What does NADCA recommend regarding filter maintenance?

The recommendation from the National Air Duct Cleaners Association (NADCA) for filter maintenance focuses on the necessity of regular replacement of filters based on their usage and type. This approach acknowledges that different environments and systems can have varying demands on filters, affecting how quickly they become clogged with dust, debris, and other contaminants.

This practice ensures that the HVAC system operates efficiently, maintains good indoor air quality, and prevents undue strain on the system that could lead to higher energy costs or equipment failure. Regularly assessing the condition of filters, along with adhering to a replacement schedule that considers the specific conditions in which they operate, is essential for effective HVAC performance and longevity.
