How Often Should You Clean Your Dryer Vent?

The general rule: once a year

For a typical household, cleaning your dryer vent once a year keeps it safe and efficient. That schedule clears out the lint that builds up with normal use before it can restrict airflow or become a fire hazard.

When you should clean it more often

Several factors mean your vent fills faster and should be cleaned every 6–9 months:

• Large or busy household — more loads per week means more lint.
• Pets — pet hair adds significantly to buildup.
• A long or winding vent run — common in two-story homes and roof exits; lint has more places to collect.
• A high-capacity dryer or frequent bulky loads (towels, bedding, blankets).

Signs you're already overdue

No matter the calendar, clean the vent now if you notice clothes taking two cycles to dry, a hot laundry room, a burning smell, or lint around the outside vent. We cover these in detail in 7 warning signs of a clogged dryer vent.

What a professional cleaning includes

A proper cleaning isn't just emptying the lint trap. At FreshFlow we clear the full vent line from the dryer to the exterior, test airflow before and after, and finish with a fire-safety inspection. If we find a bird nest, a crushed transition hose, or other issues, we show you and quote it before doing anything extra.
