Eight months of heating pushes dust through your ducts
Your furnace runs October through May here, eight months out of the year. Every time it cycles on, air moves through the same runs of ductwork and stirs up whatever has settled inside them. Dust and pet hair build up in there and get pushed through the house again and again over a heating season this long.
Broomfield has also logged 60 damaging wind events over the past ten years. Wind that strong works dust and debris in around the house, and a furnace running eight months a year keeps pulling it through the ducts and putting it back into the air you breathe. Dirty ducts also make your furnace work harder to push air through them, which is one more strain on a system that already runs most of the year here.

- How often should air ducts be cleaned?
- Most homes do fine having their ducts cleaned every few years rather than on any fixed yearly schedule. If anyone in the house has allergies, or you've had a renovation, water leak, or pest problem, it's worth doing sooner. Ducts that run for eight months of heating here also collect more dust than ducts that sit idle most of the year, so homes in Broomfield tend to need it sooner rather than later.
- Is air duct cleaning worth it?
- It depends on why you're considering it. If you're seeing dust building up fast around vents, or you can see debris when you look into a duct, cleaning solves a real problem. If you're doing it hoping to cut energy bills or fix an allergy that isn't duct-related, it likely won't deliver what you're expecting. A contractor can look at your ducts and tell you honestly whether cleaning will help your specific situation.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to loosen dust and debris along the way, then pulls it out through the vacuum. Registers and grilles usually come off so every branch can be reached. The furnace or air handler often gets cleaned at the same time, since it's part of the same air path. Afterward, the contractor should seal everything back up so no dust escapes into the house before the job is done.
