A steel dryer vent typically lasts 20 years. However, usage, maintenance and environmental factors can shorten or extend its lifespan.
Average lifespan of a steel dryer vent
A steel dryer vent can last roughly 20 years because the metal withstands heat and moisture better than plastic.
What affects how long a steel dryer vent lasts
The lifespan of a steel dryer vent depends on factors such as corrosion exposure, installation quality, lint buildup and external environment. These elements influence wear and can either extend or reduce its typical life.
Signs a steel dryer vent needs replacing
Common signs that a steel dryer vent is nearing the end of its life include rust or corrosion, loose fittings, restricted airflow or holes or leaks. Noticing these cues helps you plan for replacement.
How to make a steel dryer vent last longer
To extend the life of your steel dryer vent, follow the manufacturer’s maintenance recommendations. Regular cleaning, proper usage and timely minor repairs can help it serve longer.
When replacement is necessary
If your steel dryer vent shows persistent failures, safety issues or is beyond its typical lifespan, replacing it with a new model is usually more cost‑effective than repeated repairs.
