Leaky Ducts Cause Unseen Problems

Leaky Ducts

Leaky ducts aren’t easy to spot. However, just because you can’t easily see air leaking from your heating or cooling system doesn’t mean it’s not happening. Supply ducts run air from your air conditioner, furnace, or heat pump and supply warm and cool air to your home. But when this system has leaky connections, all that conditioned air is being lost in your crawlspace or attic. You might ask, “What’s the big deal with leaky ducts?”

There are actually several reasons why a sealed duct system is important. In fact, properly sealed ductwork improves your family’s comfort and health – and even decreases your energy bills and maintenance costs.

Eliminate Leaky Ducts to Keep Your Family Comfortable

A well-insulated home that has tightly sealed ductwork will feel comfortable, no matter the season. If part of your home is cozy warm in the winter, but other areas are drafty and cool, there might a be hole in the ductwork leading to that part of the house. This could lead to thermostat wars, with one family member burning up while the other reaches for sweaters and socks!

Air Quality Matters

Are you seeing dust sitting on tabletops or floating in the air? Not only is this a cleaning annoyance, but it can also be evidence of leaky ducts. Leaky ducts suck up dirt, dust, and other debris that’s found in your attic or under the house. Then, all that stuff gets pumped directly into your home – affecting the air quality and potentially affecting your family’s health.

The dust coming into your home can also clog your air filters more quickly. This can lead to poor air quality and high electricity bills because your heating or cooling system is working harder than it should be to push air through the filter. What’s more, you’ll have to change your air filters more often. You may even need to maintain your heating and cooling system more frequently because of the extra work it’s doing.

Say No to Mold and Mildew

Leaky ducts can also lead to mold and mildew – agents known to cause breathing problems and sickness. When your home is cool, warm outside air can come in through gaps in your ductwork and around windows and doors. When the warm air comes into contact with cooler walls, it can condense into water and allow mold to grow inside your home.

If you suspect problems with leaky ducts, you can take a DIY approach by sealing air leaks with mastic sealant or metal tape and insulating ducts you can reach (like in your crawlspace, basement, garage, and attic). Some ductwork is in hard-to-reach areas, which makes it necessary to work with a professional to both find and effectively seal leaks throughout your home.
