Quiet, efficient split; but mold issues and bulky.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
They suuuuuuck, I'm constantly having to "live mix" whatever I am watching in the living room due to the sound because it has an eco mode so it will turn on/shut off when it hits a certain temperature threshold. Plus it won't get my living room below 75° I mean they work for what they are, but I purchased a portable Toyotomi dual hose system and that thing rocks. Way less noisy too
“Best” and “portable a/c”, nope. But Toyotomi if you can find one.
