Today while replacing the air filter in my home's HVAC, I stupidly left the system on "auto." It kicked on and sucked in a folded piece of glossy paper that was the on floor before I could do anything. There's no way for me to reach into the intake due to the (cramped) design of the area. The system is still running and I haven't heard anything out of the ordinary, and so far as I can tell the paper hasn't made its way to any of the vents in my house.
Is this something I should worry about, or just let it be. That said if it's something I need worry about I guess I need to call someone, and if so--what do I tell them?
