MRCOOL DIY Multi-Zone 5th Gen 55K BTU Five Zone Ductless Mini Split with Ceiling Cassettes 6K + 6K + 9K + 9K + 12K – 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 centers, 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 Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

This system combines high performance and flexibility with DIY-friendly installation, so you can skip the HVAC crew and save thousands on labor. Everything is powered by a robust 55K BTU condenser, backed by a 7 Year Compressor Warranty (with optional lifetime coverage) and a 5 Year Parts Warranty.

The MRCOOL DIY 5th Gen 5-Zone 55,000 BTU 22 SEER2 (6K + 6K + 9K + 9K + 12K) 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 5 Zone Ductless Mini Split System - 6K + 6K + 9K + 9K + 12K 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 five 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 Five-Zone Ductless Mini Split Air Conditioner System - 6K + 6K + 9K + 9K + 12K 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 Five-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.

To be fair this is the worst side the other side is about an eighth of ...

I used to work at big box store some twenty years ago and there were two selling points for Sauder furniture at the time. The furniture was 3/4 inch particle board and ease of construction. Well neither of those are the case any longer. I am putting this together and the L brackets that Sauder provides are of the adjustable variety. This lets one slide the two wooden pieces so to obtain a match on their edges. Well in theory, in reality one cannot slide them far enough so one has a 1/4 inch mismatched edge. On part H which is a horizontal trim piece. It is not long enough to cover the trim pieces edges that are below it in the vertical. Those edges are raw wood, but do not worry Sauder has been kind enough to include a brown magic marker so I will be able to cover up that raw wood. I included a photo of one side. To be fair this is the worst side the other side is about an eighth of an inch. And to be even more fair, there should not be any raw wood showing. It is not very sturdy either, the only thing that makes it from really wobbling is the fiber board backing at the rear of the bookcase. My expectations when I bought this piece of furniture was not that great. I wanted to buy a piece of furniture that was fairly easy to put together. I also wanted a piece of furniture that looked okay. This piece of furniture achieved neither one, I would have been better off going to a second hand furniture store and buying a bookcase there. Even if I had to refinish the second hand bookcase it would of been less hassle then this thing. Oh, Sauder I do not want to see a response saying please contact us at 1-800 whatever. When do most people put this furniture together? I would hazard to guess the weekend. When is Sauder customer service open? I can tell you it is not the weekend. If you are thinking of buying this, I would think twice.

Perfect buy
Color: Classic Cherry, Size: L:29.80" x W:12.99" x H:71.26"
I absolutely love this bookcase. It’s stable. It has the perfect color. It’s the perfect height not too tall, but definitely not short. And if it’s perfectly in the corner of my room, the only issue I had with this is the assembly process. Definitely don’t recommend you assembling it on your own. Definitely having someone there to help you assemble it. It’s definitely something I would do. It stores a lot of books, but definitely follow the weight capacity. I didn’t follow the weight capacity and now I have slightly bent shelves. It has good stability.The value is fair for how long it lasts because I still haven’t and it’s still standing.

Difficult to assemble, low quality, but looks nice
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
It looks nice when finished, but it's a major pain to put together. I've assembled a lot of DIY furniture over the years, but this was one of the more frustrating ones, mainly because of the unnecessarily difficult way the finishing slats need to be attached. Also the frame was very unstable during assembly. This bookcase is also not exactly sturdy even when finished. It's a low-quality product in all respects, really, except the nice way it looks. Value for money? meh. Color is nice.

Excellent Customer Service. Follow instructions.
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
I LOVE the color of this bookcase. The bookcases at the big chain store generally cost around $100, so this is about what I was expecting. It's a nicer quality with thicker shelves than the big chain store bookshelves and I really wanted the cherry color, which, on this bookcase, is gorgeous. It was a bit difficult to assemble only because I asked for help from a male friend who insisted that we skip through the directions. We ended up getting a screw caught between two beams because he didn't want to sort out the screws like I ALWAYS do before assembling any furniture. Note: just breathe, relax and take your time and follow the directions, and if you ask for help from someone, give them a sedative, like a big dose of kava or something because it's going to take several hours. Once it's finished, though, it's really lovely. I filled it with books and so far, it's been fine. It is particle board with a finish, so if you scratch it, it's going to show. But, it comes with a brown color-coordinated marker so you can cover up minor scratches or flaws in the finish. I was a little surprised that the top of the bookcase is unfinished, but maybe a lot of bookcases are not nowadays. I wouldn't put it in a location where the top of it shows - like next to a staircase. The backboard is cardboard folded in half with the same cherry finish, which for me really wasn't an issue because I always fill my bookcases completely with books so the back doesn't really show. There are weight restrictions for each shelf, so make sure you pay attention to those - some shelves hold more weight than others. I plan to assemble the second one by myself now that I understand what's involved. I have to give five stars because customer service was so amazing. I didn't open the second bookcase for a long time, but despite the time that had passed, they still replaced a damaged beam very quickly, and even reshipped the beam a second time because I had given the wrong address. That was really amazing! Never had such a good experience with customer service before.
