Are Your Air Ducts Leaking?

In the average home about 20% of the air that moves through your ducts is lost due to leaks, holes and poor connections. Improperly sealed ductwork will cost you money and result in energy loss.

In the average home about 20% of the air that moves through your ducts is lost due to leaks, holes and poor connections. Improperly sealed ductwork will cost you money and result in energy loss.

What to look for

Over time, the seals in your duct system become worn. Ducts are constantly submitted to the harsh weather conditions in your attic. You want to have your ducts sealed if you are experiencing any of the following:

  • High utility bills – especially in the peak of summer and winter
  • Rooms that are difficult to heat or cool
  • Stuffy rooms that never feel comfortable
  • A dusty house – even a few days after being cleaned


Many homeowners blame their heating or cooling unit when experiencing these issues. However, leaking or improperly sealed air ducts are often the culprits. If you have access to your ducts, look for tangled or kinked flexible ductwork or dirty insulation around the air ducts, these are telltale signs of air leaks. You may need to contact a professional to accurately identify the problem area(s).

Benefits of sealing your air ducts

Many homeowners invest heavily in energy efficient cooling or heating units but neglect their air ducts. Properly sealing your air ducts will result in several benefits for you and your home.

Lower energy bills

When your air ducts are sealed, you will be losing less air through your ducts. This means more of that air will be going into your home and heating or cooling your rooms.

More comfortable room

Uncomfortable rooms that are too hot in the summer and too cold in the winter are often caused by leaking air ducts. Stopping any leaks in your air ducts will increase the comfort level of your home.

Improved indoor air quality

The EPA estimates that indoor air quality can be up to 100 times worse than outdoor air. Leaking air ducts can contribute to poor indoor air quality by letting pollutants in through your ducts.

Don’t forget to insulate

Your temperature-controlled air escapes your HVAC system through more than holes, gaps and poor connections in ductwork. Air ducts that are not insulated also create insufficient heating or cooling systems by allowing heat gain in the summer and heat loss in the winter.

Older homes may still have metal air ducts that are not insulated. You can easily and inexpensively increase the efficiency of your home by insulating these air ducts.
