Aeroseal can reduce duct leakage by up to 90%, reduce your energy use by up to 30%, and save you up to $300 a year in energy costs. Aeroseal has also been shown to dramatically improve comfort and homeowner satisfaction with their heating and cooling systems.
The US Department of Energy (DOE) states that energy wasted from leaky residential ducts alone is equivalent to the energy burned by 13 million cars a year.
Rick Kallet - Homeowner, Sacramento. "Aeroseal really made a difference. In the winter I could heat up the downstairs a lot more quickly and in the summertime the upstairs would cool down more quickly."
Aeroseal Ductwork Breakthrough:
Aeroseal's aerosol ductwork sealing technology was invented and developed by the Energy Performance of Buildings Group at Lawrence Berkeley National Laboratory in 1994. This technology internally seals duct leaks in air distribution ducts by injecting a fog of aerosolized sealant particles into a pressurized duct system.
The key to the technology is to keep the particles suspended within the air stream without depositing on the duct surfaces until they reach the leaks, where they leave the air stream, deposit at the leak edges, and seal the leaks. Aerosol particles are directed toward and deposit at the ductwork leaks because:
- All supply and return grilles are temporarily sealed, so that all the airflow passes through the ductwork leaks;
- Small aerosol particles are kept suspended in the airflow by continuous air movement;
- As the air stream makes a sharp turn to exit through a leak, the particles collide with and adhere to the leak edges; and
- Using adhesive solid particles allows the built-up seal to span leaks as much as one inch across.
Advantages of Aerosol Ductwork Sealing
Aerosol ductwork sealing improves upon conventional air duct-leak sealing methods because it:
- Seals more of the leakage by getting to inaccessible leaks;
- Provides better working conditions so that workers do not have to spend a long time in the attic or crawl space to perform the sealing; and
- Is less time consuming to carry out and is less costly to homeowners.
We Find Airflow Problems and Leaky Ducts
The Aeroseal air duct diagnostic system tests specifically find:
- The amount and percentage of air leaking from the ductwork.
- Inconsistent temperature variations throughout the home.
- Air flow levels for each room.
- Proper sizing of return air grilles.
- Backdraft and combustion safety hazard potential for fireplaces, furnaces, and gas heater rooms and closets.
- Manual repair needs of air duct system.
In an Aeroseal air duct diagnostic, a certified Aeroseal technician evaluates your central air duct system and recommends ways to maximize your savings and improve your home comfort.
Aeroseal's trained and certified technicians use computer-based tools and reports to gather information about duct leakage, register temperatures and register airflows.
The diagnostic process includes the use of a high quality flow hood and laser sighted infrared non-contact thermometer. These tools assist the contractor in performing a rapid high quality assessment regarding the condition of an air duct system. An air duct system analysis can be completed in approximately 2 hours.
Diagnostic results are documented in a printed report that is printed on-the-spot and given to a home owner.
The U.S. Department of Energy and the Electric Power Research Institute determined ... 25% to 40% of the heating and cooling energy put out by heating, ventilating and air conditioning systems ... is lost through the duct system.
Jeff Warther - Homeowner, Indianapolis. "When Aeroseal first came out, we did a diagnostic on the house and found out that the duct leakage was over 25% which was a real big surprise in a new home. Once the process was complete, the technician showed me the before and after numbers showing a reduction in leakage of over 80%."
