MRCOOL DIY Multi-Zone 5th Gen 36K BTU Three Zone Ductless Mini Split with Ceiling Cassettes 6K + 6K + 9K – 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 + 6K + 9K) 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 + 6K + 9K 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®!

One of the Most Useful Skincare Products I Own
Title: One of the Most Useful Products for Mature Skin — Smooths, Protects, and Works Beautifully Under Makeup At 52 with post-menopausal dry, mature skin, I’m always looking for products that don’t just sit on the surface, but actually improve how my skin looks and behaves throughout the day. This surprised me in the best way. This is not a treatment product, and it’s important to set that expectation upfront. This is a barrier-supporting, smoothing balm, and when you use it for what it is, it performs exceptionally well. The texture is where it really wins. It’s a solid balm stick, but it glides effortlessly without dragging or pulling on the skin, which is critical for more delicate, mature areas. It melts just enough on contact and leaves behind a smooth, lightweight, conditioned finish that feels nourishing without being greasy or heavy. From a formulation standpoint, this is built around silicones and emollients that give an immediate soft-focus effect, combined with oils and butters that help reinforce the moisture barrier. There’s also adenosine for long-term wrinkle support and collagen extract for conditioning, though this is not going to rebuild collagen or act like a corrective serum. What it does do extremely well is improve the appearance of the skin instantly. It softens fine lines, reduces that dry, crepey look that can show up midday, and adds just enough slip and hydration to make the skin look healthier and more refined. Where I really love this is under makeup. It creates a smooth, hydrated base that helps foundation sit better and prevents it from catching on dry areas. It doesn’t pill, it doesn’t break anything down, and it adds that subtle cushion that mature skin really benefits from. I’ve also used it over makeup for touch-ups, and it works just as well without disturbing what’s underneath. This has quickly become one of those products I keep within reach because it’s so practical. It’s not about transformation — it’s about maintenance, comfort, and immediate visual improvement, which, for mature skin, is often exactly what you need. No irritation for me, and it layers seamlessly with the rest of my routine.

Consistency is the key
This product is amazing. You have to keep in mind that it doesn’t give instant results. However, consistent use will reveal wonders. I use my whole stick before I started to see results. When my stick was gone, is when I looked in the mirror and I was shocked. My forehead was tighter and lifted. My under eye bags had disappeared, and my eyes looked tighter. My skin was just so youthful looking. So I was like OK!! I need to order another one, I swear I didn’t think it was working at all until the sticker was gone. And I just woke up one morning and noticed a huge difference. I wonder if the changes will last?

The balm stick needs to roll all the way to the top
Overall I like the product itself I think its very moisturizing and it does seem to help the appearance of wrinkles however I think for the cost its pretty wasteful in the application. The rollup stops and there is still a ton of product on the bottle. I had to dig it out with my finger for a good 2 weeks worth of product I dont understand why it doesnt roll all the way to the top..

Seems like it provides good coverage
Size: 6 Fl Oz (Pack of 1)
I am very much liking this for the sunscreen properties. It should be noted that your face will be white and it's hard to meld into your natural skin tones. However I'm more concerned with something that works

reliable everyday sunscreen
Size: 6 Fl Oz (Pack of 1)
this product goes on smoother than many mineral sunscreens I’ve tried and doesn’t leave an overly thick or greasy feeling on the skin. The protection lasts well during outdoor activities, and the water resistance makes it great for the beach, workouts, or long walks in the sun.
