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.
Upstairs rooms in two-story San Marco and Vista Del Mar homes often run hotter than the rest of the house. A ductless head fixes one room without reworking the central system.
A single-zone mini-split cools a bedroom or bonus room that the central system cannot reach well.
Wall-mounted or ceiling cassette heads add cooling and heating to older Old Town houses that never had central air.
A dedicated mini-split on its own circuit serves a backyard ADU or converted garage.
