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.
A heat pump can replace both a worn AC and a gas furnace in one system. In Rio Vista the cooling load drives the sizing, so HAXX starts with a room-by-room calculation.
Equipment is chosen to hold capacity on the hottest afternoons, not just average days, so the house stays comfortable through a heat wave.
Rio Vista is not on MCE's list of member communities, so PG&E supplies electricity here. Ask PG&E about current heat pump rates and programs before you sign.
The City of Rio Vista takes building applications through its online portal or by email. HAXX prepares the mechanical and electrical paperwork and meets the inspector.
