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.
  • Energy Efficient: DC Inverter and 22 SEER for high efficiency.
  • Smart Controls: Smartphone app controls and compatibility with Alexa and Google Home.

REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
Size: 8, Color: Black Patent
I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.

Love these flats!
Size: 9 Wide, Color: Black White Faux Snake Skin, Size: 9 Wide, Color: Black White Faux Snake Skin
One of my favorite pair of flats! I’ve had these for several years and they are still comfortable, in good shape and really add a little spice to my outfits. I can wear these all day and not have any foot pain or discomfort as a result. The quality is good, fit is perfect and I tend to have difficulty with shoes due to bunions. Love these!!

I love these shoes so much I had to write a review. So comfortable. Cushioned. Fits perfectly especially if you are more on the wide side. They are soft. Flexible. Easy slip ons you can walk around in all day. I want to try more colors.

Great buy
Size: 12 Wide, Color: Black Faux Leather
I absolutely love these Amazon Essentials Belice Ballet Flats! They are so comfortable right out of the box and fit my feet perfectly. I can wear them all day without my feet hurting, which is hard to find with flats sometimes. They’re also really cute and go with almost everything I wear. I find myself reaching for them all the time because they’re both comfy and pretty. Definitely a great everyday shoe, especially for the price!
