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 and homes without ductwork are common in El Cerrito. Ductless heat pumps condition each level or room without opening walls for ducts.
Separate zones for upper and lower floors stop the top of the house from overheating while the bottom stays cold.
El Cerrito recommends all-electric ADUs to skip a gas line and flue. A single-zone mini-split heats and cools the unit on its own circuit.
HAXX installs Mitsubishi Electric single and multi-zone systems, with line sets routed to keep the exterior neat.
