The MRCOOL DIY Multi-Zone 48,000 BTU 21 SEER 3 Zone Ductless Heat Pump Split System - 18K + 18K + 18K is the perfect way to heat or cool three separate rooms. With this system, no special tools or training are necessary - just a few simple steps and you can have the air comfort of your dreams. The 48,000 BTU capacity is more than enough to provide cooling and heating for up to 800 square feet. What's more, you're covered for up to 7 years for the compressor and 5 years for the parts, plus a lifetime compressor warranty.

Featuring Quick Connect lines that are pre-charged with eco-friendly R-410A refrigerant, you can install this system without the help of an HVAC technician. Plus, there are video instructions to guide you through the process. This unit can cool through the summer, heat through the winter, and dehumidify the air when necessary. You can even check the temperature of each room from the digital display or the MRCOOL Smart Controller mobile app.

This is a great option for those who need forced cooling. Manual operation is available with a single button located on the right side of the air handler unit. You also have the ability to control the mini-split unit with Amazon Alexa or Google Home. The air handlers also provide directional control of the heated or cooled air so everyone in the room stays comfortable.

The MRCOOL DIY Multi-Zone 48,000 BTU 21 SEER 3 Zone Ductless Heat Pump Split System also includes a sleep mode that can save you money on utilities when used at night. Furthermore, you can customize the system with a timer function and mute each indoor unit. If there is a power outage, the system will automatically turn off and then back on with the same settings once power is restored. Finally, the unit can alert you when the air filters need to be cleaned and it contains an index for troubleshooting codes.
