Load calculation and sizing
Equipment is sized to the house, not to the old furnace label. Oversized systems short cycle and cost more.
Ready to retire a gas furnace or worn-out AC in Moraga? HAXX matches a heat pump to the house, checks the panel and files the county permit.

A heat pump replaces a furnace and AC with one system for heating and cooling. Good results come from sizing, layout and electrical planning done before equipment is ordered.

Keep existing ducts when they are in good shape, or go ductless where ducts are missing, leaky or impossible to run.
HAXX electricians review the panel and service before the install, so a surprise panel upgrade does not appear mid-project.
Mitsubishi Electric and American Standard systems, among others, matched to the home and budget.
HAXX pulls the mechanical and electrical permits and meets the city inspector.
We point you to the rebates your address qualifies for and provide the equipment documentation programs ask for.
Two local facts shape the project: MCE supplies Moraga's electricity and offers heat pump rebates, and Contra Costa County, not the Town, issues the building permit.
MCE's heat pump heating and cooling rebate scales with square footage and can pair with its water heater rebate. It applies only to equipment not yet installed, so confirm eligibility with MCE first.
Moraga homes tend to be larger than the Bay Area average. A room-by-room Manual J and a duct inspection set the size, not the tonnage on the old furnace label.
The county building division takes Moraga applications through its ePermits Center. Both mechanical and electrical permits are filed by HAXX, which also attends the inspection.

MCE lists rebates for heat pump heating and cooling and for heat pump water heaters, with ownership and timing rules. Rebate amounts and rules can change, so confirm eligibility with MCE before any contract is signed.
No. Contra Costa County's building division permits and inspects Moraga projects, and HAXX takes care of the filing.
Yes. Bay Area winters are mild, and correctly sized heat pumps heat comfortably through them. Sizing and duct condition matter more than the brand.
Most single-system replacements take one to three days on site. Permits, equipment lead times and any electrical work add to the overall timeline.
