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.
VALLEJO DETAILSPlanning a heat pump
Planning a heat pump
in Vallejo.
Vallejo is milder than inland Solano County but less shielded from heat waves than San Francisco or Oakland. A heat pump covers winter heat and those hot stretches with one system.

GOOD TO KNOW
Heat Pump Installation in Vallejo: questions, answered.
Is a permit required for a heat pump in Vallejo?
Yes. The City of Vallejo lists HVAC systems among work that requires a permit. HAXX files it through eTRAKiT and schedules the inspection.
Which code applies to a new heat pump in Vallejo?
Permits applied for after January 1, 2026 follow the 2025 California codes, including the Energy Code. Confirm project specifics with the Building 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.
