The NADCA Recommendation

The National Air Duct Cleaners Association recommends every 3–5 years for most residential systems.

Salt aerosols, sand, marine humidity, and frequent open-window living all accelerate duct contamination here.

Pets, allergies, asthma, recent renovations, smokers in the home, or post-water-damage all warrant a shorter interval.

Annual maintenance keeps the system efficient between full duct services.

Same-day appointments. Honest pricing. 24/7 emergency service.
