  • Cools very well
Installed this about a week ago and it cools the bathroom and bedroom so well I had to pull up the blanket when I sleep. Can't speak to reliability as haven't owned it for only little over one month. The installation instructions are detailed to a point, however watching several videos helped somewhat. You will need a 120V outside disconnect (non-fusible type), pad for the condenser to sit on (concrete or plastic), 20A Single Pole Circuit Breaker. Concrete Anchors or Screws to secure the outside unit to the pad and non expanding foam to fill up the 3.5" hole for the line set, drain hose and control cable to go through the wall. Installing the inside unit on the wall requires two people. It also came with the line set cover to hide everything on the outside wall. I did have to call them and request additional rolls of UV resistant tape for the line set which they sent right away. Overall very pleased and looking into a larger Mr Cool system for the entire house. ... show more

  • Great Mini-Split HVAC for DIY
Very easy to install. Instructions were complete and written for novice. Not as heavy as I thought it would be. Both the indoor unit and the outdoor unit are VERY quiet. I setup mine on WIFI and can control remotely. My only downside (which is not a complaint) is that because it is DIY, it comes with pre-charged fixed tubing length (16ft or 24ft?) with the connectors permanently installed on each end, so if your space between the units is less, you end up with a coil of tubing. I don't know any way around it, and it does NOT effect the operation or efficiency. Just something to consider. I ended up building a small box on the outside wall surrounding the extra coil near the outdoor unit. Their engineers have done a great job designing a system that is truly DIY - maybe they can figure out a way to customize the tubing length? Would highly recommend, and would definitely buy again. ... show more

  • Easy for DIYers as described.
Had a single car garage (220sq ft) and needed to cool and heat it when the time comes. Bought a little $300 portable AC unit with one exhaust outlet but that didn’t do the job well in the summer and didn’t heat in the winter (Los Angeles weather). So saw this DIY unit and since I’m a DIY guy all the way thru and thru, decided to take a stab at it. I’ve seen similar units run at my work places being used in our server rooms so I know these units work. Install took about 4 hours with 2 guys taking our time. Hardest part was running the plastics line covers (lol) to protect the line sets. Everything else was easy (just watch the YouTube video and you’ll be set). Wired up the electrical and plugged one end to my normal 110 outlet on the side of my house and was good to go! Noise is super quiet for the compressor fan that I have to go outside to check that it’s actually running. This was one of my worries since the unit is close to my neighbor’s house and next to my sons bedroom window. I thought it’ll be semi loud like my normal whole house AC COMPRESSOR, but it’s super quiet (sounds like a small fan set on medium). All in all, I use the ‘comfort’ setting and its majntained 75 degrees constant. Will have to see how it’ll do in the so cal summer but I fingered it’ll cool fine for a small space. Very happy with the purchase and value of the unit. ... show more

  • Delightful unit
Pretty easy to install. Directions and online videos aid if you're not super comfortable doing it on your own. I use the unit in a 10' x 14' shop in my garage ... working great so far!

  • Amazing customer service
Very rarely do I write a review, but never have encountered such amazing customer service at Ingrams water and Air LLC. The 12k mini- split works great , I just bought a second 12k unit , unfortunately the line set was damaged , there was kink in the line, which I didn’t notice till after it was installed . I though this was going to be a nightmare getting a replacement . ! But Reuben In the warranty department and and John at tech department who both work at Ingrams water and Air LLC. where amazing. Asked for a picture of the kink, and a day later received tracking info on the new unit and linset. One email and one phone call !! Most professional and courteous people I have ever dealt with. Usually it takes me a day to get anybody at my own bank . They made what would seem like a pain into into a painless process . Thank you Ruben and John . ... show more

  • Superb Product
I wanted to install Ductless Mini Split on my Side Apartment, which was initially estimated at $4500 by a professional. I decided to install MrCool 12000BTU unit myself and it was extremely easy to install. It took me few hours to install and the documentation helped me a lot. On another note, outdoor unit doesnt make any noise, i literally go to the unit and see, if its switched on. Highly recommend the product. ... show more

  • Great option fir DIYers
This thing is amazing! We installed it upstairs in our daughter’s room where it gets pretty hot during Texas summers (and every other season, if I’m being honest). It took a little more time than it normally would because it was on the second story, and we had to remove the central ac ductwork. But… Hers is now the coldest room in the house! It is so quiet, I never hear it running. We are planning to get another one for our bedroom. Get this. It’s great! ... show more

  • Works great but missing parts!
We had our mini split installed over the weekend. All is working fine (and it connects to Google) but the line cover set was missing. As the Line Cover Set is $170 on Amazon, I contacted the seller to get this resolved. I'll have to pay the installers again to install the line cover set which wouldn't have happened if all the included items were in the box. ... show more
