What Causes AC Leaks? Expert Diagnosis in Lakewood Ranch

Finding water pooling around your air conditioner is alarming. While it might seem minor, an AC leaking water is a problem that needs prompt attention to prevent water damage, mold growth, and potential system failure. Understanding the common causes can help you know when to call for professional help in Lakewood Ranch.

Here are the most frequent reasons for AC leaks, diagnosed by the experts at Reliable Air Conditioning and Heating:

  1. Clogged Condensate Drain Line: This is the most common culprit. As your AC cools and dehumidifies, it produces condensation, which normally flows outside through a drain line. If this line becomes clogged with algae, dirt, or debris, water backs up and overflows the drain pan, leaking into your home.
  2. Rusted or Damaged Drain Pan: The drain pan sits beneath the indoor unit's evaporator coil to catch condensation. Over time, especially with older units, the pan can rust through or crack, allowing water to leak out.
  3. Broken Condensate Pump: If your indoor unit is located below the drain line exit point (e.g., in a basement or closet), a condensate pump is used to push the water out. If this pump malfunctions or fails, water will overflow.
  4. Dirty Air Filter: A severely clogged air filter restricts airflow over the evaporator coil. This can cause the coil to get too cold and freeze over. When the ice melts, it can overwhelm the drain pan and cause leaks.
  5. Low Refrigerant: Incorrect refrigerant levels can also cause the evaporator coil to freeze. Similar to a dirty filter scenario, melting ice leads to excess water and potential leaking. This also indicates another underlying issue – a refrigerant leak – which needs professional repair.
