Ten months of heating a year moves a lot of air through your ducts

Your furnace runs from September through June here, close to ten months a year. Every one of those months, air is moving through your ductwork, and whatever is riding in that air settles along the way. Coat by coat, dust and pet hair build up along the inside of the duct walls.

With winter nights averaging 19°F, the furnace is working hardest during the very months when that buildup is collecting. As the coating thickens, it narrows the path air has to travel, and the furnace has to push harder to move the same amount of heat through the house.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home, so the honest answer is that it depends on what's going on inside the ducts. If anyone in the house has allergies, or you've had a remodel or other work that left dust behind, that's a reason to do it sooner rather than wait. Homes with pets or a recent rodent problem should also move it up. Outside of those situations, a contractor can look at the ducts and tell you whether they actually need it.
Is air duct cleaning worth it?
It's worth it if your ducts actually have a buildup problem, not just as routine maintenance. Look inside a vent cover with a flashlight. If you see thick dust or debris, cleaning will help air move through the system the way it should and can cut down on dust settling around the house. If the ducts look fine, cleaning them isn't going to change much.
What does air duct cleaning involve?
A contractor connects a vacuum to the duct system to create suction, then uses brushes or air tools to knock loose dust and debris from inside the ducts so it gets pulled out rather than blown into the house. This covers the supply and return ducts, and usually the grilles and registers too. Some contractors also clean the blower compartment, since dust there gets pulled straight into the airflow.
