Load calculation and sizing
Equipment is sized to the house, not to the old furnace label. Oversized systems short cycle and cost more.
Swapping a Newark gas furnace or aging AC for a heat pump? HAXX sizes the system to the house and checks the electrical panel before ordering equipment.

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.
Newark's summers are mild by Bay Area standards and winters rarely freeze, which suits heat pumps well. The bigger questions are usually ducts, panel capacity and the permit.
Newark's Building Inspection Division lists heater and AC installations and replacements among projects that do not require plans. A permit is still needed.
Many 1960s and 1970s Newark homes have attic or crawlspace ducts. HAXX checks duct size and condition so a ducted heat pump moves enough air.
Ava Community Energy supplies Newark's electricity and runs an online incentive finder. Look up current heat pump offers there and with BayREN before you sign.

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.
