Why Is My Dryer Taking Longer to Dry? Common Causes for Airdrie Homeowners

If a load that used to dry in one cycle now needs two, it is worth paying attention. A restricted dryer vent is one possible cause, but it is not the only one. The load, lint screen, washer, vent route, and dryer itself can all affect drying time. Here is a practical way to narrow it down without assuming you need a repair or a cleaning.

What Does the Dryer Vent Have to Do With Drying Time?

A dryer moves warm, moist air out of the drum and through a duct to the exterior of your home. If that air cannot leave freely, moisture may stay with the clothes longer. Lint buildup, a crushed connection behind the dryer, or a stuck exterior vent hood can all restrict airflow. Natural Resources Canada recommends regular vent cleaning to maintain airflow and reduce strain on the motor.

Natural Resources Canada also recommends cleaning the lint trap after every load and avoiding overfilling the dryer. Both are sensible first checks before assuming the duct is blocked.

Five Common Reasons Clothes Take Longer to Dry

1. The load is too large or has mixed fabrics. A tightly packed drum leaves less room for clothes and air to move. Heavy towels and jeans can also remain damp after lighter items are dry. Try a normal-sized load of similar fabrics and see whether the result changes.

2. The lint screen needs attention. Empty the lint screen after every load. If you use dryer sheets, residue can sometimes form on the screen even when visible lint has been removed. Follow your dryer manufacturer's directions for cleaning the screen itself.

3. The vent or exterior opening is restricted. Lint can collect beyond the screen, including in the duct and at the outside hood. The flexible connection behind the dryer can also become crushed or kinked. These problems may reduce airflow and lead to repeated cycles.

4. Clothes are entering the dryer unusually wet. If your washer is not spinning water out as it normally does, the dryer has more moisture to remove. Check whether the clothes feel noticeably wetter at the end of the wash cycle than they used to.

5. The dryer has an appliance problem. A heating, sensor, or other mechanical issue can also cause poor drying. Vent cleaning helps when airflow is the problem; it does not repair the dryer.

What Can You Check Yourself?

Start with the simplest comparisons. Clean the lint screen, avoid overloading the drum, and notice whether the problem happens with every load or mainly with heavy items. If laundry is coming out of the washer soaking wet, check the washer's spin performance too.

If your exterior vent is safely reachable from ground level, look at it while the dryer runs. The flap should open and air should be coming out. Notice any lint collecting around the hood or anything visibly blocking it. Turn the dryer off before removing loose debris from around an accessible opening. Do not put tools into a running vent or climb onto a roof to inspect one.

A quick look outside cannot prove the full vent is clear. If drying times remain long, the outside airflow seems weak, or the vent has not been cleaned in a long time, the system deserves a closer look.

When Does Professional Vent Cleaning Make Sense?

Consider a vent cleaning if ordinary loads consistently need a second cycle, airflow at the exterior seems weak, you notice lint around the outside hood, or you do not know when the vent was last cleaned. Roughly annual cleaning is a useful starting point for many households, with the right interval depending on use and vent layout.

Our guide to how often you should clean a dryer vent explains when a home might need attention sooner.

At AirdrieDVC, we focus on preventative airflow cleaning. We clean the vent from the dryer side toward the exterior, remove lint from the dryer connection and accessible lint trap area, and check airflow before and after. We also inspect the exterior hood when it is safely accessible. You can see the steps on our

A clean vent can help when buildup was restricting airflow, but we cannot promise that vent cleaning will fix every slow-drying dryer. If airflow is clear and the problem continues, an appliance technician may be the better next call.

When Should You Stop Using the Dryer?

If you notice smoke, visible scorching, or a burning smell, stop using the dryer and have the cause checked before running another load. If there is smoke or an active fire, leave the home and call 911. Routine cleaning is not a substitute for addressing an immediate safety problem.
