Seven months of forced air moves a lot through your ducts
Your furnace runs October through April here, close to seven months a year. Every one of those months your blower is pushing air through the same ducts, and whatever is riding in that air, dust, pet hair, skin cells, settles along the way. Cold nights that average 25°F mean long runtimes, so the air moves more, not less.
Hamilton County has seen 16 winter storms and 169 damaging wind events over the past ten years. Storms like that knock out power, and Ohio households went without it for a day or more at a rate of 18% last year. When the furnace stops and starts back up, or sits off for hours in a cold house, ducts can pull in more of what settles on floors and in closets nearby. Over enough winters, that buildup narrows the space air moves through and gives the blower more to push against.

- How often should air ducts be cleaned?
- There is no set schedule that fits every home. Most homes do not need it on a calendar at all. Pets, a recent remodel, or someone with allergies in the house are reasons to look at it sooner. If you can see dust coming out of the vents or building up fast on furniture, that is a sign to have a contractor check the ducts rather than wait.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, not just as routine upkeep. If rodents, water damage, mold, or a lot of construction dust got into the system, cleaning the ducts makes sense. It will not lower your heating bills and it will not fix an allergy on its own, so a contractor should tell you what they find in your ducts before you pay for the job.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system to pull air through it, then uses brushes or air whips to knock dust and debris off the inside of the duct walls so it gets pulled into the vacuum instead of back into your house. They will also clean the supply and return grilles, and often the coil and blower housing on the furnace since those collect dust too. A good contractor shows you the ducts before and after, either with a camera or by opening one so you can see it yourself.
