Eight months of heating pulls the buildup through your ducts
Your furnace runs October through May here. That's air moving through the same ductwork for most of the year, carrying dust and everything else in the house along with it. Most of it settles inside the duct walls instead of blowing back out through the vents.
Hempstead has seen 37 winter storms and 143 damaging wind events over the past ten years, and storms like that knock out power. When the furnace shuts down in a cold snap and starts back up, the air inside the ducts sits still and anything loose in there settles more. Winter nights here average 28°F from December through February, so that furnace runs hard and often, and what's built up inside the ducts keeps moving through your house.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, so the honest answer is to clean them when there's a reason to. A renovation, water damage inside the ducts, or dust visibly blowing out of the vents when the system starts are all reasons to have them looked at. Pets or smokers in the house tend to make it worth checking sooner rather than later. A contractor can look at the ducts and tell you whether they actually need it.
- Is air duct cleaning worth it?
- It's worth it when there's a real problem behind it, not just as something to do on a schedule. Visible mold inside the ducts, signs of rodents, or heavy dust coming through the vents are all reasons cleaning will actually help. Without one of those, cleaning the ducts won't make the air noticeably cleaner or lower your heating bills. A contractor should look first and tell you what they find before you pay for the job.
- What does air duct cleaning involve?
- A contractor hooks a vacuum system to the ductwork and uses brushes or air whips to loosen dust and debris from inside, then pulls it out through the vacuum. The supply and return vents get cleaned along with the grilles covering them. On most jobs the furnace or air handler gets cleaned too, since all the air passes through it before it ever reaches the ducts.
