Where does the condensate come from that forms on the evaporator?
When the water vapor in your warm household air hits the cold evaporator coils, the water vapor condenses into liquid form and drips down into the condensate pan, which drains the water away outdoors. This is how your evaporator coil reduces the humidity in your home.
What causes excessive condensation on evaporator coil?
Dirty Air Filter Leading to Frozen Evaporator Coil Dirty home air filters don’t facilitate adequate airflow over the evaporator coil. Without proper airflow, the coil gets too cold and freezes. When this ice melts, dripping into the condensation pan, it can overflow.
How does a condensate evaporator pan work?
It’s similar to a glass of ice water on a hot day. After a few moments in a warm environment, the glass is covered in beads of water. In the same way, tiny water droplets collect along your evaporator coil. Water slips down the sides of the evaporator coil and right into the condensate pan fitted below.
How do I know if my evaporator core is leaking?
If the airflow feels weak or doesn’t turn on right away, you might have a refrigerant leak. Other signs include warm air coming through the vents, hissing noises from the outdoor A/C unit, frozen evaporator coils on the outdoor unit, and unpleasant odors when you turn on the heating or cooling system.
Why is my stand up air conditioner leaking water?
A clogged condensate drain line is the most common cause of water leaking from your AC into your home. If the drain line gets clogged with dust, dirt, sludge or mold, that water backs up into your home. There are multiple unclogging methods, like using a wet/dry vac on the condensate line.
Can a code drain switch cause an evaporator to freeze?
BTW, for new installations, by code drain switches and float switches are required. If the air filter is extremely clogged, a duct is collapsed, the evaporator coils are plugged with dirt or dust because no air filter was kept in the system, or there is a low charge of Freon ®, the evaporator coil will freeze.
What causes condensation in an air conditioner drain pan?
Normally if the air handler unit is old enough to have a rusted evaporator condensation pan that leaks, it is time to change the air handling unit. Unit or Drain Pan Slope. If the evaporator drain pan is not sloped toward the drain, the water will not drain from the evaporator pan properly.
When to change the evaporator in an air conditioner?
In certain cases, the entire air handling unit must be changed out. In other cases, the evaporator coils and evaporator condensation pan must be changed. Normally if the air handler unit is old enough to have a rusted evaporator condensation pan that leaks, it is time to change the air handling unit.
How do you unclog an evaporator drain?
That allows the water to drain. This should be done by an HVAC Contractor. Sometimes the drain line needs to be cut and then redone after the line has been blown. Other methods to unclog the evaporator drain are to use high-pressure nitrogen, a water hose, or a shop vacuum to suck the line out.

Where is the evaporator coil on a split system air conditioner?
With a typical split-system central air conditioner, the evaporator coil is often located inside the home or garage, as a part of the air handler unit. If the indoor unit is a furnace, the evaporator coil is typically mounted where the outgoing air flows. If it’s a fan coil, the evaporator coil is typically located inside the fan coil cabinet.
