MRCOOL DIY Multi-Zone 5th Gen 48K 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 48,000 BTU 22 SEER2 3 Zone Ductless Mini Split System is ideal for homeowners looking to heat and cool three large zones with a system that’s easy to install and built to last. The powerful 48K BTU condenser supports up to five zones, so you can add additional air handlers later if needed. The entire system is backed by a 7 Year Compressor Warranty (with optional lifetime coverage) and a 5 Year Parts Warranty.

MRCOOL DIY 5th Gen Multizone 48,000 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 48,000 BTU 22 SEER2 (6K + 9K + 12K) Ductless Mini Split System with Ceiling Cassette units are super easy to install and require no special training or expensive specialty tools. The DIY system includes Quick Connect lines that are pre-charged with eco-friendly R-454B 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 48,000 BTU 22 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 48,000 BTU 22 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 48,000 BTU 22 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.

MRCOOL® 48k DIY 5th Generation 6 Zone Multi-Zone Mini-Split Condenser 230v
LONG DESCRIPTION
We’re excited to introduce our new 5th Generation MRCOOL® DIY® 48k BTU Multi-Zone Ductless Mini-Split Condenser, because it’s better than its predecessor in nearly every way. You won’t need the services of an HVAC professional when you’re setting this unit up, because you can do it yourself, which saves lots of time and money! This condenser enables you to heat and cool up to 6 separate spaces equalling up to 2,000 sq. ft., meaning you’d be able to cover an entire home in the completely efficient comfort of a single DIY® system. You can install this system on your own because our innovative, patented pre-charged Quick Connect® line sets allow you to skip the lengthy and complicated process of evacuating and charging the system. These line sets are filled with R-454B refrigerant, a much more ecological and proficient upgrade from the previous refrigerant used in the last generation. This switch helps the system achieve impressive efficiency levels, like 21.8 SEER2 and an HSPF2-4 of 10. These line sets are sold separately. Once you install your system, you’ll be able to explore the variety of ways you can customize your comfort. For ultimate control, you can integrate system operations with the SmartHVAC app, available for Apple and Android phones, allowing you the ability to set schedules, manage modes of operation, monitor your systems all with the touch of a button. The app even enables you to set up integration with Amazon Alexa and Google Home, meaning you won’t have to move a finger to make your home more comfortable than ever. We pride ourselves on having one of the best warranties in the industry on this unit! Once you install your condenser, you’re entitled to a 5 year parts warranty, a 7 year compressor warranty, and, if you subscribe to the MRCOOL® Care Program, a Limited Lifetime Replacement warranty. The MRCOOL® DIY® is the right choice if you want fast, efficient comfort that won’t let you down!

Good for acne prone sensitive skin
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I am in my 30s with combo leaning oil and acne prone fair skin with pigmentation issues and I’m on prescription tretinoin every day. I sometimes use hydroquinone when my pigmentation issues flare up. I wear sunscreen every single day to protect my skin. It’s especially important since I’m on Tret. daily. Being that I have acne prone skin finding a sunscreen has always been a HUGE challenge for me. I’ve spent so much time on SkinSort and similar sites looking through sunscreen ingredients lists trying to find ones that won’t break me out. I’ve purchased PLENTY of k-beauty, j-beauty, EU sunscreens and Us sunscreens from Sephora and drugstore only for them to break me out. My skin is very sensitive/breakout prone to long ingredients lists, emollients, heavy textures, oils and lots of botanicals. I randomly stumbled upon this banana boat sunscreen here on Amazon and saw the short and fairly simple ingredient list that is low (not free of- but low) in occlusive ingredients in comparison to other sunscreens so I decided to order it. It has not broken me out and it feels nice. No alcohol in it, no irritation, no pimples so far. The tube is user friendly, the texture is light and pleasant and the sunscreen is affordable and accessible. I also appreciate how it’s water resistant so can be worn every day OR pool/beach. I highly recommend this to anyone with acne prone or sensitive skin if you are ok with US chemical sunscreens. I prefer chemical sunscreens over mineral sunscreens as mineral sunscreens break me out. This affordable banana boat in my opinion is WAY better for me personally than high end and expensive options that have tons of pore clogging ingredients. Yes even the popular k-beauty sunscreens break me out unfortunately. Everyone is different and anything has a potential to clog someone but for me this sunscreen is way more safe for my acne prone skin than any other sunscreen option I’ve come across. The majority of sunscreens are just packed with pore cloggers, but this banana boat one is minimal in comparison. The tube is travel size (tsa approved) but bigger than your standard 1.7oz sunscreen. This is nice for me because like I mentioned I wear sunscreen every single day and re-apply if I’ll be outside in the sun. While spending time outside I did not burn while wearing this sunscreen and I’m extremely fair skinned. I also did not notice any new pigmentation issues. The texture is nice, light and pleasant. It wears well under makeup. I normally wash my face in the AM, apply a hydrating kbeauty toner, tiny little dots of super light gel moisturizer (not much- I’m oily!) and then apply this banana boat sunscreen on top. Sometimes I wear makeup sometimes I don’t. It works both ways. I have not experienced any pilling. I have not noticed any scent with this sunscreen other than the sunscreen filters smell which isn’t too bad at all in comparison to other sunscreens I’ve tried. The sunscreen itself adds a touch of moisture but I don’t find it to be greasy on my oily skin. In the summer I will probably use a hydrating toner or serum (skip gel moisturizer) and then apply the banana boat sunscreen since I live in a warm climate. Anyways, this is a very nice textured non offensive not overly clogging (for me at least) Us chemical sunscreen that has been very unproblematic for me. I just apply a decent amount every AM and don’t even think about it. Like I mentioned if I’m out in direct sunlight (normally I’m not in the winter) I’ll reapply as needed. In the PM I use bioderma micellar water and then follow it with my Remedy brand face cleanser and it takes the banana boat off fine. I’m interested in trying the spray version (always spray decent amount into hand and then apply!) for my body in the summer. For now I apply this banana boat sensitive face to my face, neck, hands or whatever exposed area. If you tried the banana boat light as air face spf that one is a little more matte and dry but it’s also more pore clogging in both my experience and by ingredients lists. This banana boat sensitive has a bit of a different texture that’s lightweight and still not greasy but it’s more of a traditional light lotion. The banana boat light as air face one felt great but over time gave me more closed comedones. Needless to say I highly recommend this lightweight Us chemical sunscreen to anyone looking for a simple waterproof Us chemical sunscreen that is affordable and easy. Obviously no white cast as its chemical. Sorry for the long review but it might help someone out. Also I purchased this with my own money I am not a part of one of those product reviewing groups- whatever they are called. No shade to anyone lol.

Great
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
The sunscreen itself is really good. It applies smoothly just as advertised “lotion”. I was pleased to see it didn’t leave a white cast. I apply makeup over my sunscreen often. This sunscreen worked perfectly with makeup. Like it said, it’s unscented and that was true as I didn’t detect a scent. My skin feels nice with this on. My only issue is that it didn’t come with a safety seal under the cap. Usually all products come with a seal to ensure it isn’t tampered with and that buyer gets the full amount of product. That was a bit upsetting but hopefully I didn’t actually get a used one.

I LOVE this sunscreen!! Super affordable and lightweight for your skin!
Size: 6 Fl Oz (Pack of 1), Style: SPF 50
I love this sunscreen!! Love it so much I bought 3 bottles of it! Super lightweight and blends right into the skin, and I don’t feel not sticky! I got super excited and got this primarily because it’s lightweight, super affordable, SPF 50 for high protection, and it said there’s no alcohol or fragrance…heres the catch tho, there IS a slight sunscreen smell, but you only notice it when applying it and if you keeping smelling it on yourself up close during the day. Other than that, it’s truly fragrance free in the sense that you aren’t just standing there doing your thing, and keep getting HIT with the scent of sunscreen for hours, like other sunscreens! The scent is extremely light and pleasant when you go to smell it on yourself. Don’t EVER discontinue this please please please!!!!

It’s great! So light weight!
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I have been testing this out for a month now. I love it. This does have avobenzone in it, and because of that, I do NOT put it around my eyes as avobenzone is a chemical sunscreen ingredient that typically tends to cause the of sensation of burning eyes! At least for me it does. I use an Australian sunscreen around my eyes that doesn’t have anything that irritates my eyes. So for the rest of my face, this stuff is great. It literally is so serum like sinks into your skin within five minutes or sooner. Now it’s not the most hydrating thing in the world so if you have a dry skin, you still wanna go in with a moisturizer before however, if you have oily skin, this is your girl right here. Skin like finish, not super matte and not dewy at all. I do not wear primer so I don’t know how it plays with that. Works great under my makeup and has never caused pilling. Quick, easy, simple ingredients, definitely sensitive skin friendly, and no fragrance at an affordable cost-effective price! Now if only banana boat decided to go cruelty free😭 9/10 bc not CF 💔
