Ducts: Out of sight but so important

Ducts are round or rectangular tubes that carry hot or cool air from forced air furnaces to your living space. These often-overlooked components are usually located out-of-sight – inside walls, crawlspaces, basements and attics, but they have a big impact on the efficiency and comfort of your home. Common problems with ducts include leaky, torn, and disconnected ducts, poorly sealed registers, uninsulated ducts, and kinks in flexible ductwork that restrict airflow.

Higher bills, uncomfortable home

In a typical house with forced air heating and cooling, 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and gaps in connections. This waste leads to higher utility bills and difficulty keeping the house warm or cool, regardless of the thermostat settings or efficiency of the heater or air conditioner.

Unhealthy air

Leaky ducts can also bring moisture, dust, spores and allergens from crawl spaces into living space, resulting in poor air quality and potential health impacts. Leaky ducts can also pull in combustion gases from natural gas furnaces and water heaters, leading to unsafe air inside your home.

How to know if your ducts are leaking

If your house seems difficult to heat or cool, and ducts are located in difficult-to-access spaces like the attic, crawl space or garage, it can be hard to know the whether they are leaking. A professional home assessment can help determine where you might have problems with ducts. After your assessment, you’ll learn about opportunities for duct repair, duct sealing, duct insulation as well as other energy efficiency measures like new windows and attic, floor and wall insulation. Your contractor will recommend upgrades to address your needs and Community Energy Project provides access to financing options if upfront costs are a concern.
