MRCOOL DIY Multi-Zone 5th Gen 55K BTU Five Zone Ductless Mini Split with Ceiling Cassettes 9K + 9K + 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.

The MRCOOL DIY 5th Gen Multi-Zone 55,000 BTU 22 SEER2 5 Zone Ductless Mini Split System - 9K + 9K + 9K + 9K + 12K is ideal for homeowners looking to efficiently cool and heat five rooms of varying sizes. The four 9K air handlers each cover up to 375 sq ft, while the 12K unit handles up to 550 sq ft—perfect for bedrooms, offices, and large living areas. 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.

MRCOOL DIY 5th Gen Multizone 55,000 BTU systems can support up to five indoor units—the maximum supported for this condenser.

Feel free to mix ceiling cassette air handlers and wall mounted air handlers together in a system by visiting Building Your Own Custom Mini Split System.

The MRCOOL DIY 5th Gen 5-Zone 55,000 BTU 22 SEER2 (9K + 9K + 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 - 9K + 9K + 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 - 9K + 9K + 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.

great dog toy for small and large!
Size: Medium (Pack of 1), Style: Gator
we have a very large silver lab that tears through toys, and very fast! some toys only last a day while others last a week or so... he has yet to tear this on up at all and we have had it for about 3 weeks. we also have a very small teacup yorkie, so some toys we get he cannot even play with, this one he can squeak and carry around which is great! it very quickly became one of their favorite toys! will buy again if he ever does destroy it !!! update: after a month of the lab and small yorkie playing with this some of the fabric stared to tear on the end of the toy, they still love it and it still squeaks perfectly fine. didn't think it would last this long with the big lab, will order new one when they do finally destroy it for good

A must have for my little puppers
Size: Small (Pack of 1), Style: Monkey
Bought this for a Chihuahua. He came from a bad situation that gave him screaming dreams of terror in the middle of the night, waking up, screaming. I would find him frozen in absolute terror. Poor dude. Now, he seems full of rage, and I get it because I know half of his story. And we love him anyway. He has 2 big brothers that will help show him the way, living his best life ever! Long story short; I first started buying this Petstages toy many years ago for my blind MinPin. Seeing it still, out here for sale always puts a smile on my face. Back then, they were a better quality. Now-a-days, the material around the squeaky is on the loose side, making it easier to destroy when my big dogs get it. Still, it brings back wonderful memories, is soft for a small dog that doesn’t destroy his things, it squeaks and they are usually loud (which is a must have, if you ask me), and it is cute to boot!

THE favorite toy
Size: 1 Count (Pack of 1), Style: Shark, Size: 1 Count (Pack of 1), Style: Shark
I found this toy used at a thrift store almost 1 year ago. My Shih tzu mix loved it so much till all the seams ripped out and 2 out of 3 squeekers fell out and it was shambles, hardly usable at all. 1 week ago I decided to try my luck to find a similar shark toy for Finnegan. I couldn't believe my eyes when I found THE EXACT same toy!! When I unboxed it, I put the old and new side-by-side and imagine his surprise, it was priceless! Very pleased with this.

Best Dog Toy Ever!
Size: Small (Pack of 1), Style: Monkey, Size: Small (Pack of 1), Style: Monkey
Unbelievable. See below previous reviews. Today is 3/22/2023 (4th Update): Cavachon is now three years old. THIS MONKEY is STILL played with DAILY. She’s played with and lost interest in dozens of other toys in the past three years, but Monkey is always the go-to. Now only on Monkey #6, which is remarkable considering the daily torture she puts Monkey through. Other toys get destroyed, but Monkey endures. This toy is our dog’s best friend and playmate! 10/9/21 (3rd update): Its rare that any toy (without food inside) keeps the interest of our Cavachon for even 30 minutes… yet day after day, she runs around with Monkey for at least an hour. She’s on her 4th Monkey… and this thing gets mauled, chewed, super-squeaked, fetched, and shook violently EVERY DAY. Durability times ten! 2/21/21 (2nd Update): Crazy pup is now 14 months old, and she plays DAILY with “monkey”! She’s on her third monkey because eventually she pulls off the tail, but each of her first two lasted months. ORIGINAL REVIEW MAY 2020: There is something really special about this monkey... Our 5-month-old Cavachon LOVES this toy. I recently ordered a second one, in case she wears out the first one. She knows it’s her “monkey” and finds it when we ask her “Where’s monkey?” She fetches it, walks around squeaking it, and she also zooms around the house shaking it furiously by the tail. She’s been playing with, and chewing on all parts of It, DAILY for three months. In the photo, you can compare the brand-new one, still on the cardboard, with the one she’s mauled for three months. Not much difference. I would say this is an extremely durable, and safe, toy.
