Great purchase for my bedroom. I have a 3 story house with central air conditioning but my bedroom doesn't get cold enough for me. This size unit works perfectly for a bedroom. And now I sleep so soundly and comfortable and must say.

Susan J. 5/5 Verified August 11, 2024

DELLA Fenestra Series 6000 BTU Smart Window AC with Remote/App Control, Cools Up to 250 Sq. Ft

Got this to supplement my central AC that doesn't work efficiently in Georgia summers. Just wanted to keep my bedroom at a good temp so I don't run up the electric bill cooling The entire house. This little S.O.B. freezes out my bedroom. Even set at 71 it's cold. So I'm satisfied. Just not sure it's ECO mode actually works. The diverter on the front is for show only, it doesn't really move and tends to vibrate when the unit is running.
