Question: 1 / 400

What is one consequence of neglecting duct insulation?

Decreased air quality

Neglecting duct insulation can lead to decreased air quality as a significant consequence. Ducts that are not properly insulated can allow conditioned air to lose temperature, which may also allow for the infiltration of unconditioned air from attics or crawl spaces. This unconditioned air can contain pollutants and allergens, which can be drawn into the home's air supply. Consequently, this can result in poorer indoor air quality, as contaminants circulate more freely within the living space.

In homes where ducts are not insulated, thermal losses can also contribute to increased humidity levels and temperature fluctuations, further compromising the air quality. A well-insulated duct system, on the other hand, helps maintain temperature and pressure, supports better filtration, and maintains a more consistent indoor environment, which contributes positively to air quality.
