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.
We point you to the rebates your address qualifies for and provide the equipment documentation programs ask for.
Palo Alto runs its own gas and electric utility, City of Palo Alto Utilities (CPAU), so rebates and service upgrades come from the City rather than PG&E. The rules on noise and placement are local too.
CPAU lists a rebate for heat pump HVAC that replaces gas heating, with a higher amount for income-eligible households, plus add-ons for panels, circuits and permit fees. Check current terms on the CPAU Rebate Hub.
Palo Alto offers an instant permit to C-20 contractors for heat pump systems in detached single-family homes, duplexes and ADUs, with a calculated setback and a noise limit for the outdoor unit.
The instant permit excludes outdoor units on the roof or visible from the street. HAXX plans the condenser location around setbacks and noise before quoting.

CPAU offers a heat pump HVAC rebate when the system replaces a gas or other fossil fuel heater, with add-on rebates for panel upgrades, new circuits and permit fees. Amounts change, so confirm on the CPAU Rebate Hub before you sign.
Many single-family and ADU projects qualify for the City's instant heat pump permit, which requires a load calculation, equipment specs and a CF1R form. Projects that do not qualify go through a pre-application.
Yes. Bay Area winters are mild, and correctly sized heat pumps heat comfortably through them. Sizing and duct condition matter more than the brand.
Most single-system replacements take one to three days on site. Permits, equipment lead times and any electrical work add to the overall timeline.
