It’s no secret, but a hidden problem in your home can cause some big problems when it comes to home comfort, health and energy efficiency. Duct leaks cost homeowners valuable energy and money when conditioned air leaks into attics, crawl spaces or into walls that communicate with the outside of the home. They can also allow dirty air from these spaces to move into the home. Duct sealing can solve these problems and provides real benefits for comfort, indoor air quality and energy savings. There are a number of different techniques that can be used when it comes to the sealing of ducts. The most effective of these methods is Aeroseal duct sealing.
Most traditional duct sealing processes rely on a painted on material that seals the outside of ducts to stop leakage. There are a few potential problems with this process. First, this only allows visible portions of ducts to be reached and sealed. Second, it could potentially leave room for error during application of the sealant.
Aeroseal, however, provides the most comprehensive coverage by sealing from the inside out. Aeroseal software allows a professional technician to accurately measure the duct leakage in the home. The process then puts air leaks under pressure and causes polymer particles to stick first to the edges of the leak, then to each other until the leak is filled. This process also addresses the issue of the inability to reach ducts hidden within walls, floors and ceilings. Since the process seals all leaks from the inside out and travels through the entire duct system of the home, no leak is missed even in hard or impossible to reach places.
During the Aeroseal process, sealant is injected into the ducts for approximately one hour depending on the size of the home and duct system. The sealant actively seeks out and fills leaks. Ducts are sealed with only 1-2 ounces of the non-toxic sealant material remaining in the ducts. Once the process is complete, a computer-generated analysis is performed by the HVAC professionals to confirm successful sealing of the entire duct system.
Duct sealing has many different benefits. Completely sealed ducts provide maximum comfort and indoor air quality in your home. Properly sealed ducts also have environmental benefits by reducing the amount of energy and fossil fuels used to heat homes.
Duct leaking is a significant problem for many homeowners and causes a great deal of wasted energy and money for homeowners, especially in our area of the country. Our tests show that most homes in the Puget Sound area have significant leaks in their duct system. If you want to ensure that you get the comfort you are paying for, have BelRed seal and insulate your duct system with Aeroseal.
