The Truth About Duct Seal Longevity

Learn about the longevity of duct seal and its effects on your HVAC system from an expert in the field. Find out how often you should check and maintain your air ducts and the differences between oil-based and water-based sealers.

The Truth About Duct Seal Longevity

As an HVAC expert, I have been asked numerous questions about duct sealing and its longevity. One of the most common questions is whether or not duct seal dries out over time. In this article, I will provide you with all the information you need to know about duct seal drying and its effects on your HVAC system. First and foremost, it is important to understand what duct sealing is and how it works.

Duct sealing is the process of sealing any leaks or gaps in your air ducts to prevent air from escaping. This helps to improve the efficiency of your HVAC system and can also improve indoor air quality. There are various types of duct sealers available in the market, including oil-based and water-based sealers. Now, let's address the main question at hand - does duct seal dry out? The answer is no. Once the putty is spread and the ducts are sealed, it will remain supple and flexible for years to come.

This means that you don't have to worry about it hardening or drying out over time. In fact, a high-quality sealing material and an effective sealing method can give good results for many years. However, it is important to note that sealants can degrade over time. This means that new leaks can form as your ducts age or change. Therefore, it is recommended to regularly check and maintain your air ducts to ensure that they are properly sealed. If you are planning on replacing your air conditioner or making any changes to your HVAC system, it is a good idea to reseal your ducts as well.

This will ensure that your system continues to function efficiently and effectively. Now, let's take a closer look at the differences between oil-based and water-based duct sealers. Oil-based sealers are made with petroleum-based ingredients, while water-based sealers are made with water and other non-toxic ingredients. The main advantage of water-based sealers is that they are non-toxic, making them safe to use in areas with poor ventilation or limited access to safety equipment. Another important factor to consider is the drying time of duct sealers. Water-based sealers tend to have a longer drying time compared to oil-based sealers.

This means that you may have to wait longer for the sealer to dry before making any changes or adjustments to your ducts. So, how long will the duct sealing compound last? The longevity of duct sealing can vary depending on the sealing material and other factors such as the quality of installation and maintenance. However, with proper installation and regular maintenance, a good duct sealer can last for many years. In conclusion, duct seal does not dry out over time. It remains flexible and supple for years, making it an effective solution for sealing air ducts. However, it is important to regularly check and maintain your ducts to prevent new leaks from forming.

With the right sealing material and proper installation, you can enjoy the benefits of a well-sealed HVAC system for many years to come.
