HVAC ductwork is a system of metal or synthetic channels or pipes that transport heated or cooled air throughout your home. In a forced air system, the warm or cool air is blown into the AC ductwork/furnace ductwork at the location of the furnace or air handler blower fan. 

The heated or cooled air exits the ductwork system at the supply registers or air vents, which may be floor vents or baseboard vents. Ductwork is located throughout the home, in the basement or crawlspace, and behind the walls. You may see exposed ductwork in the basement or crawlspace.

Signs of Leaky Ductwork

You may have leaky ductwork if:

  • You can see a visible gap or feel air escaping from exposed cutwork.
  • You have uneven heating and cooling. 
  • Air vents are dusty.
  • You have excessive dust in the home.
  • You have high energy bills even with an efficient system.

It’s important to note that other HVAC system issues can cause some of these problems, so it’s a good idea to consult with an HVAC professional to test the airflow in your home if you suspect you have leaky ducts.

Sealing ductwork that is exposed is an easy fix. Locating and fixing leaky ductwork that is hidden in the walls is a little trickier, and you will need an HVAC professional.

Air Duct Cleaning

The jury is still out on the usefulness of ductwork cleaning. If you have mold in your ductwork or an infestation of mice or pests, it is definitely worthwhile. Air conditioning ductwork with visible clogs should also be cleaned. 

If you’re considering hiring someone to clean your ductwork, do your homework first. Read this article from the Environmental Protection Agency (EPA) for guidance.
