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.

Great value: These are my go-to work from home shirt
Material Type: Recycled Polyester, Color: Blue, Size: X-Large
I’ve been pleasantly surprised by these shirts and wear them weekly for Zoom calls, since I’m still working from home these days. I figured at the price point it was worth trying them out, and now I’ve bought several in different colors. They aren’t super soft, but they are comfy and look nice. I’m 6’1” ~220 pounds, and the XL slim fit still has plenty of room. I imagine the regular cut is incredibly boxy and oversized. The difference between polyester vs recycled polyester is inconsequential. I typically buy expensive golf shirts, and these definitely aren’t as nice. They are a fraction of the cost though and a great “beater” work shirt / hang out shirt. It’s nice wearing something that looks and feels decent, but if something happens to it, you can toss and it and pick up another for the cost of a chipotle burrito.

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.
