How to Tell When Your 
Dryer Vent 
Needs Cleaning

Keeping your dryer vent clean is crucial for both efficiency and safety. A clogged dryer vent can lead to longer drying times, increased energy bills, and even pose a fire hazard. Fortunately, there are several telltale signs that can alert you to the need for a cleaning. Here’s what to watch for:

Extended Drying Times

If your dryer is taking longer than usual to dry clothes, it’s often a sign that the vent is blocked. Proper airflow is essential for efficient drying, and any obstruction can significantly extend the time it takes for your clothes to dry.


When a dryer vent is clogged, your dryer may feel unusually hot to the touch after a cycle. This overheating can cause wear and tear on your machine and pose a potential fire hazard.

Visible Lint

Examine the outside vent while the dryer is operating. If you see little to no lint exiting the vent or lint is accumulating at the opening, this is a clear indicator that the airflow is restricted due to blockage.

Burning Smell

A burning smell coming from your dryer is a serious red flag. Lint, which is highly flammable, may be getting too hot if your vent isn’t exhausting air properly. Turn off your dryer immediately and inspect the vent.

Dryer Stops Mid-Cycle

Some dryers are equipped with a high-temperature safety feature that turns off the machine when it overheats. If your dryer stops before the cycle is complete, it may be an indication of a blocked vent.

Excess Lint Behind the Dryer

If you notice an unusual amount of lint accumulating behind your dryer, it could be due to a clogged or disconnected vent. This lint should normally exit through the vent but may be backing up instead.

It Has Been Over a Year

Even in the absence of these warning signs, it’s wise to clean your dryer vent at least once a year as preventative maintenance.

If you notice any of these signs, it’s time to clean your dryer vent or call a professional to ensure it’s done properly. Regular maintenance will help extend the life of your appliance, save energy, and most importantly, reduce the risk of fire in your home.
