Seven months of forced air, moving through the same ducts
Your furnace runs October through April here, seven months of the year. Every one of those months it's pulling air through the return and pushing it back out through every vent in the house. Whatever is riding in that air settles in the ducts a little more each week.
On winter nights averaging 31°F, the furnace cycles on and off to hold the house at temperature, and each cycle stirs loose whatever has settled and sends it back into the rooms. Seven months of that is enough for it to build up in the runs.
- 7 months

- How often should air ducts be cleaned?
- Most homes do fine with duct cleaning every few years rather than on a set yearly schedule. If anyone in the house has allergies, or you have just finished a remodel that put drywall dust into the return vents, do it sooner. Homes with pets or a smoker should also lean toward cleaning more often. A contractor can look at what is actually collecting in your ducts and tell you whether it is time.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, not just as a routine habit. If you see dust building up fast around the vents, or notice a musty smell when the furnace or air conditioner kicks on, cleaning the ducts can fix that. It will not lower your heating or cooling bills, and it will not fix a duct that is leaking air into the attic or crawlspace. A contractor can look at the ductwork and tell you whether cleaning solves the problem you are having or whether something else is going on.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock dust and debris loose from inside the duct walls, then pulls it out through the vacuum before it can resettle. Every supply and return vent in the house gets cleaned this way, along with the main trunk lines. The furnace or air handler itself usually gets attention too, since dust collects on the blower and coil. A new filter at the end of the job keeps what is left from just building back up.
