The Olsen & Smith 12000 BTU 4‑in‑1 portable air conditioner is basically a strong workhorse: not pretty, not silent, but it cools a hot room properly.

It does cool a room, and if you install it properly in a reasonably sealed space, it can bring the temperature down and keep things comfortable during hot days and nights.
