About air ducts — what you need to know for regular maintenance

Posted on Feb 13, 2019

In the past, we’ve discussed why having your air ducts cleaned regularly is important. But what does cleaning your air ducts actually mean? For new homeowners or those who have never had their duct system professionally maintained, you may have questions about what the process entails. We want to clear up some of the confusion around air duct cleaning, so you know exactly what you’re getting!


Air duct cleaning generally refers to the cleaning of the different parts of your heating and cooling system, or your HVAC unit. These units can become clogged with debris, infested with insects or vermin, or infested with mold if not properly cleaned. 

Commercial vs. residential vs. industrial

This refers to the type of building that the HVAC unit resides in. Commercial buildings would be places where businesses (such as offices, store fronts or grocery stores) reside, while residential is a home or place where someone lives. Industrial air duct cleaning might refer to a manufacturing plant or similar building.

The different parts

HVAC systems and air ducts vary based on the type of building (such as commercial or residential) as well as the size of the building. However, for the most part, when you hire a professional duct cleaning service, they will clean the supply and return air ducts, registers, grilles, diffusers, heat exchangers, heating and cooling coils, drip or drain pans, fans and motors, as well as the air handling unit housing. While they’re cleaning, they’ll be able to evaluate the condition of your unit and may spot some potential issues before they become a problem.
