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.
Equipment is sized to the house, not to the old furnace label. Oversized systems short cycle and cost more.
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.
Pleasant Hill homes buy electricity from MCE, delivered over PG&E lines. MCE runs its own heat pump rebate, and the city's Building Division reviews mechanical and electrical work.
July highs average in the mid 80s and heat waves go well beyond. HAXX runs a load calculation for the house rather than copying the old unit's tonnage.
MCE lists up to $400 per 500 square feet for heat pump heating and cooling in owner-occupied single-family homes. Confirm current terms with MCE.
MCE's rebate rules bar adding solar, batteries or EV charging for 12 months after the heat pump. Confirm current terms with MCE.
