The MRCOOL DIY Multi-Zone 36,000 BTU 23 SEER2 4 Zone Ductless Mini Split System - 12K + 12K + 12K + 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 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.

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 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.

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!

So far. so good.
Color: White
This is my 3rd frother that I purchased from Amazon. The others were brand name frothers that broken within a few months of use. I won't name here (hint: begins with an N and ends with an o) This Milk frother from Maestri however works excellent. Multiple heat and drink settings and makes the perfect foam every time. I especially like how the pitcher is removable from the electric base and can be washed with out worry. easy to use. Just read the manual to understand all the settings, makes a perfect froth in less than 2 minutes. I've only had this for a few weeks but I am impressed.

Loving it so far!
Color: White, Color: White
02 Nov 2025 I've only used this twice and I already love it. My main reason for buying it is for protein hot chocolate I drink twice a day. I previously made it at the stove and that took 13 minutes of constant mixing to reach 160°. My hot chocolate is 1 cup of milk, 1 tbsp each cacao powder and panela (sugar), 1-2 tbsp collagen powder, vanilla extract, and 1 whole egg. I premix everything before pouring it into the frother because, while it may be able to handle the powders, there's no way that whisk will be able to break the whole egg enough to thoroughly blend it before it starts cooking. I'm totally fine premixing the night before and heating it in the morning. I made the first batch this morning with 2 cups of milk doubling only the cacao and sugar which brought it to just below the top max line, and it came out perfect. It was smooth and there was no burnt taste. I used the recommended hot chocolate attachments, lowest froth setting, and 160° temp setting. I had almost no froth in my hot chocolate which was perfect. I removed the pitcher as soon as it was done to prevent any burning. I checked the temp with a thermometer and the temp was actually 165°. I don't really know if that would impact the taste if there was less milk. For the 2 cups, it was still perfect. I do wish there was a little more temp control like a 150° or 155° setting. I also wish it was able to give you the temp as it was heating in case you want to pull it off just before it hit the set temp. The bottom right button is superfluous. It helps with the foam setting, but you can also simply press each of those buttons directly. Cleaning is super easy, just remove the pitcher and attachments. I love that the attachments are magnetic, but I recommend taking them out before pouring because the magnets aren't that strong. All in all, great for the price and perfect for my needs.

Epic. Works great.
Color: Black
Works great every day. Super powerful and smooth compared to my old battery powered one. The shaft is much thicker and is more securely positioned so I can't imagine it becoming tweaked off balance like my old one. And it comes with an extra mixer attachment! I imagine I've put that away for a long time, but we'll see. Easy to turn on and off with one hand, but I can imagine it being less easy than a simple push button for someone with decreased thumb dexterity or mobility. I do wish the lowest speed was slightly lower, but it hasn't caused any splashing or other detriment. The speed adjustment is very smooth and power is abundant. Love the stand, Usb c charge port is solid, battery life is excellent.

You want this one, for power and quality and saving on AA battery costs
Color: Black
Yes. You want this one, for power and quality and saving on AA battery costs — buy it now. Don’t waste any more time comparing products. After hours, days, weeks, of researching and comparing, I ordered this one. I do not regret it. It is powerful. It was less than $25 when I bought it. It has a USB charger port and it feels solid in your hand. It has a turn-knob at the top to control the variable speed immersion blender aka milk frother aka wand frother. Charge battery fully for 2hrs before first use and then you’re all set. It works very well. It functioned as expected and then even better. Yes. It exceeded expectations. I hope it lasts a long time. It feels like it is very well made and high quality. Classiest and best wand frother I have ever owned. And I’ve owned over 3-4 in the past 10yrs. I got this one at $25 instead of the highest-rated one for $9.99 because those require AA batteries and this frother however is USB-C rechargeable! So in 1-2 years it will have paid for itself in battery costs alone. But there’s no price I can put on how enjoyable it is to use this super powerful, super smooth, high quality, wand frother.

Quality Design
Color: Gray
Excellent frother/mixer Pros: - Quality feels premium. - Plenty of power to mix even with a drink packed with ice and peanut butter. Basically a mini handheld mixer. - Ease of use is great. I appreciated that this had a longer brother so I can mix drinks in taller cups. Also the grip is fantastic and it is easy very easy to change the speed with just one hand so you can hold the drink with the other. Longevity - So far it's been holding up and hasn't needed a battery replacement. Cons: None so far.
