How to Fix Air Conditioner Leaking Water Inside

A leaking air conditioner can be a cause for concern, not only because it can affect the efficiency of your air conditioning unit but also because it can lead to water damage in your home.

Understanding the reasons behind these leaks and knowing how to fix them can save you from costly repairs and maintain your indoor air quality. This article will guide you through the common reasons for air conditioner leaks and provide solutions to fix them.

8 Reasons Why Your Air Conditioner is Leaking Water and How to Fix Them

  1. Dirty Air Filter: A dirty filter can block airflow over the evaporator coils, causing them to freeze and melt, leading to excess water that the drain pan may not be able to handle. Fix this by regularly cleaning or replacing your air filter.
  2. Refrigerant Leak: Low refrigerant levels can cause the evaporator coil to freeze and then defrost, leading to water leaks. A professional HVAC technician should fix refrigerant leaks.
  3. Clogged Condensate Drain Line: A clogged drain line is a common cause of water leaks. You can use a wet/dry vacuum to unclog the drain line or call a professional for assistance.
  4. Disconnected Drain Line: If the drain line is disconnected, water can leak from your AC. Ensure the drain line is properly connected to prevent leaks.
  5. Broken Condensate Pump: If the condensate pump is broken, water can’t be pumped out, leading to leaks. You’ll need to replace the pump to fix this issue.
  6. Frozen Evaporator Coil: A frozen coil can lead to water leaks when the coil defrosts. Low refrigerant levels or a dirty air filter often cause this. Fixing the underlying issue will solve this problem.
  7. Damaged Drain Pan: A damaged or rusted drain pan can cause water leaks. You’ll need to replace the pan to stop the leak.
  8. Faulty Float Switch: A faulty float switch can cause the condensate pump to malfunction, leading to water leaks. Replacing the switch should fix the issue.
