MRCOOL DIY Multi Zone 5th Gen 55K BTU Four Zone Ductless Mini Split with Ceiling Cassettes 9K + 12K + 12K + 18K – A Heating and AC System You Can Install By Yourself!

MRCOOL DIY Series Ceiling Cassettes provide efficient heating and cooling while remaining out of sight and discreet, making them a perfect fit for any space. The cassette features an easy, low profile installation and can be recessed between all types of joists on 16 inch center including pre-manufactured I-joists. This makes it a perfect option for both new construction or retrofits. It doesn’t have strict installation requirements like other ceiling cassettes, so you’re able to install it in the location that suits you best, without using ductwork or wall space. The cassette works with the MrCool® DIY® Quick Connect® line set and the No-Vac® Coupler to increase the length of the line set. Not only does the unit offer quiet operation and multiple operating modes, but it also features the Elevation function that lowers the filter panel for easy air filter maintenance. Purchases of the MrCool® DIY® Series 9K, 12K, and 18K BTU Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

The MRCOOL DIY 5th Gen 4-Zone 55,000 BTU 22 SEER2 (9K + 12K + 12K + 18K) Ductless Mini Split System with Ceiling Cassette units are super easy to install and require no special training or expensive specialty tools. The DIY system includes Quick Connect lines that are pre-charged with eco-friendly R-454B refrigerant. Due to the Quick Connect line set, you don’t have to hire an HVAC technician to complete the install. We also have simple video instructions on how to install a DIY Multi-Zone unit yourself!

The MRCOOL DIY Multi-Zone 55,000 BTU 22 SEER2 4 Zone Ductless Mini Split System - 9K + 12K + 12K + 18K can cool through the Summer, heat through the Winter, and dehumidify through the wet seasons. Plus, you can quickly check the temperature of each room in your home from the easy to read digital display or from the MRCOOL Smart Controller mobile app. The display on the front of each indoor air handler unit can also display troubleshooting codes and alerts, so you are always aware of any issues with your system. Operate each unit wirelessly with either the included remote or with the MRCOOL Smart Controller app for Apple or Android devices. You also have the ability to control your mini-split unit with Amazon Alexa or Google Home.

The four MRCOOL DIY Multi-Zone air handlers included in this set provide directional control of the heated or cooled air. This distributes the air evenly so everyone in the room can stay comfortable. If you are in a situation that requires forced cooling, you can set your MRCOOL DIY System to manual with the button located on the right side of the unit under the front panel. In this emergency operation mode, you can test the cooling operation of your unit after installation or to complete a maintenance task.

In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed. You can also set this system to a drying function, which will continue to control the space’s air temperature while dehumidifying.

Use the sleep mode at night to save money on your utilities bills and use less energy. Sleep mode operates in an 8 hour window once turned on.

The MRCOOL DIY Multi-Zone 55,000 BTU 22 SEER2 Four-Zone Ductless Mini Split Air Conditioner System - 9K + 12K + 12K + 18K comes with many options, so you can customize your system based on your needs. Limit your energy usage and save money on your utility bill by using the system’s timer function. If your system begins to run low on refrigerant, an alert will appear on the easy-to-read display on the front of each air handler, letting you know there may be a leak. If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off. Should the unfortunate event of a power outage occur, the MrCool system will automatically shut off and then back on with the same settings once power returns.

Easily maintain your MRCOOL DIY Multi-Zone 55,000 BTU 22 SEER2 Four-Zone Ductless Mini Split Air Conditioner Unit with alerts and reminders. Any troubleshooting codes will appear on the front display and the user manual contains an index for common codes. Air filter cleaning alerts are automatic, and you can easily keep the minimal indoor units clean with a dry or damp cloth.

Small caddy that makes a big difference
Color: Black
I don't have counter space to spare, so having a dedicated spot for my sponges, dish brush, and soap right at the sink has been really convenient. Everything is corralled and easy to grab. The angled design drains directly into the sink, which keeps things from getting gross and waterlogged. There's a separated sponge compartment which I like, and it's big enough to hold a couple of sponges, a long dish brush, and a small bottle of dish soap all at once. It also just looks way nicer than my previous solution of stuffing everything into a jar. It's sturdy, hasn't gotten rusty or tarnished, and it just feels well made. Sometimes a small organizational upgrade makes your whole kitchen feel better and this is one of those. Also, very reasonably priced! For $11, this is a goodie.

Works well, spacious
Color: Black, Color: Black
Quality: This holder is actually really nice. It feels sturdy and well made, not flimsy or cheap at all. The material has a solid feel to it, and it holds everything in place without tipping or sliding around. Size and Capacity: This thing is bigger than I expected in a good way. There is plenty of space for multiple sponges, scrubbers, and even a small bottle of dish soap without everything feeling crammed together. It also has a removable compartment specifically for longer dish brushes, which is really convenient. It keeps them upright and separate so they are not just laying across everything else. Use and Functionality: The functionality is great. It is very easy to use and keeps everything organized and in one spot instead of scattered around the sink. One of the best parts is the drainage. Any excess water drains right back into the sink, and I have not had any issues with water pooling at the bottom. That alone makes a big difference in keeping things cleaner and less messy. Overall, It looks good, feels good, and does exactly what it is supposed to do. Good quality, very functional, and worth the price. Definitely a solid kitchen sink organizer.

Every kitchen needs one of these!!!
Color: Black, Color: Black
Whoever designed this is absolutely brilliant!! I have had so many sponge holders that either sit on the edge of the sink and make a big huge mess or they’re attached to the inside of the sink with suction cups and they fall off and they get in the way. This one is absolutely perfect. It has a little tray built-in on a slant so when you set your sponge or whatever in there, the water runs down back into the sink. No more water puddling on the sink running onto the counter. This drains it right back in the sink automatically I am thrilled with this sponge holder !! It’s a nice color and very well-made. It’s metal but the drain tray is a hard plastic , which is fantastic because then it won’t rust. I am all about making things in life easier and this sponge holder not only looks great , it will eliminate cleaning up messes off the side of the sink. I posted a picture with water running into the sponge holder and it shows how the water runs down into the sink… It holds various sizes of sponges. It’s got a little area for a brush .I have a couple of my smiley sponges ( no names mentioned ) that fit in there perfectly.. every kitchen should have one of these without a doubt!!!
