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.
HERCULES DETAILSPlanning a heat pump
Planning a heat pump
in Hercules.
Hercules has a mild climate, with July highs averaging in the low 70s, so a properly sized heat pump handles both seasons with room to spare. Mechanical and electrical work both need a City permit.
01
Sizing for a mild climate
Oversized equipment cycles on and off in a climate like this. HAXX runs a load calculation room by room instead of matching the old furnace size.
02
Permit and inspection
The City of Hercules requires permits for mechanical and electrical work, and every permit includes an inspection. HAXX applies and meets the inspector.
03
Utility programs
PG&E delivers power in Hercules and MCE is the default electricity provider. MCE lists electrification rebates; confirm eligibility directly with MCE before you buy.

GOOD TO KNOW
Heat Pump Installation in Hercules: questions, answered.
Do I need a permit for a heat pump in Hercules?
Yes. Mechanical and electrical work requires a permit from the City of Hercules, and the work is inspected. HAXX handles the application.
Which heat pump brands does HAXX install?
HAXX installs American Standard ducted systems and Mitsubishi Electric ductless and ducted heat pumps, chosen to fit the home.
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.
