Air Duct Sealing

Are the rooms in your home uncomfortably hot or cold? Are you dealing with excessive humidity or dust? Are you experiencing a musty odor? Are your energy bills going through the roof?

Air ducts by nature leak at every joint and seam. Before sealing, the average duct system has 20-30% leakage, resulting in hot and cold spots in your home as well as high utility bills.

Clean Air Columbia is excited to be able to offer air duct sealing, through the Aeroseal process, to our customers.

Aeroseal Duct Sealing

Leaking ducts allow air passing through them to escape, wasting large amounts of energy and increasing both electricity use and emission of pollutants. Let us improve your leaky air ducts with Aeroseal duct sealing. It’s more effective and convenient than conventional methods of duct sealing because it requires less time and seals a larger portion of a leakage area!

"Steve cleaned the air ducts in our home and also sealed them.

During our Aeroseal pretest, we found that, for every minute that our air conditioning or heat was running, the equivalent to over 500 basketballs full of air was escaping and not traveling where intended! This resulted in an extra warm upstairs during the warm/hot months. (Of course there are more technical terms than that "500+ basketballs full of air," but Steve described the leakage metrics in a way that I was better able to understand to help quantify how much waste we were looking at — A LOT!)

AFTER Steve sealed our air ducts, that 500+ number was lowered by 479 to somewhere in the 50's! Because we worked with the city on their free energy audit process, my husband and I were able to get a rebate for completing the air duct sealing process in our home. With the air duct sealing (in combination with some other energy-saving measures we took), we received over $1,000 in total rebates from the city and Ameren. Our energy bills are also expected to reduce by 22% over this next year!

Thank you, thank you, Steve, for cleaning the air in our home so that this allergy-ridden gal can breathe easy and for making our home more efficient so that we are able to save on monthly energy costs! And, thanks for making the process easy to understand and flexible to schedule!"

Benefits of Aeroseal Duct Sealing

A new study showed that sealing ducts located in conditioned space saved up to 16% of energy and improved overall home envelope leakage by 11%. Beyond that, there are several benefits to Aeroseal duct sealing for both residential and commercial properties. 


If your family is suffering from allergies or your home’s temperature is uncomfortable; Aeroseal duct sealing will help:

  • Even temperatures throughout your home
  • Increase energy savings
  • Improve air quality
  • Minimize musty odors and excessive dust


Investing in Aeroseal duct sealing for your commercial property resolves:

  • Inadequate airflow to certain zones of your building
  • High utility bills
  • Insufficient moisture management

Aeroseal Key Points:

  • Seals from inside/out to help improve Indoor Air Quality, Comfort, and reduce Energy bills.
  • Seals visible, invisible, and inaccessible joints.
  • Results verified and performance guaranteed for 10 years for residential applications.
  • The result of total system leakage from Aeroseal implementation averages between 5% – 10% cfm.
  • Flexible and Malleable
  • The average home can be sealed between 4-6 hours, including prep, sealing, and tear down.
  • American homes waste over $25 billion in energy every year due to leaking air ducts.
  • Studies have verified that heating and cooling contributes up to 50% of the utility cost in a typical home and numerous experiments and field studies by utilities and national laboratories have concluded that 30-50% of the air in a typical home leaks out before reaching the occupied space.
  • Leaky ducts also create a significant strain on our environment. American homes use almost 25% of the energy consumed in the United States and the average home produces twice the greenhouse gases as the average car.
  • Leaky ducts also contribute to home comfort issues (excessive humidity and hot and cold rooms).


Until the development of the Aeroseal duct sealing technology, there was no efficient method of sealing remote leaks in HVAC ducts.

“Leaky air ducts are responsible for a huge energy loss problem in America and having the Aeroseal solution made available for the first time to many homeowners is very exciting to see,” said Thomas Baker, building technology editor for the magazine. Space heating and cooling drive residential energy demand and utility costs — it accounts for 54 percent of a home’s energy consumption.
