Load calculation and sizing
Equipment is sized to the house, not to the old furnace label. Oversized systems short cycle and cost more.

Heat pump installation,
planned properly.
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.
Ducted or ductless
Keep existing ducts when they are in good shape, or go ductless where ducts are missing, leaky or impossible to run.
Electrical capacity check
HAXX electricians review the panel and service before the install, so a surprise panel upgrade does not appear mid-project.
Brands we install
Mitsubishi Electric and American Standard systems, among others, matched to the home and budget.
Permits and inspection
HAXX pulls the mechanical and electrical permits and meets the city inspector.
Rebate paperwork
We point you to the rebates your address qualifies for and provide the equipment documentation programs ask for.
FOSTER CITY DETAILSPlanning a heat pump
Planning a heat pump
in Foster City.
Foster City has not adopted its own electrification reach code and follows the state codes it adopted for 2026. Heat pumps are a choice here, and WestLight Energy (formerly Peninsula Clean Energy) pays rebates when one replaces gas heating.
01
Rebate for replacing gas
WestLight Energy lists a rebate per heat pump system that replaces a gas furnace or heater, plus a panel upgrade bonus. It asks for the city permit and proof the gas unit was decommissioned. Confirm current terms.
02
HOA approval
Many homes sit in Planned Developments. Some HOAs set rules for where an outdoor unit goes and how it is screened, so HAXX gets the approval letter before ordering equipment.
03
Over-the-counter permit
Foster City lists heat pump installation among its over-the-counter building permits. HAXX can also file through the city's eTRAKiT portal.

GOOD TO KNOW
Heat Pump Installation in Foster City: questions, answered.
Does Foster City require a heat pump when I replace my furnace?
No local rule requires it. Foster City paused its reach code effort and follows the state codes. The Foster City Building Division can confirm what applies to a given job.
What does WestLight Energy need for a heat pump rebate?
A copy of the city permit naming the upgrade, an itemized invoice, and proof the gas equipment was decommissioned, filed within the program deadline. Confirm eligibility with WestLight Energy.
Can a heat pump heat my house on cold nights?
Yes. Bay Area winters are mild, and correctly sized heat pumps heat comfortably through them. Sizing and duct condition matter more than the brand.
How long does an installation take?
Most single-system replacements take one to three days on site. Permits, equipment lead times and any electrical work add to the overall timeline.
