Terrific air conditioner
A well thought out design. The air handler that you mount on your wall has the return vent right on the top of it which makes it super efficient. It pulls the hot air from the ceiling and pushes cold air out underneath of it. I use it to cool down a 432 square foot living area and from the start up to comfortable cool takes five minutes. I can honestly say it's the best air conditioner I ever installed for myself. I'm 72 years old and I installed it myself, with the only help, was getting the line set through the wall.

Great Product
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.

Great DIY Product! Quiet and Easy to Install.
Bought this to cool and dehumidify my garage. Great packaging...well protected and easy to unpack once it arrived. Just follow the instructions and you will be on your way to a comfortable space. Received the newest Enhance Smart Controller which provides the WiFi link to the air conditioner through the SmartHVAC app on my iPhone. The App is great and has worked flawlessly since I installed the mini-split. I like all the features except the history. I feel the ON duration should track the compressor run time, not the system On time. I find the system on time rather worthless in tracking how efficiently my schedules are working.

This thing rocks
I have had this installed for about 6 months over the winter in New England. I am very satisfied with its ability to Heat with low outside temps down to 5 degree F. It is heating a 18x20 2 story shop 65 degrees without issues. Love it..

Great Product!
Easy to install as a DIY kit. Works very well as both cooling and heating in a 400 sq. ft."she-shed". Only complaint is I wish there were options to order units with shorter line sets. Other than the 25 foot line set, all else is a big plus>

Love My Mr Cool!
I replaced an old electric furnace in my garage with the 18k unit. The DIY model was as advertised...very easy to install. I finished on a 95* day in July, shut the garage and fired up the unit. Within 2 hours the humidity was gone and the temp was 76*. Unless you have an electrical background like me, you only have to hire an electrician. I now have heat and AC in my 3-car garage running off only 20 amps....compared to the 90amps of the old beast.

Reliable, quiet, economical
Installed a DIY 24K MrCool fall of 2017, flawless operation both heating and cooling modes ever since. Installed a DIY 18K MrCool at my other place four months ago and is working as well as the other one. Haven't used it in cooling mode yet. In both installations the indoor unit was a struggle to hang onto its mounting bracket. It has to slid down onto the metal tangs and I and my helper just had to keep trying until it seemed right. Otherwise not too hard to install.

Love it!!
I got this over a year ago and we love it! The only thing we were not crazy about is that we were not able to get the app to work with the unit, but as far as the unit goes, it is amazing. We are very very happy with it!

Bypass the expensive installation costs.
After reading other online reviews, and researching the installation process, I purchased a MRCOOL 18 K Mini-split system for my remodeled attic. The installation instructions were through and it took us about 4 hours to complete. The unit now quietly cools and heats the attic comfortably! Saved me lots of money installing it ourselves. No real need for a costly HVAC 'expert'.

Great for Workshop
This has been a great addition to my garage workshop! I installed it myself which went as advertised and no problems. It worked great for cooling in the Las Vegas summer heat. It has been heating the garage in the colder weather as well. I should say that the garage is insulated and is about 650 sq ft. I have not noted any major change to my electric bill but i only run it when i am working in the area.

Very Efficient
I bought this in the summer, mostly to cool my sunroom on really muggy days, but also for backup heat to compliment my ventless gas stove. Turns out MrCool is more efficient than the stove, so I am using it most of the time.

I bought this unit after much research and am very happy with the performance. I am very handy and although it is a DIY unit it really is at least a two person job. Also if you are not comfortable with electrical should get someone to assist with electrical connections.

Easy to Use!
We bought this unit last spring and it was a lifesaver last summer. I was unsure of how good a mini split unit would perform in our home and therefore put off buying one for a few years. We were at a friends house who had just purchased one and we were quite surprised at how easily it cooled their large living/dining area, how easy it was to install and how affordable it was. We have an above ground raised ranch and wanted the unit for our living space on second level which is usually very hot in summer. We placed the unit in our living/dining room directly across from hallway leading to 3BRs & Bath. This unit is so strong It cools our house almost all the way to end bedrooms, despite the fact that the stairway leading downstairs to our foyer is only 15’ away from where the unit is blowing. We do still require another ac unit in the bedrooms but we are so happy that this unit actually cools almost the whole upstairs area. In the past we couldn’t even cook or enjoy eating upstairs because it was just to hot. Now we actually need sweaters while sitting in living room. We are thinking of getting another smaller unit for the bedroom. My husband and son did the installation without any problems. Greatest investment we ever made!! Don’t hesitate if you’re thinking of buying one they are worth every penny.

Installed this in a large and poorly insulated Florida sun room and it works great. Cools fast and does great at controlling humidity. Heating is just as good. I installed this myself but I definitely recommend having an electrician handle the electrical work. Very happy with purchase!

Just what I needed for my garage/workshop
It's been great to go out to the shop and have a comfortable working area. Not having to use a propane heater indoors, is great. I just set the thermostat at 64, and it keeps the temperature comfortable.

Simple and works great
Have no complaints at all works great I have it in a 600 sq ft building and heats and cools great FYI I live in Tx so like my home state of man I would do more research on heating with it. In the summer I mostly keep it on the dry setting witch is dehumidify and it works great. Simple installation I did it by myself.

Absolutely love this machine!!!
Really, if you have any interest in installing this yourself... You should. The Company seems solid and the unit is flawless. I can't say enough about this unit and how well it works. This particular unit cools a ~500 sq ft space above our garage. It gets blistering hot up there and this unit just kills the heat. Do it!

I love this unit, however, if you are installing it yourself, watch as many videos as you can because the instruction book doesn't help much, but neither does the mccool videos. Take your time and make sure you are sure of what to do.
