My air conditioning fan stopped spinning sometime during the evening.  The morning was already warming up the house and it was going to be a 100 degree day.  Everyone else was really busy and could not get to me until next week.  David told me he was in the area and could take a quick look to try and help me out.  The problems were fixed within the hour and I was quite impressed on how reasonable the bill was for the repair.  I will be using them from now on.
