How often should I have my air ducts cleaned?

Have air ducts cleaned every three to five years, or sooner if you have pets, smokers, recent renovations, or visible mold growth. Signs you need cleaning include excessive dust, musty odors when the HVAC runs, or family members with unexplained allergy symptoms.

Why It Matters

Clean air ducts improve indoor air quality, reduce circulating dust, and help your HVAC system operate efficiently.
