Aeroseal Duct Sealing West Milford, NJ

We Fix and Seal Leaky Ducts

• The amount and percentage of air leaking from the ductwork and other air flow or ventilation problems.
• Inconsistent temperature variations throughout the home or building.
• Air flow levels for each room.
• Backdraft and combustion safety hazard potential for fireplaces, furnaces, and gas heater rooms and closets in residential homes.
• Manual repair needs of air duct system.

In an Aeroseal air duct diagnostic, a certified Aeroseal technician inspects and evaluates your central air duct system and recommends ways to maximize your savings and improve your home comfort or improve building efficiency and solve air flow / ventilation problems.

Major factors during inspections are construction practices, type of duct work, age of the home / building, hot or cold or stuffy rooms, Indoor Air Quality (IAQ) problems, high energy bills etc.

Aeroseal’s trained and certified technicians use computer-based tools and reports to gather information about duct leakage and register airflows.

To start the Aeroseal duct sealing process, all room, ceiling or floor registers are replaced with foam plugs.

A small access hole is cut into the supply or return air plenum and a temporary collar is attached. The air conditioning indoor coil, fan, and furnace are temporarily blocked with a foam plug to avoid the entrance of any sealing particles into this equipment.

Once the system is properly sealed, the patented injection machine is connected to the air duct system using a flexible plastic tube.

The exclusive Aeroseal duct sealing system injects adhesive particles into the air duct system. The particles travel through the air duct system seeking holes and cracks that are located throughout the ductwork. The adhesive duct sealing particles attach directly onto the edges of any hole and crack, effectively sealing it without coating the inside of the ductwork.

When the sealing process is completed, the results are verified and provided to the customer.

The air sealing system results are guaranteed for 10 years for residential homes.

After the Ductwork Sealing: Measuring the Duct Seal.

Once the Aeroseal air duct sealing is complete, the technician will again measure the duct system leakage.

A sealing certificate and a tightness certification are generated by the computer. The sealing certificate shows duct leakage amounts before and after sealing, as well a graph of the sealing process, plus overall heating or cooling capacity improvement. The tightness certification, affixed to your duct system, shows the tightness of the duct system after completion of the sealing process.

Aeroseal can reduce duct leakage by up to 90% and save a typical homeowner up to $1000 a year in energy costs and a typical building up to 30% of HVAC energy use.

While energy savings resulting from reducing leakage vary based on climate, utility rates, and your heating and cooling system, the other goals of even temperatures in all rooms, improved indoor air quality, and reduction of odors and fumes will be achieved regardless of those conditions. In commercial building applications, Aeroseal also solves air flow and ventilation issues in addition to energy savings.

The Aeroseal 6-step process takes very little time to bring you big savings and comfort:

• Wall registers are covered in order for air to escape only through the leaks
• Sealant in injected into the ducts for approximately 1 hour
• 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
• Ducts are sealed with only 1-2 oz. of the sealant material remaining in the ducts
• A computer-generated analysis summarizing your home’s or building’s amount of leakage is generated, providing verification of success of the process

Does your home or building experience:

• High Energy Bills?
• Constantly Running System?

Over 90% of existing buildings located throughout North America have air duct systems that contain small holes and cracks that reduce the level of comfort and increase heating and cooling costs.

Leaks are caused by a variety of factors including the age of the dwelling, type of construction, type of ductwork and local building codes.

Repairing and patching leaks in HVAC duct systems saves cooling, heating, and fan energy. In air-based systems, ducts deliver all of the heating and cooling to conditioned spaces. Any duct leakage translates into extra air that must be supplied so sufficient heating or cooling reaches the conditioned space. This not only increases effective heating and cooling loads, it also increases fan energy due to increased flow and/or run time. Sealing duct leaks reduces the amount of heated or cooled air the supply fan must handle to deliver the same amount of air to the conditioned space.

Basically:

• Preseal test to measure the leakage as a baseline for measuring progress.
• Block off the registers with foam or plastic.
• Inject an UL tested and approved aerosol into the duct system.
• Since the air has no place to go except out through the leaks (the registers are blocked), the sealant material is deposited precisely at the air duct holes or cracks where leakage occurs.
• A computer and sensors are used to measure and control the progress. The technology is patented from the University of California and the process is endorsed by the Environmental Protection Agency.
• Postseal test to measure improvements.
• Complete report and certificate printed on the spot to provide a record of improvements.
