Rated 3 out of 5 by from It works well This air conditioner cools very well but after only 3 months it went out. Luckily it was covered by the manufacturers warranty. They sent a local company out and they took it and fixed it in a couple days. And now it works better than before. This was a replacement for an older frigidaire air conditioner my only complaint now is that there is no vent for when it is nice outside and I just want it to blow in fresh air instead of cool. Like the older model had.

Rated 4 out of 5 by from Good - Installation instructions could be clearer Good AC unit, good features. Some installation instructions and associated drawings are either unclear or not specific to the unit I bought (example: details of exterior window ledge hardware/use therof). I was able to work it out and all is well.
