I wouldn’t say that I’m the cleanest person in the world. I’m no pig, I don’t let anything get too filthy before I clean up, nor do I have any gross habits like leaving dirty dishes in the sink to collect bugs. I certainly don’t compulsively clean or panic about my house being disordered, but I do keep everything in reasonably clean conditions. I try very hard to keep things neat and orderly, but it is a struggle each and every day. That’s why I was getting excruciatingly frustrated when a layer of dust and dirt kept appearing on every surface around the house. It seemed like my cleaning efforts were never enough, and I was having to perform them more and more often without seeing any major difference in the quality of my home. I couldn’t figure out why it was suddenly so dirty all the time, until a saw a piece of lint dangling off of my air vent. Upon closer inspection, I realized that the air vent was completely filthy, inside and out. I shone a flashlight into the ductwork and was shocked to see a buildup of dust and debris inside, and called my nearest HVAC professional immediately. He came out with a strange looking piece of equipment and promptly began vacuuming the ductwork throughout the house. He told me that the filth I had been experiencing was supplied by the dirty air vents every time my furnace kicked into gear and recommended a maintenance package to keep my ducts spic and span. I’ll do anything to clean less; I signed up right then.
