Your HVAC system works hard year-round to keep your home comfortable, but when was the last time you thought about your air ducts? Over time, dust, debris, mold, and even pests can build up inside your ductwork, affecting both your system's efficiency and the air you breathe. So, how do you know if it's time for a duct cleaning? Here are the key signs to watch for:

1. Visible Dust and Debris
If you notice dust blowing from the vents when your system turns on, or if you see dirt around vent covers, it could mean your ducts are due for a cleaning.
2. Increased Allergy Symptoms
Are you or your family members experiencing more sneezing, coughing, or allergy flare-ups at home? Dirty ducts can circulate allergens like pollen, dust mites, and pet dander throughout your living space.
3. Musty or Unpleasant Odors
Persistent musty smells when your HVAC is running may point to mold or mildew inside your ducts. This not only affects comfort but could pose health risks.
4. Inconsistent Airflow or Poor Efficiency
If some rooms feel stuffy or aren’t heating/cooling properly, blockages or buildup in your ducts could be to blame. Clean ducts help your system distribute air more evenly and efficiently.
5. Rodent or Insect Infestations
If you’ve dealt with pests in the past, there's a chance they left behind droppings, nests, or remains inside the ducts. A thorough cleaning can eliminate these hazards and restore clean airflow.
6. It’s Been Several Years
Experts generally recommend duct cleaning every 3 to 5 years, or more often if you have pets, allergies, or have recently renovated your home.
