Your furnace runs nearly year round here

Homes in Johnson County need heat from September through June. That is ten months of the furnace cycling on and off, pushing air through the same ducts night after night. On winter nights averaging 14°F, it runs long and hard to keep up.

That much runtime pulls dust and debris through the ductwork and settles it along the seams and turns. Wind events are common here too, and a house that gets buttoned up tight against the cold and wind also traps whatever is circulating in that air. Over ten months, it builds up.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home, so watch for the signs instead. Dust building back up fast around your vents, a musty smell when the furnace kicks on, or someone in the house with allergies that ease up when they're away are all reasons to have them checked. Homes here run heat from September through June, so the ducts are moving air most of the year, which means dust and debris have a lot of time to collect. A contractor can look inside the ducts and tell you whether cleaning makes sense now or can wait.
Is air duct cleaning worth it?
It's worth it if you can see dust collecting fast around your vents, a room never feels fully clean, or someone in the house has allergy symptoms that ease up when they leave home. It won't fix a heating or cooling problem by itself. A contractor can look at your ducts and tell you whether cleaning will help or whether something else is going on.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork and uses brushes or compressed air tools to loosen dust and debris from the inside of the duct walls, then pulls it out through the vacuum. Every supply and return vent gets opened and cleaned, and the furnace blower and coil are often cleaned at the same time since air moves through them too. The work is done from inside the house, so nothing needs to come out of the walls.
