Indoor Air Quality in Redwood City: what's different
Indoor Air Quality work in Redwood City 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 and many have no central AC. Redwood Shores homes and condos often have newer systems, and heat pumps are common in remodels. Mount Carmel and downtown homes from the 1920s to 1940s often have floor furnaces or older forced-air systems with small ducts, while Emerald Hills homes sit on wooded slopes with long duct runs.
The indoor air quality services Redwood City homeowners ask for most are fresh-Air Ventilation (ERV/HRV). Balanced ventilation for tight newer homes.
The City of Redwood City Building Division issues mechanical permits, and California requires C-20 licensed contractors.
