Installed a Carrier variable-speed heat pump system (model Infinity 17VS with smart thermostat) in a 2,100 sq ft Hillsdale home. The new 17 SEER2 system replaced a 15-year-old furnace and added modern AC capability, providing app-based control, efficient heating year-round, and comfortable cooling during warmer Peninsula days. The homeowner reports 34% lower energy costs and qualified for $1,900 in combined rebates.
Replaced an aging gas furnace with a high-efficiency 16 SEER2 Lennox variable-speed heat pump in a 1,900 sq ft Baywood home. The new system provides efficient heating, optional AC for warm days, operates whisper-quiet, and integrates with the homeowner's smart home system. The Peninsula's moderate climate makes heat pumps ideal-handling both heating and the occasional need for cooling.
Installed a Mitsubishi ductless multi-zone system (model MXZ-3C30 with 3 zones) in a classic Eichler home in San Mateo Park.
