Nine months of heating leaves a lot behind in your ducts

Your furnace runs September through May here, nine months of the year. On nights that average 18°F, it cycles on and off again and again to keep up. Every time it runs, air moves through the ducts, and whatever is riding in that air settles along the way.

Minidoka County has seen 28 winter storms and 42 damaging wind events over the past ten years. Wind like that pushes dust and debris in around doors, windows, and vents, and it ends up pulled into your system and carried through the ductwork. Over nine months of steady use, that buildup lines the ducts and gets thrown back into the rooms you're heating.

How often should air ducts be cleaned?
There's no fixed schedule that fits every house. Homes with pets, a smoker, or someone with allergies pull more into the return air and need it more often. If a room never gets warm even when the furnace is running fine, or dust builds up fast after a cleaning, that's worth a look sooner rather than later.
Is air duct cleaning worth it?
It's worth it when there's a real reason for it, like dust that keeps coming back right after you clean, a musty smell when the air handler kicks on, or work that opened up the ducts, like a remodel. It won't lower your heating bill or fix a furnace that's not heating right. If nobody in the house has allergy trouble and the air coming out looks and smells fine, it's not something you need to chase on a schedule.
What does air duct cleaning involve?
A contractor connects a vacuum to the duct system and uses brushes or air tools to knock dust and debris loose from the inside of the ducts, then pulls it out through the vacuum. They'll open the supply and return vents to reach the branch lines, and check the coil and blower compartment since dust collects there too. The furnace filter gets replaced or cleaned as part of the job, since a clogged filter undoes a lot of what the cleaning accomplishes.
