Even if your home’s cooling and heating equipment is operating perfectly, your HVAC system will struggle to comfortably and efficiently condition your home if the ducts are leaking and/or require insulation. Leaky ducts alone can result in the loss of up to 30 percent of conditioned air before it arrives in the rooms of your home. That’s why effective duct sealing is essential for optimal home cooling and heating.

How Do You Know if the Ducts Are Leaking?

You can tell you’ve probably got duct problems if your summer and winter energy bills seem unusually high; some rooms are more difficult to cool and heat than others; some rooms remain stuffy no matter how the thermostat is set; uninsulated ducts run through unconditioned areas such as an attic, basement or garage; and you detect kinked or tangled duct sections.

What Are the Benefits of Duct Sealing?

Obviously, if the ducts aren’t leaking air, more conditioned air will arrive where it’s intended to go, in the various rooms of your home. This also means your HVAC system won’t have to work so hard to achieve the thermostat setting. This will save energy, require fewer repairs, and extend your HVAC system’s service life, in addition to improving comfort.

Duct sealing also prevents dirty air from getting sucked into holes and cracks in ducts, and contaminating indoor air. This can happen when leaky ducts run through areas such as crawl spaces, garages and attics. In addition to sealing ductwork in these areas, the ducts should be insulated; otherwise, they’ll lose heat energy to the areas outside the ducts in the winter, and gain heat in the summer.

Do-It-Yourself or Professional Duct Sealing?

While a handy homeowners can seal accessible ductwork with a combination of mastic sealant and quality metal tape, for a comprehensive job your best bet is to hire a professional HVAC technician who has the tools and know-how to do the job right.
