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.
Many Oakland houses predate ducted heating, or have ducts too small for cooling. Mini-splits heat and cool without opening walls for new ductwork.
Line sets can be routed to keep exterior changes small on Victorians and early-1900s houses in West Oakland and Rockridge.
Split-level hill homes often have rooms that a single system cannot reach. Separate zones keep each level comfortable.
A single-zone heat pump on its own circuit suits a backyard ADU, garage conversion or in-law unit.
