Ideally, duct seals should last as long as the rest of the duct system, but they are often seen to fail within a few years. Aeroseal has a 10-year warranty and has been tested for 40 years for strength in residential applications. Many factors determine how long an air duct sealer lasts, such as the age of the air conditioning system, the climate in which the building is located, the efficiency of the appliances that depend on the air conditioning system, the frequency with which the filters are changed and the maintenance of the rest of the system. When it comes to sealing ducts, there are a few different techniques and materials that can be used depending on the location and severity of the leak.
It can be difficult to access the entire duct system and leaks can be so small that it would be nearly impossible to see them with the naked eye. Diagnostic measurement provides a scientifically valid means of understanding the performance of your air duct system. Sealing your ducts is one of the best home improvement projects you can do from an energy standpoint. Filterbuy LOCAL offers thorough, expert and detailed air duct cleaning to help you know that your ducts are working properly. While you may be very skilled with a caulking gun, you will have trouble accessing your entire duct system and will lack the knowledge derived from years of experience. The cost of sealing air ducts will depend on the size and age of your system, the state of maintenance, the climate in your area, and the time since you last cleaned and sealed your ducts.
There is also an air duct sealer that can be sprayed onto the inside of the duct to seal it from the inside. Leaky return air ducts absorb dust and other contaminants from indoor air and send them to the central heating and cooling system. The inspection detects any obvious breaks in the ducts and, as an initial step in the sealing process, the Aeroseal system will determine the exact amount of leaks in the duct system. Most customers find that once their ducts are sealed using the Aeroseal process, they don't need to be cleaned again for some time. It's important to have professionally sealed ducts so you can rest easy knowing you won't suffer from a poorly sealed system.
With proper maintenance and care, your air duct seals should last as long as your entire air conditioning system.
