As an expert in the field of HVAC systems, I have been asked numerous times about the effectiveness of Aeroseal in sealing ducts. Created by the company of the same name, Aeroseal is an aerosol-based technology that promises to fill and seal small and medium-sized leaks in household ducts from the inside out. But does it actually work? In this article, I will share my knowledge and experience with Aeroseal to help you understand its capabilities and limitations. First and foremost, let's clarify one thing - the ten-year warranty offered by Aeroseal is for the sealant itself, not the lifespan of the ducts. The sealant used by Aeroseal has been tested by an independent laboratory and has been found to have an extremely low VOC concentration during the sealing process.
This means that it is safe for both homeowners and contractors to use. Now, let's address the main question - can Aeroseal be used to seal sheet heating, ventilation and air conditioning ducts enclosed in concrete slabs? The answer is yes, but under certain conditions. The process involves injecting the sealant into the ducts and using air pressure to distribute it evenly throughout the system. This method has been proven to effectively seal leaks and improve airflow efficiency. One of the biggest advantages of using Aeroseal is its ability to improve air quality. By sealing leaks in the ducts, it prevents dust and other pollutants from entering your home.
This not only creates a healthier living environment but also reduces the amount of dusting and cleaning needed in your home. Another benefit of Aeroseal is its long-lasting results. While the warranty covers 10 years, the sealant itself has been known to last for decades. This means that you can enjoy the benefits of improved air quality and energy efficiency for many years to come. However, it is important to note that Aeroseal is not a solution for all duct problems. It is most effective in sealing small and medium-sized leaks, but larger or more complex leaks may require additional repairs.
It is always best to consult with a professional HVAC contractor to determine the best course of action for your specific duct issues. In conclusion, Aeroseal is a reliable and effective technology for sealing ducts in homes. Its low VOC concentration, long-lasting results, and ability to improve air quality make it a popular choice among homeowners and contractors alike. However, it is important to understand its limitations and consult with a professional before deciding if it is the right solution for your duct problems.
