A coil frame or casing gap can dump conditioned air into the ceiling and whistle. Shut down, clean the seam, fasten the frame, and seal with the approved temperature-rated sealant/detail.
VAV [tag] is leaking/whistling around the reheat coil casing. I checked the frame gap and safety status. Do you want it fastened and sealed with the approved temperature-rated detail?
Watch out
Do not seal around live electric heat or moving equipment without lockout/safe direction.
Check
Shut down or make safe before working near electric heat or hot water components.
Locate the actual casing gap and check whether the frame is loose or damaged.
Clean oil/dust before sealant.
Use approved sealant/gasket for the temperature and equipment section.
Retest for whistle/leak after the fan runs.
