Good vid ... if possible... might be a good idea to do a Early morning coil clean on that one. a Reverse wash with some coil cleaner ... i'm thinking coil has never been cleaned... and is impacted a bit.
I have to ask you know Velma and Freddy and Thelma and Scooby cuz I've decided you must be Shaggy cuz you're always running around in that van and always solving the mystery. And every time you get done the mystery solved. But the only problem is it's not an old man in a mask. But it's a masked problem! Another great job take good care of yourself. And go have you a Scooby sandwich
