Mainstays 5,000 BTU window air conditioner is rated 3.7097 out of 5 by 31.
Rated 5 out of 5 by from Excellent I bought one of these last year for the bedroom and another for my daughters bedroom two weeks ago. I have to admit, these units are great. They are quiet and easy to install. I just might buy another one this upcoming week. I have absolutely no complaints.

Rated 5 out of 5 by from Great for an apartment My boyfriend & I live in a medium sized apartment. We were worried about the specification on the box saying it was made for "small rooms" as we wanted to put it in our living room which is quite big and open. We live on the top floor of an apt building & the heat was becoming unbearable this summer so we got this because we're on a tight budget. It works INCREDIBLY. When you walk in, the cold hits you right away & it feels so comfortable in the whole apt. Much more powerful than we expected it to be. Would definitely recommend this!!!

Rated 5 out of 5 by from Great little AC! Great little AC! Was a snap to install (I have casement windows so it's tricky to put an AC in.) The unit is small and very quiet, but it's a workhorse! It's early June in southern Ontario and the temperature outside is 23C/28C with humidex (72F/82F w/humidex) it is a cool 21C inside my living room with no humidity. I left this running on low all night and had no idea it was so sticky outside until I opened the door! My house is smallish; about 1200sqft with an unfinished basement; and this keeps nearly the entire upstairs cool. The energy guide says this will cost $46/yr based on 8h/day for 3 months based on an average $0.12kwh I expect this to cost me about $45 month if it's run 24/7 (which it won't be). I'll gladly pay that to be comfortable this summer. Best purchase this year so far!! FYI for those who have casements: Instead of plywood, try foam sheet insulation. Its waterproof, easy to cut, fits snugly in the frame and its paintable.

Rated 5 out of 5 by from Love It. We purchased one as a test and ended up purchasing a second one. We don't have to use the highest level to cool the room.

Rated 1 out of 5 by from Poor quality but very quiet I bought this air conditioner for my bedroom, and find it very quiet. The quality of the unit is poor however, and the compressor only activates when turned on the highest setting.
