Eight months of heating moves a lot of air through your ducts
Your furnace runs October through May here. That's most of the year your ducts are carrying air, and every pass carries some dust and pet hair into the runs and bends where airflow is weak. It settles there and stays.
On nights that average 17°F, the furnace cycles on and off for hours to hold the temperature, and each cycle pushes more air through ducts that already have buildup sitting in them. That buildup doesn't go anywhere on its own. It gets stirred up and blown into the rooms every time the system runs.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. If anyone in the house has allergies, or you have had rodents, water damage, or a renovation that stirred up dust into the system, that is a reason to have them cleaned sooner rather than later. Pets and smoking also add to what builds up inside the ducts over time. A contractor can look inside the ducts and tell you what condition they are in rather than going by a calendar.
- Is air duct cleaning worth it?
- It depends on what is actually in the ducts. If you can see dust blowing out of the vents, or there is visible mold, pest droppings, or debris left over from construction work, cleaning them is worth doing. If the ducts are just doing their job quietly and nobody in the house has breathing trouble, there may be nothing to gain. A contractor can inspect the ductwork and tell you honestly whether cleaning will make a difference in your case.
- What does air duct cleaning involve?
- A contractor connects a high-powered vacuum to the duct system to create negative pressure, then uses brushes or air tools to knock dust and debris loose from inside the ducts so it gets pulled into the vacuum instead of blown into your rooms. This usually covers the supply and return ducts, the grilles and registers, and sometimes the coil and blower housing at the furnace or air handler. The filter is not part of the duct cleaning itself. It gets replaced separately, since its job is to catch what the ducts carry.
