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.
  • Pre-Charged Quick Connect Line Set: Simplifies installation without the need for refrigerant handling.
  • Multi-Room Comfort: Two 9,000 BTU cassettes and one 12,000 BTU cassette, ideal for rooms of various sizes.

Didn’t live up to the hype.
I had high hopes for this product. I’ve seen it all over social, but for me it didn’t live up to the hype. Although it is very moisturizing, it never dries down. There’s no way I could apply makeup over this, as the ads might lead you to believe. If you want a good night time moisturizer then this product is for you.

No Good
So I got this under the impression by the videos online that this was really concealing under the eye and it’s not…very oily and hasn’t done anything for under my eyes at all! Scam!

Not your regular under eye patches
Im in love with these under eye patches. These are not your regular under eye patches. My eyes look refreshed and hydrated. I often keep them on all day and i love the tightening effect after they dry down. My under eye feels firmer and looks plumper. Sometimes i will even wear them overnight. They are very cooling. I love that they are clear so not very visible on zoom meetings. For all that it does, it is definitely worth the hype and the price.
