Why You Should Have Your Air Ducts Sealed

Why You Should Have Your Air Ducts Sealed

The air ducts that run throughout your home are integral to your quality of life. Not only do they carry the air that your central heating and cooling system produces, but they also keep that air protected and clean of the debris that could be around it. However, they can only do this if they are perfectly air-tight and free from gaps, cracks, or other leaks that allow this conditioned air to leak out and contaminants to get in.

Air ducts can accumulate everything from dust to pollen to mold and mildew over time thanks to leaks, cracks, and other flaws of various shapes and sizes. However, they can also get in through your central HVAC system itself—if your air filter is dirty or the contaminants are small enough to find their way through, they can cycle through your home via your duct system. What can you do to prevent this problem and keep your HVAC system running as efficiently and effectively as possible? The answer may be easier than you thought: duct sealing.

Don’t Replace Your Air Ducts, Seal Them!

Duct sealing is a process that closes off any gaps or leaks in your air duct network. Duct sealing is generally a fast process—it can usually be completed in about a day and you’ll have full use of your HVAC system again in as little as 24 to 48 hours. There are two different types of duct sealing: interior and exterior; both processes seal everything from pinhole leaks or hairline cracks and can even stop significant gaps of up to roughly a centimeter in width. While they can’t repair completely separated air ducts, sealing can repair things like minor damage from animals or holes that have emerged from rusting and corrosion—something not at all uncommon in ducts constructed from sheet metal. Sealing also helps prevent the spread of rusting and corrosion by preventing moisture and oxygen from impacting the inside of your air ducts.

The interior sealing process uses a specialized liquid substance that’s sprayed throughout the inside of your air duct network and then spread around evenly using a specialized tool. This specialized liquid then dries to form a clean, hypo-allergenic seal that prevents air loss through small leaks and stops things like mold and mildew growth for significantly improved air quality.

The exterior sealing process is pretty similar to a spray foam insulation application. Your technician uses a specialized application tool to spray the exterior of your air ducts with a fine liquid that reacts with the air in your attic or around your home. The reaction causes the liquid to quickly expand into a durable, thick, and extremely versatile foam.

Why Should I Seal My Air Ducts?

Is duct sealing something you should strongly consider investing in? Absolutely. The benefits of doing so are numerous and extremely valuable, making duct sealing one of the single greatest investments you’ll make both in your home comfort and in your energy consumption. Here are a few of these outstanding benefits.

  • Improved HVAC efficiency: A single, small air leak in your duct system can cost you several dollars per year in lost energy. Several leaks can compound this effect over and over again. Before you know it, you might be losing hundreds of dollars a year to energy loss through leaks in your duct system. Sealing your ducts prevents this and keeps the air flowing through your ducts as much as possible.
  • Better in-home comfort: Sealed air ducts allow your existing HVAC system to heat or cool your home better. When they don’t have to work as hard to heat or cool your home, you’ll enjoy more consistent temperatures. More consistent temperatures means a better overall quality of life at home.
  • Better air quality: Sealed air ducts prevents unwanted debris from finding its way in. If you struggle with air quality problems or have a condition like severe allergies, asthma, or another respiratory issue, sealing your air ducts can do wonders for keeping your air quality high and making home life more enjoyable.

How Often Should I Seal My Ducts?

A proper duct sealing service can last for decades. Different processes have different longevity expectations, but most processes will last at least 20 years before needing replaced. In fact, sealing your duct system can often extend its lifespan many additional years. You may only have to invest in this service once throughout the entire time you own your home!
