Airflow Obstructions Can Really Impact System Efficiency – Common Issues Pros See

Since your home’s ductwork is largely out of sight, it’s usually out of mind. So when a room isn’t cooling down or heating up as it should, it’s easy to jump to the conclusion that your air conditioner or furnace is to blame. Often times, however, the culprit is ductwork obstructions.

This finding can throw many homeowners for a loop. They often underestimate how some common airflow obstructions can have a profound effect on their system’s efficiency.

Here are some of the more common obstructions we see:

  • Stuck or partially closed fire damper and/or zone dampers.
  • An air filter that’s been drawn into the ductwork. In addition to blocking airflow, the filter also runs the risk of starting a fire if it’s drawn into the blower assembly fan.
  • Dirt on the blades of the blower fan. Here too, it’s easy to dismiss how the buildup of dirt, dust and grime can pose such a risk to the smooth operation of an HVAC system. This is one reason spring and fall tune-ups are so important. Cleaning the components is a big part of the job and will alleviate this worry.
  • Collapsed, crushed or otherwise damaged sections of ductwork. Sometimes this damage is visible from the exterior of the duct, and other times it can require an internal investigation.
  • Loose or collapsed insulation, which not only obstructs airflow, but also leads to greater energy loss.
  • Leaks in the ductwork or at the connections, which also lead to energy loss.
  • Furniture that’s improperly placed right on top of return air intakes. This is the easiest to fix and can be done by the homeowner.
