Air duct cleaning might not be on your seasonal to-do list, but it plays a major role in keeping your home comfortable, energy-efficient, and safe. This is especially true during long Minnesota winters and allergy-filled springs. If you’re wondering how often you should clean your air ducts, you’re not alone.
At Gray Duct Heating, Cooling & Air Duct Cleaning, we’re often asked about the right schedule for duct cleaning. The answer depends on several factors, including your home’s age, your family’s health, and your HVAC habits.
General Guideline: Every 3 to 5 Years
Most homes benefit from professional air duct cleaning every 3 to 5 years. This recommendation comes from the National Air Duct Cleaners Association (NADCA), and it assumes your HVAC system is well maintained and your filters are changed regularly.
Ducts collect dust, pollen, pet dander, and even mold spores over time. Cleaning them helps improve your indoor air quality and keeps your heating and cooling system running smoothly.
Signs You Need Air Duct Cleaning Sooner
In some cases, waiting three years might be too long. Here are signs that it’s time to schedule service now:
- Dust buildup around your vents or on furniture shortly after cleaning
- Musty or moldy smells when the HVAC runs
- Visible mold growth inside ductwork or HVAC components
- Recent remodeling or construction work
- Increased allergy or asthma symptoms
- Pets that shed heavily
- Tobacco smoke in the home
If you notice any of these issues, it’s worth having your ducts inspected. You may also benefit from system fogging to eliminate odors and microbial growth.
Factors That Affect Cleaning Frequency
Some homes need duct cleaning more often. Your schedule might depend on:
- Your HVAC system’s age and condition
- Type and quality of filters used, and how often they’re changed
- Whether your ductwork is sealed and insulated
- If you use a ductless system, which doesn’t require traditional duct cleaning but still needs regular care
Routine maintenance and regular filter changes can extend the time between cleanings.
