Twice a year, I pulled up the air vent covers. I clean the air vent covers in hot soapy water, as well as then the two of us vacuum the ductwork. I try to get the air vents as clean as I can, but once every more than one or 3 years, I’ll call the Heating as well as A/C supplier as well as have them come to the apartment to clean as well as sanitize the ductwork, they inspect the ductwork before cleaning, as well as look for any holes or cracks. They have a special adhesive they can blow into the ductwork that will connect to the holes as well as cracks as well as heal them over. This year, I was calling the Heating as well as A/C supplier as soon as I cleaned the air vent covers as well as the ductworks. I was cleaning them in my teenaged daughter’s room, as well as I was getting angrier by the minute, however she wasn’t supposed to be chewing gum because of her braces. I was not just finding chewing gum wrappers in the ductwork, however there was chewing gum hanging off the bottom of the air vent covers, and when she got home from school, I confronted her. I wanted to guess where the chewing gum came from. She wanted to guess why I was in her room without telling me first. She knew I cleaned air vents, so I ignored the question. I told her that if I found out she was chewing gum again, I would make sure she wore the braces to her senior prom. If I found gum in the air vents again, she would be athletic activitying it in her hair, just care about a new hairdo.
