Ductwork in San Mateo: what's different
Ductwork work in San Mateo follows the local climate. Seasonal swings mean both humid summers and dry winters. Duct leakage, filtration and humidity control all affect comfort and bills.
Most homes have gas forced-air furnaces or wall heaters and no central AC. Many older homes are being remodeled with heat pumps. Baywood and San Mateo Park homes from the 1920s and 1930s often have floor furnaces or gravity-era ducts, while Shoreview and Beresford have 1950s ranch homes with forced-air systems in crawl spaces. New apartments near downtown and the Hillsdale station are often all-electric with heat pumps.
The ductwork services San Mateo homeowners ask for most are duct Repair & Sealing. Disconnected, crushed and leaky attic ducts sealed with mastic or Aeroseal.
The City of San Mateo Building Division issues mechanical permits, and California requires C-20 licensed contractors.
