One of the most common questions we get is: "How often should I have my air ducts cleaned?" The honest answer is: it depends. Here's what the EPA, NADCA, and our experience in Colorado Springs homes tells us.

The Standard Recommendation: Every 3–5 Years

Under normal conditions — no pets, no smokers, no recent renovations, no water damage — the EPA and NADCA (National Air Duct Cleaners Association) recommend air duct cleaning every 3–5 years. Colorado Springs' dry, dusty climate may push this toward the 3-year end of the range.

Clean Sooner If You Have:

• Pets that shed — pet dander accumulates rapidly in ductwork
• Allergies or asthma — more frequent cleaning reduces allergen load
• Recent water damage or flooding — mold can grow in ducts after moisture intrusion
• Recent home renovation — construction dust contaminates ductwork
• Visible mold growth in or around vents
• Pest infestation — rodent droppings and debris in ducts require immediate cleaning
• New home purchase — you don't know the history of the previous owners

Signs Your Ducts Need Cleaning Now

• Visible dust blowing from vents when HVAC runs
• Musty or moldy smell when HVAC is running
• Excessive dust accumulation on furniture despite regular cleaning
• Allergy symptoms that worsen when HVAC is running
• Visible debris or buildup at vent covers
