The answer to 'my air duct is filthy' is that a dirty air duct is a common problem for many homeowners. Over time, dust, debris, and even mold can build up in the ductwork, reducing air flow and indoor air quality. Common causes include lack of regular maintenance, pets, construction work, or simply living in a dusty environment.
Some common symptoms of a dirty air duct include reduced airflow, musty odors, and increased dust and allergens in the home. The good news is that this issue can often be resolved through professional air duct cleaning. However, if the problem is severe or you suspect mold growth, it's best to call in an HVAC specialist to properly inspect and clean the ducts.
