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.
CALISTOGA DETAILSPlanning a heat pump
Planning a heat pump
in Calistoga.
Calistoga homes face hot, dry summers and cool nights, so a heat pump has to be sized for both. Older homes on Cedar Street and near Pioneer Park often need a duct or panel review first.
01
Sized for real heat
Afternoon highs above 90 degrees are common in summer. HAXX runs a room-by-room load calculation rather than matching the old unit's tonnage.
02
Older homes, small lots
Craftsman and Victorian-era houses near downtown often lack attic space or garages, so ductless or compact ducted systems are planned around the house.
03
Electricity provider
MCE supplies electricity for Napa County, with PG&E delivering it. MCE and PG&E list their own customer programs; confirm eligibility directly with them.

GOOD TO KNOW
Heat Pump Installation in Calistoga: questions, answered.
Is a permit required for a heat pump in Calistoga?
Yes. Heat pump installs need mechanical and electrical permits from the City of Calistoga. HAXX pulls the permits and is present for the inspection.
What heat pump size does a Calistoga home need?
It depends on insulation, windows, sun exposure and ducts. HAXX calculates the load for your house instead of guessing from square footage.
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.
