Ten months of heating runs a lot of air through your ducts
Your furnace runs September through June here, which means ten months of the year air is moving through your ductwork almost constantly. On nights that average 4°F, the furnace cycles on and off many times to keep the house warm, pushing dust and debris through the same runs of duct over and over.
Williams County has also logged 23 winter storms and 84 damaging wind events over the past ten years. Storms like that can knock out power, and outages mean the furnace stops filtering and moving air the way it should until it comes back on. That buildup sits in the ducts and gets pushed back into the house once the system starts running again.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. If anyone in the house has allergies, or you have had renovation work that left drywall dust or insulation in the system, it makes sense to have them cleaned sooner rather than later. Homes with pets tend to need it more often too. A contractor can look at what is actually built up inside and tell you whether it is time.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If you can see dust coming out of the vents, or there is visible buildup when you pull a vent cover off, cleaning them will help the air moving through your house and can ease strain on your furnace. If the ducts look clean and nobody in the house has breathing trouble, you may not get much out of it beyond peace of mind.
- What does air duct cleaning involve?
- A contractor uses vacuum equipment and brushes to loosen and pull dust and debris out of the ductwork, working through the supply and return runs as well as the vents themselves. Some jobs also cover the blower compartment and the coil, if they can be reached. The whole system needs to be done, not just the vents you can see, because dust sitting in the hidden runs will just blow back out once your furnace kicks on.
