Reviews for MRCOOL DIY 4th Gen 12,000 BTU 22 SEER Ductless Mini Split AC and Heat Pump with Wireless-Enabled Smart Controller-R410A

Easy to install myself. Ran great for 16 months. Kept an insulated building 12'x34' at the set temperature. Iced up the indoor coils. Refrigerant leaked somewhere. Cheaper to replace than repair. Expected longer life. Tried to contact MrCool but no help within a week.

I love the product, was easy to install. You guys nailed this DIF product.

The unit works great, and was relatively easy to install.

I've tried literally every setting this device has to offer, it never keeps the room at the right temperature. If it's set to "Cool" it cools constantly, no matter what temperature you tell it to stop at, it just keeps making the room colder and colder until you turn it off. Set to "Auto" and it never cools at all, the room can be 80 degrees, Mr. Cool is set at 73, it never cools the room at all. The only way it works is to constantly manually turn it off when the room is cool enough then manually turn it back on when the room gets too warm. Terrible device, should have just bought a floor standing cooling system from Home Depot instead, would have been the same level of useless at 1/3rd the price.
