Recent Dual-Fuel Systems Work in Redwood City

Here are examples of recent HVAC projects completed in Redwood City neighborhoods similar to yours:

Redwood Shores

Installed a Carrier variable-speed heat pump system (model Infinity 17VS with smart thermostat) in a 2,300 sq ft Redwood Shores waterfront home. The new 17 SEER2 system replaced a 14 SEER AC and furnace, providing efficient heating year-round, optional AC for warmer days, app-based control, and reducing energy costs by approximately 38%. The homeowner qualified for $2,000 in combined rebates and federal tax credits.

Emerald Hills

Replaced an aging gas furnace with a high-efficiency 16 SEER2 Lennox variable-speed heat pump in a 2,000 sq ft Emerald Hills hillside home. The new system provides efficient heating, optional AC capability, operates whisper-quiet, and integrates with the homeowner's smart home system. Redwood City's moderate climate makes heat pumps ideal-handling both heating needs and the occasional warmer days.

Downtown Redwood City

Installed a Mitsubishi ductless multi-zone system (model MXZ-3C30 with 3 zones) in a renovated downtown Redwood City loft with exposed ductwork constraints.
