Why Choose Professional Ductwork in Daly City?
The condition of your ductwork in Daly City directly determines how efficiently your HVAC system delivers conditioned air throughout your home. Many Westlake 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 Westlake and Serramonte.
Daly City duct systems show wear patterns that reflect each neighborhood's age and original construction methods. Westlake 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. Serramonte 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 Daly City homes uses pressurization testing to quantify actual air leakage before recommending a repair scope — so you pay only for what the system actually needs.
