Where must clothes dryers exhaust to?

Clothes dryers must exhaust to the outdoors to ensure safe and effective operation. This requirement is crucial because when dryers vent indoors, they can release moist air, lint, and harmful gases back into the living space, which can lead to humidity problems, mold growth, and poor indoor air quality. Outdoor exhaust helps to eliminate these issues by directing hot, moist air and lint away from the home, reducing the risk of fire and promoting proper airflow. Additionally, most building codes, including the North Carolina Mechanical Code, specify that dryer exhaust ducts should terminate outside to promote safety and efficiency.
