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.
CLAYTON DETAILSHeat pumps for
Heat pumps for
Clayton homes.
Clayton gets its power from PG&E rather than a community choice supplier, so rebates come from state and regional programs. Cooling capacity matters here as much as heating.
01
Sized for Clayton heat
Clayton has recorded summer highs above 105 degrees. HAXX runs a room-by-room load calculation so the heat pump keeps up without being oversized.
02
Incentives to check
Clayton is not in MCE's service area. The state TECH program reported its funds fully subscribed in February 2026, so confirm what PG&E, state and BayREN programs offer before you sign.
03
Permits through the County
Clayton contracts with Contra Costa County's Building Inspection Division. HAXX prepares the application, holds the required Clayton business license and attends the inspection.

GOOD TO KNOW
Heat Pump Installation in Clayton: questions, answered.
Which rebates apply to a heat pump in Clayton?
Clayton is served by PG&E, not MCE, so look to state and regional programs. State TECH funds were reported fully subscribed in February 2026; HAXX can help you check current options.
Does Clayton require a permit for a heat pump?
Yes. Replacing a furnace or air conditioner needs a building permit. Clayton's permits and inspections are handled by Contra Costa County's Building Inspection Division.
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.
