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. Get the best for your home and install a DIY®!

Flimsy and doesn’t hold weight
Size: 17 Inch, Color: Natural, Size: 17 Inch, Color: Natural
Do not buy this. The frame this comes with is so small and flimsy. I didn’t even have anything on the shelves yet and they were falling off the wall. The wood is a beautiful color but the quality is awful. I had different floating shelves on the same wall and I included a picture of the thick metal frame those came with, also from Amazon to show how flimsy this brand is.

Really nice shelves well-made
Size: 30 Inch, Color: Walnut, Size: 30 Inch, Color: Walnut
I recently installed a set of floating wooden shelves above my kitchen sink, and they have completely transformed the space. The natural wood grain adds warmth and character, making my kitchen feel more open and inviting. The shelves are sturdy and well-made, supporting everything from dishware to small plants and decorative items without any sagging. Installation was straightforward, with the included hardware making it easy to mount them securely. I was pleasantly surprised by how well they hold weight while maintaining a sleek, minimalistic look. The floating design gives a clean, uncluttered aesthetic, which is exactly what I was looking for. Functionally, they’ve made a huge difference. I can now keep everyday essentials like mugs and spices within easy reach while freeing up valuable counter space. They’re also a great alternative to upper cabinets, preventing the area above my sink from feeling closed in. Overall, these floating wooden shelves are both practical and stylish. Whether you’re looking to add storage or just enhance your kitchen’s design, they’re a fantastic option. I highly recommend them for anyone wanting a simple yet impactful upgrade to their space!

Look nice, not sturdy or supportive
Size: 17 Inch, Color: Dark Blue
The color and thickness of the shelf is great. Very easy to install. But the wall mount portion is cheaply made and doesn’t support the shelf as well as it should. Once mounted the shelf leans forward and isn’t sturdy. After mounting, I found my items had slid off end up on the floor.

These are beautiful! I bought them for my Grandsons Baseball room. We haven’t put them up yet. They will be a great addition to his red, white, and blue baseball room!

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️
