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 gas furnace or aging AC for a heat pump in Santa Rosa? HAXX sizes it, checks the panel and handles the city permit SCP rebates require.

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.
Sonoma Clean Power lists a rebate for qualifying heat pumps and a larger one for hydronic systems that also heat water. Rebates require a finalized permit, so the paperwork matters as much as the install.
SCP sets minimum SEER2 ratings that differ for ducted, single-zone ductless and multi-zone systems. HAXX selects equipment that clears them. Dual-fuel systems do not qualify.
SCP excludes new construction from its rebates but makes an exception for fire rebuilds, which matters in Coffey Park and Fountaingrove.
Ranch homes in Bennett Valley and near the Junior College often have old ductwork. HAXX inspects it and recommends sealing or replacement only where needed.
