Duct Cleaning Energy Savings Calculator

How Dirty Ducts Waste Energy

When dust, debris, and buildup accumulate inside your ductwork, your HVAC system has to push air through a restricted path. This forces the blower motor to work harder and run longer to reach your set temperature. The result: higher energy bills every month.

What the Research Says

According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling is wasted. Contaminants in the HVAC system cause it to work harder and shorten its lifespan. Even with filters, dust and dirt build up over time in your ductwork.

NADCA (the National Air Duct Cleaners Association) notes that a clean HVAC system does not have to work as hard to maintain your desired temperature. This translates directly into lower utility bills and a longer equipment life.

When to Clean Your Ducts

The general recommendation is every 3 to 5 years. However, homes with pets, smokers, allergy sufferers, or recent renovations should consider cleaning every 2 to 3 years. If you have never had your ducts cleaned, the potential energy savings from a single cleaning are typically the highest.
