MRCOOL DIY Multi-Zone 5th Gen 36K BTU Five Zone Ductless Mini Split with Ceiling Cassettes 6K + 6K + 6K + 6K + 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 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 6K 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.

With four 6K air handlers (ideal for rooms up to 250 sq ft) and one 18K air handler (up to 750 sq ft), this system delivers precision climate control throughout your home. The DIY-friendly design means you can install it yourself without any special tools, training, or professional assistance. The system is powered by a 36K BTU condenser and comes backed by a 7 Year Compressor Warranty (with optional lifetime coverage) and a 5 Year Parts Warranty.

MRCOOL DIY 5th Gen Multizone 36,000 BTU systems can support up to five indoor units—the maximum supported for this condenser.

The MRCOOL DIY Multi-Zone 36,000 BTU 23 SEER2 5 Zone Ductless Mini Split System - 6K + 6K + 6K + 6K + 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 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 36,000 BTU 23 SEER2 Five-Zone Ductless Mini Split Air Conditioner System - 6K + 6K + 6K + 6K + 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 36,000 BTU 23 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.

LONG DESCRIPTION
The brand new 5th Generation MRCOOL® DIY® 36k BTU Multi-Zone Ductless Mini-Split Condenser is the right choice if you need immediate, effective comfort that won’t break the bank! This system, which can be installed without the assistance of an HVAC professional, is one of the most efficient and innovative HVAC options on the market. With this condenser, you’ll be able to heat and cool up to 5 different spaces equaling around 1,500 square feet, meaning you can potentially heat and cool an entire home with just one mini-split system! Our DIY® Mini-Splits are able to forgo the evacuation and charging process because our patented Quick Connect® line sets are pre-charged with R-454B refrigerant, a more efficient and eco-friendly refrigerant than R-410A, which we have previously used. These line sets are sold separately. This unit achieves a SEER2 of 23 and an HSPF2-4 of 9.9. These fittings make installation an incredibly safe and simple process, allowing you to save a lot of time and money. There are a variety of features to explore once the system is up and running. One of them is the ability to integrate your system with the SmartHVAC app, allowing you to control your comfort with the touch of a button. You can even go a step further and link your Amazon Alexa or Google home for touchless operation. With the app, you can set each zone’s temperature, set schedules for each unit, monitor your system’s energy usage, and more. There are even more features to explore that will help you customize your comfort to be exactly what you want. We’ve got your back in the unlikely event that your system malfunctions. Your system will come with a 5 year parts warranty and a 7 year compressor warranty, and if you enroll in the MRCOOL® Care Program, you’ll be able to enjoy the Limited Lifetime Replacement warranty!

very strong for puppies with strong jaws.
Color: Brown-O, Color: Brown-O
I have a five month old puppy and she was having very bad teething. I know every puppy goes through it and it's usually a nuisance because they chew shoes or things that you don't want them to chew. This puppy would find a plastic coat hanger and try to chew it with her back teeth. I think she was cutting her molars and it was hurting her. She wasn't eating and she was drooling and whining. I felt so bad for her. She was trying to chew anything that could reach back to her back teeth. This product really helped her because it got back there and it is really strong. She is a Pitbull puppy and she already has a really strong jaw so a coat hanger didn't last long. This Teething ring did help and it got her through the worst of it. I really like it for that reason. If you have a teething puppy this is the right way to go. It doesn't squeak and it has a flavor that kept her coming back to it but the it didn't have a funky smell when she left it around like hooves or bully stick do. It also has a bumpy, rough surface that must have felt good on her gums.

Durable, fun, and good for aggressive chewers
Color: grass-green
I have bought this toy for my dog twice now, and the first time I purchased it, it quickly became his favorite. Unfortunately, I lost the first one when some other dogs took it down the street while we were playing outside. It was a bit heartbreaking to lose it, but after about two weeks, we managed to find the old one. However, it was in the middle of the street and had been run over several times, resulting in a broken squeaker. Despite its rough condition, it was clear how much my dog loved that toy. When I bought the new one, I was relieved to see that he doesn’t let it out of his sight at all. We have so much fun together, playing with it by throwing it in lakes, sandy areas, and engaging with other dogs. Even after all this rough play, the new toy is still intact. My dog particularly enjoys the squeaker feature, which adds to his excitement during playtime. He is an aggressive chewer, but this toy has proven to be more durable and has lasted us much longer than most of the other toys we've tried. It has definitely become a staple in our playtime routine!

Nope, not for Murphy the alligator hunter! 🐊🙄
Color: grass-green, Color: grass-green
Murphy, our 75 pound lab, loves to chew. We can’t give him anything soft or even anything remotely made for casual play as he chews them to pieces- literally. So when I saw this cute little alligator, with fairly good reviews, I bought it with high expectations. Nope. It didn’t have a chance- It’s in the garbage. ☹️ First I have to comment on the eyes. I don’t know what they are made of, but the “whites” of the eyes pealed off like paint within the first few minutes Murphy had it. He wasn’t even chewing at the eyes; they just pealed off. I can’t imagine that is good for dogs to ingest, but ok, I threw the white pieces away, and gave it back to him. I do have to say that he loved chewing on it- even without adding any kind of treat to it. So we watched him chew at it for about 30-40 minutes without it being dissected into a million different parts. I was impressed.... Until I took it away from him to be played with later.... during this time he was able to tear parts of the mouth (see pictures), and while all pieces are still in tact, I cannot imagine another 30 minutes of him having this in one piece. So, while I’m very aware that Murphy has limited toys to chew on, I will continue my search for indestructible toys for his chewing pleasure.

Cute toy maybe not for aggressive chewers
Color: grass-green
I bought this because I have an 3 1/2 yr old golden doodle. She tears every toy apart within half hour of having it. The only toys she hasn’t is Kong toys. This is a cute toy. She was shredding pieces off the rubber with half hour of chewing it:( I thought it was very similar to the material of Kong toys? She loves chewing it and playing with it but I probably would not buy it for really aggressive large dogs who tear up toys.
