This is an absolutely amazing air conditioner. It works so well. It will not only keep one room cool, but it will keep the entire house cool. It is a very powerful air conditioner that can get it as cold as you like or at a warmer temperature if you prefer. The climate control keeps it at whatever temperature you want and this thing does an excellent job of keeping the whole house cool during a really hot summer. I love this air conditioner and am amazed at how powerful and efficient it really is. It also has an automatic timer on it so you can have it shut off whenever you want so it doesn't use too much energy. An+yone who needs a good air conditioner to keep their house or just a big room nice and cool, this is the one for you. .
