How often should ductwork be inspected for maintenance?

Regular inspection of ductwork is crucial for maintaining HVAC efficiency and indoor air quality. Inspecting ductwork at least once a year allows technicians to identify and address potential issues such as leaks, blockages, or any deterioration in the duct material. Seasonal changes can impact the functioning of HVAC systems, and annual inspections help ensure that any buildup of dust, dirt, or mold is managed before it can affect air quality or system performance.

Additionally, annual maintenance checks can help prolong the life of the HVAC system, improve energy efficiency, and reduce energy costs. While more frequent inspections may be beneficial in certain situations—such as in homes with pets or high dust levels—annual checks are generally considered the minimum standard in the industry to support optimal system operation and performance.
