If your air conditioner is leaking a small amount of water, this is generally part of its normal operation and occurs when the system collects a small amount of moisture from condensed air. This leakage should be automatically collected and removed from the system via the drain line.

It’s when this leak become more than a drip and gets to the point it is causing stains or pooling that it can be a problem. Read on to see some of the most common reasons your air conditioner could be leaking water.

1. The air filter is clogged or dirty

A clogged or dirty air filter can restrict the airflow over the evaporator coils in your air conditioner. This can cause the temperature to drop and the coils to ice over.

When the coils thaw, water can drip out of your air conditioner.

Regular cleaning and maintenance can help you ensure your air conditioner’s filter allows for a clear airflow.

2. Blocked drain hole

Another contributing factor to your air conditioner leaking water could be a blocked drain hole. Like the air filter, the drain hole needs to be regularly checked for dirt and debris. This can lead to the water collection pan filling with water and ultimately overflowing.

A regular maintenance schedule to ensure the system is clean will help prevent any blockages occurring from dirt and debris.

3. Drain line disconnected

If there has been activity around the drain line it may have become disconnected and lead to water leaking from your air conditioner.

We can provide a regular maintenance schedule to ensure all issues are addressed before they lead to bigger problems.

4. Broken condenser pump

The condenser pump pushes any condensed water into the drain pan so the water can exit the air conditioning unit through the drain hole and drain line. If this is broken, water can build up until it starts to leak. We can either replace or repair the condenser pump, depending on the level of to prevent any future leakages.

5. Low refrigerant levels

If your air conditioner is low on refrigerant, the evaporator coils can freeze over when it is in use.

When the air conditioner is turn off, the ice melts and causes your air conditioner to leak. If you notice ice forming, you should stop use of your air conditioner immediately and get in contact with our team so we can repair or replace the system before more damage is done.
