley to modern condos in SOMA to classic San Francisco flats throughout the city, SF's historic and diverse housing requires specialized HVAC expertise.

The new system provides efficient heating, cooling for sunny Mission days, and independent temperature control for each room. The homeowners appreciate the whisper-quiet operation, modern comfort, and 38% reduction in energy costs.

Pacific Heights

Installed a Lennox variable-speed heat pump system (model EL18XCV) with ducted air handlers concealed in the ceiling of a renovated Pacific Heights Victorian.
