history: My a/c went out and I called a repairman. He was not able to fix the problem. I called out a repairman to fix my a/c today. Oh no_comma_ your a/c isn't working?! This is a bad time of year for that!
current: No.  He couldn't figure out what was wrong.  It is very hot out today too.
next: Man that's awful, I'm sorry. I hope you're able to get it fixed, and soon!
