Our air contioner wasn't working and I checked everything on the check list they gave us with the unit before calling.  One thing that wasn't on the list and didn't occur to me was to check for signs of freezing.  This little tidbit would have saved the AC guy a trip out and would have saved me about $60.

Aparrently our AC unit has a freon leak and froze up solid.  The guy came out, took one look, switched the unit off and told me he will have to let it melt over the weekend and come back on Monday to see what he can do.  Luckily, the weather just cooled off immensely so we are not likely to need it until after it gets fixed and possibly not until next Summer.

Home ownership, it's always something!
