The Dangers of a Clogged Dryer Vent

Dryers require care and maintenance to run safely and efficiently. When your unit is in use, lint from clothes and linens may escape and get into the dryer vent, where they stick to the vent walls. With time lint build-up can restrict or block the dryer vent to limit its performance and create hazards for your household.

If you suspect your dryer vent is clogged, an experienced HVAC technician from A-Z Air Duct Cleaning can help remove all the debris and clean the unit. Contact us to schedule a consultation.

What Happens When a Dryer Vent Is Blocked

Dryer vent cleaning is recommended annually and more often for large families and those with pets. The cost of servicing is minimal compared to the loss of property and even life that result from dirty units.

Here are four dangers to avoid with expert cleaning and maintenance of your dryer vents:

Vent Fires 

The lint and other debris that collects inside your dryer are very flammable. When substantial amounts build up inside the vent, it traps heat and ignites fires that spread quickly once ignition occurs. Having an HVAC licensed technician to clean your dryer vent protects your clothing from burning and keeps the entire house safe from devastating fire hazards.


When your dryer vent is full of lint and other debris, airflow is blocked entirely, resulting in the build-up of dangerous carbon monoxide in your living spaces. Carbon monoxide poisoning can lead to severe tissue damage or even death. The most effective way to deal with this hazard is to prevent it in the first place. Ensure your dryer vent is regularly cleaned and inspected by a professional.

Mold and Mildew Build-Up

Trapped heat and humidity from a dirty dryer create perfect mold and mildew build-up conditions. Mold spores in the air don’t only result in musty odors, but they also expose you and your family to serious health risks. Mold causes allergic symptoms like itching, difficulty breathing, headache, and coughing. The best way to prevent these hazards is to clean your dryer vent regularly.

High Utility Bills

Like your AC or furnace, your dryer requires adequate ventilation to function optimally. A clogged dryer vent traps excess heat into your home while preventing the dryer from drying your linen effectively. This forces the dryer to work extra hard to achieve desired results, translating to higher energy consumption and utility bills.

The Warning Signs of a Blocked Dryer Vent

If you suspect your dryer needs cleaning, here are a few signs to look for:

  • Burning smells
  • It takes longer to dry a load of laundry
  • Vent hood flap that can’t close properly

How Often Should You Clean a Dryer Vent?

The general rule is to have your dryer vent inspected and cleaned by a licensed technician at least once a year. However, if you use the dryer often, clean it regularly. Regular cleaning helps prevent hazards and extend the lifespan of your unit.

Although cleaning a dryer vent yourself is tempting, it is always recommended to hire a professional cleaner to do the work for you is always recommended. Dryers are complex units that require extensive knowledge and understanding of parts to maintain. A DIY project can damage crucial units and affect the dryer’s performance. Professionals leverage their expertise and top-notch tools to achieve the best results.
