The 12,000 BTU ductless inverter unit will heat, cool, and dehumidify an area of up to 550 sq. ft. It's a quiet, efficient and convenient way to keep your home consistently comfortable any time of the year be it in the winter or the summer, regardless of the outdoor temperature. The fan silently produces even temperatures throughout the covered area. The variable compressor (DC inverter) provides efficient operation to meet the heating and cooling needs of your home. It is perfect for anyone that does not have central air conditioning and for people that do not want to settle a noisy, insecure and sometimes inadequate AC window unit. It's a great solution for when adding a room, replacing zonal electric heat, or those hard to reach areas such as an upstairs room or attic.
