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

Your furnace runs October through May here. That is most of the year moving air through the same trunk lines and branches, and every pass carries dust and whatever else is in the house along with it.

Winter nights average 13°F from December through February, so the furnace is cycling on and off often to keep up. Each cycle pushes more air, and whatever is sitting in the ducts, through the house.

How often should air ducts be cleaned?
Most homes do fine with a cleaning every few years, and a contractor can tell you what's right after a look at your ducts. If anyone in the house has allergies, or you've had a pest problem or water damage in the ductwork, it's worth doing sooner. Homes here run the heat from October through May, so ducts stay in near-constant use most of the year and collect dust and debris steadily during that stretch.
Is air duct cleaning worth it?
It's worth it if your ducts actually have a buildup problem, dust, debris, or signs of rodents or mold. It won't lower your heating bills or fix an airflow problem caused by something else, like a clogged filter or a closed vent. A contractor can look at the ducts and tell you honestly whether cleaning will help your situation or whether the issue is somewhere else.
What does air duct cleaning involve?
A technician connects a vacuum system to your ductwork, then uses brushes or air tools to knock loose dust and debris while the vacuum pulls it out. They work through each supply and return duct, along with the grilles and registers, and check the coil and blower housing since debris collects there too. The furnace filter still needs its own regular changes after the cleaning is done, since the filter and the ducts do different jobs.
