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.

GOOD TO KNOW
Heat Pump Installation in Colma: questions, answered.
Do I need a permit for a heat pump in Colma?
Yes. Heat pump installs are permitted through the Town of Colma Building Division and inspected before sign-off. HAXX handles the application and inspection.
Can a heat pump replace my gas furnace?
In most homes, yes. A heat pump heats and cools, and the Bay Area Air District plans to limit sales of new gas furnaces from 2029.
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.
