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

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.
San Rafael's FlexPath code for existing single-family homes awards the most points for a heat pump space heater. The city's grid utility is PG&E, with generation from MCE.
Larger remodels of pre-2011 homes must reach a target score from the city's measure menu. A heat pump for space heating earns more points than any other single measure.
MCE lists heat pump HVAC incentives. Terms change, so confirm eligibility with MCE.
Eichlers with radiant floors usually suit ductless or slim-duct systems. Ranch homes with working ducts can often take a ducted heat pump after a duct check.
