Eight months of heating pushes a lot of air through those ducts

Your furnace runs from October through May here, close to eight months a year. Every cycle pushes air through the ductwork and into your rooms, and whatever has settled inside those ducts rides along with it. Dust, pet hair, and the fine debris that collects in a duct over months of use gets stirred up and circulated through the house each time the system starts.

Winter nights here average 21°F from December through February, so the furnace is cycling on and off through the coldest part of the night, not just running steady. Each cycle is another push of air carrying whatever is built up in the ducts back into the rooms you're sitting in.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home. Clean sooner if you see mold inside the ducts, if pests have gotten in, or if someone in the house has allergies that flare up when the heat or air conditioning runs. A contractor can look inside the ducts and tell you whether they need attention now or can wait.
Is air duct cleaning worth it?
It depends on what's going on with your ducts. If you can see dust building up around your vents, if a room never seems to heat or cool right, or if you've had rodents or a leak in the ductwork, cleaning solves a real problem. If your system is running fine and nobody in the house has breathing issues, there's less to gain from it. A contractor can look at your ducts and tell you whether cleaning will actually change anything.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork, then uses brushes or air tools to knock loose the dust and debris built up on the inside walls of the ducts before pulling it out through the vacuum. Registers and grilles come off so every duct can be reached, and the furnace or air handler itself usually gets cleaned along with the ducts since air moves through both. The job covers the supply and return ducts throughout the house, not just the ones you can see.
