Air duct cleaning is essential. Make sure the inside of your ductwork is clean. Many homeowners replace the air handlers but leave the ductwork in place. Over time, dust, dirt, and mold accumulate in the ducts. These contaminants become entrained in the airflow and are distributed into the room air when the unit is on. Disconnect a supply branch from the main supply trunk immediately downstream from the air handler, and evaluate levels of dust, dirt, and mold inside your the trunk. Using a HEPA filter vacuum cleaner, vacuum the interior surfaces of the trunk to reduced levels of dust/dirt, and mold.
