Yes, and often by more than homeowners realize. When dust, dander, and debris build up in your ducts, they restrict airflow throughout the system. Your HVAC unit must then work harder and run longer to maintain the temperature you’ve set, consuming more electricity or gas in the process. Over time, this constant strain can wear out parts like the blower motor or evaporator coil, leading to costly repairs. After a professional air duct cleaning in Stanley, NC, many of our customers report more even airflow between rooms, fewer system cycles per day, and even slight reductions in their monthly utility bills. If your home feels “stuffier” than it should or your system seems to run constantly, dirty ducts might be a hidden factor.
