AC Filter Cleaning vs Duct Cleaning: What’s the Difference?

These terms get used interchangeably, but they mean different things, and you should not pay for more than you need. Here is the plain-language difference.

Filter cleaning

The quickest, cheapest service. We wash the filter to restore airflow. Great between full services, but it only addresses the filter.

Deep cleaning (the unit)

Services the indoor unit, coil, blower, drain and filter. This is what helps most with weak cooling and smells caused by the unit itself.

Duct cleaning

Focuses on the ducts and vents that carry the air through your home. Best when there is dust build-up in the duct runs and grilles.

Which do you need?

That is exactly what an inspection answers. Rather than guessing, a quick DuctCam and airflow check tells you which service is worth doing, or whether you need one at all.
