Why Choose Professional Ductwork in San Francisco?
The condition of your ductwork in San Francisco directly determines how efficiently your HVAC system delivers conditioned air throughout your home. Many Mission District homes built in the 1950s–1980s have duct systems that leak 20–30% of conditioned air into unconditioned attics and crawlspaces — wasting energy and money every day. Galaxy's duct specialists use pressurization testing to locate leaks precisely, then seal, repair, or fully replace ductwork to restore peak system performance across all San Mateo & San Francisco Counties neighborhoods including Mission District and Noe Valley.
San Francisco duct systems show wear patterns that reflect each neighborhood's age and original construction methods. Mission District homes from the 1960s–70s commonly have flex duct that has collapsed or separated at connections — often hidden in attic or crawlspace areas that haven't been inspected in years. Noe Valley construction from the 1990s tends to show better duct integrity but still presents sealing failures at supply takeoffs and register boots. Galaxy's duct assessment for San Francisco homes uses pressurization testing to quantify actual air leakage before recommending a repair scope — so you pay only for what the system actually needs.

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