Seven months of heat pushes dust through every duct in the house
Your furnace runs October through April here, close to seven months of the year. Each time it starts, air moves through the ducts and carries along whatever has settled inside since the last cycle. Nights average 27°F through the coldest stretch of winter, so the furnace cycles on and off many times a day, and each cycle is another pass of air through the same dust.
Silver City also gets its share of wind, 46 damaging wind events over the past ten years along with 11 winter storms. Wind pushes dust into a house through any gap it can find, and that dust settles into the ducts along with everything else moving through them. Over enough winters, that buildup can block airflow to parts of the house and end up in the air the household breathes.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, so watch the ducts and vents instead of the calendar. If you can see dust building up at the vents, or you've had a repair that left debris behind, that's the signal to get them cleaned. Homes with pets or a recent renovation tend to need it sooner, since more gets pulled into the return air.
- Is air duct cleaning worth it?
- It depends on what's in your ducts right now. If you can see dust building up at the vents, or notice more of it settling on furniture than seems normal, cleaning will make a real difference. If nobody in the house has breathing trouble and the vents look clean, it's not something you need to chase.
- What does air duct cleaning involve?
- A contractor uses specialized tools to loosen dust and debris from inside the ductwork, then a vacuum system pulls it out before it can resettle. The supply and return vents get cleaned too, along with the grilles covering them. Some contractors also check the coil and blower while they're in there, since dust on those parts affects how well the system runs.
