Seven months of heating moves a lot of air through those ducts

Your furnace runs October through April in Hamilton, close to seven months a year. Every time it kicks on, the blower pushes air through the same runs and boots, and whatever is in that air settles out along the way. Dust, pet hair, anything airborne in the house, it moves through the ductwork and some of it stays there.

By spring those ducts have had a full winter of that. What has built up inside does not stay put. Each time the blower runs, it stirs some of that back into the air moving through the house.

How often should air ducts be cleaned?
There is no fixed schedule that fits every house. If anyone in the house has allergies, or a duct was recently opened up for repair work, cleaning sooner makes sense. Homes with pets or a recent renovation tend to build up dust faster than others. If you cannot remember the last time it was done, that is a sign it is due.
Is air duct cleaning worth it?
It depends on what you are hoping it fixes. If dust keeps settling back within a day or two of cleaning your house, or you can see debris at the vent openings, clearing the ducts out will help with that. It will not lower your heating bill or fix a furnace that is running poorly, those come down to the equipment itself, not what is inside the ducts. Where it earns its keep is air quality and knocking down the dust load in a house that is holding onto a lot of it.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose the dust and debris built up inside, then pulls it all out through the vacuum. Each supply and return vent gets opened and cleaned, along with the main trunk lines. If your system has a coil or blower that is reachable, those get cleaned too since they collect the same dust the ducts do. A contractor can walk through what your specific setup needs before starting.
