Sealing the Ductwork Promotes Optimal Furnace Efficiency

Posted by Paul Wadsworth on Wed, Sep 25, 2013 @ 04:19 PM

Sealing the ductwork in your northern Ohio home is a simple, low-cost way to keep your heating and cooling system working at top efficiency. No matter how efficient your air conditioner or furnace, they can't heat your home efficiently unless your ducts are also performing correctly. Sealing the ductwork allows the ducts to work as designed.

sealing ductworkIt's your air conditioner's and furnace's job to cool or warm air efficiently, but your ductwork is responsible for getting that conditioned air into your living space. The branching system of ducts that runs through your home is made of many connected duct sections. Often, these sections are only pushed together, leaving space for air to escape from the joints.

Duct sections sometimes become disconnected, deteriorate or develop holes, which also allows air to leak. The points where ducts connect to the air conditioner and furnace unit, registers and grilles are leak-prone too.

Unsealed ducts passing through unconditioned spaces like the garage, attic and crawl spaces can lose an especially large amount of air. Altogether, if your home is typical, your unsealed ducts may be leaking up to 20 percent of your conditioned air before you ever feel it.

Signs of leaky ducts include:

  • High energy bills all year
  • Certain rooms that are hard to heat and cool
  • Your furnace or A/C running most of the time, yet not improving the temperature much
  • Rooms that feel stuffy
  • An excessive amount of dust in your rooms

By sealing the ductwork, you'll ensure all the conditioned air traveling through your ducts reaches your rooms where you can enjoy it. This lets you use your air conditioner less and turn down your thermostat in winter, which lowers your heating costs.

You can seal minor leaks in easily accessible parts of your ductwork yourself using mastic or UL 181B-labeled tape, such as foil-backed butyl tape. For optimal results, though, consider hiring a professional who'll use equipment to pinpoint all your leaks and can access areas you may not be able to.

Take advantage of duct sealing to reclaim your lost energy and rein in your heating and cooling bills.
