I have bought two of these Frigidaire Window Units. It starts cooling immediately. It can be set as low as 60 degrees, has a remote control, and it will cool several rooms. Love this AC! I have also bought a smaller one for another room. I highly recommend this AC unit! It really is icy cold!! Memphis is hot and humid. It has already hit 100 several days in a row. This one unit is all we have right now for 4 rooms and our hallway. We are very comfortable, even will the sweltering heat outside. It blows very hard, and very cold. If you are looking for a powerful AC, this is the one.

I have two of these units in my 3200 square foot top floor loft (which always gets the hottest) with 15 foot high ceilings, and they are FANTASTIC! They start cooling almost immediately, even in the middle of a 95 degree heat wave. Very nice looking units as well, I like the fact that the remote control shows you the ambient room temperature even when the unit is not on. Very easy to install, I did it myself (I am a 120 pound woman) and only needed the hubby to help lift the unit to the window after I had put in the sleeve. The hardware provided is very secure, I have no fears whatsoever of the unit coming out of the window. Shop around though for the best price with shipping and tax (if any). Also do your research and make sure you have the proper outlet for this unit and your window can accommodate it.

We don't have a very big home and this air conditioner works well to cool down 2/3's of our home (the other 1/3 is shut off and has an air conditioner of its own). I highly recommend it if you have about 1000-1100 sq/ft to cool.
