Ten months of heat means ten months of dust moving through your ducts

Your furnace runs September through June here, ten months of the year. That is ten months of air pulled through the return, pushed through the ducts, and blown out into your rooms. Every pass carries a little more dust and lays it down again on the floors and furniture it just passed over.

Winter nights average 21°F from December through February, so the furnace is not just running, it is running hard and often through the coldest stretch. The more it runs, the more it moves through that ductwork, and the more builds up inside it.

10 months: September through June, your furnace pushes air through your ducts
2 months: July through August, your air conditioner does the same

How often should air ducts be cleaned?: There is no fixed schedule that fits every home. Signs like dust coming from the vents, a musty smell when the furnace runs, or dust settling again right after you clean the house are better guides than a calendar date. Since heat runs here from September through June, the ducts are moving air most of the year, so it is worth checking them whenever something seems off rather than waiting.
Is air duct cleaning worth it?: It depends on what is going on in your ducts. If they are visibly dusty, if you have had rodents or a leak, or if dust seems to settle again right after you clean the house, cleaning them makes a real difference. If none of that applies, the ducts are probably not the problem and cleaning them will not change much.
What does air duct cleaning involve?: A contractor uses a vacuum system attached to the ductwork to pull loose dust and debris out through the vents, while agitation tools loosen what has stuck to the inside walls. Registers and grilles get cleaned along with the ducts themselves. The furnace or air handler is usually cleaned at the same time, since air moves through it on the way to the ducts.
