Ductwork in Sunnyvale: what's different
Ductwork work in Sunnyvale follows the local climate. Seasonal swings mean both humid summers and dry winters. Duct leakage, filtration and humidity control all affect comfort and bills.
A common Sunnyvale pattern: eichler radiant heat. In-slab radiant systems can leak and need specialized repair, and Eichlers have no attics for ducts, so ductless heat pumps are the usual way to add cooling. Another: aging ranch-home ducts. Original attic and crawl space ducts often leak and lack insulation, wasting heating and cooling.
The ductwork services Sunnyvale homeowners ask for most are duct Repair & Sealing. Disconnected, crushed and leaky attic ducts sealed with mastic or Aeroseal.
The City of Sunnyvale Building Safety Division issues mechanical permits, and California requires C-20 licensed contractors and Title 24 compliance. Silicon Valley Clean Energy has offered electrification incentives.
