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 9K and BTU Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

The DIY system includes Quick Connect lines that are pre-charged with eco-friendly R-454BA 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 27,000 BTU 23 SEER 4 Zone Ductless Heat Pump Split System - 9K + 9K + 9K + 9K 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.

The MRCOOL DIY Multi-Zone 27,000 BTU 23 SEER Four-Zone Ductless Heat Pump Split Air Conditioner System - 9K + 9K + 9K + 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 27,000 BTU 23 SEER Four-Zone Ductless Heat Pump 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
If you’re in need of comfort, our new 5th Generation MRCOOL® DIY® 27k BTU Multi-Zone Ductless Mini Split Condenser is the perfect solution! The acronym in the name is true - you can install this system on your own, without the assistance of an HVAC professional! You’ll save money in more ways than one, too, due to the incredible efficiency of this system, which attains a SEER2 rating of 23 and a HSPF2-4 rating of 9.5. This condenser in particular is able to support up to 4 air handlers, meaning it can provide heat and air conditioning to four separate spaces equalling a total of 1,000 to 1,200 square feet. This system is unique because it utilizes special, patented Quick Connect® line sets that are pre-charged with R-454B, which is a newer refrigerant that allows the system to be even more sustainable and efficient than its previous generation. These line sets essentially link to the fittings of the condenser and the air handler, making the installation process a breeze. These line sets are sold separately. Once installed, this condenser will be able to do more than you expect! Our SmartHVAC app gives you the opportunity to integrate the system with your phone and Amazon Alexa or Google Home, which will let you control your comfort using just your voice. The app also gives you the ability to customize your comfort with a range of features, from setting schedules to monitoring the system’s energy use. You deserve to have your comfort meet your standards, and this unit can do that for you. Should something happen to the system, we’ve got your back. The DIY® series boasts one of the foremost warranties in the HVAC industry - a 5 year parts warranty, a 7 year compressor warranty, and a Limited Lifetime Replacement warranty if you enroll in the MRCOOL® Care Program.

Lightweight, Glowy, and Perfect for Everyday Use ☀️✨
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
This sunscreen is my new favorite! It’s so lightweight and smooth, and it blends right into my skin without leaving any white cast or greasy feel. I love that it gives me that natural glow while still providing serious sun protection. The SPF 60 makes me feel confident spending time outside, and it wears beautifully under makeup or on bare skin. It doesn’t clog my pores or irritate my skin, and the formula feels hydrating instead of sticky. I’ve used it for workouts, beach days, and everyday errands, and it holds up perfectly through it all. My skin still feels soft and fresh at the end of the day. It’s perfect for anyone who wants to protect their skin while keeping that healthy, radiant look. I wore it for carnival and got compliments on my skin all day. This sunscreen is definitely a must-have in my daily routine! 🌞💛

A solid choice for those seeking effective sun protection combined with hydration.
Size: 1.7 Fl Oz (Pack of 1)
Neutrogena Invisible Daily Defense Face Sunscreen + Hydrating Serum is designed to offer broad-spectrum sun protection while providing hydration to the skin. Here's a detailed review of this product based on its features, performance, and user feedback: Pros: Broad-Spectrum Protection: This sunscreen provides broad-spectrum SPF 60 protection, which helps shield the skin from both UVA and UVB rays. This is crucial for preventing sunburn and long-term skin damage. Hydrating Formula: Infused with hydrating ingredients, this product acts as a serum, providing moisture and helping to keep the skin hydrated throughout the day. This is beneficial for those with dry or combination skin. Lightweight and Non-Greasy: Users often appreciate that the sunscreen has a lightweight, non-greasy texture. It absorbs quickly into the skin without leaving a heavy or sticky residue, which makes it suitable for daily use. Invisible Finish: The "Invisible" aspect of the sunscreen refers to its ability to blend seamlessly into the skin without leaving a white cast. This makes it suitable for various skin tones and types. Suitable for All Skin Types: Dermatologist-tested and designed to be non-comedogenic, it is generally safe for sensitive skin and won’t clog pores, reducing the risk of breakouts. Fragrance-Free: This product is fragrance-free, which is a significant advantage for those with sensitive skin or allergies to perfumes and artificial scents. Cons: Price: Neutrogena's products are often on the pricier side compared to some other drugstore sunscreens. While it offers added benefits, such as the hydrating serum, the cost might be a consideration for some. Size: The size of the product may be relatively small for its price, which can be a drawback for those who use sunscreen generously or frequently. Ingredient Sensitivity: While the product is designed to be suitable for sensitive skin, some individuals may still react to certain ingredients. Always check the ingredient list if you have known sensitivities. Hydration Level: While it does provide hydration, those with extremely dry skin may still need additional moisturizing products to maintain optimal skin moisture. Overall: The Neutrogena Invisible Daily Defense Face Sunscreen + Hydrating Serum is a solid choice for those seeking effective sun protection combined with hydration. Its lightweight, non-greasy formula and broad-spectrum SPF 60 make it a reliable option for daily use, especially if you prefer a sunscreen that blends invisibly into the skin. While it is on the higher end of the price spectrum and may not fully address extreme dryness on its own, its overall performance and benefits make it a valuable addition to a skincare routine.

One of the better American sunscreens
Size: 1.7 Fl Oz (Pack of 1)
One of the better sunscreens you can get in the U.S. for an affordable price. Neutrogena’s facial sunscreens can be a hit or miss, but this is their better ones. I’m used to using Asian sunscreens that feel like a light moisturizer or serum on the face so I’ve been spoiled. It’s nice to find an American sunscreen that is spf 50+ with no white cast that also feels lightweight, non-greasy, and doesn’t sting my eyes. This sunscreen fits the bill. I used four pumps of product to cover my face to get proper coverage. I could have used a little more tbh. The serum is a very light beige and a bit watery in texture. It blends out invisible as advertised. The finish is shiny and a little greasy looking at first, I’ll admit, but it dries down to a natural finish. I did use a Korean toner pad before applying the sun serum. The end result with the Neutrogena sun serum is a natural finish with a subtle healthy glow in 70 degree weather. It does sting my eyes when I sweat or exercise though. One star off for that. Also it does not pill under makeup.
