Air Conditioner Dripping Water? Here’s Why and How to Fix It

AC dripping water

Have you ever come home to a puddle of water beneath your air conditioner? It’s a frustrating and often unsightly problem that can leave you feeling confused and overwhelmed. When your air conditioner starts dripping water, it’s usually a sign of a problem with condensation, drainage, or airflow. But fear not! it’s often a relatively simple problem to solve. 

In this comprehensive guide, we’ll delve into the most common causes of AC water leaks and provide step-by-step solutions. Whether you’re a DIY enthusiast or prefer to leave the technical work to the professionals, we’ve got you covered. So, let’s dive in and discover why your AC is dripping and what you can do about it. 

Air Conditioner Dripping Water

1. Clogged Condensate Drain Line

Why it happens

The AC removes moisture from the air and condenses it into water. This water is supposed to drain out through a condensate line. If the line is clogged (often with dirt, algae, or debris), water backs up and leaks. 

How to fix it

  • Turn off the AC. 
  • Locate the drain line, which is typically a small PVC pipe. 
  • Use a wet/dry vacuum to clear the line or flush it with a mixture of water and bleach. For stubborn clogs, you may need to use a drain snake.

2. Dirty Air Filter

Why it happens  

A dirty filter restricts airflow over the evaporator coil, causing the coil to get too cold and freeze. When the ice melts, excess water can overflow the drainage system. 

How to fix it 

  • Turn off the AC. 
  • Locate the air filter, which is usually behind the front grille. 
  • Remove the filter and inspect it for dirt and debris. 
  • Replace the filter with a new one. Filters should generally be replaced every 1-3 months depending on usage and air quality.

3. Low Refrigerant 

Why it happens 

Low refrigerant levels can cause the evaporator coil to freeze, and when it melts, water can leak. 

How to fix it 

You’ll need a professional HVAC technician to address this issue. They will use specialised equipment to check the refrigerant levels and recharge it if necessary. They will also identify and repair any leaks causing the refrigerant loss. 

4. Improper Installation 

Why it happens  

If the air conditioner is not installed correctly, the drainage system might not function as it should, leading to water leaks. 

How to fix it 

  • Check if the AC is level. If it’s tilted or uneven, water may pool and drip inside. 
  • If it’s a new installation and the issue persists, contact the installer. They can assess the setup and make any necessary corrections.

5. Damaged or Rusted Drain Pan 

Why it happens  

The drain pan collects water before it drains out. If it’s damaged or rusted, water can leak out. 

How to fix it 

  • Inspect the drain pan, which is located underneath the evaporator coil. 
  • If it’s damaged, replace it. A technician can help if you’re unsure. 

6. Excessive Humidity 

Why it happens

During humid weather, the AC may have to remove more moisture than usual, causing the drainage system to be overwhelmed. 

How to fix it 

  • Use a dehumidifier alongside your AC to reduce moisture in the air. 
  • Ensure proper airflow and ventilation in the room. Open windows or doors periodically to allow fresh air to circulate. 
Preventing Future AC Leaks

Preventing Future AC Leaks

  • Regular maintenance can help prevent many of these issues. Have your AC serviced annually by a professional. 
  • Pay attention to any unusual noises or smells coming from your AC. These can be signs of a problem. 

If you’re unsure about any of these steps or if the problem persists, it’s best to call a professional HVAC technician. They have the expertise to diagnose and repair the issue efficiently.
