Ductwork is a critical part of HVAC systems that is often ignored. Since most of your home’s network of ducts is hidden from view, it’s easy to take it for granted for months or even years. While ductwork is generally reliable, over time the performance of ducts can deteriorate as individual seals become loose. A simple ductwork inspection can reveal issues that need to be corrected.

Why Tight Ductwork is Critical

If your ductwork has poor seals or leaks, it allows air to pass between the inside and outside of the ducts, which has significant consequences:

  • Air quality. Leaks can allow dirty or stale air to enter the ductwork where the ducts run through unconditioned areas such as the attic and crawl space. This air is typically unfiltered and can contain dust, mold and various other micro-organisms. These particles lower the air quality of the air circulated in your home that you breathe.
  • Efficiency. Some of the cold or warm air your HVAC system generates won’t reach its destination if its leaking from faulty ducts. In order to make up for this lost air, your A/C or furnace has to work harder and longer. This causes extra wear and tear and raises your energy bills.
Inspecting Ductwork for Issues

In order to get a handle on the state of your ductwork, inspect the ducts where they’re accessible. Typically, there will be some exposed ductwork in crawlspaces or the attic that you can have a look at. While you won’t get a complete picture, it will give you an indication of the overall health of your ductwork.

If you want a comprehensive inspection, the best option is to call in an HVAC professional. A technician will have the experience, tools and knowledge to evaluate the condition of your ducts and identify any problems.

Most small leaks can be fixed with mastic sealant or metal-backed tape. Note that regular duct tape won’t survive the temperature variations that ducts commonly experience. If your ducts are seriously compromised, the ductwork may have to be replaced.
