Why is My Air Conditioner Leaking Water?


If you’ve noticed water pooling around your air conditioner or dripping from it, you may be wondering what’s causing this common issue. A leaking air conditioner can indicate several potential problems that require air conditioning repair services in order to keep your AC running efficiently.

Let’s explore the common causes of a leaking air conditioner and how AC repairs can help resolve these issues.

Common Causes of a Leaking Air ConditionerClogged Condensate Drain

One of the most frequent reasons for AC leaks is a clogged condensate drain.

Also, prefer quality Water Pipes that are durable and solve the leaking problem of your air conditioner.

Over time, dust, dirt, and debris can accumulate in the drain line, obstructing the flow of water. This blockage causes water to back up and overflow, leading to leaks.

Frozen Evaporator Coils

When the evaporator coils inside your AC freeze due to various reasons like dirty air filters, low refrigerant levels, or airflow issues, they can cause water to accumulate and eventually leak out of the unit.

Rusted Drain Pan

The drain pan beneath the evaporator coils is designed to collect condensate and direct it to the drain line. If the drain pan is rusted or damaged, it may develop cracks or holes, allowing water to leak out instead of being drained properly.

Low Refrigerant Levels

Insufficient refrigerant in your AC system can cause the evaporator coils to freeze up, leading to water leaks when the ice melts. Low refrigerant levels can result from leaks in the system or improper installation.

How AC Repairs Can Help a Leaking Air Conditioner

Dealing with a leaking air conditioner? Here’s how scheduling an air conditioner repair can help:

  • Clearing Clogged Condensate Drain: HVAC technicians can clear clogs in the condensate drain line using specialized tools and techniques. This restores proper drainage and prevents water from backing up and leaking.
  • Fixing Frozen Evaporator Coils: Repairing frozen evaporator coils involves identifying and addressing the root cause, such as replacing dirty air filters, resolving airflow restrictions, or replenishing refrigerant levels as needed. This prevents further ice buildup and subsequent leaks.
  • Replacing Rusted Drain Pan: If the drain pan is rusted or damaged, technicians can replace it with a new one to ensure effective water collection and drainage, preventing leaks caused by pan deterioration.
  • Recharging Refrigerant Levels: If your AC system has low refrigerant levels due to leaks or improper installation, technicians can locate and repair leaks, then recharge the system with the correct amount of refrigerant. This restores optimal cooling performance and prevents coil freezing and water leaks.

If your home is dealing with a leaking air conditioner, the best solution is ultimately to have it repaired. Reach out to your trusted AC repair company to keep your home safe and cool on even the hottest days of the year.
