Mini-splits heat and cool rooms without ductwork. They fit homes with no ducts, additions, ADUs, garages and the hot room the central system never reaches.
Each indoor head has its own thermostat, so bedrooms, offices and living areas can run at different temperatures.
A small line set connects each head to the outdoor unit through a wall opening, so there is no duct work to run.
One outdoor unit can serve one room or several, depending on the layout and loads.
Wall, ceiling cassette or concealed ducted heads, chosen around furniture, windows and looks.
Dedicated circuit, disconnect and a clean condensate route planned before the install.
Mechanical and electrical permits and the city inspection handled by HAXX.
Cotati's ADU rules and its older homes near the Plaza make ductless systems a common fit. Each indoor head heats and cools its own zone.
A single-zone heat pump on its own circuit handles a backyard ADU or converted garage without extending the main house ducts.
Houses with wall heaters or no ductwork can add multi-zone heads instead of building new duct runs.
HAXX plans head placement, line-set routes and condensate drains so the outside of the house stays tidy.
