Eight months of heat moving through the same ducts
Your furnace runs October through May here, eight months of the year. Winter nights average 22°F from December through February, so the furnace is cycling on through most of the night, every night, pushing air through the same ductwork over and over. Whatever settles in that ductwork gets carried into every room each time it runs.
This county has seen 107 winter storms and 222 damaging wind events over the past ten years. Wind that strong works dust and debris toward the seams and gaps in ductwork, and a hard freeze outside can force a furnace to run longer to keep up, moving even more air through ducts that have not been cleaned.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. A contractor can look inside the ducts and tell you whether there's enough dust or buildup to make cleaning worth doing now. If anyone in the house has allergies, or you've had a rodent problem or a musty smell coming through the vents, that's a reason to have them checked sooner rather than later. A recent remodel is another good reason, since drywall dust settles into the ductwork and stays there until it's cleaned out.
- Is air duct cleaning worth it?
- It depends on what's actually going on in your ducts. If you can see dust blowing out of the vents, or there's a musty smell when the furnace kicks on, cleaning solves a real problem. If the ducts look and smell fine, cleaning is more about upkeep than fixing anything. A contractor can look inside the ductwork and tell you what's actually in there before you decide.
- 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. The supply and return vents get cleaned too, along with the grilles that cover them. On most jobs the furnace or air handler gets a look as well, since dust in the ducts usually means dust in the blower and coil too.
