Goodman Central air conditioner leaking at furnace or air handler
If your Goodman central air conditioner is leaking water at the furnace or air handler, start with the evaporator coil. The coil should tilt slightly toward the drain outlet so condensation flows into the pan; if it is level or tilted incorrectly, water can overflow and cause an air conditioner condensate leak or water under the furnace from AC operation. Next, inspect the evaporator drip tray. A cracked drip tray can leak even when it is not overflowing and usually requires replacement. A cracked evaporator drain pan can cause the same air handler leaking water symptom. If water is overflowing the pan, check the condensate drain line, drain tube, and drain trap for a clog that is backing water up. Turn off power at the disconnect box or circuit breaker before clearing a clog, and do not work on exposed 240-volt wiring. These checks do not normally involve refrigerant, but coil repositioning or any repair inside the sealed system requires an EPA 608-certified HVAC technician. Enter your Goodman central air conditioner model number to find the exact replacement drain pan or other part for your specific unit.
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 - Goodman 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 - Goodman 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.
