Heil Central air conditioner leaking at furnace or air handler
When your Heil central air conditioner is leaking water at the furnace or air handler, the evaporator coil and condensate drainage system are the first places to check. The most common cause is an evaporator coil that is not tilted toward the drain outlet, allowing condensation to miss the drain pan and overflow. If the water is leaking from drain pan (also called a drip tray) without overflowing, the pan may be cracked and need replacement. 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 the AC. Turn off power to the unit before inspecting or clearing a drain clog. Replacing a drain pan or other accessible part may be a reasonable DIY repair, but repairs involving 240-volt wiring or sealed-system refrigerant work require a licensed HVAC technician and EPA 608 certification. Enter your Heil central air conditioner model number to find the exact replacement part for your specific system, including a compatible evaporator drain pan, drip tray, condensate drain component, or condensate pump.
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 - Heil 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 - Heil 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.
