Room-by-room comfort

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.
Atherton lots often hold more than one building. A mini-split heats and cools a detached cottage, studio or pool house without running ducts across the property.
A single-zone heat pump on its own circuit suits a guest house, office or pool house.
Tudor and Colonial homes in Lloyden Park and West of the Alameda can take wall, ceiling or slim-ducted heads where ducts are hard to add.
