This bag of flex was left connected to the main duct but not run into the sales floor.  A small oversight that could have been a huge energy loss.

Cracked and worn fan belt, also the motor bracket was cracked.  This building was paying a maintenance contract, they have since switched companies.

Outside air fan filter completely loaded causing humidity issues in the building.
