As a result, the air ducts get contaminated over time while the home indoor air quality tends to deteriorate.

1. Dust from Various Sources
The problem with dust can be particularly pressing when one of several factors is present.

Holes, improperly set connections and air leaks let extra air in and dust along with it. In this case, the dust usually comes from drywall, paint and other structural materials. If the HVAC registers have been left open during construction and repair works, the contamination can be particularly high.
Air duct cleaning is the main solution to this problem along with filter replacement. The sooner it is done, the better. Seal repair is also essential. Even the smallest holes and crevices must be sealed tightly.
2. Pollen Whose Peak Is in Spring
As one of the most powerful allergens, pollen can easily make people sneeze and cough for weeks.
