Seven months of heating pushes a lot of air through your ducts

Your furnace runs October through April here, close to seven months a year. Every time it kicks on, air moves through the ductwork, and whatever is sitting in those ducts moves with it. Dust, pet hair, and anything that settled in over the summer gets stirred up and pushed into the rooms you live in.

Camden County has seen 57 damaging wind events and 7 winter storms over the past ten years. Wind like that drives dust and debris into attics, crawlspaces, and anywhere ductwork runs. That debris finds its way into the system and stays there until it is cleaned out or it keeps circulating through the house all winter.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home, but a few things point to when it is time. Dust coming back out of the vents right after you clean, a musty smell when the furnace kicks on, or a new pet or renovation in the house are all signs. Homes here run the furnace October through April, seven months a year, so ducts that need attention will show it during that stretch. A contractor can look at your ductwork and tell you whether it needs cleaning now or can wait.
Is air duct cleaning worth it?
It is worth it when there is a real reason behind it, like dust coming out of the vents, a musty smell when the furnace or air conditioner runs, or someone in the house with allergies that flare up indoors. It will not lower your heating bill or fix a system that is running poorly. Those problems come from other causes. A contractor can look at the ducts and tell you whether cleaning will actually help your situation.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to knock dust and debris loose from inside the ducts so it can be pulled out. Every supply and return line gets checked, along with the grilles and registers where dust collects. The furnace or air handler itself usually gets a look too, since debris can build up around the blower and coil.
