Room-by-room comfort
Each indoor head has its own thermostat, so bedrooms, offices and living areas can run at different temperatures.
Mini-splits for Petaluma Victorians, ADUs, additions and rooms that never get comfortable. HAXX plans head placement, circuits and the city permit.

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.
Many Queen Anne and Eastlake houses on the west side were never built for ducts. Ductless heat pumps add heating and cooling without opening walls and ceilings.
Wall, floor or ceiling cassette heads, with line sets routed to keep visible exterior work small. In historic districts, HAXX accounts for design review.
A single-zone heat pump on a dedicated circuit heats and cools a backyard unit on its own.
SCP sets separate SEER2 minimums for single-zone and multi-zone ductless systems. HAXX selects equipment that qualifies.
