Signs It’s Time to Get Your Air Ducts Cleaned

September 21, 2021

For homes with central HVAC systems, the air ducts serve as the highway for fresh air—whether heated by a furnace or cooled by an air conditioner—to circulate throughout every room of the house. When those ducts are full of dust, dirt and other pollutants, it not only is a nuisance for everyone in the household, but it can also be a health hazard. Here’s how to tell when you need your air ducts cleaned.


Being vigilant against mold and getting it handled as quickly as possible is one of the most important air duct cleaning tips. If you notice mold growing within your ducts or on the fixtures of your HVAC system, immediate cleaning is required. Mold poses a major health risk to anyone within the house, whether your immune system is healthy or not.


If you’re smelling a new, unpleasant odor coming from your air ducts, it’s a clear sign you need air duct cleaning. Get up close to the vents so you can verify that the source of the smell is coming from the ducts.

Poor airflow

Noticing low airflow when the air conditioner or heater kicks on? All vents throughout your home should have consistent airflow. If you don’t feel sufficient airflow coming through your system, dust or debris could be clogging your air ducts. Contact a duct cleaning professional right away to restore a healthy flow of air throughout the house.


It shouldn’t come as too much of a surprise that homeowners shouldn’t have insects or rodents taking up residents in the air ducts throughout their home. Usually, it’s easy to spot an infestation—you might hear noises or see animal droppings, among other signs. After you’ve had an exterminator take care of the unwelcome intruders, it’s smart to call in an expert to get your air ducts professionally cleaned, since removing bacteria and contaminants from your air ducts is the best way to ensure you maintain a healthy indoor air quality in your home.

Clogged dust and debris

One of the simplest ways to tell if your air ducts need cleaning is by checking for clogged dirt, dust and debris. It’s especially important to get your ducts cleaned regularly if you or a family member suffer from allergies or other respiratory ailments. If you’ve noticed that you or a member of your household experience illness more often, the cleanliness of your air ducts may be to blame. Contact your local duct cleaning professionals to prevent recurring sickness and turn your ducts into an air delivery system rather than a germ delivery system.

Knowing how to tell when you need your air ducts cleaned promotes healthy indoor air quality in your home.
