Great DIY Solution
Great product and great service. Installed a 12,000 BTU unit about two months ago. Install was straight forward. Watched videos on YouTube and was very easy. Highly recommend!!

The directions are pretty much useless, just YouTube it.
This system was so easy to set up, pretty much any homeowner with a crescent wrench and a holesaw can do this job. My kit said it came with a whole saw, but it did not, make sure you buy the complete holesaw when you get one.

Defect (leakage in the inside unit) and not supportive customer service
The media could not be loaded.
DIY products need strong customer support.My MRCOOL is less than one year old.My MR COOL product has a defect, leakage; see the attached video.I tried recommended things (cleaning drainage and filters) to fix the problem, but nothing worked.It is hard to reach out to the customer service center by phone.They finally refused to fix it because I am the second owner.

Fantastic
Best mini ever

10 degrees cooler on a 108-degree day in no time!
This mini-split is a game changer!!! Minus some supply voltage troubleshooting on the homes end, the entire process went smooth. As with all instructions – you do have to be flexible & handy. Really simple install when the process gets planned in advance. Tech-support is tops considering that we are in peak-heat season. Even though the flaws found were on the home-owners end, Mr. Cool rep worked to find us resolve until we were up and running. Not a product problem as this thing is A+. The unit outperforms & replaces 1 portable and 2 window units in our old farmhouse and draws fewer total amps!
