Duct Sealing from Aeroseal®

Big savings, big comfort—we can seal your ducts from the inside

DuctWorks Heating & Air Conditioning | AerosealA recent study by McKinsey & Company, highlighted in The New York Times, cited the potential for homeowners to save on energy costs through relatively simple home improvements. The top improvement you could make for putting more money in your pocket? Sealing leaky ducts in your home.
How do you know if your ductwork is leaking? Signs include uneven room temperature, increasing energy bills, unpleasant indoor odors, accumulated dust on furniture, and high humidity.
The heating and cooling system in your home was designed to work best with ductwork that doesn’t leak. Reducing duct leakage can reduce your energy costs by up to 30 percent, while increasing the efficiency of your system. With duct sealing, you can also:
  • Increase your comfort by reducing hot and cold spots in your home
  • Breathe easier by improving the air quality of your home and reducing dust, allergens, and pollutants that enter your living spaces
  • Extend the life of your heating equipment
  • Protect the environment by reducing fossil fuel emissions
  • Stop any safety issues related to backdraft of appliance fumes, auto exhaust, or radon gases being released in your home
It’s possible to seal your ducts with a revolutionary technology called Aeroseal®, now available through DuctWorks Heating & Air Conditioning. Best of all, your ducts do not need to be cleaned before we begin aerosealing. The environmentally friendly process is clean, safe, and guaranteed for 10 years. And your energy savings, comfort, and healthier air will be enhanced immediately!

Award-winning Aeroseal technology

A gold medal winner of the 2016 AHR Expo Innovation Awards competition in the ventilation category, patented Aeroseal technology tackles leaks in your ductwork from the inside out and can be completed within one business day. Aeroseal software allows our technician to accurately measure the leakage in your home—before, during, and after the sealing process so you know it’s working.

  1. We plug your wall registers in order for air to escape through ducts to “discover” where the leaks are.
  2. Next, we inject sealant into the ducts for approximately one hour.
  3. Small aerosol particles are kept suspended in the airflow by continuous air movement.
  4. As the air stream makes a sharp turn to exit through a leak, the particles collide with and adhere to the leak edges, building up until the holes are closed.
  5. A computer-generated analysis summarizing the amount of leakage in your home is produced, providing verification of the success of the process.
