Ten months of heating puts a lot of air through your ducts
Your furnace runs September through June in Lovell, close to ten months of the year. That is most of the year pushing air through the same ductwork, and every pass carries a little dust and debris that settles in the bends and joints instead of blowing back out through the vents.
Winter nights here average 12°F, cold enough that the furnace cycles on and off for hours at a stretch on the worst nights. Each cycle pushes more air, and more of what is riding in it, through the same runs of duct. Over ten months that buildup adds up, and it sits there until something moves it back out into the air the furnace is heating.

- How often should air ducts be cleaned?
- Most homes do fine having ducts cleaned every few years, not on a fixed schedule. Watch for the signs instead. Dust settling around the vents again soon after cleaning, a musty smell when the furnace kicks on, or work that was just done on the ductwork itself. Homes here run the furnace September through June, so ducts here are moving air most of the year, which is more reason to deal with a problem when you see one rather than wait.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason for it, like dust coming out of the vents, a musty smell when the system runs, or work that was just done on the ductwork itself. It will not fix an allergy problem on its own and it will not lower your heating bill. If nothing seems wrong and you are not sure it is needed, a contractor can look at the ducts and tell you whether cleaning will actually help.
- What does air duct cleaning involve?
- A technician connects a vacuum to the duct system, then works through each run with brushes or air tools to knock dust and debris loose so it can be pulled out. The supply and return vents get cleaned along with the main trunk lines. The coil and blower housing are usually checked too, since dust collects there as well. The filter gets replaced or noted for replacement, because a clean duct system feeding through a dirty filter does not do much good.
