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 Sonoma homes often have little room for ductwork. Mini-splits add heating and cooling room by room without major demolition.
Line sets and outdoor units are placed to keep facades near the Plaza tidy. Wall, floor or ceiling cassette heads fit different rooms.
A single-zone heat pump on its own circuit heats and cools a backyard unit year round.
