Why Is My Home Air Conditioner Leaking Water Inside?

Air conditioning is essential, especially during the sweltering summer months. However, it can be distressing to find water leaking inside your home from your air conditioner. Understanding the causes of this issue and knowing how to address them can prevent further damage and ensure your AC runs efficiently.

How and Why Water Forms in Your Air Conditioner

• The Cooling Process
  Modern air conditioning systems generally consist of two main components: an indoor unit and an outdoor unit. The indoor unit contains an evaporator coil, which cools warm air as it passes over the coil. This process is similar to how water droplets form on the outside of a cold glass of water on a hot day. As warm air contacts the cold evaporator coil, condensation forms.
• Condensate Drainage
  The condensation that forms on the evaporator coil drips into a condensate pan. From there, the water is routed outside your home or into an interior drain via a PVC drain line. This system works efficiently under normal conditions, but various issues can cause water to leak inside your home.

Common Causes of a Leaking Air Conditioner

1. Clogged Condensate Drain Line

One of the most common causes of water leaking from your AC unit is a clogged condensate drain line. Over time, the drain line can become clogged with dirt, dust, algae, and other debris. When this happens, water backs up and overflows from the drain pan, causing leaks inside your home.

Solution:

• DIY Fix: Use a wet/dry vacuum to remove the clog from the condensate line.
• Professional Help: If DIY methods don’t work, contact a professional HVAC technician who can use specialized tools to clear the blockage.

2. Damaged or Rusted Drain Pan

If your air conditioning system is older (typically 12-15 years), the drain pan may be damaged or rusted through. This damage allows water to fall right through the pan and leak into your home.

Solution:

• Replace the damaged or rusted drain pan with a new one.

3. Broken Condensate Pump

In homes where the air conditioning unit is installed in the basement, a condensate pump is used to pump water outside. If this pump breaks, water is no longer pumped outside and will leak into your home instead.

Solution:

• Repair or replace the broken condensate pump.

4. Dirty Air Filter

A dirty air filter can block airflow over the evaporator coil, causing the coil to freeze. When the ice on the coil melts, the resulting water can overflow the drain pan.

Solution:

• Check and replace the air filter regularly, ideally every 1-3 months, depending on usage and season.

5. Low Refrigerant Levels

Low refrigerant levels cause the evaporator coil to become excessively cold, leading to freezing. When the frozen coil thaws, it can cause an overflow in the drain pan.

Signs of Low Refrigerant:

• The air conditioner isn’t cooling effectively.
• You hear a hissing or bubbling noise, indicating a refrigerant leak.

Solution:

• Have a qualified HVAC technician inspect the system and refill the refrigerant. They will also repair any leaks.

6. Frozen Evaporator Coils

Frozen evaporator coils are typically caused by restricted airflow, low refrigerant levels, or dirty coils. When the ice melts, it can quickly fill the drain pan and cause leaks.

Solution:

• Regularly maintain your AC unit to keep coils clean and ensure adequate airflow. Monitor refrigerant levels and have any issues addressed promptly.

7. Improper AC Installation

An improperly installed air conditioning unit or a poorly configured condensate drain line can lead to drainage problems and water leaks.
