How often should HVAC ductwork be inspected?

Inspecting HVAC ductwork at least every three to five years is optimal for several reasons. During this timeframe, dust, debris, and other contaminants can accumulate in the ducts, impacting air quality and system efficiency. Regular inspections help identify issues such as blockages or leaks that can reduce the system’s performance and increase energy consumption. Over time, these problems can lead to more significant repairs or system failures, resulting in higher costs and discomfort.

Additionally, a three to five-year interval strikes a balance between maintaining system efficiency and preventing unnecessary inspections. While more frequent inspections, like annually or monthly, could be beneficial in specific scenarios—such as homes with pets or allergies—this general recommendation provides a practical guideline for most HVAC systems under typical usage conditions. It ensures that systems remain in good working condition without the added burden of constant monitoring.
