The other day when I was cleaning around the household, I seen this enormous spider plus it ran into the ductwork! I was mad because there was no way I could get to him plus for all I knew, there could be a whole family of spiders inside the ductwork! I made the decision to call a Heating, Ventilation & A/C contractor to ask about ductwork cleaning. They said that would not be a problem! So before I knew it, I had a couple of Heating, Ventilation & A/C workers over with these bizarre looking vacuum tools. I believe they were designed for the purpose of cleaning out the system of ductwork. They even took pictures of the before plus after conditions of the ductwork plus I was especially amazed. My ductwork was so filthy, it was no wonder there were spiders plus other types of bugs hanging out in there! After they were finished with the cleaning, it looked super clean! Also I noticed that when I ran my Heating, Ventilation & A/C device afterwards, the air quality was so much better. It made sense too because all of that dust was not being pushed into the air any longer. I really must say, after seeing those filthy pictures, there’s no way I’m letting my ductwork become that filthy ever again in the future! I also believe that it would be a good move to invest in an enjoyable air purification system. That would absolutely help keep all the dust plus allergens out of the air so I can breathe easier in my household. I like to keep things totally clean in my house, however it seems that I need the professionals to take care of that ductwork at least once per year!
