Nine months of heat pushes a lot of air through those ducts
Your ducts run from September through May here, close to nine months of the year. That is a lot of hours moving air through the same runs, and dust settles in them the whole time.
Maine loses power often, 54% of households went at least a day without it last year, and the county has seen 95 winter storms and 93 damaging wind events over the past ten years. Furnaces and heat pumps shut down and restart through all of that, and every restart stirs up what has settled in the ducts and pushes it back into the house.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, so a contractor should look inside the ducts before you commit to a timeline. Homes here run the furnace September through May, nine months a year, so dust and pet hair have more months to move through the system than in places with a shorter heating season. If anyone in the house has allergies or you have pets, that's worth mentioning when a contractor takes a look.
- Is air duct cleaning worth it?
- It depends on what's actually going on in the ducts right now. If you're seeing dust coming out of the vents, or someone in the house has allergy symptoms that ease up when they're not home, cleaning will likely help. If the ducts look fine and nobody's having breathing problems, it's not something you need to do on a fixed schedule just to be safe. A contractor can check for real buildup before you spend money on it.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from inside the duct walls, then pulls it out through the vacuum. Each supply and return vent in the house gets cleaned this way, along with the main trunk lines. The furnace or air handler often gets a look too, since the blower and coil sit right in the airflow path and collect the same dust the ducts do.
