HVAC unit - air blowing out of cabinet

Hi all,

Found an odd situation today, we found a significant amount of air blowing out of the air handler cabinet but not where its supposed to.

The air was blowing out of the port in the photo to the immediate right of the condensate line (white) and around the suction line opening.

I’ve never found this before. Any ideas?



yes, seal them

I always see them sealed.

Some one pulled the plug to do some cleaning and forgot to re-install it, just a suggestion.

Looks like they forgot to seal the areas with thumb-gum when they were using a half of a roll of silver tape to connect their plenum.

Thanks guys!

Don’t forget to fix the armoflex on the suction line
