Load calculation and sizing
Equipment is sized to the house, not to the old furnace label. Oversized systems short cycle and cost more.
Swapping a Richmond gas furnace or old AC for a heat pump? HAXX sizes the system to the house, reviews the panel and pulls City of Richmond permits.

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.
Richmond's climate is mild year-round, with September usually the warmest month, so a right-sized heat pump can handle both heating and cooling. Sizing matters more than extra capacity.
HAXX sizes equipment from a room-by-room load calculation, not the old furnace's rating, so the system runs efficiently in Richmond's moderate climate.
Older Richmond homes often have smaller panels. HAXX checks service size and circuit space during the estimate.
Mechanical and electrical permits go through the City of Richmond Building Division. Electrification rules have shifted since the federal court ruling against Berkeley's gas ban, so confirm current requirements with the City.
