How Often Should You Clean Your Air Ducts?
When duct cleaning is worth it — and when it isn't.
Every 3–5 years
Most homes benefit every 3–5 years, sooner with pets, allergies, smoking, or after renovations.
Don't skip the dryer vent
Dryer-vent lint buildup is a leading fire cause and hurts efficiency — clean it yearly.
Signs it's time
Visible dust from vents, musty smells, or worsening allergies are good prompts to schedule a cleaning.
