Seven months of heating pushes a lot of air through your ducts
Your furnace runs October through April here, close to seven months a year. Each time it starts, air pulls through the return duct and pushes back out through the supply side, carrying along whatever dust has settled since the last cycle. On nights that average 26 degrees, the furnace is cycling on and off often just to hold the temperature, and every cycle is another pass of air through the same ductwork.
The county has also had 10 winter storms and 60 damaging wind events over the past ten years, and storms like these knock out power. When a furnace shuts off and starts back up, the restart stirs up whatever has settled in the ducts and sends it back into the air moving through the house.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. If anyone in the house has allergies, or you have pets shedding into the return vents, you will want to clean them more often than a house without either. After any work that opens up the ducts, like a furnace replacement, it is worth having them cleaned once that work is done. A contractor can look at what is actually in your ducts and tell you whether it is time.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If you can see dust blowing out of the vents, or there is visible buildup when you pull a vent cover off, cleaning will help your air quality and may let your furnace and air conditioner move air more easily. If your ducts look clean and nobody in the house has breathing issues, you may not need it yet. A contractor can look inside the ducts with a camera and tell you what is actually there before you decide.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust, debris, and buildup along the inside of the ducts, then pulls it all out through the vacuum. This usually covers the supply and return ducts, the vents themselves, and sometimes the coil area near the furnace or air handler. The furnace filter gets replaced separately since that is what actually filters the air, the ducts just carry it.
