Luxaire Central air conditioner leaking at furnace or air handler
If your Luxaire air conditioner is leaking water at the furnace or air handler, the evaporator coil is usually not positioned correctly, allowing condensation to miss the drain outlet and overflow. An incorrectly tilted evaporator coil is the most likely cause of an air conditioner leaking water, followed by a cracked drain pan (also called a drip tray). If water is leaking from the pan without overflowing, inspect it for cracks and replace the damaged part. A clogged condensate drain tube 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 air handler before clearing a clog, and keep water away from electrical components. These drain and pan repairs are generally within a careful DIYer's scope, but stop if you must work near exposed 240V wiring or sealed-system components. Enter your Luxaire model number to find the exact replacement drip tray, drain pan, hose, tube, or fitting for your central air conditioner.
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 - Luxaire 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 - Luxaire 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.
