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.
Few Emeryville condos and lofts have room for ductwork. Ductless systems connect each room to an outdoor unit through a small line set, which suits concrete and timber-loft construction.
Wall heads, ceiling cassettes or slim-ducted units are chosen around exposed beams, brick and tall windows.
HAXX routes line sets to minimize visible exterior work and plans the outdoor unit location for HOA approval.
Older houses without ducts and backyard ADUs can heat and cool room by room with single or multi-zone systems.
