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 Sunnyvale Eichlers, ADUs, additions and hot rooms. HAXX plans head placement, circuits and permits for single and multi-zone systems.
Serving Cherry Chase, Ortega Park, Lakewood Village, Ponderosa Park, Fairbrae and the Heritage District and the rest of Sunnyvale. Share your address to confirm availability.

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.
Sunnyvale has about 1,100 Eichler homes across Fairbrae, Rancho Verde and the Cherry Chase tracts. With no attic for ducts, ductless heat pumps are the natural way to add cooling.
Wall, ceiling cassette or slim-ducted heads suit post-and-beam rooms. Line sets are routed to keep the exterior clean.
A single-zone heat pump on its own circuit heats and cools a backyard ADU or garage conversion.
SVCE and City of Sunnyvale heat pump rebates can apply when a mini-split replaces gas heating. Confirm current terms.
