How Often Should I Clean My Air Ducts?

The Honest Answer: It Depends on Your Lifestyle.

We Don’t Believe in “One Size Fits All”

A Note from Owner James Green:

“If you ask Google, it will tell you to clean your ducts every 3 to 5 years. If you ask a ‘churn-and-burn’ cleaning company, they might harass you to do it every 2 years so they can make a quick buck.

Here is the truth:

Every home in Wisconsin is different. A retired couple living in a Brookfield condo with no pets may only need cleaning every 7 years. A family of five with two Golden Retrievers in a farmhouse in Muskego might need it every 3 years.

At Totally Clean, we operate by the ‘Grandma Rule.’ If we inspect your ducts and they don’t need cleaning, we will let you know. We want you as a customer for life, not just for a quick sale.”

The “Totally Clean” Frequency Formula

Instead of guessing, look at these three major factors to decide your schedule.

Factor 1: The “Fur Factor” (Pets)

Do you have shedding pets?

This is the single most significant driver of duct buildup. Pet hair and dander are sucked into your cold-air returns every day.

  • Our Recommendation: If you have multiple shedding dogs or cats, you are on the 3-year schedule. The hair creates a mat inside the return drops that restricts airflow to your furnace.

Factor 2: Your Location & Environment

What is outside your windows?

Wisconsin’s geography plays a significant role in indoor dust levels.

  • Rural Areas (Germantown, Muskego): If you live near active farm fields or gravel roads, dust and soil blow into your home every time a door opens.
  • New Construction (Oak Creek, Franklin): If your neighborhood is still being built, drywall dust and sawdust are constantly entering your home.
  • City Traffic: Homes near busy roads accumulate heavier, black soot dust.

Factor 3: Household Health

Do you suffer from allergies?

If someone in your home has asthma or severe seasonal allergies, “clean” might not be clean enough. Even a light layer of dust can trigger respiratory issues during our Closed Window Season.

  • Our Recommendation: Sensitive households often benefit from a cleaning every 3 to 4 years to keep the air pristine.

3 Signs You Need a Cleaning Now

Forget the calendar. If you see these signs, it’s time to call.

  1. The “Fuzzy Vent” Test: Look at your cold air return vents (the big grates). Is there a fuzzy layer of gray dust clinging to the slats? If the vent cover is dirty, the ductwork inside is 10x worse.
  2. The “New Home” Reset: Did you just buy a house? You are currently breathing the previous owner’s dead skin cells, pet dander, and odors. We highly recommend a Residential Air Duct Cleaning immediately after closing on a new home.
  3. Post-Renovation: Did you just remodel a kitchen or finish a basement? Drywall dust is fine, like flour, and can bypass standard furnace filters, coating your blower motor. This needs to be extracted immediately.

What About Other Services?

Some schedules are more rigid.

While duct cleaning is flexible, Dryer Vent Cleaning is not.

  • The Safety Rule: Due to fire risks, dryer vents should be inspected and cleaned every 12 to 18 months, regardless of your home’s size. Lint is flammable, and Wisconsin cottonwood seeds rapidly clog these vents in summer.
