Ductless heating
and cooling.
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.
No ducts needed
A small line set connects each head to the outdoor unit through a wall opening, so there is no duct work to run.
Single or multi-zone
One outdoor unit can serve one room or several, depending on the layout and loads.
Head placement
Wall, ceiling cassette or concealed ducted heads, chosen around furniture, windows and looks.
Electrical and condensate
Dedicated circuit, disconnect and a clean condensate route planned before the install.
Permits
Mechanical and electrical permits and the city inspection handled by HAXX.
LOS ALTOS DETAILSMini-split installs
Mini-split installs
in Los Altos.
Additions, finished basements and backyard ADUs are common on Los Altos lots, and they rarely tie into the main ductwork well. Ductless heat pumps handle them on their own.
01
Basements and additions
A dedicated zone keeps a basement or second-story addition comfortable without overworking the main system.
02
ADUs
A single-zone heat pump on its own circuit heats and cools a detached ADU or converted garage.
03
Brand choice
HAXX installs Mitsubishi Electric and American Standard systems in wall, ceiling cassette and slim-ducted styles.
