Hearing strange noises behind the walls while vacuuming

I recently was going to have a bunch of my friends over for a get together.

I was setting up the apartment and getting everything ready. I was cleaning like crazy when I heard a weird noise. I thought it was me with moving furniture around so I did not think anything of it. I kept hearing it though. I heard it even when I was not moving furniture. I thought it could not be me. I turned the vacuum off to hear the noise. I tried to follow it and I ended up listening against the wall. I knew the sound had sounded like that of a collapsed air duct behind the wall. I waited until my HVAC system kicked on again. I also noticed that the nearby air vent had be releasing much less air than it had been before. I knew that some of the air was getting lost and not getting into my house. This was when I realized that I needed to call my HVAC technician right away. I did not want this issue to progress any further than it had been already. It was causing the system to make unpleasantly loud noises and I was not fond of it at all. The HVAC technician told me it would take some time to replace it since they would have to take part of the wall out. I did not want them to do this but I felt that I had no other choice just then. It was a bit of a messy process but it had all finally been done and it was finally over with as well.
