Summer Days

We have a lot of problems with my air conditioning in my condo in Sacramento.  Our condo has two stories and it is really difficult to cool the first story and the second story evenly.  It's a problem because my roommates on the first floor are always complaining that the air conditioning is making it way too cold downstairs.  They are always turning it off.  Meanwhile, we are boiling upstairs on 90 degree days in the middle of July.  It is really frustrating and we are not sure what to do.  We have complained to management several times but it is really difficult for them to do anything because there is not anything wrong with the air conditioning.  It is more a problem with the layout of the condo.  The roommates downstairs get really frustrated because they are paying to have the air conditioning running when they do not need it.  We always get frustrated because it is impossible to try and get ready to go somewhere and look nice when you are already dripping in sweat the second you step out of the showing.  At this point, we aren't sure what we are going to do.  But we will have to figure out something pretty soon.
