Each unit is designed to efficiently heat or cool areas between 376 and 500 square feet, making this system ideal for medium to large rooms or multiple smaller spaces. The multi-zone compatibility allows you to customize the climate in each zone independently, eliminating the need for ductwork and delivering targeted comfort exactly where you need it.
