Load calculation and sizing
Equipment is sized to the house, not to the old furnace label. Oversized systems short cycle and cost more.

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.
Concord gets its electricity generation from MCE, with PG&E delivering it. MCE has its own heat pump rebate, and Concord's heat means cooling capacity matters as much as heating.
Concord has hit 113 degrees on record. HAXX runs a load calculation so the system keeps up during a September heat wave without being oversized.
MCE lists up to $400 per 500 square feet of home for heat pump heating and cooling, through contractors listed in its Contractor Finder. Confirm current terms and eligibility with MCE before you sign.
Concord takes mechanical and electrical permit applications through its Accela-based ePermit Online portal. HAXX prepares the permit application and is on site for the inspection.

MCE offers a heat pump rebate to eligible customers in owner-occupied single-family homes. It cannot be applied after installation, so confirm eligibility with MCE before work starts.
MCE's terms say you cannot add other electrification projects, such as solar, batteries or EV charging, for 12 months after the heat pump is installed. Plan the order with that in mind.
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.
