If it’s taking longer than usual for your clothes to dry or the clothes are super hot after a dry cycle, you could have a build-up of lint—even if it’s not visible in the lint screen. “Lint is an extremely flammable material,” says Jason Kapica, president of Dryer Vent Wizard. “Oxygen moves through a dryer and its vent when the machine is running. There is a heating element inside the dryer providing a potential ignition source.” Reduce the risk by removing the lint from the lint screen after each load and get a yearly cleaning of the dryer vent line. Also, make sure to never put any of these 14 items in your dryer.
If you notice some puddles on the floor (and you don’t have a new puppy), it could be a sign of poor ventilation and mold. “Mold is a particularly common problem in bathrooms with inadequate ventilation,” says Yoel Pioraut, managing partner at MyHome Design + Remodeling. “Examine pipes to check for moisture or excessive condensation. If everything checks out, but you have a lack of ventilation, it’s time to call in a contractor to add an exhaust fan,” recommends Pioraut. Allergies and asthma reactions are intensified when mold is present.
