Am I glistening?

Our A/C is acting up. Right now, it's not acting at all. It's actually pretty nice outside, but the air in here is not circulating so well. I'm hot. Or warm. Sleeping tonight might be a challenge. We have an A/C guy coming tomorrow to check it out. PLEASE let it be a relatively inexpensive fix! We don't have the time or money for this kind of crap right now!
