Eight months of heat pushes a lot of air through your ducts
Your furnace runs October through May here, close to eight months a year. On the nights that drop to 21°F, it runs long and often, pushing air through the same ducts over and over. That kind of use moves dust and pet hair into the runs and lets it settle in the bends where the air slows down.
Winter storms and wind events are common here too. When the power drops out, the system sits still and whatever is loose in the ducts settles further before it starts back up and blows through the house again.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house, but a contractor can tell you what your ducts look like inside before deciding. If anyone in the house has allergies, or you have pets shedding into the return vents, or you just finished a renovation with a lot of drywall dust, get it looked at sooner rather than later. Homes here run the heat October through May, eight months of the year, so dust and dander have a long stretch to build up in the ductwork between heating seasons.
- Is air duct cleaning worth it?
- Yes, when there's a real reason for it, like dust coming out of the vents, a musty smell when the furnace kicks on, or someone in the house with breathing trouble that gets worse indoors. It won't lower your heating bills or add years to your furnace, those are separate things. What it does is clear out what's built up in the ducts so the air moving through your house is cleaner.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum before it can resettle in the ducts. Every supply and return vent gets covered, along with the main trunk lines. The furnace or air handler itself usually gets cleaned too, since that's where the air picks up whatever is sitting in the ducts.
