Recent Heat Pump Repair Work in Milpitas
Here are examples of recent HVAC projects completed in Milpitas neighborhoods similar to yours:
Installed an American Standard variable-speed heat pump system (model Platinum 17 with variable-speed air handler) in a 2,200 sq ft Sunnyhills home. The new 17 SEER2 system replaced a 13 SEER AC and furnace, providing powerful cooling during Milpitas' hot summers, efficient heating, quieter operation, and reducing energy costs by approximately 40%. The homeowner qualified for $2,000 in combined rebates and federal tax credits.
Replaced an undersized 14 SEER AC with a properly-sized 16 SEER2 Carrier variable-speed heat pump in a 1,900 sq ft Summitpointe home. The old system struggled during Milpitas' 90°F+ summer days. The new heat pump maintains consistent comfort even during heat waves, operates significantly quieter, and the homeowner reports 36% lower cooling costs.
Installed a Mitsubishi ductless multi-zone system (model MXZ-3C30 with 3 zones) for a converted garage ADU in a Parktown home. The homeowners needed efficient climate control for their aging parents without expensive ductwork modifications. The new inverter-driven system provides independent temperature control, operates whisper-quiet, and handles Milpitas' heat efficiently.
