Seven months of heating means seven months of buildup moving through your ducts

Your furnace runs October through April here, seven months of the year. On nights that average 28°F through the coldest stretch, it runs long and often to keep up. Every one of those runs pushes air through the same ducts, and dust settles in them a little more each week.

Most homes in the county are not single-family houses, and most people here rent rather than own. Whoever is in the home breathing that air, the buildup in the ducts works the same way. The longer the heating season, the more it collects, and the more of it moves through the rooms each time the blower starts.

How often should air ducts be cleaned?
Most homes only need it every few years, not on any fixed schedule. If anyone in the house has allergies, or you have had a renovation or duct work done recently that left dust behind, it is worth doing sooner. Outside of that, let what you see at the vents be your guide.
Is air duct cleaning worth it?
It is worth it if your ducts actually have buildup in them, dust, debris, or signs of pests. It will not fix a heating or cooling problem on its own, and it will not lower your bills the way some claim. The real reason to do it is air quality, less dust circulating through the home and fewer allergens blowing out of the vents.
What does air duct cleaning involve?
A contractor inspects the ducts first, then uses brushes and a vacuum system to loosen and pull out the dust and debris inside. Every vent and return in the home gets cleaned, along with the main trunk lines. The furnace or air handler often gets a look too, since it connects directly to the same ductwork.
