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

Your furnace runs September through May here, nine months of the year. Every one of those months, air moves through your ducts and out into the rooms, and whatever is riding in that air settles along the way. Nine months is a long stretch for dust to build up on the inside of sheet metal that never gets looked at.

Winter nights averaging 15°F mean the furnace runs long and often to keep up. More runtime means more air pushed through, and more of what is already sitting in the ducts gets stirred up and blown into the house. A duct system that has not been cleaned in years is working harder than it should, and sending more of that buildup into the rooms you spend time in.

How often should air ducts be cleaned?
There's no fixed schedule that fits every house. If anyone in the house has allergies, you have pets, or you just finished a remodel, dust and debris build up faster and the ducts are worth checking sooner. A contractor can look at what's actually in there and tell you whether it needs cleaning now or can wait.
Is air duct cleaning worth it?
It's worth it when there's a real reason behind it, like dust coming through the vents, a musty smell when the furnace runs, or work done on the house that left debris in the system. It won't lower your heating bills or fix an allergy on its own. What it does is clear out what's actually collected in the ducts so the air moving through your house isn't carrying it.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork and uses brushes or air tools to loosen dust and debris, then pulls it out through the vacuum before it can resettle. Every supply and return vent gets cleaned, along with the main trunk lines that run to your furnace. The furnace itself, including the blower and coil, usually gets attention too since that's where the air passes through on every cycle.
