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'.

When I bought this unit everyone said it wouldn't last a month. It almost made it a month before the blower motor for the inside unit went out. They sent me another motor right away. No instructions for replacing the old one, however. Needless to say, it's a difficult chore if you are not an ac service tech. If I hadn't found a video on YouTube , I probably could not have repaired it. Very slow response from the company that sold it to me. It was an Amazon purchase filled by someone else. It has worked fine since the repair. But I have no confidence in the unit after it failing in the first month. I wouldn't buy it again.

Very happy with unit but install went very hard made for 2x6 construction not 2x4 if they had flex go into wall and connect inside would have made install a lot easier . Kinked piped trying to bend and had to have friend cut and reconnect pipe . Need thre people to help install 24 k unit

Installed by myself last summer and it has worked flawlessly ever since. Only negative would be that the indoor fan runs non-stop which the factory said is correct. I wish it cycled on and off with the outdoor unit. Not so much for energy but rather because it will most likely affect the longevity of the fan motor.

With the crazy hot summers here in Texas, this was a smart investment!! I can actually work in the garage without passing out from heat stroke. Cools off the garage quickly, and I love the articulating discharge. My only wish was there was an option to choose a longer length for the freon lines. It dictates placement of head unit and condenser and required some landscaping outside to hide the condenser from plain view and the HOA.

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!

We got a 2-ton unit for the main part of the house last spring to replace a dead central AC unit that was forty years old. Installed it myself, which cost about a third of what a professional HVAC companies were quoting me. I was worried about failure and warranty coverage, and everybody in the industry tells lies about how bad mini-splits are. They have a HUGE revenue-generating and mature business model they are trying to protect. Don't fall for it. Everything negative they said about mini-splits was a lie. Not only is a MrCool mini split easy to install, it is SO quiet you will not even know it's running, and one unit cooled the whole living area of our house, all summer long. We liked it so well we decided to get a 1-ton unit for our master suite, since it is on the east-wing of our home, away from the central living space. Plus there's an office/gym space with it (converted 4th bedroom) that had a window air in it that worked pretty well, but our bedroom would be too warm on the very hottest nights. So MrCool to the rescue once again. We dumped the old window air and got a mini-split to take over cooling of the entire area. The 12k BTU (1-ton) model is 110/120volt powered, which makes it easy to either route a circuit to it or utilize a lesser used existing one. Units should really have their own dedicated circuit, but it's even easier getting a 110v circuit run. Same deal, it is so quiet you can't even hear it, even when sleeping under it. You do need to point it away from you though or it will freeze you out. LOL All of my worries about installing one successfully, running it, and living with one, were without merit. This has to be THE very best investment/improvement to our home in the 25 years we've lived in it. Plus these two units ended up costing me one-fourth of what the pro's quoted for a new central air system. And yeah, our bill went up in the hottest months, but as soon as we weren't running them 24-7 it dropped right back down. The level of comfort was way worth it. Now, over winter, the hidden benefit of these two MrCool units is that they are a HEAT PUMP compressor so we get nice dry and warm heat to supplant our central gas-furnace. Same deal, they are so quiet you don't even hear them running. And once up to temp the compressor unit (outside part) shuts off and the air handler goes virtually to sleep, just barely turning. Same deal, so comfortable and efficient - even for heat! With MrCool, you just can't miss. A huge thumbs-up!!

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.

Our MRCOOL 24K is installed in a 700-750 square foot living room and during the summer times (in Bellingham, WA USA), it provides an acceptable level of cooling. It is quiet and performs as expected during the summer time. But during the winter, when the temperature goes below 40s, it has a hard time keeping up with the set temperature of 72F and the temperature in the living does not go above 66F or 67F even if it has been running for hours. We need a an auxiliary heating system to compensate.

We bought this unit last summer for an extension on our house. This room would get very hot in the summer and freezing in the winter. This unit keeps this room comfortable all year long and my electric bill is not through the roof. Actually we are considering buying a second unit for our finished basement!!!
