Troubleshooting AC Water Leaks: Causes and Solutions

Are you dealing with water dripping from your air conditioner? If you’re here, chances are you’re experiencing a water leak caused by your AC unit. Aside from simply being a nuisance, an AC water leak could lead to further damages if it goes unchecked.

In this article, we’ll look into the various causes and solutions for an AC unit leaking water.

My AC is Leaking Water, What’s Wrong?

When a water leak occurs, the cause can range from a clogged condensate drain line to something much more serious. However, the following are some of the most common causes of an AC unit leaking water:

  1. Dirty air filter – A dirty air filter can restrict airflow and cause condensation to form on the evaporator coil, eventually resulting in water leakage.

  2. Defective condensate pump – The condensate pump helps to move water collected from the evaporator coil out of the drain pan and towards the sewer line. If the condensate pump is broken, it will cause the water-pan to overflow and cause a water leak.

  3. Condensate drain line clogged – A clogged condensate drain line can cause the water-pan to overflow and result in water leakage.

  4. Refrigerant leak – Leaks in the refrigerant can cause excess humidity and condensation to form on the evaporator coil, resulting in water leakage.

Solutions for an AC Unit Leaking Water

Now that we understand the various causes of an AC water leak let’s take a look at some of the solutions.

  1. Clean air filter – The first step in tackling a water leak from an AC unit is to check and replace the air filter. If the filter is dirty or not properly fitted, the restricted airflow will cause condensation and water leakage.

  2. Replace the condensate pump – A damaged condensate pump is often the cause of water leakage. Replacing a damaged or non-functioning condensate pump can fix the leak.

  3. Clean the condensate drain line – If a clogged condensate drain line is the culprit, unclogging the line may fix the leak. For best results, enlist a professional to clean the line.

  4. Refrigerant leak repair – A trained technician can identify and repair any leaks in the refrigerant lines. If a refrigerant leak is causing the water leak, the technician can repair and recharge the system.


If you’re dealing with an AC unit leaking water, the cause can range from a clogged drain line to a refrigerant leak. Ensuring the air filter is clean, the condensate pump is functioning and the drain line is unclogged are some of the solutions. If you’re unable to fix the problem yourself, calling a qualified technician is recommended.

When tackling a water leak from your AC unit, you should understand the cause and the solutions. With the right understanding, measures and actions, you can be well-equipped to tackle any water leak issues without needing to call for help.

My AC is Leaking Water, What’s Wrong?

If your air conditioner is leaking water, it could indicate anything from a normal happening to a sign of a faulty part or system malfunction. Any potential water leak in a cooling system should be inspected by a professional HVAC technician, especially if it is a problem that occurs repeatedly. To avoid the problem in the future, the HVAC technician may recommend maintenance or other preventive action. Below, we will detail some manufacturer recommendations, local appliance companies’ or HVAC technician’s recommendations as preventive action to avoid issues in the future.

Have Regular Maintenance

One of the best preventive actions to ward off issues, including water leaking from your air conditioner, is to have regular maintenance. This involves having a qualified technician checking your system annually, typically in the spring time before the season begins, to ensure your system is working at its peak efficiency. During this inspection, your HVAC technician can detect any potential problems and fix them before major issues occur.

Check Your Filtration System

If your filtration system is clogged or otherwise unable to do its job correctly, it can cause your air conditioner to leak water. Have a qualified technician replace and upgrade any necessary filtration components.

Clean the Condensate Drain and Evaporator Coil

To provide the cooling efficiency and proper temperature balance, your air conditioner utilizes the condensation it collects to move heat and moisture out of your home. Make sure your condensate drain lines are cleared of debris and clogs and free-flowing. Furthermore, the evaporator coil should also be checked for dirt and dust and cleaned as necessary. Additionally, the refrigerant level should be checked for proper charge and recharged if necessary.

Remove Debris from Outdoor Units

If your air conditioner is leaking from the outdoor unit, it is likely debris has blocked the condensate drain lines. To avoid this, it is important to clear the area around the outdoor unit. This includes leaves, grass, sticks and other debris. Not only will clearing the area help prevent clogs forming, but it will also help protect your system from exposure to dirt and other materials, which could affect its performance.

Replace the Crankcase Heater

The crankcase heater on an air conditioner helps to keep the evaporator coil functioning properly. If the crankcase heater fails, it can cause your air conditioner to leak water. Have a qualified technician inspect the crankcase heater, and replace it if necessary.

Test and Adjust the Expansion Device

If your air conditioner has an expansion device, have a qualified technician test and adjust it to ensure it is functioning properly and does not restrict or obstruct the flow of refrigerant in your system.

By following the above preventive action, you can help reduce the risk of future problems with your air conditioner, including water leakage. If you have any questions or concerns, it is always best to contact a qualified HVAC technician to inspect and make repairs as needed. This will ensure your system is functioning properly and efficiently for the coming cooling season.
