Ductless heating
and cooling.
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.
No ducts needed
A small line set connects each head to the outdoor unit through a wall opening, so there is no duct work to run.
Single or multi-zone
One outdoor unit can serve one room or several, depending on the layout and loads.
Head placement
Wall, ceiling cassette or concealed ducted heads, chosen around furniture, windows and looks.
Electrical and condensate
Dedicated circuit, disconnect and a clean condensate route planned before the install.
Permits
Mechanical and electrical permits and the city inspection handled by HAXX.
