Eight months of heat pushes a lot of air through your ducts

Your furnace runs October through May here, close to eight months of the year. On the cold nights, the kind that average 20°F in December through February, it's cycling on and off for hours to keep up, and every cycle pushes air through the same ductwork. Dust, pet hair and whatever gets tracked into the house rides along with that air and settles in the bends and joints over time.

Peoria County has also seen its share of wind, 147 damaging wind events over the past ten years plus 12 winter storms. Storms like that can force outside air, dust and debris into ducts through gaps around vents or damaged sections, and with 16% of Illinois households losing power for 24 hours or more last year, systems sitting idle during an outage collect settled dust that gets stirred up again the moment the furnace kicks back on.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home. If you can see dust building up around the vents, or the air coming out smells stale or musty, that is your sign to have it done. Homes with pets, a recent renovation, or someone with allergies often need it sooner than homes without.
Is air duct cleaning worth it?
It helps when there is a real reason for it, like visible dust at the vents, a musty smell, or work that was just done on the ducts themselves. It will not lower your heating bills or fix a furnace that is running poorly. If nobody in the house has allergy trouble and the vents look clean, you can likely wait.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork, then uses brushes or compressed air tools to knock loose the dust and debris built up inside so it can be pulled out through the vacuum. The supply and return vents get cleaned too, along with the coil and blower housing where dust tends to collect. The furnace filter still needs its own regular changes after the cleaning is done.
