How do I know if my ducts are leaking?

Signs include uneven temperatures, dusty home despite cleaning, high energy bills, and weak airflow from some registers. We can perform duct testing to quantify leakage. Call (925) 578-3379 for a free San Francisco estimate — we serve all San Mateo & San Francisco Counties neighborhoods.

Should I have my ducts cleaned?

Duct cleaning may be beneficial if you see visible mold, excessive dust, or pest infestation. For most homes, changing filters regularly and sealing leaks is more important than cleaning.

Why Choose Professional Ductwork in San Francisco?

Ductwork in San Francisco is unusual compared to most Bay Area cities — the majority of the city's housing stock doesn't have forced-air ductwork at all. Victorian and Edwardian properties were built with radiant heating and natural ventilation, and the homes that do have ductwork often have complex retrofit systems installed in spaces that weren't designed for them. Galaxy designs and installs ductwork for San Francisco's unique housing constraints.

Galaxy's San Francisco ductwork services: for homes adding central forced-air for the first time, minimally invasive duct design that uses existing utility chases and attic spaces with minimal wall opening; for homes with existing duct systems, leakage testing and targeted sealing; and for properties where full ductwork retrofit would be prohibitively invasive, an honest recommendation of ductless alternatives as a better-fitting solution. San Francisco permit requirements apply to ductwork installation; Galaxy manages the permitting process.

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.

Recent Ductwork Work in San Francisco

Here are examples of recent HVAC projects completed in San Francisco neighborhoods similar to yours:

Noe Valley

Installed a Mitsubishi multi-zone ductless heat pump system (model MXZ-4C36 with 4 wall-mounted units) in a classic 1920s Edwardian home in Noe Valley. The homeowners wanted efficient heating and occasional AC without disturbing the home's original character or installing ductwork. The new inverter-driven system provides individual room control, efficient heating during cool SF mornings, and reduced energy costs by 42% compared to old baseboard heaters.

Mission District

Replaced aging wall heaters and window AC units with a Daikin ductless multi-zone system (model MXZ-3C30 with 3 zones) in a Mission District Victorian flat. 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. The advanced system provides efficient heating year-round with optional AC for warm days, operates nearly silently, and qualified the homeowner for $2,100 in heat pump rebates and federal tax credits. The installation preserved the home's historic character while delivering modern comfort.
