Recent Furnace Repair Work in San Ramon

Here are examples of recent HVAC projects completed in San Ramon neighborhoods similar to yours:

Gale Ranch

Installed a Carrier variable-speed heat pump system (model Infinity 18VS with Infinity smart thermostat) in a 2,800 sq ft Gale Ranch home. The new 18 SEER2 system replaced a 14 SEER AC and old furnace, providing app-based control, superior humidity management, whisper-quiet operation, and reducing energy costs by approximately 42%. The tech-savvy homeowner appreciates the smart home integration and remote monitoring capabilities. The installation qualified for $2,200 in combined rebates.

Dougherty Valley

Replaced an undersized 13 SEER AC with a properly-sized 17 SEER2 Lennox variable-speed heat pump in a 2,500 sq ft Dougherty Valley home. The previous system struggled during San Ramon's hottest days. The new heat pump maintains consistent comfort even during 95°F heat waves, operates significantly quieter, and the homeowner reports 38% lower cooling costs and improved air quality.

Windemere

Installed a Mitsubishi ductless multi-zone system (model MXZ-4C36 with 4 zones) for a converted bonus room and home office in a Windemere home. The existing central system couldn't adequately serve the addition without expensive ductwork modifications. The new inverter-driven system provides independent temperature control, handles San Ramon's heat efficiently, and operates whisper-quiet-critical for video conferences and focused work.
