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.
One heat pump covers Benicia's hot summer afternoons and cool winter nights. The right size depends on the house, insulation and duct condition.
HAXX runs a load calculation instead of matching the old unit's size, which avoids short cycling and uneven rooms.
Older downtown houses often suit ductless heads. Tract homes in Southampton and the hills usually take a ducted system on existing ducts after a duct check.
