Nine months of heating pushes a lot of air through your ducts
Your furnace runs from September through May here, and on winter nights that average 9°F it cycles on and off most of the night to keep up. Every one of those cycles pushes air through the same ductwork, and whatever is sitting in there, dust, pet hair, drywall dust from any repairs, gets stirred up and carried into the rooms you live in.
Blaine also sees its share of rough weather, with 28 winter storms and 40 damaging wind events recorded across Anoka County over the past ten years. Power interruptions that come with storms like these can shut a system down mid-cycle, and when it restarts, it pulls that settled dust back into motion again. Over nine months of heating, that buildup thickens, and the air moving through your home carries more of it than it should.

- How often should air ducts be cleaned?
- Most homes do fine having it done every few years rather than on any fixed yearly schedule. If anyone in the house has allergies, or you've had renovation work that left dust behind, sooner makes sense. Pets and recent construction both add more debris to the system, so those homes tend to need it more often.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like visible dust coming from the vents, a musty smell when the furnace runs, or renovation debris in the system. It won't lower your heating bill or fix a furnace problem on its own. The value is cleaner air moving through the house, not energy savings.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system and uses brushes or air tools to knock loose dust and debris from inside the ducts, then pulls it out through that vacuum connection. Each supply and return vent gets opened and cleaned this way. The furnace or air handler itself, including the blower and coil, usually gets cleaned as part of the same visit since it shares the same air path.
