As an expert in the field of heating, ventilation, and air conditioning, I have encountered numerous methods for sealing leaking air ducts. While adhesive tape may seem like a quick and easy solution, it is not always the most effective or cost-efficient option in the long run. That's why I always recommend using an air duct sealant with putty for the best results. This type of sealant is a sticky substance that hardens after being applied to the ducts. It creates a strong and durable seal that can last for years.
But not all duct sealants are created equal. In my experience, the best option is to use a water-based putty. Not only does it clean up easily, but it also has a longer lifespan compared to other types of sealants. One of the biggest challenges when it comes to sealing leaking air ducts is reaching all areas of the ducts. This is where putty can be tricky to work with.
You need to be careful not to let any putty enter the ducts, especially in important gaps that need to be filled. That's why I highly recommend using Aeroseal, which uses patented technology to pressurize the duct system and identify and seal each leak individually. If you're concerned about the air quality in your home, sealing leaking air ducts should be at the top of your list. Leaking ducts can allow contaminants and pollutants to enter your home, affecting your health and comfort. By properly sealing these leaks, you can improve your home's indoor air quality and create a healthier living environment for you and your family. But why choose putty over other methods of sealing ducts? Well, for one, it is a cost-effective option that you can do yourself.
However, it does require some careful application and can cause problems if not done correctly. For example, if your ducts have insulation around them, you'll need to remove it before applying the putty. Then, once the leaks are sealed, you'll need to replace the insulation. It can be a time-consuming process, but the results are worth it. If you do decide to use putty to seal your ducts, make sure to use a high-quality duct sealing tape as well.
Look for tapes that are marked with the UL logo, such as aluminum tape or butyl tape. These tapes are specifically designed for sealing ducts and will provide an extra layer of protection. At the end of the day, a properly sealed duct system can have many benefits for your home. Not only will it improve your indoor air quality, but it can also increase energy efficiency and reduce utility bills. As a heating, ventilation, and air conditioning contractor, I have found that the best way to achieve a perfect seal is by using a combination of duct putty and adhesive tape.
