This is my second Mr. Cool mini split that I've installed in our home. The unit is easy to install, I did hire an electrician to wire up a dedicated 30 amp circuit, but aside from that I did the rest of the install myself. You will need to purchase a hole saw for your drill to be able to drill the right hole through the wall. Sadly, I almost nicked the electrical wiring in my wall, BE VERY CAREFUL when using the hole saw that you're not drilling through plumbing or electrical wiring. Also, you will need to purchase a pad to set the unit on outside. I recommend a foam one, they are much easier to deal with than having to pour concrete, and fairly easy to get level. I didn't get it 100% perfectly level, but it's within tolerances and it looks great on the pad outside. The wires and the AC hoses are way too long, and that's my only complaint, the install doesn't look 100% professional because you can't cut the AC lines or they will loose all the refrigerant and you would have to recharge them again. Anyway, they are coiled up next to the unit. It's on the side of the house so no one can really see it. The remote is easy to use and has a lot of great functions including "follow me" which you can then set the remote next to your bed and it will maintain the temperature at the remote, instead of maintaining the temp at the unit. There is also a dehumidify function, but honestly I don't know how different it is then cooling. There is no way to properly dehumidify the room unless you cool it as well, so often times when I want to dehumidify I have to freeze myself out of the room as well. The heat works great in the winter, perfect for San Diego, not sure how perfect it would be in sub zero climates since it does take a while to come on in those climates. One thing I recommend is buying a line set cover to cover up the line sets outside. Unfortunately, most of them are barely big enough to fit the drain line, power and compressor lines, but you can squeeze them all in and get it to fit. The line set cover gives it a nice finished look. You can get a generic one on Amazon and save money versus buying the Mr. Cool one. One cool thing, we have solar on our roof (4.6kW) and running the Mr. Cool's in all 3 bedrooms of our home on a hot day our solar was still giving back 1KW to the power company. This is so much more efficient than a central AC system.

Well, so far….so wonderful! We watched videos and read the instruction, first of all. Hubby then laid out all the parts and they were all intact, well packed too. He then poured a concrete pad for the outside compressor and allowed it to dry and cure. Once he knew everything was ready, he took his time, a few hours, and installed the unit. WOW, AMAZING! Both inside and outside units are whisper quiet; can’t really hear the inside unit on the other side of the room. When I returned home from work, we installed the USB unit so we could control the system remotely from the app and from Alexa….this is great! Please be sure you take your time and follow instructions. Watch some YouTube videos, good ones, because there are definitely some lousy ones that will get you into trouble during install. All said and done? The install was easy and this unit will save you so much money because you don’t need to hire a pro. Cooling and Heating is so comfortable, without blowing hard or loudly into the room. The fan mode works well, as well. Right now I canno say enough about this system….wish we would’ve purchased this years ago. Good luck and I hope you enjoy your Mr. Cool as much as we do. Will add indoor pics soon. UPDATE: We’ve been using this unit daily and are absolutely impressed! We live in the desert so this time of year morning temps are in the 40s and daytime in the 80s, therefore we use AC and heat in the same day and this Mr. Cool is impressive, to say the least. I’m so hoping it is quality and holds up because we’re so happy with this purchase.

Bought a 9k for the garage, 400 ish sq ft, mainly for the heat. Works great even in single digits. Doesn't use that much power and was super easy to install. Cools really well too. Mounted it on the wall to keep it out of the snow and dirt. Only drawback is it vibrates the wall during certain cycles.

I am handy, but never installed a heat pump before. I am pleased to say the MrCool DIY product installation was a success. Spending the extra $$ for the efficiency seems worthwhile, and both the interior and exterior unit are surprisingly quiet. The Internet device was also easy to install and use (but I wish it had Apple Home support). This product still gets top stars for my review, but here are some tips to be helpful to others: - The cardboard template was a bit off, specifically regarding the cutout hole. This left the unit tipsy, so it leaked on the left side; the solution was to rehang the interior unit based on the outgoing pipes that forced the unit up. - I purchased an HVAC torque wrench ($95), but in hindsight I could have probably estimated the tightening. - I was worried about bending the cables, but it turned out OK as long as I was careful. - The exterior duct cover came with 90° bends, but frankly this is wrong since the drainage line should always have some declination. My solution was to add an angle in the horizontal exterior run. The attached picture shows the unit mostly installed before adding vinyl wrapping to the coiled items. I am planning on screwing the unit to the stone supports, but need a mortar drill bit. Overall, my out-of-pocket costs (<$2K) are significantly less than the professional estimates ($5K-$6K). THANK YOU to MrCool for offering a handyman-friendly solution.
