Nine months of heating means nine months of dust moving through your ducts
Your furnace runs September through May here. That is most of the year, and every time it cycles on, air pushes through the ducts and carries dust and dander onto the coil, the blower wheel, and the inside of the ductwork itself. On nights averaging 15°F, the furnace is running long and often, so more air moves through those same ducts more times a day.
Manitowoc County has seen 25 winter storms and 52 damaging wind events over the past ten years, and storms like these knock out power. When the furnace stops and starts back up around an outage, it pulls in whatever has settled in the ducts since the last cycle. In a county where most homes are single-family and owner-occupied, that buildup is something the homeowner deals with directly, not a landlord.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than homes without those things. Your furnace here runs nine months of the year, September through May, so dust and debris pass through that system for most of the year, and a contractor can look inside the ducts and tell you what condition they are in.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If you see dust coming out of the vents, smell something musty when the furnace kicks on, or know there has been rodent activity or construction dust in the house, cleaning solves a real problem. If none of that applies, a contractor can look inside and tell you whether cleaning will do anything or whether your ducts are fine as they are.
- What does air duct cleaning involve?
- A contractor connects vacuum equipment to your duct system, then agitates the inside of the ducts so dust and debris break loose and get pulled out rather than blown back into the house. This usually covers the supply and return ducts along with the grilles and registers, and the coil and blower too if they can be reached. Checking the furnace filter is part of a thorough job, since a dirty filter puts the dust right back into the air you just cleaned.
