Eight months of heat means eight months of dust moving through your ducts

Your furnace runs October through May here, close to eight months out of the year. Every time it kicks on, air moves through the same ducts, and whatever is sitting in them gets pushed into the rooms you live in. On the cold nights that average 20°F, that furnace is cycling on and off for hours at a time, and the duct system is doing all the work of keeping the house livable.

Tazewell County has seen its share of wind and winter storms over the past ten years, the kind that knock out power and leave a house sitting cold and shut up for a stretch. Ductwork that sits still collects dust and debris, and the next time the furnace runs, that gets stirred up and carried right back into the house.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home. A contractor can look inside the ducts and tell you whether there's enough dust, mold, or pest debris built up to matter. Homes with pets or anyone with allergies tend to need a look sooner rather than later.
Is air duct cleaning worth it?
It's worth it when there's a real reason behind it, not just as a routine chore. Your furnace here runs October through May, eight months of the year, so if the ducts are dirty, that dust is moving through the house most of the year. A contractor can check for buildup before you spend money on a cleaning that might not be needed yet.
What does air duct cleaning involve?
A contractor loosens dust and debris from inside the ductwork, then vacuums it out with equipment strong enough to pull it from the whole system, not just what's near the vents. They'll typically check the supply and return ducts and the vent hoods, and sometimes the coil and blower if those are within reach. Once the work is done, any access points they opened get sealed back up.
