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 cottages near Magnolia Avenue and canyon homes on hillside lots rarely have room for ducts. Ductless heads heat and cool one zone at a time.
One outdoor unit can serve several rooms. HAXX lays out heads, line sets and drains to keep runs short and tidy.
Larkspur offers pre-approved ADU plans. A mini-split is often the simplest way to condition a new unit without extending ducts.
HAXX installs the circuit, disconnect and any panel work under its electrical license on the same job.
