Contingent 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 some—you may adjust your air duct cleaning more or less regularly. So, how can you find out for sure when it’s time to have your ducts cleaned? There are definitely some revealing signs when it’s time.
