We have seen this over and over.  Equipment on a rooftop where a manager or owner can't see what is going on.  This is how this rooftop was left when the technician of an unnamed company left for the day and said he would be back the next day because he was hot.  Yes it was hot.  Real Hot. .  But customers want to be cool when they are spending their money.  We got this mess up and running by the dinner hour.  Call us.  We can fix it right.
