Payne Central air conditioner leaking at furnace or air handler
If your Payne air conditioner is leaking water at the furnace or air handler, check the evaporator coil and condensate drainage components first. The most common cause is an evaporator coil that is not tilted correctly toward the drain outlet, allowing condensation to miss the drain pan and overflow. If the air conditioner leaking water is coming from drain pan (also called a drip tray) without overflowing, the pan may be cracked and need replacement. A clogged condensate drain line or drain trap is less common, but it can back up water and cause an AC condensate leak or water under the furnace from AC operation. Turn off power to the unit before clearing a clog, and keep water away from electrical components. These repairs usually do not require EPA 608 certification, but refrigerant work or repairs inside the sealed system require a licensed HVAC technician. Use your Payne model number to find the exact replacement drain pan or other central air conditioner part for your system.
01 - Evaporator Coil Not Tilted Toward Drain
To help the condensate water to flow towards the drain outlet in the pan, most installers will tilt the evaportor coil slightly towards the drain hole. If the evaporator coil is not level, or tilted incorrectly, water will not flow to the drain hole and may overflow the pan.
Common
02 - Payne Central Air Conditioner Drip Tray
The evaporator is normally tilted slightly towards the drain hole to help the water to drain properly into the drip tray. If water is leaking from the drip tray but the tray is not overflowing, the drip tray is likely cracked and will need to be replaced.

03 - Payne Central Air Conditioner Drain Pan
The evaporator is normally tilted slightly towards the drain hole to help the water to drain properly into the drain pan. If water is leaking from the drain pan but the pan is not overflowing, the drain pan is likely cracked and will need to be replaced.
Common
04 - Clogged Drain Tube or Drain Trap
When the air conditioner is running, condensation forms on the evaporator coil and drips into a drain pan. From there the water is directed through a pipe with a trap to a floor drain or condensate pump. If the drain tube or trap gets clogged, the water will back up and overflow the drain pan. If water is leaking from the evaporator pan, it is likely the drain tube or trap is clogged and will need to be cleared to allow the water to flow normally. Be sure to shut off the power to the unit before attempting to remove the clog.
