Arrived on time and well packed.
I purchased the MRCOOL DIY Select 24,000 BTU system for my large living area, and it has been working great. It cools the room quickly, maintains a comfortable temperature, and runs much quieter than I expected.

Directions
Fairly easy to install some directions said to use 3 1/2” hole but on template it was 2 1/2” which is what I used. Some of the other directions not to clear, still not sure where the little black filter goes?

Great system, but I wish the Wi-Fi app was a little more polished. Otherwise, no complaints.

Nice little unit. It’s not as powerful as the larger ones of course, but for a small room, it does the job well.
