Step 1 of 3: Equipment
Ten months of heat running through the same ducts
Your furnace runs September through June here, which is most of the year. That is a long stretch of warm air moving through the same ductwork, and a long stretch of time for dust to settle in it between cleanings.
Most homes in Lawrence County are single-family houses people own rather than rent, the kind of home where one system serves the whole place for years. With winter nights averaging 13°F, that furnace is working hard for months at a time, pushing air through ducts that collect more the longer they go untouched.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If anyone in the house has allergies, or you've had duct work done recently, it's worth cleaning sooner rather than later. With heat running here from September through June, your system is moving air through those ducts most of the year, so dust and debris build up on a fairly steady basis.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts. If you can see dust blowing out of the vents, or there's a musty smell when the system kicks on, cleaning solves a real problem. If the ducts look fine and nobody in the house has breathing trouble, it's not something that needs to happen just for its own sake.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum. Every vent and return in the house gets cleaned, along with the main trunk lines. The furnace or air handler itself usually gets a look too, since dust collects around the blower and coil.
