How to Deep Clean Your Dryer: Simple Annual Maintenance for Toronto Homeowners
Last Updated: January 2025
A dependable dryer keeps your laundry routine moving smoothly, but even well-maintained units need a yearly deep clean. Most Toronto and GTA homeowners clear the lint trap regularly, but a full annual cleaning is essential for safe airflow, shorter drying times, and preventing wear on internal parts. This guide walks you through the steps safely and easily.
Deep clean your dryer once a year to prevent overheating, reduce fire risk, and improve drying performance. Vacuum the lint trap housing, clean underneath and behind the dryer, clear the exhaust duct, and inspect the exterior vent hood for proper airflow. Always unplug the dryer before cleaning. If drying times remain long or airflow seems weak, schedule professional dryer repair with ARS Installation and Repair Inc.
Annual Dryer Cleaning Helps Prevent Overheating and Improve Efficiency
Lint, dust, and debris naturally accumulate inside your dryer and venting system. When airflow becomes restricted, the dryer has to work harder and operate at higher temperatures, which can lead to:
- Longer drying cycles due to weak airflow
- Higher energy use and increased utility costs
- Overheating risks caused by trapped heat
- Premature wear on the motor, belt, and heating element

Why Deep Cleaning Your Dryer Matters
Your dryer relies on steady airflow to remove heat and moisture from the drum. When lint collects inside the lint trap housing, under the dryer, or inside the exhaust duct, the entire system becomes strained. A yearly cleaning reduces fire risk, protects essential components, and keeps your appliance working efficiently—especially in busy Toronto households with frequent laundry cycles.
How to Deep Clean Your Dryer (Step-by-Step)
Before you begin, always unplug the dryer or turn off the breaker. These steps take only a few minutes and provide significant benefits.
1. Deep Clean the Lint Trap Housing
Removing surface lint with your hands helps, but deeper cleaning is more effective. Use a vacuum cleaner with a thin nozzle to remove lint and dust from inside the trap housing. A lint brush works as a backup option.
Hidden lint is a common cause of dryers not heating properly.
2. Vacuum Around and Underneath the Dryer
Pull the dryer forward several inches and vacuum the floor beneath and behind it. Dust and lint accumulate quickly in these areas and can be pulled into the appliance’s air intake. Wipe down the nearby wall and surrounding surfaces while you’re at it.
3. Clean the Exhaust Duct
The exhaust duct is crucial for releasing hot, moist air. When it becomes clogged, your dryer overheats and drying times increase. Disconnect the duct carefully and use a vacuum nozzle to remove lint inside the line.
If airflow still feels weak, consider booking professional dryer vent cleaning, especially for long or multi-bend ducts.
4. Inspect the Exterior Exhaust Hood
Go outside while the dryer is running a load and check the exterior vent hood. Warm air should blow out strongly, and the flaps should move freely. If the hood is blocked by lint, dirt, or debris, unplug the dryer and clean the exterior vent thoroughly.

FAQ: Dryer Deep Cleaning and Maintenance
How often should you deep clean your dryer?
At least once per year. Households with heavy laundry loads may need more frequent cleaning.
What parts of the dryer should be cleaned?
The lint trap housing, exhaust duct, exterior vent hood, and the area beneath and behind the dryer.
Can a clogged vent make the dryer overheat?
Yes. Blocked vents cause heat to build up inside the dryer, which can create a burning smell or even pose a fire risk.
Why does my dryer take too long to dry?
Restricted airflow from lint buildup or a blocked exhaust duct is the most common cause.
Should I clean the vent myself or hire a professional?
Short vents can be cleaned at home, but long or hard-to-access vent lines are safer and more effective when cleaned professionally.
