What is a potential consequence of neglecting duct cleaning?

Improved air quality Increased energy efficiency Higher likelihood of mold growth Decreased system lifespan

Correct Answer:

Higher likelihood of mold growth

Explanation:

Neglecting duct cleaning can lead to a higher likelihood of mold growth within the HVAC system. When dust, dirt, and moisture accumulate in the ducts, they create an ideal environment for mold spores to settle and proliferate. This is particularly concerning because mold can not only harm the indoor air quality but can also pose health risks to inhabitants, especially those with respiratory conditions or allergies. In addition, the presence of mold in the ductwork can lead to complications in air circulation and can cause musty odors. Therefore, regular duct cleaning is vital in preventing mold growth, ensuring a healthy living environment, and maintaining HVAC efficiency.
