Which component can be adversely affected by poorly maintained ducts?

Poorly maintained ducts can lead to a decline in air quality within a space. When ductwork is not properly cleaned and maintained, dust, pollutants, and allergens can accumulate inside the ducts and be circulated throughout the environment. This can create issues such as poor indoor air quality, increased allergens, and potential health problems for occupants.

While aspects like heating capacity, system aesthetics, and visual appeal may be impacted in a broader sense, the most immediate and critical concern with poorly maintained ducts is how they affect the air that people breathe. Keeping ducts well-maintained is essential for ensuring that the air quality remains high and safe, thus promoting a healthier indoor environment.
