What is an AC drain line?

The line is an exit route for moisture collected by the evaporator coil as air passes over it. The coil removes humidity from the air and converts it into water. The water drains into the condensate drain pan, enters the drain line, travels down the drain pipe and is deposited outside near the AC's outdoor unit.

Where is the drain pan on my AC unit?

A central air conditioner is normally mounted in a chamber of the furnace above the furnace blower and combustion chamber. The unit's evaporator coils are located here, and directly underneath those coils is the drain pan.

What causes excessive AC condensation?

Dirty air filters– when your AC air filter is dirty, partially blocked, or completely clogged, your air conditioner's evaporator coils are more likely to freeze up, causing excess water to overspill from the drain pan. If the drain pipe is blocked, it could cause water to leak from your AC.

Why is my air conditioner leaking water inside my car?

There are several reasons why a car's AC can leak or drip water into the passenger compartment. One of the most common causes of water dripping inside the car is because of a clogged drain. If the evaporator drain becomes restricted, the water backs up in the HVAC (Heating, Ventilation & Air Conditioning) case.

How much water comes out of an air conditioner?

Air conditioners pull humidity out of the air and funnel the resulting water, or condensate, into a drain. the amount of condensate the unit produces varies, increasing as the outdoor humidity level rises. Most modern air conditioners will produce between 5 and 20 gallons of water per day.

Why is my AC spitting out water?

Any water spitting out from your window air conditioner or central air conditioner comes from one source: condensate dripping from the coils. During the cooling process, the air conditioner takes humidity from the air. This is a result of the Freon coils "sweating" as the indoor air blows across them.

Why does it sound like water in my air conditioner?

If your air conditioning unit is making a noise that sounds like running water, it is likely that the excess condensation is not draining properly and the drip pan is now overflowing. Water sounds can be alarming, but the majority of the time there is no need to worry. It's actually quite normal.

Why is my evaporator coil leaking water?

A common sign of problems with the evaporator coil is a puddle of water under the air conditioning unit.
