The answer to 'dryer vent cleaning smells bad' is that a smelly dryer vent is typically caused by a buildup of lint, debris, or mold inside the vent. This can create unpleasant odors that get circulated back into your home. The symptoms may include a musty or burning smell coming from the dryer, reduced airflow, or increased drying times.
To address this issue, you'll want to clean the dryer vent thoroughly. This is generally a DIY task that most homeowners can handle, but it's important to take the proper safety precautions. For a simple vent cleaning, you can use a specialized vent brush or vacuum attachment to remove the lint and debris. However, if the vent is severely clogged or you suspect mold growth, it's best to call in a professional dryer vent cleaning service to ensure the job is done safely and effectively.
