Why Dryer Vent Cleaning Is So Important for Safety and Efficiency

If your dryer is taking longer than usual to dry clothes, or you notice it’s running hotter than normal, your vent might be partially blocked. Lint buildup reduces airflow, forcing your dryer’s blower motor to work harder. This not only increases energy consumption but also causes extra wear on the appliance — potentially shortening its lifespan.

The problem is even worse in homes where the dryer is located on a second floor or away from an exterior wall. Longer vent runs mean more opportunity for lint to accumulate, and bends in the ductwork can trap debris more easily.

Beyond performance issues, lint buildup poses a serious fire risk. Lint is highly combustible, and when it collects near the dryer’s heating element, it can ignite. In fact, dryer vent fires are one of the leading causes of house fires in North America each year.

Regular cleaning removes that risk, ensuring your vent stays clear and your home stays safe.

As a general rule, dryer vents should be professionally cleaned every three to four years. However, depending on your home’s layout and how often you use your dryer, you might need to clean it sooner.

You should schedule a cleaning right away if you notice:

• Clothes take longer to dry than usual

• A burning smell when the dryer is running

• The exterior vent flap doesn’t open properly

• The dryer feels unusually hot to the touch

If you’re unsure when your dryer vent was last cleaned, it’s better to book a professional inspection now rather than wait until there’s a problem.

While some homeowners try to clean dryer vents themselves, professional cleaners have the right tools to reach long or complex vent systems safely. They can also inspect for damage, disconnected ducts, or lint buildup that DIY tools can’t fully remove.

Hiring a professional every few years gives you peace of mind — knowing your dryer is operating efficiently and your home is protected from potential fire hazards.

Dryer vent cleaning isn’t just about better performance — it’s about protecting your home and family. Even if your lint trap looks clean, lint buildup inside the vent can still restrict airflow and create a dangerous fire risk.

Schedule a professional cleaning every three to four years to keep your dryer running efficiently, extend its lifespan, and maintain a safe, energy-efficient home.
