Room-by-room comfort
Each indoor head has its own thermostat, so bedrooms, offices and living areas can run at different temperatures.
Need heating and cooling in a Pinole home without ducts, or in one hot room? HAXX installs single- and multi-zone ductless mini-splits.
Serving Old Town, Shale Hill, Pinole Valley and the neighborhoods off Appian Way and the rest of Pinole. Share your address to confirm availability.

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.
Old Town Pinole still has Queen Anne cottages and 1910s to 1920s bungalows, and many later homes have converted garages or additions. Ductless systems fit these well.
Cottages and bungalows near downtown rarely have room for ducts. Wall, floor or ceiling cassette heads heat and cool without opening walls for ductwork.
A single-zone unit can serve a bedroom, office or converted garage that the central system never reached.
HAXX installs Mitsubishi Electric ductless systems, sized per zone, with clean line-set routing outside.
