Rated 5 out of 5 by from Easy install Just installed, all seems good. Very good directions
Date published: 2019-11-13
Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Easy install we've had regular window units and we made the switch to Mr. Cool and it has already done spectacular in the IL humidity for us and cooled down the house so quickly. took a couple of people to do the install but we did it as a family ourselves and we are very excited about it.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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..

Rated 5 out of 5 by from Great option for DIY'er This is my second unit, they have both functioned as expected. The price is great and considering the savings from being able to install it yourself you can't beat it.

Rated 5 out of 5 by from Seriously Saved Me Last year I spent about $2,000 during the winter to warm the house with propane. This year I got a Mr. Cool and my heating costs have been cut in half. Additionally, it was easy to install and it works constantly without a sound. I was sure my electric bill was going to go through the roof, but the increase is negligible. Absolutely the best thing I have purchased for my home since I got it.

Rated 5 out of 5 by from Great unit We purchase this unit with two air handlers and was impress on how quick and easy our Technician completed the install. The unit is very functional and works great during the winter months in two rooms.We just set the temperature and forget it. We plan to convert more rooms at a later date.

Rated 5 out of 5 by from Surprisingly easy to install. I'm 73 years old. I bought this to heat and cool my 24' x 36' x 14' ceiling workshop. I read the detailed instructions and watched a couple YouTube videos. I had never worked with HVAC prior to wiring and installing this unit, It was easy to understand the unit and its installation. I installed it by myself (there were a couple steps that I could have used a little help). So far, so good. I've been through a -12 F night with no issues. Love it.

Rated 5 out of 5 by from Works great! Bought this DIY unit last June and installed it in time to save our bacon during a very hot summer.
Date published: 2019-01-23
Rated 5 out of 5 by from Experience of Mechanically Competent Home Owner I bought the unit about six months and ago. It worked very well at air conditioning a fairly large master bedroom suite and it is extremely quiet. I tried using it for heating and failed to properly place it on the hear mode. Once corrected, it worked equally well for heating. This is an excellent functional unit, but the installation was more of a challenge than the online videos represent, so anticipate that it will take more time and effort than your optimum expectations. It is doable and you will need a second person to help you with the mounting on the wall. I am overall very pleased with the unit.
Date published: 2019-01-23
Rated 5 out of 5 by from 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>
Date published: 2019-01-23
Rated 5 out of 5 by from Works great, easy installation I've had this in my garage for two seasons now. It keeps it nice and cool in the summer and so far this winter, it's keeping it warm. Installed it myself in a few hours and it works great even in the dusty garage. I highly recommend it!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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'.
