The answer to 'air duct cleaning discolored' is that discolored air ducts can be caused by a buildup of dust, debris, and even mold. This can lead to poor indoor air quality and potential health issues. The solution is to have your air ducts professionally cleaned on a regular basis, typically every 3-5 years.
Discolored air ducts are a common problem that can occur over time as dust, pet dander, and other airborne particles accumulate in the ductwork. This can cause the ducts to appear dirty or stained, which can then circulate throughout your home. Professional air duct cleaning can remove this buildup and restore the appearance of your ducts.
