Room-by-room comfort
Each indoor head has its own thermostat, so bedrooms, offices and living areas can run at different temperatures.
Ductless mini-split installation in Fairfax for cottages, additions, ADUs and hot upstairs rooms, with head layout, circuits and Town permits planned.

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.
Older Fairfax homes often heat with a wall furnace or floor furnace and have no ducts. A mini-split heats and cools room by room with minimal construction.
Wall, ceiling cassette or floor console heads take over from wall and floor furnaces one room at a time.
A single-zone system on its own circuit suits a backyard unit, studio or garage conversion.
On a sloped lot the condenser may sit well below the house. HAXX routes, supports and protects the line set for that run.
