Why Is My Air Conditioner Leaking Water Inside The Apartment? Here Are The Top 5 Reasons!

If you’re experiencing a pesky water leak from your air conditioner, you’re not alone. This common problem can cause a variety of issues, from water damage to mold growth. In this comprehensive guide, we’ll explore the most common reasons why your air conditioner might be leaking water inside your apartment and provide step-by-step instructions on how to fix each problem.

Clogged Drain Line

The drain line is responsible for draining condensation from the air conditioner. If the drain line becomes clogged, water can back up and leak into your apartment. To fix this problem, you’ll need to clear the clog.

Tools you’ll need:

• Wet/dry vacuum cleaner
• Shop vac
• Drain snake

Steps:

1. Turn off the air conditioner and unplug it from the power outlet.
2. Locate the drain line. It’s usually a white or clear plastic tube that runs from the air conditioner to the outside of your home.
3. Use the wet/dry vacuum cleaner or shop vac to suck out any water from the drain line.
4. If the drain line is still clogged, you can use a drain snake to clear the obstruction.
5. Once the drain line is clear, pour a cup of bleach down the line to kill any mold or bacteria.

Dirty Evaporator Coil

The evaporator coil is located inside the air conditioner and helps to cool the air. If the evaporator coil is dirty, it can block airflow and cause water to leak from the air conditioner. To fix this problem, you’ll need to clean the evaporator coil.

Tools you’ll need:

• Screwdriver
• Vacuum cleaner
• Coil cleaner

Steps:

1. Turn off the air conditioner and unplug it from the power outlet.
2. Remove the front panel of the air conditioner.
3. Locate the evaporator coil. It’s usually a large, metal coil located behind the front panel.
4. Vacuum the evaporator coil to remove any dirt or debris.
5. Spray the evaporator coil with coil cleaner and let it sit for 10 minutes.
6. Rinse the evaporator coil with water and dry it thoroughly.
7. Reinstall the front panel of the air conditioner.

Broken Condensate Pan

The condensate pan is located under the evaporator coil and collects condensation from the air conditioner. If the condensate pan is broken, water can leak from the air conditioner. To fix this problem, you’ll need to replace the condensate pan.

Tools you’ll need:

• Screwdriver
• New condensate pan

Steps:

1. Turn off the air conditioner and unplug it from the power outlet.
2. Remove the front panel of the air conditioner.
3. Locate the condensate pan. It’s usually a white or clear plastic pan located under the evaporator coil.
4. Remove the old condensate pan and replace it with the new condensate pan.
5. Reinstall the front panel of the air conditioner.

Low Refrigerant Levels

Refrigerant is a chemical that helps to cool the air in your air conditioner. If the refrigerant levels are low, the air conditioner won’t be able to cool the air properly and water can leak from the air conditioner. To fix this problem, you’ll need to add refrigerant to the air conditioner.

Tools you’ll need:

• Refrigerant gauge
• Refrigerant can
• Screwdriver

Steps:

1. Turn off the air conditioner and unplug it from the power outlet.
2. Connect the refrigerant gauge to the air conditioner.
3. Open the refrigerant can and slowly add refrigerant to the air conditioner until the pressure gauge reaches the correct level.
4. Close the refrigerant can and remove the refrigerant gauge.
5. Reinstall the front panel of the air conditioner.

Dirty Air Filter

The air filter helps to remove dust and dirt from the air. If the air filter is dirty, it can block airflow and cause water to leak from the air conditioner. To fix this problem, you’ll need to replace the air filter.

Tools you’ll need:

• New air filter

Steps:

1. Turn off the air conditioner and unplug it from the power outlet.
2. Locate the air filter. It’s usually located behind the front panel of the air conditioner.
3. Remove the old air filter and replace it with the new air filter.
4. Reinstall the front panel of the air conditioner.

Frozen Evaporator Coil

The evaporator coil can freeze if the air conditioner is running for too long without being defrosted. When the evaporator coil freezes, water can leak from the air conditioner. To fix this problem, you’ll need to defrost the evaporator coil.

Tools you’ll need:

• Screwdriver
• Hair dryer

Steps:

1. Turn off the air conditioner and unplug it from the power outlet.
2. Remove the front panel of the air conditioner.
3. Locate the evaporator coil. It’s usually a large, metal coil located behind the front panel.
4. Use the hair dryer to thaw the evaporator coil.
5. Reinstall the front panel of the air conditioner.

In a nutshell: Solving Your Air Conditioner Water Leak Problem
