Load calculation and sizing
Equipment is sized to the house, not to the old furnace label. Oversized systems short cycle and cost more.

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.

Keep existing ducts when they are in good shape, or go ductless where ducts are missing, leaky or impossible to run.
HAXX electricians review the panel and service before the install, so a surprise panel upgrade does not appear mid-project.
Mitsubishi Electric and American Standard systems, among others, matched to the home and budget.
HAXX pulls the mechanical and electrical permits and meets the city inspector.
We point you to the rebates your address qualifies for and provide the equipment documentation programs ask for.
Pinole runs an Instant Residential Energy Permitting portal through Symbium for gas-to-electric HVAC swaps, which can shorten the permit step. Sizing and electrical capacity still decide how the project goes.
The City lists instant permits for gas-to-electric and electric-to-electric heat pump and mini-split replacements. Gas-to-gas swaps go through eTRAKiT instead.
For AC units and heat pumps, the City asks for a site plan showing the outdoor unit location and CF1R Title 24 forms. HAXX prepares them with the application.
Pinole has listed a limited-time rebate that may cover building permit fees for qualifying heat pump installs at 1 to 4 unit properties. Confirm current terms with the City.

Yes. Bay Area winters are mild, and correctly sized heat pumps heat comfortably through them. Sizing and duct condition matter more than the brand.
Most single-system replacements take one to three days on site. Permits, equipment lead times and any electrical work add to the overall timeline.
