common causes of standing water in the aC drain pan

  • Clogged Drain Pipes
  • Frozen Evaporator Coils
  • Improper AC System Installation

clogged AC Drain pipe

The most frequent cause of standing water in the drain pan is a clogged AC drain pipe. As air moves over the evaporator coils in your air conditioner, it cools and leaves behind humidity as condensation. This condensation drips into the condensate pan and exits through the drain line.

Besides water, the air passing over the evaporator coils also leaves dust and dirt behind. When this dirt mixes with the condensation, it can flow down the drain line and create a clog. While this is a relatively simple issue, it's best to have one of our skilled technicians handle the repair to ensure it’s done correctly and check for any other potential problems.

Frozen evaporator coil

A frozen evaporator coil can cause dripping water, resulting in moisture in the HVAC drip pan. This issue is commonly due to low refrigerant levels, often indicating a refrigerant leak within the cooling system. Our HVAC technicians can identify and repair leaks, then recharge your refrigerant to restore your system.

improper installation of your air conditioning system

Improper installation can lead to incorrect angling of the drain pan, causing water to pool. The drain outlet should be at the lower end of the pan to allow proper drainage. Additionally, the drain pan needs stable supports to prevent sagging, which can cause water to accumulate.
