Identify the Cause of the Leak

The first step in resolving a water leak is identifying its cause. Common reasons for leaks include:

Clogged Drain Pipe: Dust, dirt, and algae can accumulate in the drain pipe, causing a blockage.

Dirty Air Filters: When filters are dirty, airflow is restricted, leading to the evaporator coil freezing and then melting, causing excess water.

Improper Installation: Incorrect installation can lead to water leakage, especially if the unit is not level.

Low Refrigerant Levels: Low refrigerant can cause the evaporator coil to freeze, and when it melts, the excess water may leak.

Damaged or Rusted Drain Pan: Over time, the drain pan can become damaged or rusted, leading to leaks.

Check and Clean the Air Filters

Dirty air filters are a common cause of water leaks. Remove the filters and inspect them for dirt and debris. Clean them with warm, soapy water and let them dry completely before reinstalling. Regular cleaning of filters can prevent future leaks and improve the air conditioner’s efficiency.

Inspect the Drain Pipe

The drain pipe is responsible for carrying excess water out of the unit. A clogged drain pipe is one of the most frequent causes of leaks. To clean the drain pipe:

Locate the drain pipe and gently detach it.

Use a vacuum to clear any blockages.

For thorough cleaning, you can use a mixture of water and vinegar to flush out the pipe.

Reattach the drain pipe securely.

Check the Drain Pan

Examine the drain pan for any signs of damage or rust. If the pan is damaged, it may need to be replaced. In some cases, a temporary fix can be made using a waterproof sealant.

Ensure Proper Installation

An improperly installed unit can lead to water leaks. Ensure that the air conditioner is level. If it is not, adjust the positioning. Sometimes, adding support brackets can help level the unit.

Monitor Refrigerant Levels

Low refrigerant levels can cause the evaporator coil to freeze. If you suspect this is the issue, it’s best to contact a professional technician. Handling refrigerants requires specific skills and tools, and improper handling can be dangerous.

Regular Maintenance

Regular maintenance can prevent most issues that cause water leaks. At Aircool Aircon, we recommend scheduling a professional maintenance service at least once a year. This includes thorough cleaning, refrigerant level checks, and ensuring all components are in good working condition.
