Aeroseal Duct Sealing Process To Save Energy Dollars

Aeroseal Duct Sealing Process…In recent years, the quest for saving energy dollars has focused on the air distribution system within the home, the ductwork in your home. Your ductwork carries the warm and cool air to the rooms. Traditionally these ducts have been seal with tape and clamps. Over 90% of existing buildings in North America have air duct systems that contain small holes and cracks that increase heating and cooling costs. These leaks result in higher energy costs as more air, hot or cool, is needed to reach the desired temperature. These leaks are hidden behind your sheetrock walls. They reduce the effectiveness of your high efficiency furnace.

Aeroseal Duct Sealing Process–A New Technology

Aeroseal Duct Sealing ProcessA new technology, Aeroseal, now allows us to measure and fix the duct leakage in your home by sealing the leaks from within the duct work. A computer test will tell exactly how much air is being lost in the duct work. Many people are surprised to learn their homes typically leak 30% to 40% or more of their air through air duct leaks.

With the Aeroseal process, we send polymer particles under pressure throughout your air duct system. These polymer particles to stick first to the edges of a leak, then to each other until the leak is closed. No particles are stuck to the inside of the duct work, only the holes and leaks. This process is perfectly safe. The process has tested to last over 10 years without failure.

What are the Results of the Aeroseal Ductsealing Process?

The Aeroseal air duct sealing system can reduce the amount of leakage by as much as 90%. A series of government reports have shown that air duct sealing can lead to up to $850 in energy savings per year. With the duct work leaks plugged, your system uses less energy to produce your desired temperature in all the rooms.
