Oh here’s something I can share with y’all but not on Facebook/Instagram/etc. I shoved my phone down a duct after changing the filter to judge the health of the duct, mostly to make sure it wasn’t coated in dust or something from misuse of filters etc etc etc
And on one side I found an ice cream bucket IN THE DUCT and on the left of the divider I found a metal pie tin (which in modern times is made of aluminum, not tin, but hey).
I immediately went to show the pictures to my mom because i was bewildered and she told me that my dad used to fill things with water and shove them in the duct to humidify the air. So now im happy i don’t see huge spots of mold on the exposed, unlined wood.
Unfortunately I have not been able to get them removed yet, and it’s low on my list of priorities (even though the ice cream bucket appears to be a third of the way full with... something... probably dust that got trapped in what was water???)
I will update if y’all are curious
