Having the ducts of your home cleaned isn’t a task you probably have on a regular “to-do” list the same way you have heating and air conditioning maintenance. This is because duct cleaning isn’t something homes need done every year. In general, we recommend duct cleaning on a schedule of every 3 to 5 years or as needed.
The “as needed” part is what we wish to discuss here. Ductwork can become so choked with dust, lint, and other debris that it will end up affecting the HVAC system in multiple ways. Because you can’t easily see the interior of the ductwork, you may not know you’ve got a problem at first. We’ve put together a list of indicators that you’re due for duct cleaning.
