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.
SAN MATEO DETAILSHeat pump installs
Heat pump installs
in San Mateo.
San Mateo's 2026 reach code took effect in April 2026 and sets efficiency rules for replacement HVAC in single-family homes. WestLight Energy (formerly Peninsula Clean Energy) adds rebates when a heat pump replaces gas heat.
01
What the reach code asks
When a whole system is replaced, the city's code calls for duct, airflow and refrigerant checks for an AC, and limits backup strip heat on heat pumps. A properly sized heat pump is often the simpler path.
02
WestLight Home Upgrade Rebates
WestLight Energy lists a per-unit rebate for heat pump HVAC that replaces a gas furnace, with a bonus for income-qualified customers. Dual-fuel systems with gas backup do not qualify. Check current terms.
03
Homes of every era
Baywood and San Mateo Park homes often have basement or attic ducts that can take a ducted unit. Eichlers usually get ductless or slim-ducted heads.

GOOD TO KNOW
Heat Pump Installation in San Mateo: questions, answered.
What rebates are there for a heat pump in San Mateo?
WestLight Energy offers Home Upgrade Rebates for heat pump HVAC that replaces gas heating, paid first come, first served. Amounts can change, so confirm with WestLight before signing.
Does the rebate need a permit?
Yes. WestLight asks for the city permit with the application. 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.
