05_09_13Air duct cleaning is an effective way to improve the air quality in your Dallas area home. All of the air that heats or cools your living spaces travels through the air ducts, which means that keeping this air distribution network clean and free of contaminants can reduce the effects of allergies, asthma and other respiratory conditions.

Material such as dust, dirt, lint, hair, fibers, insect or rodent nests, mold and other contaminants can accumulate in your ductwork. When your HVAC system is first turned on for the season, these particulates can be dislodged by airflow and sent into your home’s interior. Large accumulations can continue to contaminate your air over a long period. Professional air duct cleaning will remove any built-up contaminants or sources of particulates.


Air duct cleaning has not been shown to prevent any particular health conditions, according to the U.S. Environmental Protection Agency. However, the EPA recommends duct cleaning under three specific conditions:

  1. Mold is growing inside the ductwork or on your HVAC equipment and is visible on duct surfaces or system components.
  2. Ducts are inhabited by insects or small animals that have left behind nests, fur, feces or other contaminants.
  3. Ducts are fully or partially blocked by debris, which will restrict airflow and significantly reduce HVAC system effectiveness and efficiency. A sign of this might be debris blowing out of registers.

If your ducts are emitting large amounts of particulates, are producing unusual odors or seem to be clogged, a duct cleaning may be a wise choice. Air duct cleaning also lets an HVAC expert examine your duct system from end to end. This provides a chance to find any ductwork problems such as broken seals, loose connections, or detached sections that need repair.


Choose your duct cleaning contractor carefully and beware of overly positive claims about the benefits of duct cleaning. Check contractor references and qualifications and make sure the company will correct any damage to the ductwork the cleaning process may cause.
