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

Your furnace runs October through May here. On the nights that average 13°F, it runs long and often, and every bit of that air moves through the same ductwork. Dust, pet hair, and the fine debris that settles in a house all get pulled in and pushed back out, load after load, for eight months straight.

That is a lot of runs for dust to build up in the bends and joints of your duct system, where it stays until something moves it back out into the rooms you're heating.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home, but a few signs point to it being time. Dust kicking out of the vents when the furnace kicks on, a musty smell, or anyone in the house with allergies acting up are all reasons to have a contractor take a look. Homes with pets tend to need it more often, since pet hair and dander build up in the ductwork faster. A contractor can look at your system and tell you what it needs.
Is air duct cleaning worth it?
It depends on what is going on in your ducts right now. Homes here run the furnace from October through May, so if the ducts are carrying dust or buildup, that air is moving through the house for eight months straight. If you can see dust around the vents or notice more dust settling in the house than usual, clearing the ducts is worth doing. It will not fix uneven heating from a leaking or poorly sealed duct, that is a separate problem worth asking a contractor about.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen dust and debris from inside the duct walls, then pulls it out through the vacuum. The supply and return vents and the main trunk lines get cleaned, and sometimes the coil and blower compartment too. A contractor can walk through what your specific system needs before starting.
