HVAC Ductwork; Are You Saving Energy or Losing?

 

In this blog, we’re being specific about the energy benefits of cleaning ducts.

There are plenty of claims out there from air duct cleaning companies, and here at Branch, we wanted to dig a little deeper and find some published data backing those claims. While there haven’t been many studies with reputable research organizations in this subject, we’ve found a few to glean from.

 

3 Energy Loss Facts

  • In a recent study, the University of Colorado at Boulder teamed up with the NADCA (National Air Duct Cleaners Association) to conduct an in-depth study on the association between HVAC performance and duct cleaning. Their study offers, “Cleaning a lightly-fouled system provides, on average, an 11 percent savings off of the energy used for heating and cooling.”
  • Research from the Environmental Protection Agency (EPA) and the Air Pollution Prevention and Control Division (APPCD) shows in an 8-house study in North Carolina that after mechanical duct cleaning was performed, supply air flows increased between 4-32 percent based on measurements taken at the floor registers and diffusers.
  • Another source from the EPA states that .042 inches of dust on the HVAC coil can reduce performance 21 percent.

Many HVAC systems, typically found in older homes, act as a reservoir for dust, bacteria, mold, trash, and build up of unknown particulates. Any of these contaminants can be harmful and pose negative impacts on the indoor air quality of your home and your health. While no two homes or families are alike, build up of particulates in the HVAC ducts is common and can result in a decrease in system performance.  Duct cleaning can be helpful, but isn’t necessary every time.
