If someone asked you when your last oil change was, you’d probably know the answer. But if they asked when you last cleaned your air ducts, would you? For many Milwaukee homeowners, ductwork is one of those “out of sight, out of mind” parts of the home, until something goes wrong.
Yet what you can’t see inside your air ducts can affect how you feel, how much you spend on heating and cooling, and even how long your HVAC system lasts. So, if your home’s air feels stale, your allergies are acting up, or your energy bills are creeping higher—your ducts could be to blame.
Let’s talk about what might be hiding in your ducts, how it impacts your comfort, and why a proper cleaning may be one of the smartest home maintenances moves you can make before winter hits.
What Builds Up in Your Ducts?
Air ducts are the silent carriers of your home’s comfort. But over time, they collect more than just airflow. Some of the most common culprits found in dirty ductwork include:
- Dust and pet dander
- Mold and mildew spores
- Pollen and allergens
- Construction debris or pest remnants
In homes with pets, smokers, or recent renovations, these contaminants can build up quickly. When the furnace or AC kicks on, they get circulated throughout your home—right into the air you breathe.
Why Dirty Ducts Matter More Than You Think
1. Indoor Air Quality Drops
According to the EPA, indoor air can be 2 to 5 times more polluted than outdoor air. Dirty ducts only make this worse by continuously cycling allergens and irritants through your living space. This can especially impact people with asthma, allergies, or respiratory conditions.
2. System Efficiency Suffers
When your ductwork is coated in dust and grime, your heating and cooling system has to work harder to move air. This added strain leads to higher energy bills and shortened equipment life. Clean ducts mean smoother airflow and more efficient heating and cooling.
3. You Might Smell (or Hear) It
Musty odors, rattling, or inconsistent airflow are all signs of something lurking in your ducts. Whether it’s trapped moisture, debris, or even rodent remnants, these are symptoms of a system that needs attention.
How Often Should You Clean Your Air Ducts?
While duct cleaning isn’t something you need every year, the National Air Duct Cleaners Association (NADCA) recommends it every 3–5 years, or sooner if:
- You’ve recently renovated
- You notice visible dust or black debris near vents
- Someone in the home has severe allergies or asthma
- You’re moving into a previously occupied home
- There’s a history of water damage, mold, or pests
In Milwaukee, where we spend long stretches of the year indoors due to cold weather, keeping indoor air clean is a matter of health—not just comfort.

Why It Pays to Do It Before Winter
Milwaukee winters mean our homes stay closed tight for months at a time. That means the same air is being circulated, day after day through your ducts. If those ducts are dirty, you’re just moving pollutants in a loop.
Cleaning your ducts in the fall ensures you’re starting the season with clean air, better efficiency, and fewer unexpected HVAC problems in the deadof winter.
