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.
Split-level hillside houses, Old Town cottages and floating homes rarely have space for ducts. Ductless heat pumps heat and cool room by room without opening walls.
Homes stacked down a slope often need separate zones per floor. HAXX sizes each head to the room and its view-window heat gain.
Line sets are run through closets, under decks or in covered exterior chases to protect them from weather and salt air.
Single-zone heat pumps work well in ADUs, studios and in-law units on their own circuit.
