Step 1 of 3: Equipment
Eight months of heat means eight months of dust moving through your ducts
Your furnace runs October through May here, eight months out of the year. Every time it kicks on, air pushes through the ductwork and stirs up whatever has settled inside since the last cycle. On nights that average 24°F, that furnace is cycling on and off for months straight, and each pass moves more dust and debris through the same runs of duct.
Over eight months of that, the buildup lines the inside of the ductwork and works its way into the air the house breathes. A duct system that never gets cleaned just keeps recirculating what has collected in it, winter after winter.

- How often should air ducts be cleaned?
- Most homes do fine having ducts cleaned every few years, not every year. If anyone in the house has allergies, or you can see dust building up around the vents, it's worth doing sooner. Homes here run the furnace from October through May, so ducts see more use than they would somewhere with a shorter heating season, and that extra runtime pushes more dust through the system.
- Is air duct cleaning worth it?
- It's worth it if your ducts are visibly dirty, if you've had rodents or a pest problem, or if you just finished a renovation that left drywall dust behind. It won't fix an allergy problem on its own and it won't lower your energy bill in any way you'd notice. What it does is clear out debris that's actually built up inside the ducts, so the value depends on how much is really in there.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to knock loose dust and debris from inside the ducts before pulling it out through the vacuum. Every supply and return vent gets cleaned this way, and the furnace or air handler itself usually gets attention too, since dust collects on the blower and coil the same way it does in the ducts. The registers and grilles get wiped down at the end.
