Seven months of heating pushes air through the same ducts

Your furnace runs October through April here, seven months of the year. Every one of those months, the same ducts carry the air that heats your house, and dust sits in them the rest of the year too.

Forsyth County has seen 48 damaging wind events and 5 winter storms over the past ten years. Storms like that knock out power, and Georgia households went without it for a full day or more at a rate of 31% last year. When the system shuts down and starts back up, it stirs up what has settled in the ducts and pushes it back into the rooms you're heating.

How often should air ducts be cleaned?
There's no fixed schedule that fits every house. Clean them when you notice dust blowing out of the vents, when someone in the house has new or worsening allergies, or after work that left drywall dust or debris behind. If the air coming out looks and smells clean, the ducts are doing their job.
Is air duct cleaning worth it?
It depends on what's happening in your ducts right now. If you see dust building up around the vents, or you just finished a renovation that left drywall dust in the air, cleaning them out makes sense. If the ducts are just moving air quietly with no signs of buildup, cleaning them won't improve your air or change what you pay to heat and cool the house.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork, then uses brushes or air tools to loosen the dust and debris stuck to the inside of the duct walls so it can be pulled out through the vacuum. They also check the vent covers and the trunk lines near your furnace, since debris tends to settle there. The furnace filter is a separate part that catches dust before it enters the ducts, so it's not part of this job.
