We examined the possible causes for window AC water leakage, and here are the results. Some window AC water leakage is a normal occurrence. But significant moisture escaping the cooling unit is concerning.

Window AC water leaks can be caused by several factors, including (but not limited to):

• Dirty filters
• Low Freon
• Condensation drain clog

Depending on the source of the leak, you will need to take different steps to repair it. Continue reading to learn about these underlying concerns that can cause window air conditioners to leak water. Ultimately, this post will discuss possible solutions for these problems.

Water leaks from window air conditioners?

While condensation is a normal part of many air conditioning systems, including window units, there may be something to be concerned about if there seems to be an excessive amount of water escaping.

How Does A Window AC Water Leak Happen?

Water leaks from window air conditioners can be caused by the following factors:

Dirty Filters

As a result of dirty air filters, moisture is trapped within the system. Ice crystals can form, and when the AC is off, they can melt and cause significant window AC water leaks.

As a rule of thumb, Energy.gov suggests cleaning your air conditioner's filter every two weeks. The frequency may increase according to the location and living conditions of the property.

A household with dusty HomeCareNeed may also experience their window cooling units becoming dirty sooner than later because of pet hair and dander getting into the filter. It might be a good idea for homeowners to clean their window air conditioner filters at least once a week in these cases.

Low Freon

Air conditioners use Freon as a coolant or refrigerant. When Freon levels drop, the AC's ability to convert heat is also reduced. As a result, the unit leaks as it creates more moisture than intended.

A leak in the coolant's reservoir can lead to the substance escaping the appliance and causing additional problems. In most situations, the solution is to recharge the cooling system.

When your window AC unit leaks Freon, you'll notice the following:

• Hissing sounds unknown
• Evaporator or condenser coils that are frozen
• A lack of cold airflow

Your property's energy bill may also surge if you have a refrigerant leak in your window air conditioner. This is because the cooling system uses extra power to run correctly.

Condensation Drain Clog

When the condensation drain is blocked, the generated water vapor inside the window air conditioner will have nowhere to go. Also called the condensate drain, this component serves as an exit route for collected moisture.

1. Excess humidity from the air nearby is removed by the evaporator coil.
2. Condensation of air into water vapor occurs in the coil.
3. Condensate drain pans collect excess moisture before water enters drain lines.
4. The drain pipe transports the water to the outside section of the window AC for discharge.

Besides leaking out, a clogged condensation drain can cause water to pool inside the system. If left untreated, the excess moisture can also cause additional problems, such as permanent breakdowns of the AC.
