I want to get the air duct cleared however our spouse is totally against it. My side is that I have done a whole lot of home remodeling. I have completely gutted a lavatory where there was dust all over the place. Every ceiling in our home had mold that I scrapped. I even mudded & sanded a few of the ceilings. I also sanded wood bifold doors in the home as well. There has been a lot of dust flying around & our air conditioning was on for all of it. I think the Heating, Ventilation, & advanced A/C took in that dust & now it is sitting in our air duct. Did you know that both of us spend 95% of our afternoon indoors? Did you think that the air quality in our home is almost 5 times worse than the outdoor air? I want to have pristine indoor air conditions. I don’t want to breathe in all that dust to make myself and others sneeze & feel quite sick. That is why I feel both of us need our Heating, Ventilation, & advanced A/C ducts cleaned. I have the money & the time to babysit the Heating, Ventilation, & advanced A/C worker. My partner is of the belief that the air duct is safe. It is totally sealed in the walls & ceilings. It is not affected by dust that can kneel inside of it. Having a worker do air duct cleaning is just dangerous too. They can particularly damage the Heating, Ventilation, & advanced A/C ducts in the process & cause some holes. A small hole can let out a lot of air & cause energy huge bills. Even perfectly sealed Heating, Ventilation, & advanced A/C ducts let out 10% of the air the Heating, Ventilation, & advanced A/C creates. A quality section of the air duct is letting out 30% of the air. Crazy isn’t it? My partner doesn’t want to risk ever higher energy bills.
