The 4th Generation MRCOOL DIY Ductless Heat Pump System is a powerful single-zone system. The system has a condenser, air handler, and a 25 ft. line set pre-charged with R-410A refrigerant. The line set also has quick connectors, which require no special tools, equipment, or training to install. The MrCool DIY system also includes many features that make it stand out among its competitors. The first is its ability to achieve up to a 22 SEER efficiency rating allowing it to be Energy Star certified. This system has many operating modes to suit the user's needs, including HEAT, COOL, DRY (dehumidification), and SLEEP. It also has the Follow Me function that adjusts the room's temperature based on the temperature being read by the hand-held remote control.
