Duct sealing eliminates air leakage in ducts, improving the efficiency of your HVAC system.

Whether located in the basement, attic, or crawl space, your ductwork is an essential part of your home's energy efficiency and comfort. Due to joints, screw holes, and other gaps, ductwork is inherently leaky and inefficient. Air loss from your ducts makes your HVAC system less efficient, costing you money and making your home uncomfortable.

Triple H Insulation can solve these problems in your home with our complete duct sealing services for attic, basement, and crawl space ducts. Our duct sealing methods create an airtight barrier around your ductwork, preventing air loss and helping your system run more efficiently.

Why is duct sealing important?

Learn how properly sealing ducts in the attic can prevent air leakage.

Your ductwork system has an important job: distributing air that has been "conditioned" (heated or cooled) throughout the house so that your living space can be at the right temperature. Supply Ducts transport conditioned air from your furnace or air handler to different rooms or hallways.

A separate system of Return Ductwork brings air back to the furnace or air handler to be reconditioned.

In theory, a ductwork system sounds fairly basic. But there are several problems that shouldn't be allowed to persist because of their adverse effects on your comfort, health, and utility costs.

Common ductwork problems

Attic ductwork Many ductwork systems combine flexible ducts with rigid sheet metal ductwork, as shown here. The uninsulated sheet metal duct has no protection from extreme attic temperatures that make the heating and cooling system work harder and longer than necessary.

  • Leaky ducts are very common and can compromise the efficiency of your HVAC system. It doesn't make sense for air that you've paid to heat or cool to leak into an attic, basement, or crawl space through gaps and cracks in your supply ducts. And it's not healthy to breathe crawl space or attic air that's sucked into leaky return ducts and then circulated back to your living space. Fortunately, these problems can be corrected by sealing your ductwork system.
  • Uninsulated or poorly insulated ducts waste a tremendous amount of energy. Just think about what happens in the winter, when your system is blowing heated air through uninsulated ducts located in a frigid attic! Before your HVAC system can heat your living space, it must first heat up the attic ductwork. In the summer, you're blowing chilled air through the same uninsulated ductwork, that's been heated to about 120 degrees.
  • Imbalanced ductwork wastes energy while also creating areas in your house that are too hot or too cold. Balance problems occur when the amount of air delivered through supply ducts doesn't match the amount of air drawn in through your return ducts. This typically occurs because of improper location and size of supply and return ducts.
  • Safety: Pressure imbalances caused by air duct leakage can lead to back-drafting in combustion appliances such as furnaces, wood stoves, and gas ranges. When this happens, you risk exposure to carbon monoxide.

Reliable Duct Sealing by Triple H Insulation

Your home's energy efficiency, comfort, and heating and cooling expenses are all affected by the performance of your ductwork. When your crawl space, attic, or basement ducts operate with less than maximum airflow, your heating or cooling system needs to run longer to get your home to the right temperature. This naturally wastes energy and money while also forcing you to wait for a comfortable temperature in the home.

Spray foam duct sealing air seals and insulates in one step, providing maximum efficiency.

At Triple H Insulation, we offer two methods of duct sealing:

  • Duct mastic: Duct mastic is a compound specifically designed for duct sealing. It is used to seal joints, gaps, and any other leakage points in the ductwork to ensure maximum airflow through the duct system.
  • Spray foam: Spray foam provides duct sealing and insulation in one step. The entire duct system is sprayed to completely seal any and all leaks. Once installed, the spray foam insulation will also keep your ducts at a more consistent temperature, which means the air you pay to heat and cool will maintain the right temperature as it moves through your ducts.

For best results, we always recommend homeowners pair duct sealing with duct insulation. Together, these solutions maximize the effectiveness of your duct system and will help save you money on heating and cooling bills.
