Dryer vent cleaning is an essential part of your regular home maintenance, especially if you use your dryer regularly. A professional dryer cleaning will free your duct of built-up lint and debris, decreasing your chances of dryer fires and increasing your overall home safety.

Rescue My Roof has been helping homeowners navigate home improvements for over a decade. That’s why we want to ensure that you have the information you need when scheduling a dryer vents cleaning.

This article will cover the six benefits you get from dryer vent cleaning. Ultimately, you’ll know why this service comes highly recommended and should be included in your home maintenance routine.

Why Should You Clean Your Dryer Vents?

It is a common misconception that the dryer’s lint trap and vent are the same thing. In reality, these are two different parts of the dryer that serve different purposes. The lint trap is the mesh grid, usually accessed from the front of the dryer. When emptied regularly, the lint trap catches a good portion of lint from each laundry load. 

The dryer vent, on the other hand, is located on the back of the dryer. It is responsible for releasing the hot air from the dryer to the outside of your home. Any lint that is not caught in the lint trap is often pulled into the vent, clogging up your dryer vent and preventing it from working correctly. Even if you routinely empty your lint trap, lint and debris particles will continue to build up within the vent. 

When too much debris builds up within the dryer vent system, it may reach the dryer’s heating element. Lint is highly flammable and can catch on fire within minutes if this occurs. Blocked dryer vents are thus a leading cause of dryer and house fires.

Professional dryer vent cleaning not only ensures your dryer’s external airflow, but also helps prevent lint-based dryer fires from starting.

When Should You Clean Your Dryer Vents?

If you use your dryer regularly, the U.S. Fire Administration recommends that you clean your vents at least once a year. If you’ve never had a cleaning, or if it has been over a year, it’s time to schedule a professional cleaning service.

Additionally, if you rent, you should ask the landlords or homeowner if they have a record of yearly cleaning. Outside of yearly maintenance, the frequency of cleaning can increase depending on how often you use the dryer, as well as if you are experiencing any signs of significant lint build-up.

Large build-ups of lint can cause several problems with your dryer outside of increased fire risk, including longer dryer times, musty-smelling clothing, burning smells, and more. Unpleasant as they might be, these symptoms serve as signs, telling you when to clean your dryer vent outside of your yearly schedule.

The Top 6 Dryer Vent Cleaning Benefits

If you decide to get your dryer vents professionally cleaned, there may be many visible changes in your dryer’s performance. After getting serviced from a trusted professional, you might receive one or more of the following dryer vent cleaning benefits:

1. Faster Dryer Times

If you’re used to sending your clothes through multiple cycles to fully dry them, cleaning the dryer vent might help. If a vent is blocked, the humid air inside your machine has trouble escaping during a normal cycle. The lack of dryer vent airflow can make it harder for your wet clothing’s moisture to evaporate, making you run it several times to get your favorite garments completely dry.

A clear vent free of debris will allow your dryer to operate more efficiently, making drying cycles more effective. As a result, your dryer will not have to work as hard to dry your clothing. Your machine will be able to easily push hot air from the clothing chamber to the outside of your home, allowing your clothes to dry in less time or one complete cycle. 

2. Less Damage to Clothing

Along with shorter drying times, cleaning the dryer vent can also prevent damage to your clothing. The clearer your dryer vent is of lint, the faster and more effectively it will dry your clothes.

According to a study by the American Chemical Society, cotton fabrics suffer significant damage under high temperatures. If you cut the number of cycles required to dry your clothes in half, the damage done to your clothing should also decrease. In this way, clean dryer vents can help your clothes stay in good condition and extend the wear life of your wardrobe.

3. Lower Risk of Dryer Vent Fires

Clogged dryer vents are a major cause of home fires and dryers, as mentioned previously. According to the National Fire Protection Agency (the leading information and knowledge resource on fire, electrical, and related hazards), failure to clean lint, fiber, or dust from dryers accounted for one-third of all 2020 U.S. dryer fires. 

An annual dryer vent cleaning can greatly reduce your overall fire risk in addition to preserving the health of your dryer. A trusted, trained professional can reduce the lint accumulation in your dryer and, in turn, prevent that lint from catching on fire. By sticking to a dryer cleaning schedule, as well as paying attention to your dryer’s signs, you can keep your home and valuable belongings safer.

4. Longer Dryer Life

Professional dryer vent cleanings can also help extend the life of your dryer. Blockages in the system prevent proper dryer vent airflow and heat release in your machine. This added strain can increase the amount your dryer has to work to dry your clothing. Each new load of laundry placed in a blocked dryer can add to the machine’s pressure and increase the amount of lint in the system. 

Giving your dryer a professional cleaning and removing any built-up debris can ease the strain, allowing the machine to work at a higher capacity. With proper care, the less your dryer has to work to dry your clothing, the longer it should last in general.

5. Better Indoor Air Quality

Clogged dryer vents affect the way your dryer can release hot air to the outside of your home. If excessive lint prevents your dryer’s hot air from releasing into the outdoors, that air pushes back inside of your dryer. With nowhere else to go, that hot air may be released into your home, affecting your home temperature and overall indoor air quality. 

A professional dryer vent cleaning will reopen your vent and allow the air to exit successfully into the outside, keeping your indoor air clearer and at a lower temperature.

6. Lower Carbon Monoxide Risk

If you own a gas dryer, a lint-clogged vent can allow carbon monoxide to enter your living space. With no way to vent the fumes your dryer is producing, the air from your duct system may be released into your home, negatively impacting your indoor air quality and causing other symptoms to occur.

If you constantly smell a burning odor when running the dryer, stop use until you can get it looked at by a dryer vent cleaning professional. That scent could be a blocked vent with possible carbon monoxide leakage.

Keeping your dryer vent maintained and professionally cleaned will help lower your risk of carbon monoxide poisoning from your dryer. By making sure your vent is consistently clear of lint and debris, you can feel relieved knowing that you are better protecting your family from harmful gas and toxins.

Scheduling A Professional Cleaning

Like we mentioned before, and as the U.S. Fire Administration recommends, you should have your air duct cleaned by a professional at least once a year (more often if necessary). If you ignore lint buildup in your system, it could be extremely costly to your home, health, and family.
