Misc. Comments
AHU-8- Rubber flex connector between the unit and the ductwork has a large hole and air is leaking through. This is a repeat finding and has been reported before as part of the previous inspections findings.

A control panel has no front cover in the mechanical penthouse in which AHU-3 is located.

Portable #137- All supply air diffusers are shut and because of that air has no where to go and making a whistling sound. This can damage the unit.
