Seven months of heat moving through the same ducts

Your furnace runs October through April here, seven months of the year. Every one of those months, air is moving through the same ductwork, and dust settles in it a little more each time the system cycles. On the nights that drop toward 28°F, the furnace runs longer and more often to keep the house warm, which means more air pushed through those ducts.

Boone County also gets its share of wind and winter storms, the kind that can cut power and shut the system down without warning. When it starts back up, it can stir loose whatever has built up since the last cleaning and send it straight into the rooms you're heating.

How often should air ducts be cleaned?
There is no fixed schedule that fits every house, but most homes do fine having it done every few years. If anyone in the house has allergies, or you have pets shedding into the return air, more often makes sense. Your ducts run for heat from October through April here, seven months a year, so dust and debris settle in whether or not you notice.
Is air duct cleaning worth it?
It is worth it if your ducts have visible dust, a musty smell when the furnace kicks on, or you cannot remember the last time it was done. It will not fix an undersized system or a leaky duct run, and it will not lower your utility bill on its own. What it does is clear out what has settled in there so the air moving through your house is cleaner.
What does air duct cleaning involve?
A contractor connects a vacuum to your duct system and uses brushes or air tools to knock loose dust and debris from inside the ducts, then pulls it out through the vacuum. Registers and grilles come off first, and the furnace or air handler gets checked too since it sits in the same air path. Arkansas requires a state license for this work, so the contractor doing it should hold one.
