Is it to get followers and make suckers destroy their central heating and a/c plan? Those folks will have to pay thousands to get a replacement current central Heating, Ventilation and A/C unit

I came across some information the other day on how I can save money if I clean the ductworks of my central HVAC. There was a video online about this showing how to get an extended length pipe cleaners used for my backyard water hose. The whole video looked fake, like it was all staged or something. I know it’s better to get a HVAC specialist to clean the ductworks of my central heat and a/c unit. I’d never even once tried to scrub the ductworks of my central HVAC unit all by myself. The truth is I don’t know anything about such work. Plus, I could see myself flooding the ductwork or something. I don’t know why people on the internet post videos in this manner. Is it to get followers and make suckers destroy their central heating and a/c plan? Those folks will have to pay thousands to get a replacement current central Heating, Ventilation and A/C unit. I just simply do not get it or understand it! But, I would never even once attempt to wash the ductworks of my central HVAC unit myself. That is crazy. So I’m writing to educate people not to try it if you come across these videos.
