How to Tell if Your Ducts Need to be Cleaned

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

Look for these clues:

  1. Are your cold air returns coated with dust or pet hair?
  2. Is there a blockage within 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 sound 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 more than likely time to ask O'Brien Heating & Air Conditioning in the Main Line about air duct cleaning.

Prolonging Time Between Air Duct Cleaning
There are a few things you can do to help keep your ducts cleaner and extend the timeline between specialized cleanings.

Mostly importantly, arrange routine HVAC maintenance with the specialists at O'Brien Heating & Air Conditioning. A maintenance check of your furnace each fall and your AC each spring, which should include inspection, and possible replacement, of your air filter, will help keep your HVAC system operating efficiently, and may help keep your ducts clean.

You can also talk to the team at O'Brien Heating & Air Conditioning about installing an air purification system. We offer the Lennox PureAir Air Purification System, Healthy Climate Carbon Clean 16 Media Air Cleaner, Healthy Climate 11 Media Air Cleaner, Healthy Climate High-Efficiency Particulate Air (HEPA) Filtration System and Healthy Climate UV Germicidal Lights.

Other measures you can take include:

  • Frequently dusting and vacuuming your home.
  • Inspecting your air filters routinely and exchanging them when the manufacturer recommends changing them. Most filters will show dust on them after a short time in service, but they may not require replacement.
  • Sealing leaks in air ducts that allow dust to come in from areas like your attic.
  • Trading poor or impaired air-duct insulation.
