The other day when I was cleaning around the household, I seen this sizable spider and it ran into the air duct! I was furious because there was no way I could get to him and for all I knew, there could be a whole family of spiders inside the air duct! I thought it would be best to call a Heating and Air Conditioning contractor to ask about air duct cleaning. They said that would not be a problem! So before I knew it, I had a couple of Heating and Air Conditioning contractors over with these weird looking vacuum tools! I recognize they were designed for the purpose of cleaning out the system of air duct. They even took pictures of the before and after conditions of the air duct and I was seriously amazed. My ductwork was so incredibly filthy, it was no wonder there were spiders and other types of bugs hanging out in there! After they were finished with the cleaning, it looked amazingly clean! Also I noticed that when I ran my Heating and Air Conditioning appliance afterwards, the air quality was much better. It made sense too because all of that dust was not being pushed into the air anymore. I really must say, after seeing those disgusting pictures, there’s no way I’m letting my air duct become that filthy ever again! I also recognize that it would be a fantastic idea to invest in a great air cleaner. That would truly help keep all the dust and allergens out of the air so I would be able to breathe easier in my dwelling. I prefer to keep things especially clean in my house, however it seems that I need the professionals to take care of that air duct at least once every year!
