Does Duct Seal Go Bad? An Expert's Guide to Air Duct Sealing

The lifespan of a duct seal is typically 10 years, but many homeowners don't realize that an air duct system can degrade over time. Hot air, rodents, moisture, and other environmental factors can all cause fraying in the air ducts. To reduce air conditioning and heating costs, as well as stay cooler in summer, it's important to check and seal the air duct system. Certified Aeroseal air duct technicians, such as DuctMedic, are qualified to direct a program created by the Environmental Protection Agency (EPA) called “Duct Investor”.

This program takes a full list of variables and provides the owner with the best available estimate of what they should achieve in terms of cost savings. The purpose of an air duct is to carry hot or cold air from the air conditioner or central heater to every room in the house. I have had success sealing ducts in houses with flat roofs, using long posts, perseverance and liters of putty. Aeroseal seals air leaks in air ducts to help improve the air supply capacity of heating, ventilation, and air conditioning (HVAC) equipment.

Your local home service or HVAC contractor can tell you if the ducts need to be cleaned before sealing them. In most homes, only 10% of ducts can be sealed by hand, while more than 95% of ducts can be sealed with the AeroSeal process. It is even more important to seal air ducts when they are located in unconditioned areas, such as attics, basements, mezzanines, roofs, and other places. The sealing particles go to the leak points (joints, joints, voids) of the duct network, adhere to the edge of the opening and begin to form a seal.

Air duct leaks not only waste energy but they also cause many other airflow problems in homes and buildings. In many situations, the air duct system can reduce the heating or cooling capacity of a system to less than 50 percent of its efficiency. The Aeroseal air duct sealing system can reduce the amount of leaks by up to 90%, reducing dust and other indoor air pollutants from your home air conditioner. It uses synthetic nanoparticles which are tiny particles that are specially manufactured to fit together and create a way to prevent air from escaping, in order to make the ducts as airtight as possible.

To ensure your home's air duct system is functioning properly and efficiently for years to come, it's important to have it inspected regularly by a certified technician. They will be able to identify any potential issues with your system and recommend any necessary repairs or replacements. Additionally, they can provide advice on how best to maintain your system so that it continues to work optimally for years to come. Air duct sealing is an important part of keeping your home comfortable and energy efficient.

By regularly inspecting your system and having it sealed when necessary, you can save money on energy costs while also improving your home's indoor air quality. With Aeroseal's advanced technology and certified technicians like DuctMedic on hand, you can rest assured that your home's air duct system will remain in top condition.
