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.

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.

Campbell does not require existing homes to give up gas heat, so a heat pump is a choice here. Campbell is a Silicon Valley Clean Energy member city, which opens the door to SVCE rebates.
SVCE lists a rebate for a heat pump that replaces a gas furnace, plus separate rebates for panel and circuit work and an income-qualified adder. Check current amounts with SVCE before signing.
Campbell's local code amendments have called for HERS testing of all ductwork when 25 feet or more of new duct is installed. HAXX confirms what applies when it plans the job.
Many Campbell homes are 1,000 to 1,600 square feet. A room-by-room load calculation keeps the system from being oversized.
