As an expert in the HVAC industry, I have seen firsthand the impact that duct sealing can have on the efficiency and effectiveness of air conditioning systems. Many homeowners may not realize the importance of properly sealed ducts, but it can make a significant difference in both energy savings and indoor air quality. So, how long does a duct seal last? The answer is that it should last several years, but there are certain factors that can affect its longevity. In extremely dry and hot climates, for example, duct seals may not hold up as well and may need to be replaced more frequently.
The Best Solution: Duct Putty
When it comes to duct sealing, there are various products on the market.However, in my professional opinion, duct putty is the best solution. This sticky material does not harden, is non-toxic, and is fire resistant. It is widely considered to be the top choice among industry professionals. Duct putty is typically applied with a caulking gun or spatula and can last up to 20 years. This makes it a long-lasting and reliable option for sealing air ducts.
It is also versatile and can be used on both metal and flexible ductwork.
DIY vs Professional Duct Sealing
While some homeowners may be tempted to tackle duct sealing as a DIY project, I highly recommend leaving it to the professionals. Properly sealing ducts requires knowledge and experience to ensure that all leaks are properly sealed and that the job is done correctly. If you have rigid pipe ducts with insulation wrapped around them, you'll need to remove all of the insulation, seal any leaks, and then replace the insulation. This can be a time-consuming and challenging task for those without experience in HVAC work. By hiring a professional, you can rest assured that the job will be done correctly and efficiently. Plus, many HVAC companies offer warranties on their work, providing added peace of mind.The Money-Saving Benefits of Duct Sealing
One of the main reasons why homeowners should consider duct sealing is for its money-saving capabilities.When air ducts are properly sealed, air conditioning does not leak through the ducts before reaching the ventilation grilles. This means that you are getting the full benefit of your air conditioning system and not wasting energy. In addition, properly sealed ducts also prevent heat loss or gain due to lack of insulation. This can result in significant energy savings, especially during extreme temperatures.
Choosing the Right Company for Duct Sealing
If you are considering a duct sealing project, it is essential to choose the right company for the job. Look for companies that specialize in attic work or energy-saving projects.These companies will have the necessary expertise and experience to properly seal your ducts and ensure maximum efficiency. It is also important to do your research and read reviews from previous customers. This will give you an idea of the company's reputation and the quality of their work.
The Benefits of Sealed Ducts
Aside from energy savings, there are many other benefits to having properly sealed ducts. One of the most significant advantages is improved indoor air quality. When ducts are leaking, they can allow outside pollutants such as dust, pollen, and other allergens to enter your home.This can lead to respiratory issues and allergies. Sealing the ducts helps close any gaps, making it nearly impossible for these air pollutants to enter. This can greatly improve the overall air quality in your home, creating a healthier and more comfortable living environment.
