Air ducts are an often forgotten about aspect of many people’s forced-air heating and cooling system. Because they are often hidden behind walls, ceilings, or in basements, it is so easy to forget what an important job they have. The air ducts in your forced-air heating and cooling system are like the lifeline of your home comfort system. Sealing the ducts in your home can help your system run more efficiently, and save you money.

Determine if Sealing is Needed

Up to twenty percent of the air that moves through your duct system in a typical home is lost due to leaks and other issues within the duct system. So how can you tell if your ducts are in need of sealing? Here are some clues that may mean your ducts need attention:

  • Your utility bills are higher than you’d expect
  • You have rooms that are too hot or too cold
  • You can see damaged flexible ductwork
  • Some of the rooms in your home always feel stuffy
  • Your ducts are located in the attic, garage, or a crawlspace.

Duct Sealing

Duct sealing can seem like a complicated task, as many air ducts are difficult to reach in order to seal them. If you decide to conquer the duct sealing on your own, following a few simple steps will improve your air ducts performance greatly.

  1. Seal air leaks with mastic sealant or metal tape anywhere you can access the ducts.
  2. Insulate all ducts that are accessible to you in attics or crawlspaces, or in the garage.
  3. Seal all connections at vents and registers where it meets the walls, floors and ceilings. This is a common place for air to leak.
  4. Replace any old duct tape with mastic sealant or metal tape. Never use duct tape as it is not long lasting and will allow the air to leak again in just a few years.
