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.
In Dixon the cooling load usually sets the size of a heat pump, not the heating load. A proper Manual J calculation keeps the system from short cycling in mild weather.
HAXX calculates load room by room, accounting for west-facing glass, attic insulation and duct condition common in Dixon tract homes.
Mechanical and electrical permits are filed through the City of Dixon's online permit portal, which also handles plan review, fees and inspection scheduling.
HAXX installs American Standard ducted systems and Mitsubishi Electric ducted and ductless heat pumps.
