Hot Hot Hot (Air conditioning)

Today is so hot! Yesterday, the 4th of July, we noticed that our air didn't seem to be working. Today, we confirmed our air conditioning is not working... It's hot! Needless to say, being a holiday, no one is going to come and visit without charging a crazy amount. Mr. Beirman came and looked at it and said it may have finally given out... it may be dead!!! It's hot. He said this after I explained that two days ago I heard a loud pop and a hissing sound. I should have thought that meant something, but no one else seemed to hear it and I dismissed it. It's hot!!! At least we will probably get a new air conditioning unit if it died. It's HOT!!!!!!!!
