- Variable-speed DC inverter compressor technology increases energy efficiency compared to other mini-split air conditioning units. SLEEP mode on remote:Sleep mode will automatically adjust the temperature to maximize comfort during night time sleep. When in COOL mode, the unit will increase the temperature by 2°F after 1 hour, and will increase an additional 2°F after another hour. When in HEAT mode, the unit will decrease the temperature by 2°F after 1 hour, and will decrease an additional 2°F after another hour.After 7 hours operating in SLEEP mode, the system will switch off automatically.
- Low ambient cooling: cooling down to 5°F - this feature makes the Mrcool DIY the ideal system for computer server rooms, greenhouses, and any other application that requires cooling all year. Follow me feature: by pressing the 'follow me' button and keeping the remote close to you, you tell the air conditioner to set the temperature from wherever the remote happens to be, this counteracts the tendency for the air conditioner to stop cooling or heating because the air around the unit has reached its set temperature
- LEAKAGE DETECTION: Protecting Your Investment - When the MRCOOL DIY detects low coolant an alarm will sound to alert you to the problem. This will prevent damage to the compressor while you maintain high air comfort.

    I am loving my Mr. Cool
  

*by B***S on Reviewed in the United States on February 16, 2020*

We had a sunroom that was not heated in our new house in Maine and I needed something to heat during the winter and cool in the summer.  I got to looking at these on Amazon and youtube and decided to try one.  The room is a 14 x 20 room with windows on both sides.  This 12K unit does outstanding in the summer for A/C and it does good in the winter.  During the cold cold weather (below 10 degrees F) it runs constantly, but it does keep the room warm.  We have had a couple of below zero nights and I put a space heater in the room just to give it some support.  It is not nearly as efficient heating as it is cooling, but I am overall very happy.  The install was some serious work as you have to be careful of the copper lines as you feed them through.  I wanted to hide all my lines so I ran them through closets and spaces to the basement before I went outside with it.  The 25' of charged lines was just enough for my application.  I also had to run a new 110 circuit off my breaker panel which took me longer.  Overall I spent a full day, but the install came out really nice!  I have the compressor hung on brackets outside the house and it looks good.  Overall I am very happy with my purchase and I may look to do another somewhere else in the house (mainly for A/C in the summer).  If you are going to have to pay an electrician to come out and/or you are not comfortable doing a project like this; I would probably go with a different brand/model where you can get it installed and get support.  I only did this unit as a strong DIY person, I did all of it with a little help from my wife.  I think I did the whole project for about $1500.

    Know wiring, and don't bend the copper lines. Have at least one person to help guide the lines!!

    Pretty simple to install. Working well so far
  

*by A***L on Reviewed in the United States on June 30, 2019*

Just got through installing this unit. I was replacing a Pioneer unit which was absolute junk. The unit is extremely well packaged, the shipping company would have to drive over it to damage it , so you should have no issues receiving a damaged unit. As mentioned by some other reviewers, you really will need another person to help when it comes to running the lines out the hole because they are attached to the inside unit. The lines are very flexible so you would really have to be super-careless to damage them during the installation. Power connection is a breeze even for someone who isn't experienced. I didn't use the condensation hose that came with it, instead I inserted the short attached condensation line to a piece of pvc pipe when I ran down the wall. Hooked up the lines, opened the valves and used a spray bottle with some Dawn detergent to check for leaks. Powered the unit up, turned it on and checked for leaks again. Unit is working great and the outside compressor is super quiet. I'll probably end up replacing the Pioneer unit I have at the store with one of these.
