I bought several months ago and I still have problems with the mount bending and moving. I will have to take the whole unit down and glue and screw the mount to a more substantial backing (plywood likely) - cut out the drywall and remount the unit. The WiFi control does not work - and I have tried different routers. It never connects. I will likely order another brand next time I need a split unit. Also - they could not deliver to my house. I had to reschedule delivery a few times and then meet them at a different location and load the unit in my car to take to the house.

When I bought this unit everyone said it wouldn't last a month. It almost made it a month before the blower motor for the inside unit went out. They sent me another motor right away. No instructions for replacing the old one, however. Needless to say, it's a difficult chore if you are not an ac service tech. If I hadn't found a video on YouTube , I probably could not have repaired it. Very slow response from the company that sold it to me. It was an Amazon purchase filled by someone else. It has worked fine since the repair. But I have no confidence in the unit after it failing in the first month. I wouldn't buy it again.

Purchased the unit last summer. My brother and I did the installation - it does require four hands. Followed the instructions and just like that, the unit was installed, lines charged and cables energized - the cooling unit works great, the heat too! I've had many of my friends ask about it and one just bought one for an extra room. Great product.

This unit is great in the summer and cools off very well, however in the winter time i have this in a 400 sq ft shop with only 9 ft ceilings well insulated and it takes several hours to take the chill out and my electric bill is is insane. i bought this unit only to take the chill out and did not think it would take the place of a larger gas unit but very disappointed in the heating aspect.

I purchased the Mr Cool 24,000 BTU for my 3 car garage in the desert of Arizona and it runs cooler then my new AC in my house! This unit heats fast and cools fast. My garage temperature runs about 80 degrees in the summer heat of 105-110 degrees. I have not insulated my walls and ceiling yet and I am amazed with this units cooling. The installation was very easy and the best part was the small opening I had to put in the wall. I highly recommend the Mr Cool system.

Very happy with unit but install went very hard made for 2x6 construction not 2x4 if they had flex go into wall and connect inside would have made install a lot easier . Kinked piped trying to bend and had to have friend cut and reconnect pipe . Need thre people to help install 24 k unit

I have a 1,000 SqFt garage with high ceilings and thought this would do a better job heating and cooling. It does work but doesn't do enough. I am still working on insulating the whole garage in hopes that once its finished this unit does a better job.

After a lot of careful research, I decided there was no real magic in being able to install a ductless unit to keep my garage cool in the summer. My Mr. Cool unit was just the thing I needed. Now the video makes the install look like it takes 20 minutes, and I am here to tell you this realistically does take a little planning, and a little time to install, but if you do your homework, the install is more physical than technical. The hardest part is making sure you are boring the hole in the right place cause let's face it, no one wants a 3 inch hole in their wall. Once you get it all laid out and planed and measured, cut the hole and install the unit. It really is that simple. I started my install around 11am and by 5pm I was as cool as a cucumber. The pre-charged lines are a breeze, and if you plan where you are going to install the outside unit, you can usually place it where you can make use of the extra line instead of coiling it up, but either way works fine. Don't kink the lines and you are good to go. This install saved me a bunch, and I recommend the unit to all of my friends. In a hot shop or garage, I recommend over-rating the unit just a bit. I did and it works perfectly for my space. Great home addition.

(This is not a review for the Oasis hyper 230 volt listed above) I bought the Mr Cool DIY 12,000 BTU 500 sqft ductless mini split air conditioner with heater 115 Volt 20 amp Model DIY-12-HP-115A. I bought this last year to put in our master bedroom for my wife, she has a medical condition so during the summer time we keep the master bedroom between 64° to 66° and during the winter about 77° it has been very practical and was easy to install with the help of my son. I've had no issues with it yet, works great for cooling and heating the master bedroom only. It was the best buy for our needs would recommend whether for one room, or great for shop about 500 sqft. It gets cold enough for me to use an extra blanket during the summer time.

I selected this unit because the warranty is valid for DIY - unlike most competition. Installation was straight forward. If you can tighten a bolt, then you can connect the condenser to the air handler - that simple. Packaging was VERY well done - no chance of shipping damage. Installed just in time to weather a week long heat wave. Unit worked flawlessly. Very happy.
