No need to duck this question as if it’s only something the pros know. As a homeowner, you’ve got a clear view of how your ducts are doing.
Heating and cooling systems rely on ducts to move heated or cooled air among the rooms in your home. When everything’s working, you’ll be nice and comfortable wherever you are. But if your ducts are falling down on the job, it’ll create comfort inconsistencies that no amount of thermostat fiddling can fix.
In a typical home, leaks, holes or poorly connected ducts are trouble spots that waste about 20 to 30 percent of the air moving through duct systems. Though you might not spot the holes on your own, you’ll sure notice when all that air-loss adds up to higher energy costs.
The first signs you see will look something like the following:
- High winter and summer utility bills
- Rooms that are difficult to heat and cool
- Rooms that are stuffy and never feel comfortable
- Ducts located in an attic, crawlspace or garage
- Flexible ducts that are tangled or kinked
A well-designed and properly sealed duct system resolves these issues, improving comfort and energy efficiency, as well as indoor air quality and safety. If dust, insulation particles and chemical fumes enter leaky ducts and recirculate through your home, allergies and asthma symptoms may worsen. Similarly, leaky ducts could enable “back drafting” from gas appliances, drawing gases like carbon monoxide back into the living space instead of ventilating outdoors.
