It only takes about 5 minutes to set when the power goes out. Since I used foam insulation when built the house we close the bedroom doors and it keeps the rest of the house cool. Can't believe it puts out 42 degree air.
This a/c has worked well in my apartment, but the amount of effort to vent it is minimal. Many condos/apartments don't allow window a/c's, so this is a wonderful solution.
Best money ever spent!! We use it in our master bedroom so we can turn off the central air at night. It blasts cold air and is very efficient at cooling our room fast even with our high ceilings. Our room is about 300 sq feet and it stays nice and cool during the hot summer nights! The fan works well also with the room temp air that flows when it's cooler out. The noise level isn't too bad and it definitely helps block out the outside noise (dogs, trucks, etc). The remote works just OK and doesn't always register a change but it does turn it on/off so you won't have to get up and do it. I highly recommend it!
