How to Tell if Your Ducts Need to be Cleaned

February 09, 2017

 

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, how many pets you have, and how frequently your air filter has been replaced, to name a handful—you may adjust your air duct cleaning more or less frequently. So, how can you know for sure when it’s time to have your ducts cleaned? There are certainly some telltale signs when it’s time.

Look for these clues:

  1. Are your cold air returns caked with dust or pet hair?
  2. Is there a blockage in your cold air return vent?
  3. Are your registers wafting out dust?
  4. When you look inside with a flashlight, can you see an accumulation 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 less airflow than others?

If you answered “yes” to any of these questions, it’s probably time to ask American HVAC Inc in San Jose about air duct cleaning.
