Single-zone split air conditioners are quiet, efficient solutions for cooling, particularly if you don’t have central AC or access to an exterior wall. Each mini-split single-zone air conditioner is equipped with an air handler that mounts on a wall inside your home and a condenser unit that is stationed outside. This design allows ultra-quiet operation, since the condenser noise is outside—away from you indoors. These ductless air conditioners work fast to reach your ideal room temperature and don't lose power in cracked or leaking duct pipes. Ideal single-zone ductless air conditioner applications include home additions, historic buildings, garages, and any room without existing ductwork. Compared to standard central AC systems, single-zone mini-split air conditioners are more efficient and cost less to install.
