This system can heat & cool an area up to 750 sq. ft and is capable of an ENERGY STAR certified 22 SEER efficiency rating.

This system comes equipped with many functions that separate it from the rest. It has multiple operating modes, which include AUTO, HEAT, COOL, FAN-ONLY, DRY (dehumidification), and SLEEP. It also features the Follow Me® function, which allows the system to continually adjust the room temperature based on where the handheld remote controller is located. Need to operate the system when you’re not at home? No problem. The MRCOOL® system also has the capability of being operated with your smartphone through the use of the Smart HVAC app. MRCOOL® stands behind the quality and workmanship of this system by offering a 7-year compressor and 5-year parts warranty, including eligibility for the MRCOOL® Care Program.
