Powerful DIY Comfort for Medium-Sized Spaces

The MRCOOL DIY® Select 12,000 BTU Single Zone Mini Split Heat Pump delivers reliable year-round heating and cooling for spaces up to 550 square feet without the cost of professional installation. Designed for true DIY installation, this 115V mini split system includes an 11.5 ft pre-charged Quick Connect® line set, allowing homeowners to install their own HVAC system without vacuum pumps, gauges, or refrigerant handling.

Built on proven MRCOOL® technology, the DIY Select series offers a budget-friendly alternative to traditional ductless systems while still delivering the features that matter: inverter-driven efficiency, quiet operation, smart control, and simplified installation.

What Makes the DIY Select 12K Different?

Many low-cost mini split systems still require proper evacuation, specialized tools, and refrigerant handling. When those steps are skipped, performance and longevity can suffer. The MRCOOL DIY Select 12K eliminates that risk with factory pre-charged Quick Connect® fittings, allowing homeowners to install the system without opening the refrigerant circuit.

The result is a simpler, cleaner, and more reliable installation process that removes one of the biggest barriers to owning a ductless mini split system.

Includes 11.5 ft Pre-Charged Line Set

The included 11.5 ft pre-charged line set is a major advantage over standard DIY systems that often include longer 16 ft or 25 ft line sets. This shorter length helps reduce excess coiling, resulting in a cleaner and more professional installation.

For installations requiring longer runs, optional pre-charged line sets are available in 16 ft, 25 ft, 35 ft, and 50 ft lengths.

Designed for True DIY Installation

The MRCOOL DIY Select 12K removes the most complicated part of mini split installation. The pre-charged Quick Connect® line set eliminates the need for vacuum pumps, gauges, and refrigerant handling, allowing homeowners to install the system with basic tools.

This significantly reduces installation cost while maintaining reliable system performance, making it an ideal solution for homeowners who want professional-level comfort without the professional install bill.

White Standard, Black Option Coming Soon

The system includes a standard white indoor air handler designed to blend into most residential spaces. MRCOOL has also introduced a black air handler option for the DIY Select series, ideal for modern interiors, garages, and design-focused environments.

The black SKU has not yet been released but will be available as a selectable option once launched.

Smart Control and Connected Comfort

Control your system from anywhere using the MRCOOL® Comfort App. Adjust temperature, set schedules, and monitor performance directly from your smartphone. Voice control compatibility with Amazon Alexa and Google Assistant adds even more convenience.

Not a bad start
Format: Kindle
3 stars Thank you Netgalley and Briar Boleyn for the ARC! A camelot/king Arthur retelling with fae. I was hooked by the idea of this book immediately and was eager to jump into this world. • slow burn • enemies to lovers • who did this to you Morgan Pendragon watched her mother die by her father's hand when she was just eight years old, hiding under the bed. Morgan is believed to have the tainted blood of the fae in her veins and is cast aside so that her fathers illegitimate son, Arthur, can become the king. She's seen his cruel treatment of the fae firsthand, so when he sends her on a journey to find a fae weapon she seizes the opportunity to do more with her life. Along the way, she finds more than she could have imagined. I don't know a whole lot about King Arthur and Camelot but I had a lot of fun with this story! The plot has some similar tropes to popular romantasy books (From blood and ash) but there's enough originality here that it doesn't feel like I'm reading a copy. I liked how the fae were different in appearance than what is typical in most fantasy books I've read. In this book they have blue hair, violet skin and a wide range of other characteristics. I thought that the world building was easy to follow and I could easily immerse myself into this world. After reading the blurb I kept wondering when she was going to go on the journey to find Excalibur and it doesn't happen until around the 45% mark. The story is a bit slow at times but starts to pick up once they begin their journey to find Excalibur. The John Wick style Inn was a fun concept that I enjoyed reading about. There are a lot of similarities to this and FBAA and I would have liked to have it be a little more different, but I'm hoping book two will have the story turn into something of its own. Overall I enjoyed reading this story and I'm looking forward to reading book two especially after that ending.

I LOVE this book so much!!!!!
Format: Kindle
WOW what a ride!!! To Bleed A Kingdom is Ella Dawes debut book and I am thoroughly impressed by her writing! She writes like a seasoned author already! I absolutely LOVE her writing style it’s fun easy to follow and very imaginative and expressive where a reader can actually FEEL what the characters are going through or have gone through. This world and the characters in it are so very relatable so real feeling like they could actually be my family and friends and enemies also lol The mystery surrounding Lena her friends or found family and their lives is not reveled wholly in this book we get pieces and I really loved that, normally I’m very impatient but with the way this world and all the characters are written it doesn’t become so much the main focus. We get a really solid feel for this world and all it’s going on and people in it. New friendships and love interests are formed it’s a very character driven story which I personally love!! Lena is beautifully broken and flawed but sooooo incredibly strong without the unnecessary stubbornness we come across in so many books and what a breath of fresh air that was to read! Darius is an Alpha male through and through with a LOT of emotional trauma but he loves and he loves hard even when he doesn’t really realize it himself. The side characters are phenomenal the dialogue is sooo good the banter is hilarious and the loyalty and love between them all is written beautifully! The spice is little but it’s amazing when it happens wink wink I don’t like cliffhangers especially when I’m not sure when the next book will be released I’ve been burned too many times but once I got started reading this I didn’t stop all day and late into the night so I’m going to have find my patience and wait and I am so very excited to see where Ella takes this story. Thank you for sharing this story with us can’t wait for more!!! I read this on KU

A Dark Fantasy that hooks you from the start!
Format: Kindle
⭐️⭐️⭐️⭐️ 🌶️🌶️ Right from the prologue, I was hooked. Ella wastes no time diving into an intense scene, but definitely be sure to read the trigger warnings! I was immediately drawn into this dark fantasy world, and even more so by the slow-burn tension, witty banter, and the strong sense of family that forms throughout the story. What I really loved is that Darius, the Queen’s illegitimate son and captain of the guard, is the main focus of the book. Broken and struggling to navigate the prejudices against him, Darius is caught between playing the political games and wanting to be accepted. He’s also investigating a growing threat: demons, who have always been a manageable evil, are suddenly multiplying and attacking in larger groups. His focus shifts when Lena, a mysterious foreigner with an aura that can’t be ignored, arrives on the scene. She’s not quite human—something other—and I found myself just as captivated as Darius, trying to uncover who she is and what role she has in his life. The tension and spice had me reading into the late hours of the night - romantasy readers are going to devour this book! This book also does an excellent job of challenging stereotypes, labels, and unconscious bias. I love how Ella seamlessly weaves these complex themes into the plot, and how the characters navigate them in ways that feel authentic and thought-provoking. 🎧 ⭐️⭐️⭐️⭐️ Another highlight was the narration by Laura Horowitz! She does an amazing job bringing the characters to life with different accents and voices, capturing Amara’s sassiness and Lena’s mysterious nature perfectly. It took me a little while to adjust to Darius' narration, though—it wasn’t quite what I had imagined for him or other male characters. But once I sped it up to 2.0, it felt much better. As for Kace and Griffin, I still struggled a bit with their voices, especially Kace, whose tone came off more like a silly jester than the commanding yet light-hearted character I envisioned.

My current fave! Total must-read!
Format: Kindle
To Bleed a Kingdom" is an absolute rollercoaster of a read that I couldn't put down! From the get-go, Dawes throws you into the thick of it with a horrific scene that sets the stage of Seboia. It will leave you in shock. Major trigger there, but honestly, I will say it was done so tastefully I really appreciated having it on the offset! Then we meet the brooding, forgotten Captain Darius. He’s a mountain of a man, terrifying, but has an absolute heart of gold. He’s fighting to protect his Kingdom in the midst of immense chaos from the terrifying Soulless. And then there's Lena, a fierce and intelligent leader who swoops in and turns Darius's world upside down. Their attraction to one another is seriously unwanted, particularly with all that’s going down. But it’s absolutely intoxicating and I can not get enough of it! But it's not just about the romance – oh no! Dawes is a master story teller, weaving in elements of suspense, mystery, a world of gods and fiendish supernatural creatures, and that much needed banter in a story like this. Lena and her gang of misfits are a riot, reminding me of the antics I used to get up to with my own sister. And let's talk about Darius's backstory – it's totally gut-wrenching, and so you’re instantly in love. I mean, who doesn't love a brooding, tortured hero? But the real star of the show here is the world-building. Dawes has created a rich and intricate universe filled with gods, fae, and supernatural creatures that all weaves in perfectly. The way she integrates gems and their significance is genius, adding a whole new layer to the story. If you're a fan of epic dark fantasy with a paranormal twist, this is the book for you. And don't even get me started on that cliffhanger – I'm already counting down the days until book two hits the shelves! Definite must-read.

Why can't they just TALK to each other?!
Format: Kindle
The prologue to this book was bloody and violent. I actually started this book then put it away for several months as I found it not enjoyable. When I finally returned to the book, I pretty much skipped the prologue and went right in. There are a lot of holes in this story, a lot of repetitive sections, and several parts (mostly the whole book) where you just want the lead characters to talk to each other instead of being petty and jealous. Who the female lead is, is never really explained. The humans are considered weak, but the human kingdom is the one they fear, just really weird. I did finish the book and it was overall a good book, and I may actually read the second book to see if any questions are answered and holes in the story filled in. Don't take that as an endorsement, if it was a really good book I would be reluctant to read more as I wouldn't want the story ruined, but just being so-so, there is nothing to ruin and maybe the next will be better. If you're on the fence stay there until you run out of better options, then give it a go.
