Class C with excessive heat on floor..help!

Thanks for all the help! Shout out to Navegator as I think you may have hit the problem. We recently had it into a shop to recharge the a/c and when we got it back, I remember thinking that the housing cover looked a bit off. I will check this right away and report back.

@Sljkansas: that radiant barrier looks great..I'm going to get a roll and install. Thanks much for the suggestion and link.
