I bought this system & installed it with my cousin. We didn't need to buy any tools we didn't have except for a large drillbit. We did need to extend the electric but did it ourselves. It was hot this past summer and the system kept up even on the hotest days. The only reason I didn't give it 5 stars is that the heating isn't able to warm my space when the temp goes below around 30°F. I'm in South Jersey near Atlantic City. But I'd recommend this system based on the 5 months I've been using it.

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!

We have a flat-roof house built in the 1970s with no central air or heat. I installed this myself in an afternoon and it's been awesome. We live in a moderate climate but need some cooling and heating and this more than does the trick! Installed in a 400 SF room but we have an open floor plan and it cools the house with ease. Installation was pretty straightforward and I purchased a few accessories (non fuse junction box and electrical whip) and I had no trouble hooking it up.

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.

Have had it since mid summer. The air conditioner works really well, cools 350 sq ft easily. Have been using the heat for a couple of months, it heats but if the temperature dips below 15 degrees it's not as efficient. My only complaint is that the remote just quits sometimes, then starts working later. Good thing I have the app on my phone.

I installed this unit in my home in August, 2018. A/C works fantastic! Cools my entire home, with the aid of a box fan to circulate back the hallway to the bedrooms. Very efficient too! My electric bill was quite a bit lower than when I used our central air unit. (It was a 30 year old Carrier and it finally died..). I used the heat pump function as a back up for my wood stove. Works very well as long as the outside temp is 30 or above, which is normal for a heat pump. They are not built to handle frigid weather so the woodstove was necessary from December through February. Installation was simple but having a second person to help is pretty much necessary. This is the largest unit that DIY sells. Smaller units would probably not need a second set of hands. Overall, I am very happy with this unit!!!!

I bought it this past spring (April) used it a lot this summer. Worked amazing cooling our large family room plus kitchen and other areas of the house. Currently using the Heat pump to supplement heating the family room, hoping to lower my heating oil bill. Was easy to install and saved a lot of installation cost.

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..

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>

MRCOOL is performing great. It was easy to install although I did seek help from my local HVAC service. It takes two persons of moderate strengh to lift into place.
