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.
Central systems in two-story Brentwood homes often leave upstairs rooms several degrees warmer. A ductless head fixes one room without reworking the ducts.
A single-zone head cools a west-facing bedroom or bonus room on its own schedule.
A mini-split on its own circuit suits a new ADU or converted garage. The city reviews ADUs as new residential permits.
HAXX installs single and multi-zone Mitsubishi Electric systems, with line sets routed neatly along the exterior.
