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.
Oakland has no rule forcing existing homes off gas, and the city is still developing its electrification roadmap for existing buildings. Most owners switch when a furnace or AC wears out.
Many pre-war Oakland homes have small or leaky ducts, or none. HAXX checks them first and suggests ducted, slim-ducted or ductless based on what it finds.
The city lists TECH Clean California, BayREN and California Energy Smart Homes for heat pump incentives, and Ava's Incentive Finder sorts them by household. Confirm terms before you sign.
Bay Area Air District rules will limit sales of new gas furnaces starting in 2029. Repairs are not affected, but it is worth planning for.

No. Oakland's existing-building electrification policy is still in development. The Air District's 2029 rule covers sales of new furnaces, not furnaces already installed.
HAXX applies through Oakland's Online Permit Center for the mechanical and electrical work and is there for the inspection.
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.
