My dryer vent won’t vent properly

They use a snaking apparatus

I am now doing more laundry these days after noticing that our flu symptoms were getting worse. At first nothing I did helped our symptoms abate. I dusted all of the surfaces in our home, I was sweeping plus mopping the floors, plus I was vacuuming the carpets all at least once per afternoon or more. I assumed that doing all of those things would help me quit suffering from respiratory issues plus sinus congestion, but none of it did. My medical professional told me that we should install an UV air purifier with a HEPA filter plus UV-C bulbs for additional air cleaning, but even that didn’t completely fix our symptoms. The UV air purifier helped more than anything else, but it wasn’t enough. Then our medical professional advocated that our clothing plus our bedding could be worsening the allergic reactions. I changed the detergent to a better brand plus then I immediately noticed our complications started to lessen. They were better than they’d been before. After I got the same results with every load of laundry several loads in a row, I decided that I should go and rewash everything in our house. The only issue I have now is that the dryer isn’t working well. It seems as if I have to leave the loads in the dryer for hours. I asked our Heating, Ventilation & A/C business if they handled dryer exhaust vents. They told me they could send someone out the same afternoon. They use a snaking apparatus. The HVAC specialist did all of the work outside plus never had to move our dryer to get access to it. After she said she was finished, she told me to turn on our dryer for an hour to get rid of any additional dust that didn’t come out with the ventilation snake. Now that our dryer vent is clean, it only takes 45 minutes to get a load of laundry bone dry.
