The MRCOOL DIY Multi-Zone 4th Gen 36K BTU Three-Zone Ductless Mini Split with ceiling cassettes (9K + 9K + 12K) is a versatile, energy-efficient heating and cooling solution you can install yourself without the need for professional help. Each ceiling cassette provides efficient heating and cooling while maintaining a low-profile, discreet presence, making them a perfect fit for any space. The cassettes are easy to install between joists (16-inch center, including pre-manufactured I-joists), offering flexibility for both new construction or retrofits.

These cassettes work seamlessly with the MrCool® DIY® Quick Connect® line set, along with the No-Vac® Coupler to extend the line set length as needed. This eliminates the need for wall space or ductwork. In addition to quiet operation, the cassettes feature the Elevation function, which lowers the filter panel for hassle-free filter maintenance.

This system includes two 9,000 BTU cassettes and one 12,000 BTU cassette, perfect for efficiently heating or cooling three rooms, with capacities to handle up to 375 sq. ft. and 500 sq. ft. respectively. The 36,000 BTU condenser enables the system to provide year-round comfort by delivering cooling in the summer and heating in the winter.

DIY Installation is made simple with pre-charged lines filled with eco-friendly R-410A refrigerant, so no need to hire an HVAC technician. Quick Connect lines simplify the installation process further, reducing time and costs. The system also supports up to four indoor units, allowing you to mix and match cassettes with wall-mounted air handlers, offering even greater customization for your home.

You can control your comfort through the MRCOOL Smart Controller mobile app, or integrate with Amazon Alexa or Google Home for voice-activated controls. The digital display on each indoor air handler provides real-time temperature readings and displays any troubleshooting codes, ensuring you're always in the know.

For your peace of mind, the system is backed by a 7-year compressor warranty, a 5-year parts warranty, and even an optional lifetime compressor warranty.

Key Features:

  • DIY Installation: Easy setup with no special tools required.

No way I’d give this five stars. And I struggled to give it four to be honest
Once it’s installed it looks great. As someone else had mentioned the instructions are pretty useless. This item comes with screws and wall anchors. If given the chance, install into studs or use different plugs. The ones provided are terrible. I wanted this shelf unit centered in the wall where it was hung. To do this, I had to use the anchors, and not really giving any thought to it, opted to use the ones provided. They flat out suck. So, I then opted to hang it off center into studs. I wish I had bought this item prior to doing some renovations because I would have installed some blocking in the walls, but it is what it is. So, in closing, I installed a 2-shelf version that does look nice once installed. The instructions are basically useless. If using wall anchors, find better ones. Choose to install into studs if possible.

This is incredibly difficult to get the holes lined up
We tried a few ways to install this. It was incredible difficult to get the holes lined up and the drywall screws were really poorly made- they went right through the wall. We were able to get 3/4 screws on each hole lined up. Better written instructions would have probably gone a long way.
