Seven months of heating pushes air through ducts that rarely get a break

Your furnace runs October through April here, seven months of the year. On the cold nights, down around 28°F, it cycles on and off for hours at a stretch, pulling household dust, pet hair, and whatever settled in the ducts over summer through the system and back into the rooms you live in.

Payne County also sees its share of wind and winter storms, 83 damaging wind events and 7 winter storms over the last ten years. When storms knock the power out, and a quarter of Oklahoma households lost power for a day or more last year, the system sits still and dust settles into the ducts instead of moving through them. Once the power is back and the furnace kicks on, that settled dust gets stirred up again.

How often should air ducts be cleaned?
Most homes do fine having it done every few years, though there is no fixed number that fits every house. Pets, a recent renovation, or someone in the house with allergies can be reasons to do it sooner. If a contractor opens a return and finds heavy dust or debris built up inside, that is a better sign to go by than any schedule.
Is air duct cleaning worth it?
It depends on what is going on in your ducts right now, not on a fixed answer that fits every house. If dust keeps settling back on furniture soon after you clean, or you can see debris in the vents, cleaning solves a real problem. If your ducts look fine and no one in the house has breathing trouble, there is less to gain. A contractor can look at your system and tell you whether it needs it.
What does air duct cleaning involve?
A contractor uses a machine to create negative pressure in the duct system, then agitates the dust and debris loose with brushes or air tools so it gets pulled into a collection unit rather than blown into your rooms. Every supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler itself, including the blower and coil, often gets cleaned in the same visit since air moves through it constantly.
