If your dryer used to finish a load in one cycle but now seems to run forever, you’re not imagining it. A dryer taking longer to dry clothes is one of the most common signs that something may be affecting airflow.
It’s easy to dismiss the problem and simply run the dryer for another 20 minutes. But longer drying times can be more than an inconvenience. They may indicate restricted airflow, which can make your dryer work harder, use more energy and generate excessive heat.
As a local dryer vent service company serving homeowners across Toronto, Winnipeg, Mississauga, Edmonton, Brampton and Calgary, we see this issue regularly. Here’s what may be happening—and why it’s worth paying attention to.
Why Is My Dryer Taking Longer to Dry?
Your dryer needs good airflow to remove warm, moist air from the drum. When that airflow is restricted, moisture has a harder time escaping, leaving your clothes damp for longer.
One of the most common causes is lint buildup inside the dryer vent or duct.
Over time, lint, dust and debris can accumulate in the vent system. This can reduce airflow and force your dryer to work harder and run longer.
Other possible causes include:
- A clogged dryer vent
- A vent duct that is kinked, crushed or blocked
- Lint buildup around the exterior vent opening
- A long or poorly configured vent run
- A disconnected or damaged section of ductwork
- A problem with the dryer itself
If your dryer still heats but your clothes aren’t drying efficiently, don’t automatically assume the appliance is failing. The vent system may be part of the problem.
Why Longer Drying Times Can Be a Safety Concern
This is the part we don’t want homeowners to overlook.
A dryer is designed to move hot, moist air out of the appliance and through the vent system. When that airflow is restricted, heat and moisture may not be exhausted as efficiently.
That can cause the dryer to work harder and contribute to excessive heat buildup.
A dryer not drying properly isn’t necessarily just an appliance-performance issue. It can be a warning sign that the dryer isn’t getting the airflow it needs.
That’s why we recommend paying attention when your normal drying cycle starts taking significantly longer. Your dryer may be telling you that something needs attention.
5 Signs Your Dryer Vent May Have an Airflow Problem
Longer drying times are one warning sign, but they’re not the only one. Watch for these changes:
- Clothes are still damp after a complete cycle.
If loads regularly need two or more cycles, restricted airflow could be a factor. - The dryer feels unusually hot.
Some warmth is normal, but excessive heat around the appliance deserves attention. - Your laundry room feels hotter or more humid.
If warm, moist air isn’t being exhausted properly, the room may become noticeably uncomfortable. - You notice an unusual burning smell.
Stop using the dryer and have it checked if you notice a smell that concerns you. - Drying times have gradually increased.
A dryer that takes noticeably longer than it used to may be showing an early sign of restricted airflow.
Does My Dryer Vent Need Cleaning?
It may—but it’s better not to guess.
A professional dryer vent inspection can help determine whether lint buildup, a blockage, damaged ductwork or another issue is affecting airflow.
Depending on what is found, professional dryer vent cleaning may be recommended to remove accumulated lint and debris from the vent system.
The goal isn’t simply to make the vent “look” clean. Proper cleaning is about removing buildup that may be restricting airflow and preventing the dryer from operating as efficiently as it should.
If cleaning doesn’t resolve the problem, an inspection can also help identify other issues that may need attention.
What Can Cause a Dryer Vent to Become Blocked?
It’s easy to picture lint as the only culprit, but dryer vent problems can develop in several ways.
For example:
- Lint can accumulate over time, particularly when the vent hasn’t been professionally cleaned.
- The duct can become kinked or crushed, reducing the space available for airflow.
- The exterior vent hood can become blocked by lint, debris or seasonal buildup.
- A disconnected or damaged duct can prevent exhaust from leaving the home properly.
- A long or poorly designed vent run can make it more difficult for air to move efficiently.
This is why simply cleaning the lint screen after each load, while important, doesn’t necessarily keep the entire vent system clear.
How to Prevent Dryer Vent Problems
You can’t prevent every dryer vent issue, but a few simple habits can help reduce the risk and help you spot problems earlier.
- Clean the lint filter after every load. This helps maintain airflow and reduces lint entering the vent.
- Pay attention to drying times. If a normal load suddenly takes much longer, don’t ignore the change.
- Keep the area around your dryer clear. Avoid storing clothing, boxes or other items around the appliance or vent connection.
- Check the exterior vent opening. Make sure it isn’t visibly blocked by lint, debris, snow or other obstructions.
- Have the vent professionally checked when needed. If drying times continue to increase despite regular lint-filter cleaning, there may be buildup or another airflow restriction deeper in the system.
A little attention can go a long way. Your dryer shouldn’t need multiple cycles to do a job it used to finish in one.
