Does Cleaning Your Ducts Really Make a Difference?

Because they’re deep in your walls, floors and/or ceilings, most homeowners don’t think a lot about air ducts. And when you do, what should be done about cleaning them — if anything? The recommendations are never one size fits all. There are many factors to consider, so we encourage you to consult the heating and cooling professionals at MTB before taking action. 

Of course, there are a few obvious signs your ductwork should be inspected, when you see evidence that:

  • Your ducts are inhabited by vermin
  • Your ducts have become clogged with dust or debris
  • Your ducts show signs of mildew or moisture buildup

According to  the EPA, research shows that cleaning components such as your cooling coils, fans and heat exchangers can help improve your HVAC system’s efficiency, but cleaning your ducts doesn’t have the same evidence to back it up. While air ducts do get dirty over time, cleaning them is not a requirement. 

However, if your home has a fuel-burning furnace, stove or fireplace, you should consult an MTB professional to inspect and service your ducts during the colder months. This to guard your home against the most extreme result of clogged or inefficient ductwork, which can occur in rare circumstances: carbon monoxide poisoning.
