An air duct sealing system is used to close any holes, leaks, or poorly linked ducts. A duct sealing system involves identifying inefficiency in your system and making necessary steps to improve it. You can do it by yourself or find an expert to do it for you. During the process, the system will seal or cover the ducts with a rubber or non-toxic material.
How much is it?
- There are different processes and materials used with air duct sealing. An aerosol air duct sealing system, for example, will not cost you much.

What is going to be included?
- Before the procedure begins, a contractor will set up test equipment to depressurize the house to find any holes or leaks. During this process, the registers will be blocked with foam, forcing the air to go out through the leaks. Special technology and sensors are used to measure and control the process. When the leaks are located, the joints in the ductwork will be sealed using a special paste that is non-toxic and effective. After these leaks are plugged, the contractor should run the test again to measure the leakage.
- The benefit of sealing your ducts will be energy saving efficient, give you pronounced comfort in your house and better air quality.

Tips to know:
- There are some things that you can do on your own to help with air duct sealing. You can inspect and repair any of the ductwork that you can see in attics, garages, basements, etc. You can also check the connections around the vents to make sure they are sealed since this is one of the most common problem areas. However, it is not recommended that you use duct tape to repair anything; it does not last as long and is not as efficient.
It is said that about 20% of the cool or warm air in the air ducts is lost due to leaks within the system. In order to determine whether or not this is a problem in your home, check the following things:
- If you compare your summer cooling bills and winter heating bills with those of your neighbors (with similar size homes) and yours are much higher, chances are you have leaks in your duct work.
- There may be some rooms in your home that are harder to cool or warm, usually those that are further away from the furnace.
- If the rooms in your home are beginning to feel stuffy and stale, it may be due to the air not being circulated as well since the ducts are leaking air.
- Observing the system can give you a lot of clues. If there are any kinks in any of the duct work or if there are any visible or audible air leaks, chances are good that this is true in the rest of the home as well.
How can I save money?
- An air duct sealing system can save a lot. A series of reports from the government have shown energy savings of up to $850 per year after getting air ducts sealed. Homeowners have been able to save up to 40% of their energy bills, and although the exact energy saving is difficult to estimate, most homeowners, regardless of the climate, have been able to save as much as 40 percent.
- Some states such as Oregon offer tax credits to homeowners who take advantage of this service. Check with your local government or look online to see if you can take advantage of any credits.
