What is the minimum recommended interval for drainage pan inspection?

Explanation:
Inspecting the drainage pan is part of a regular, once-a-year HVAC maintenance routine. The pan catches condensate from the cooling coil, and if the drain becomes clogged, the pan rusts or leaks, or the condensate pump fails, standing water can cause water damage and mold. A yearly check helps ensure the pan is intact, properly positioned, free of debris, and that the drain line and pump are functioning. This aligns with the minimum guideline from BPI 6.3. More frequent inspections are only needed if there are known problems or unusually high humidity, but the baseline interval is annually.
