FAQ

How often should I replace my dryer hose?

It's a good idea to inspect your dryer hose annually and replace it every 5-7 years, or if you notice any signs of damage.

Can I use a plastic dryer hose?

While plastic hoses are cheaper, metal hoses are more durable and less likely to kink or catch fire. It's recommended to use a metal hose.

Why is my dryer not heating?

A clogged or damaged dryer hose can restrict airflow, causing the dryer to overheat and shut off. Check and clean the hose if necessary.
