No, air ducts and dryer vents are not the same. The dryer vent is connected to a specific appliance, the dryer, and is meant to direct the hot, moist air from the washed clothes to the outside of the home. Air ducts move air from the HVAC system around the home. It’s essential to schedule cleanings for the dryer vent and the air ducts.

A burnt rubber smell coming from your clothes after they’ve been in the dryer can be the result of too much lint in the lint trap. This prevents air from circulating properly, and the lint may even come into contact with the heating element. It could also be the result of bigger issues like a faulty thermostat or worn-out dryer belt. A burnt rubber smell can even come from elastic waistbands or rubber decals in your clothes. To remedy this, dry clothes on a lower heat setting or allow them to air dry instead.

If you happen to disassemble your dryer vent and feel the inside of the duct immediately after drying a load of laundry, it will likely feel damp and warm. That’s normal, as the vent has just finished moving the humidity and moisture from your laundry to the exterior of your property. However, if your dryer vent has water droplets in it at any time, it’s a sign that there’s trouble with the machine’s ventilation. You should call in a professional right away to get the issue fixed.

Depending on how much you use it, your dryer should be disinfected about every six to 12 months, especially if you see frequent buildup of lint or evidence of stains from fabric bleeding or ink. 

Other signs you should sanitize your dryer more often are overheating, improper drying, excessive humidity, or if you notice a strange odor when it’s running.
