MRCOOL DIY Multi-Zone 5th Gen 36K BTU Three Zone Ductless Mini Split with Ceiling Cassettes 6K + 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 36,000 BTU 23 SEER2 3 Zone Ductless Mini Split System is ideal for homeowners looking to efficiently heat and cool three rooms with larger square footage. With its DIY-friendly design, this system allows you to install everything yourself without the need for special tools or HVAC training. The included 36K BTU condenser powers the entire system and is 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.

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 3-Zone 36,000 BTU 23 SEER2 (6K + 9K + 12K) Ductless Mini Split System with Ceiling Cassette units is easy to install and requires no special training or expensive specialty tools. The DIY system includes Quick Connect lines that are pre-charged with eco-friendly R-454B refrigerant. Thanks 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 36,000 BTU 23 SEER2 3 Zone Ductless Mini Split System 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 three 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 Three-Zone Ductless Mini Split Air Conditioner System – 6K + 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 36,000 BTU 23 SEER2 Three-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! For the best comfort you’ve ever felt and a sense of accomplishment as icing on the cake, choose the MRCOOL® DIY®!

Pretty gold tone color and works well
Color: Gold
This is great for lazy people like myself. Just pull back the grabber hand and drop the paper towels in, no unscrewing anything or fiddling around, I only want to spend one second installing my paper towels and this lets me do that. The gold tone works well with my decor, it has a very finely brushed gold tone metal finish trending into brass color tones that looks better in person than in the listing. Overall it looks very high end. The bottom is very heavily weighted, paper towels slip right on, and removing a towel with one hand is a snap. The grabber hand keeps the towels in place. On the bottom are 4 very effective grabby strips that keep the unit from sliding. The whole unit weighs 3 pounds but somehow it seems like it's a lot more. Checking over the listing, it looks accurate other than some of the photos make it look a little less golden than it really is. This thing is so nice. I was going to use this at work but it might be too nice looking for an industrial environment so I'll probably just use it at home instead. The downsides on this are there were a few super tiny scratches that you'd really have to squint to see. You probably would not notice but still not ideal. The other obvious issue is these are currently priced at $50. Looking around at other options, I don't see many with all the features of this unit including upscaled finish, smoothly operating grabby hand, and heavily weighted bottom but certainly there are many other towel holder options that get good reviews for less money so I would not say this unit is the best economic bang for the buck. However if you really don't care about an extra $20 or you would really like an upscale nice brushed gold/brass finish, then it might be well worth it for you because this does work really well and I am very much enjoying it.

Solid Investment
Color: Stainless Steel, Color: Stainless Steel
At first I thought this was a little expensive for a paper towel holder, but after using it for a few days, I completely understood the price. It’s very sturdy and honestly delightfully functional in a way that basic holders just aren’t. The spring-loaded arm works really well and actually allows easy one-handed tearing without the whole thing tipping or unraveling. A few things I liked: Weighted base keeps it firmly in place Non-slip bottom works well on countertops Spring arm holds the roll securely and makes tearing easier Stainless steel finish looks clean and modern Feels much sturdier and better made than cheaper versions A couple minor things: The arm is a little stiff at first, but loosened up slightly with use Larger/thicker rolls can fit tightly until some paper is used Overall, I think it’s a really good value for the money and performs exactly as advertised. One of those kitchen items that seems simple, but once you use a better-designed version, you definitely notice the difference.

This is the one!! The only paper towel holder I will ever have in my home.
Color: Stainless Steel, Color: Stainless Steel
I don’t usually get this excited about a paper towel holder... but THIS IS EXACTLY WHAT I’VE BEEN LOOKING FOR!!!! Seriously. I’ve gone through so many flimsy, annoying holders that slide around, lift up, scrape the counter, or make that awful squeaking noise when you try to tear a sheet, and this one fixes every single one of those problems. The weighted base is EVERYTHING. It’s heavy enough that it doesn’t move at all when you pull a paper towel. No sliding. No tipping. No lifting. It just stays put like it’s supposed to. And the non-slip bottom means it doesn’t scratch or drag across your counter, which is such a huge plus. The spring-loaded arm is genius. You can actually tear a paper towel one-handed without fighting the roll or having it unravel everywhere. It keeps just enough tension so you get a clean tear every time. The design is sleek and practical. The stainless steel finish looks clean and modern, and it fits nicely with any kitchen style. It’s simple, but in a way that feels very intentional and well thought out. I’m not exaggerating when I say this is the only paper towel holder I will ever buy from now on. I already want to get more for other areas of the house and this is the only kind of paper towel holder I will ever buy for my family and friends. Nothing comes close to how good this one works. If you’ve ever been annoyed by your paper towel holder, then look no further than this!! It solves all the little everyday frustrations and makes something simple actually work the way it should. Conclusion: Love it, love it, LOVE IT!! It is worth every penny!!! 🙌 Yes, it's a tad expensive for a towel holder, but it is THE BEST and absolutely worth it!!

Good Product, Fair Price
Color: Gold-aa
I bought this for my guest bathroom where I have some other brass items and it fits right in. Easy assembly with the supplied Allen wrench and bolt, and it comes with a cover for the bolt hole which perfectly matches the base padding material so the assembly point becomes invisible. It doesn’t have a ‘towel unroll preventer’ but I knew that when I evaluated the reasonable sale price and decided that wasn’t important for the intended use. The base is heavy and the assembled item seems very sturdy. I found it weird that this towel holder came with a plastic box containing a fork and a spoon as a ‘gift’ but this will go in my car camping cookware bag. I don’t know how the brass finish will hold up over time but for now I’m very pleased.
