Purchased the 12000 BTU model. It says it can very well cover spaces up to 500 feet squared, I have it in a 288 squared foot room and it struggles to cool at the lowest temperature (62F). Can’t imagine how it’s going to be when the heat wave comes. It says it’s returnable up to a reasonable time frame, and even if it goes past that there’s only a slight restocking fee, but after paying an electrician for to run a new line and install a disconnect box and making a hole in my wall, it’s not worth removing and returning it. At this point something is better than nothing so I’m just keeping it but I’m disappointed. Either purchase a model higher than what you need or research into other models.

Bulletproof packaging, which was great and appreciated; all components protected very well. Very easy to install, and important to note that this appears to be the only MrCool model on 115-volts. I had a simple question that I sent through the MrCool website and customer service answered in under 24 hours. My recommendation to other DIY installers is to watch the videos AND read the instruction manual fully before installing. There are little things (like checking the routing and seal on the drain) that you can't do once the inside unit is up on the wall. There's also scant info on properly connecting the electrical, so I'll just say to check your local code and probably buy a fuse-less switch to mount within sight of the outside unit and use a dedicated circuit for the installation. All that said, this was super easy to install and works like a dream for my COVID19-created home office in a formerly unconditioned garage space. Keeps the only partially insulated 350 square feet comfortable and cool. Highly recommend this product!

I have had Mr. Cool a month now. Have not had any problems, would recommend also purchasing Mr.cool mini stat. The DIY unit is the easiest no need to vacuum lines , U may need an electrician to run your power to the unit if You are not comfortable working with electrical wires or do not already have a disconnect box outside near the unit.

great until 3 weeks later
Unit works great and is super quiet, easy install. However 3 weeks later the vent door does not close all the way when unit is powered off. It sits there looking at me like a imbecile with its mouth hanging open. It makes me feel like a imbecile for buying the most expensive unit expecting reliability. I can not take it off the wall to return it without losing the refrigerant gas. Do not be a imbecile like me and consider other brands.

One of my best purchases!
Purchased this on sale which made this one of the most amazing values I've ever purchased. After living with window A/C for years, we finally bit the bullet and tried our luck with this DIY split system based on the great reviews and apparent ease of installation. Not disappointed! Installation took about 4 hours totally on my own, including some light electrical. Expect more if running completely new electrical to unit. If you can turn a wrench and run a cordless drill, you can handle this project. DIY difficulty? 4/10 for an experienced DIY'r in my opinion. Instructions were fairly clear to understand for me. There are also some decent Youtube videos if you find yourself scratching your head. As far as quality is concerned, I couldn't find any flaws. All of the joints and welds looked professional and clean. The inside unit is modern looking and unobtrusive. Remote is easy to navigate. Outside unit has a small footprint and is less of an eyesore than most central air units. QUIET!!! I was literally wondering if I had done something wrong during installation or had a faulty unit after starting for the first time. I could not hear the inside or outside units running until I got within a few feet of them. Even on "Turbo" the inside unit was easily drowned out by my TV at low volume. Could not be happier with the noise. Now, for my only complaint. The line set (outside piping) wrap provided is lacking. I've seen a few reviews where they run out before completing the entire lines. I did have this issue also. I needed around 3 feet more to complete. I can live with it, and get some more locally, but wold be nice to have and extra roll. One suggestion to MRCOOL. The vertical auto louver feature is a nice touch, but what would have really been GREAT? Horizontal auto sweep to cover an entire area. That would make these Gen 3 units the best units available!
