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.
Two-story homes in Livermore often have upstairs rooms that stay hot on summer evenings. A mini-split cools those rooms without reworking the central system.
A single head on its own outdoor unit fixes a hot bedroom or west-facing office.
Livermore accepts ADU permits online. A mini-split heats and cools a backyard unit or garage conversion on its own circuit.
Line sets are routed and covered to keep the exterior neat, and condensate is piped to a proper drain.
