As an HVAC expert, I have witnessed firsthand the significance of properly sealed air ducts. Not only does it enhance the efficiency of heating and cooling systems, but it also promotes a healthy indoor environment. One of the most effective solutions for duct sealing is using duct putty. This sticky substance is non-toxic, fire-resistant, and can last up to 20 years.
It is easy to apply and can be reshaped and reapplied when needed. Duct sealant is primarily used to block moisture, dust, and air movement, but it can also be utilized to reduce noise. It is non-conductive and non-corrosive, making it safe for use in various areas. However, it is important to note that duct sealant is mainly intended for air ducts and not for plumbing purposes. While working with appliances such as washing machines, refrigerators, or dishwashers, plumbers may also use duct sealant to protect electrical connections or ensure safety from nearby water sources. The best part about using duct putty is that it does not harden or dry out, making it easy to remove and reshape when necessary. It is crucial to follow the instructions provided with the sealant for optimal results.
The putty needs to dry and cure for 48 to 72 hours before turning on the air again. Depending on the size of the holes or cracks in the air ducts, you can use either sealing putty for small repairs or a putty sealer for larger ones. For a more thorough and professional job, it is recommended to hire a domestic air duct cleaning service that uses specialized equipment and technology to seal air ducts from the inside. The main difference between duct sealing putty and plumbing putty is the ingredients used to manufacture them and their melting points. Duct sealing putty is specifically formulated for use with air ducts and other heating and cooling components. One of the biggest advantages of using sealing putty for air ducts is that it is easy to clean up.
With gloves, goggles, and protective clothing, you can easily repair and seal air ducts on your own. This not only saves money but also ensures that your air ducts are properly sealed and functioning efficiently. Sealing putty for air ducts is also a cost-effective solution compared to other types of sealants such as tapes. It forms a permanent bond with the metal surface, making it a reliable option for sealing air ducts.
