Duct Sealing: Keep the Air That You Have Paid For

Posted by Paul Wadsworth on Wed, Sep 11, 2013 @ 04:24 PM

Ductwork is an important part of your central air conditioning system, and ensuring it's well-sealed is a big step in home energy efficiency. Ensure that your ductwork isn't the source of comfort, indoor air quality or efficiency problems by investing in duct sealing.

Leaky ductwork leads to decreased efficiency since some of the conditioned air will escape before it gets to where it's most needed. Leaks can also allow unconditioned air to be drawn into the ductwork, lessening the amount of conditioned air that's delivered.

duct sealing tipsLeaks result in especially large efficiency losses if they're present in ductwork located outside of the insulated area of the home. In this case, any air that escapes will be completely useless toward cooling or heating the home, and any air that infiltrates will be much warmer or colder than the air present in the home. Since the leakage is unlikely to be equal between different runs of ductwork, leaks can also lead to problems of unbalanced temperatures throughout the home.

Leaks can also create problems stemming from unbalanced return and supply airflow. When return and supply airflow isn't balanced, areas of your home can become pressurized. This further decreases efficiency and instead increases draftiness, which depending upon the season, allows hot or cold outdoor air to bypass your home's insulation.

Inadequate duct sealing can also contribute to poor indoor air quality. When areas of your home are pressurized, it can cause problems with fumes from combustion-fueled appliances, like gas water heaters, to be drawn into the home through back-drafting. If sufficient amounts of carbon monoxide (CO) build up due to this, it can present a serious safety hazard. Additional air quality problems can develop if air drawn in through duct leaks comes from areas where fumes or dust are present, like a garage or attic.
