Recent Heat Pump Repair Work in Walnut Creek
Here are examples of recent HVAC projects completed in Walnut Creek neighborhoods similar to yours:
Installed a Mitsubishi ductless mini-split heat pump system (MXZ-SM36 outdoor with wall-mounted indoor units) in a single-family home in the San Miguel neighborhood of Walnut Creek, CA. The new high-efficiency inverter system now heats and cools previously uncomfortable rooms and has reduced the family's PG&E bill by about 40% compared to their old electric heaters.
Replaced an older 80% gas furnace and AC with a high-efficiency, variable-speed 18 SEER2 cold-climate heat pump system sized for a 2,000 sq ft home using the home's existing ductwork in Northgate, Walnut Creek. The new system delivers more even temperatures, quieter operation, and qualified the homeowner for over $2,000 in Bay Area heat pump rebates plus federal tax credits.
Installed a compact side-discharge Carrier heat pump system (Carrier 37MURA Crossover Series, ideal for tight spaces and low-noise applications) for a downtown Walnut Creek condo with limited outdoor space. The slim outdoor unit fits neatly on a small patio, and the whisper-quiet, variable-speed operation keeps both the homeowner and close neighbors comfortable year-round.
