I think Mr. Air has to come back, unless the tepid air that's blowing gets colder. I think what we'll need to do is have me start it up and if it's not blowing cold then he can come and I'll leave it running. If it IS blowing cold, then we'll wait until it screws up again. I'm hoping it gets colder in a few minutes but for now it's not really cooling things down. At least it's not hot air like over the weekend.
