What To Do When Water Leaks From Your Air Conditioner

Home » Blog » What To Do When Water Leaks From Your Air Conditioner

It can be alarming when you discover water around your AC unit. While some moisture is normal in an air conditioning system, visible water leaks are not. These leaks can lead to water damage, mold growth, and reduced cooling performance if ignored.

Luckily, Apex Pros Plumbing, Electrical, Heating, and Air offers fast, reliable air conditioning repair to quickly identify and fix the root cause of any AC leak. Read on to learn why cooling systems produce water, the common causes of leaks, and how to prevent them in the future.

Why Do Air Conditioners Produce Water?

As your air conditioner draws in warm air, it passes over the cold evaporator coil. The moisture in the air then condenses and drips into a drain pan. The water can then flow outside through the condensate drain line. However, when this drainage is interrupted, it can cause a leak.

Common Causes of an AC Water Leak

Unfortunately, water leaks from AC systems aren’t unusual. There are a few common causes of leaks that can lead to cooling issues:

Clogged AC Drain Line

Your AC drain line is responsible for safely draining condensation from your home. Over time, dirt, algae, and debris can block the drain line. When this occurs, water will back up into the drain pan and overflow. This is perhaps the most common cause of AC leaks and requires unclogging the drain.

Dirty Air Filters

Another common cause of leaks that doesn’t require AC repair is dirty air filters. Blocked filters can restrict airflow, causing the evaporator coil to freeze. When the ice then melts, excess water can overflow the drain pan. This is why replacing the filter every 1-3 months is critical, along with routine AC maintenance.

Damaged Drain Pan

The drain pan beneath the evaporator coil collects condensation before directing it to the drain line. As the system ages, the pan can deteriorate. Older systems are especially vulnerable to cracks, rust, or wear that can allow water to escape.

Refrigerant Problems

Low refrigerant levels or leaks can contribute to frozen coils and water leaks. Without proper refrigerant levels, the evaporator coil can become too cold. As the ice melts, it creates a leak. This issue specifically requires professional diagnosis and repair, as refrigerant requires specialized equipment and EPA-certified handling.

What to Do If Your AC Is Leaking Water

If you notice water pooling at the base of your AC system, follow these simple steps to troubleshoot the issue before calling a professional for repair.

1. Turn Off the System

At the first sign of leaks, turn the system off at the thermostat. This will help to prevent further water damage and reduce the risk of additional HVAC problems. If water is near any electrical components, avoid touching the equipment until it has been inspected.

2. Check for Simple Issues

Homeowners can attempt to troubleshoot the problem by looking for simple issues that don’t require professional repair. This includes inspecting the air filter to determine if you need a replacement. You can also look for obvious signs of a clogged drain line and remove any standing water if safe to do so.

3. Schedule Professional Air Conditioning Repair

If you are unable to find the source of your leak, it’s time to call a professional. Technicians can inspect the drain system, coils, refrigerant levels, and other components to ensure they are working properly and diagnose the problem. Plus, professional service helps prevent recurring leaks and costly damage.

How to Prevent Future AC Water Leaks

There are several ways that homeowners can protect against future leaks and the potential damage they can cause to their homes:

  • Change air filters regularly: Clean filters free of blockages help your AC system efficiently remove moisture from the air and ensure it drains properly.
  • Schedule annual AC maintenance: Annual AC tune-ups allow technicians to identify and fix minor issues that, if left unaddressed, could lead to future leaks.
  • Keep the condensate drain system clean: Homeowners can clear out drain line tubes and monitor the drain pan for any physical damage that may impact performance.
  • Address minor issues: Don’t wait for a simple issue to become a major repair before taking action. Prompt repairs for even the smallest issues can help you prevent leaks and the hazards that they cause.
