Panasonic ducted and ductless advanced cooling and heating systems are perfect for additions, entire homes and problem rooms that are always too hot or too cold. Since 1958, Panasonic has evolved from window-type air conditioners to ClimaPure XE ductless heating and air conditioning systems with nanoe™ X – a built-in air purification technology that inhibits both airborne and adhered pollutants and odors in the home.
