How to Tell if Your Ducts Need to be Cleaned

Service

Typically, air ducts need to be cleaned every three to five years according to the National Air Duct Cleaners Association. Depending on a lot of factors—like your home’s location, if you have pets, and how often your air filter has been swapped out, to name a few—you may need to have air duct cleaning more or less regularly. So, how can you tell for sure when it’s time to have your ducts cleaned? There are certainly some significant signs when it’s time.

Look for these clues:

  1. Are your cold air returns covered with dust or pet hair?
  2. Is there a jam in your cold air return vent?
  3. Are your registers blowing out dust?
  4. When you check inside with a flashlight, can you see a collection of debris or pet fur?
  5. Have insects or rodents found shelter in your ductwork?
  6. Can you hear noise other than your blower motor when you listen to the airflow?
  7. When your vents are fully opened, do any have a smaller amount of airflow than others?

If you answered “yes” to any of these questions, it’s most likely time to ask Kelley Mechanical in Lexington about air duct cleaning.
