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.
HILLSBOROUGH DETAILSDuctless systems
Ductless systems
in Hillsborough.
Large Hillsborough lots often carry pool houses, studios and converted garages, and main houses often have rooms that the original ducts never served well. Ductless heat pumps solve both.
01
Outbuildings
A single-zone heat pump on its own circuit heats and cools a pool house, studio or gym without extending ducts.
02
Problem rooms
Sunrooms, bonus rooms over garages and upstairs suites get their own head and thermostat.
03
Clean installs
Wall, ceiling cassette and slim-ducted heads, with line sets routed to protect finishes and exterior details.
