While the need for both your central equipment and your air ducts may seem obvious, you need to realize that each component affects the performance of the other. Your ductwork facilitates delivery of hot or cool air to various portions of your home, making the integrity of the materials important for optimum comfort results. At the same time, the mechanical equipment can lead to conditions that contaminate the ducts, creating problems with indoor air quality and structural integrity.
This interdependence make both HVAC maintenance and air duct cleaning top priorities. Dirty coils and heat exchangers, for example, can lead to dirt and residue moving into the ducts. Poor humidity control in an air conditioning unit or heat pump can affect your relative humidity, exposing the interior of your ductwork to the potential for deterioration or development of mold. Periodic air duct cleaning allows you to limit the severity of such issues by dealing with smaller concerns before they become serious.
