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.
MONTE SERENO DETAILSPlanning a heat pump
Planning a heat pump
in Monte Sereno.
Monte Sereno's 2026 reach code targets new construction and exempts replacement of existing appliances, so a heat pump in an existing home is your choice, not a mandate.
01
SVCE incentives
Silicon Valley Clean Energy serves Monte Sereno and lists instant rebates on heat pump HVAC through its home upgrades program, while funds last. Confirm terms before you sign.
02
Gas furnace timeline
Bay Area Air District rules end sales of new gas furnaces from 2029. Repairs are not affected, but planning ahead avoids a rushed replacement.
03
Matched to the house
Eichlers on Via Sereno often suit ductless or slim-duct systems. Larger homes with attic or crawlspace ducts can take a ducted heat pump after a duct check.

GOOD TO KNOW
Heat Pump Installation in Monte Sereno: questions, answered.
Does Monte Sereno require a heat pump when I replace my furnace?
No. The city's reach code applies to new construction and does not apply to replacement of existing appliances. Heat pumps are still eligible for SVCE rebates.
Who pulls the permit for a heat pump in Monte Sereno?
HAXX submits the application through the city's ePermits site and meets the building inspector for the final.
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.
