How Often Should You Clean Your Dryer Vent?
While the majority of homeowners know to clean the lint collector after each use, many don’t realize that they need to clean the dryer vent. The lint filter will remove a considerable amount of lint, but very small fibers will pass through the dryer exhaust system with each cycle. This lint over time will accumulate in the dryer vent, which will cause the dryer to lose efficiency, to become hotter, and to decrease in airflow.
So, how often should dryer vent be cleaned? For most households, a dryer vent cleaning service is advisable at least once a year. Households that have more people or pets, or laundry often, however, may require cleaning twice a year to keep it safe and efficient.
Cleaning the dryer vent is not just a nice thing to do, it is crucial to safeguard your home, save on energy bills, and prolong the life of your dryer. Here, you will be able to see the suggested cleaning schedule, as well as the factors that will influence it and the indicators that it’s time for your dryer vent to be cleaned.
Why Cleaning Your Dryer Vent Is Important
Each time your dryer is used, warm and damp air circulates through the dryer exhaust vent and goes outside of your home. This air traps bits of lint as it flows through the vent and eventually it accumulates on the inside of the duct. These deposits grow in months of use, blocking air flow.
When your dryer vent is clogged, your dryer has to run longer to dry laundry. More drying cycles require more electrical or gas consumption, more stress on the heating element and motor, and may shorten the life of your appliance.
The negative airflow also creates an excess of heat which gets trapped in the dryer. This, along with buildup of lint, which is extremely flammable, creates a safety hazard that can be avoided. These obstructions can be prevented from causing serious issues if they can be cleaned out on a regular basis.
When to Clean Dryer Vent?
The typical home family can safely clean the dryer vent every 12 months. Annual maintenance is required to clear lint build-up, maintain adequate air flow, and keep the dryer running efficiently.
But on some houses this needs to be done more often.
Clean Every 6 Months If You:
- Do more than five loads of laundry each week.
- Have a large family.
- Use a heavy shedding dog or cat.
- Clean towels, blankets or pet bedding frequently.
- Have a long or complex dryer vent with multiple bends.
- See your dryer is longer drying clothes.
Heavily used laundry homes produce a great deal of lint that can cause blockages to occur much sooner than the average.
Consider Quarterly Inspections If:
Apartment buildings, hotel laundry, salons and commercial buildings may have dryers operating all day long. Dryer vents should be cleaned every 3–4 months in these environments and when airflow starts to be blocked by a lint build-up.
Things That Can Influence the Frequency of Dryer Vent Cleaning
Lint production varies between each house. There are a number of variables that will determine how quickly your dryer vent will clog.
1. Laundry Frequency
Lint builds up quicker in the venting system the more often your dryer is used. More frequent maintenance is generally required for a daily use as compared to a laundry use.
2. Pets
Pet hair can get stuck in clothes, blankets and towels. Some hair will still fall through the lint screen and the exhaust duct, leading to quicker clogs.
3. Vent Length and Design
Long dryer vents equipped with many elbows provide more litters of lint collection. The longer the vent runs the longer the house will need to be cleaned.
4. Vent Material
Older flexible foil or plastic ducts can gather more lint and aren’t as efficient at directing the air flow. Rigid metal ducts are more efficient at directing the airflow and collect less lint than older flexible foil or plastic ducts. Installing a rigid metal vent can help make the dryer more efficient and make it easier to maintain.
Recognizing the Warning Signs of a Dryer Vent in Need of Cleaning
Homeowners often do not realize that their dryer vent is clogged until it starts to cause issues in the dryer. These are typical warning signs to look out for:
- Two or more drying cycles are needed for clothes.
- Dryer is warmer than usual after drying.
- Clothes start to give off a burning odor when they are being dried.
- The laundry space can be hot and humid.
- There is little to no air flow from the outside vent.
- Too much lint gathers around dryer or vent opening.
- The vent flap on the outside doesn’t open completely when the machine is running.
- You notice your energy bill rises but there’s no apparent reason.
The symptoms can increase utility bills, appliance wear and tear, and costly repairs.
The Advantages of Having a Professional Dryer Vent Cleaning Service
Professional dryer vent cleaning will use specialized equipment to clean the vent system, including all the vents, which are not accessible to homeowners, and remove lint, dust and debris.
Regular maintenance offers a number of advantages:
- Faster drying times.
- Improved energy efficiency.
- Save by reducing utility bills each month.
- Reduced strain on your dryer.
- Improved ventilation system.
- Extended appliance lifespan.
- Improved home safety.
- More security.
Most homeowners are able to see a difference in their dryers right away after a professional cleaning.
Final Thoughts
When it comes to how often to clean the dryer vent, it depends on how often you use the dryer, but most people have a dryer vent cleaned at least once a year. Every six months may be warranted for households with pets, large families or frequent dryer use.
When the dryer’s performance starts to decline, energy costs, repair expenses and safety risks can all increase. Regular dryer vent cleaning is a great way to enhance the efficiency of your dryer and prevent potentially dangerous issues in your home.
When your clothes are taking longer than usual to dry or you’ve seen any of the signs that indicate that your dryer vent is restricting airflow, it’s time to schedule a dryer vent cleaning and inspection.
