I bought this window unit in April 2025 and used it during the Spring, Summer, and early Fall of that year. This year (2026), I used it for several months (April and May), but no longer have use for it. It's a 6000 btu unit and I believe it's rated to cool a 250 square foot room. It did a decent job of cooling an over-sized room. The ECO mode did not work for me: it was cycling on and off every five minutes (and not getting the job done), so the unit was run 24/7 (without cycling on and off). I do not have the accordion panels that came with the unit. Get back to me if interested. I have very limited time to show this a/c.
