A properly functioning air conditioning system produces condensation that collects in a drip pan. Ideally, this pan should contain a minimal amount of standing water. While some moisture is expected due to ongoing condensation, a significant accumulation suggests a problem, such as a clogged drain line.
Maintaining a near-empty drip pan is critical for several reasons. Excess water can overflow, causing property damage. Standing water also creates a breeding ground for mold and mildew, leading to unpleasant odors and potential health concerns. Historically, drip pans were simpler, often relying solely on gravity for drainage. Modern systems frequently incorporate features like float switches and condensate pumps to improve drainage and prevent overflow. The shift towards these advanced features underscores the recognized importance of efficient condensate management.
