The primary AC drip pan is typically located underneath the indoor evaporator coils.
Air conditioning units utilize drip pans (also known as drain pans or condensate pans) to collect the condensation that forms on the evaporator coils as the system cools the air. This collected water is then directed away from the unit, usually through a drain line. Understanding the location of these pans is crucial for maintenance and identifying potential leaks.
Based on common AC system designs:
-
Primary Drain Pan: As highlighted in the reference, the main condensate pan is situated directly underneath the indoor evaporator coils. This is where the majority of condensation drips. This pan is often integrated tightly with the coil assembly and, as the reference mentions, can be welded to the evaporator coil, potentially making replacement more challenging.
-
Auxiliary or Backup Drain Pan: Many systems also include a secondary or auxiliary drain pan. This pan is located below the primary pan and main drain line. Its purpose is to catch any overflow water if the primary pan or drain line becomes clogged.
Here's a quick breakdown:
- Main Collection Point: The primary pan sits directly below the part of the AC that gets cold and creates water – the evaporator coil.
- Safety Net: A backup pan is usually placed below the primary setup as a safeguard against leaks.
Ensuring these pans are clean and functional is vital for preventing water damage to your home. A clogged drain pan or drain line is a common cause of AC leaks.
