Eight months of heating pushes a lot of air through your ducts

Your furnace runs from October through May here. Every time it cycles on, air moves through the same ducts, carrying dust and whatever else has settled near the return. Over eight months that adds up along the duct walls, and it does not clear out on its own.

Hendricks County has seen 10 winter storms and 71 damaging wind events over the past ten years. Storms like these can knock out power, and when a system shuts down hard and restarts, it can stir up what has settled inside the ducts and send it into the air headed for your living room.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home. If anyone in the house has allergies, if you have pets, or if you have just finished a renovation, get the ducts checked sooner rather than later. Otherwise, have a contractor look at them when you notice dust coming from the vents or a musty smell when the furnace runs.
Is air duct cleaning worth it?
It is worth it if your ducts actually have a buildup of dust, pet hair, or debris you can see or smell when the furnace runs. It will not fix an allergy problem on its own, and it will not lower your heating bills. Where it helps most is after construction work, a pest problem, or when a system has gone untouched for a long time.
What does air duct cleaning involve?
A contractor connects a vacuum to your duct system and uses brushes or air tools to loosen dust and debris along the way, then pulls it out through the vacuum. Each supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler itself, including the coil and blower, usually gets attention too since that is where a lot of buildup collects.
