Sucks. Whenever I get central A/C I really want to do my research and get a solid unit, I find I hear a lot about people having trouble with newer units, guess they don't make them like they used to.
Especially here, last thing I want is spending that money and it breaks down the 1 week I really need it.

My portable unit has been holding well though, it's probably close to 5 years old now. It's so loud though, and it won't do the whole house, but at least will do a part of it and help bring the worse of the heat down on hot days.
