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.
Upstairs bedrooms in two-story homes often run warmer than the rest of the house on summer afternoons. A ductless head solves that without touching the main system.
A wall-mounted head on its own zone cools a bedroom or bonus room the central system cannot keep up with.
A single-zone heat pump on a dedicated circuit heats and cools a garage conversion or backyard unit.
HAXX plans the outdoor unit location and line-set path to keep side yards clear and the exterior neat.
