Should exhaust ducts associated with clothes dryers terminate outside the building?

1. TRUE

2. FALSE

The correct answer is: TRUE

The termination of exhaust ducts associated with clothes dryers outside the building is essential for several reasons. First and foremost, directing the exhaust outside prevents the buildup of lint and moisture inside the home, which can create fire hazards and promote mold growth. Clothes dryers expel hot, moist air, and if this air is vented indoors, it can lead to increased humidity levels and potential damage to the structure. Additionally, by exhausting air outside, you are also removing the pollutants and odors that can originate from the drying process, thereby improving indoor air quality. Properly terminating dryer vents outside also complies with building codes and manufacturer installation instructions, ensuring that the dryer operates efficiently and safely. In summary, terminating exhaust ducts from clothes dryers outside the building is crucial for safety, health, efficiency, and legal compliance, thereby reinforcing the correctness of the answer that such ducts should indeed terminate outside.
