I legitimately had my share of weird and creepy things that have happened while I am at work.
Each 1 of my co-workers has a different strange and weird story, but mine was legitimately recent and it is still fresh in my memory; I responded to a residential a/c repair call, however the lady said that she heard some strange noises coming from the ductwork.
I thought that there might be some loose sheet metal that needed to be taped. I went into the attic so I could see any holes or light that might be shining through. I did not see any evidence of rodents or pests. That’s always a nice sign, because rodents and pests are the number 1 problem that can happen with ductwork. The next thing that I decided to do was remove the vent covers from the section where the lady said she heard their noises. I used my flashlight to look inside of the ductwork and I particularly could not see much at all. I looked inside of the master living room section ductwork and there was nothing, but just above the ductwork between the living room and the master living room, there was an section that was covered with dolls. The ductwork in that section was filled with children’s toys. They were arranged in a weird and strange pattern that looked like it was intentional. I wish I would have been able to take a picture with my iPhone, but I only saw a little bit of light and I had to use a tool to grab all of the junk. It still easily creeped me out.
