Furnace leaking water when the air conditioning (AC) is on is a common household problem. It’s crucial to address this issue promptly to prevent further damage. In this post, we’ll explore the causes, solutions, and detailed FAQs related to this problem.

Understanding the Issue

When your AC is running, it’s normal for condensation to occur. However, when this water starts leaking from your furnace, it indicates an issue. The primary reasons include:

  1. Clogged Condensate Drain Line: The most common cause.
  2. Faulty Condensate Pump: If the pump is broken, water can’t be expelled properly.
  3. Dirty Air Filters: Lead to blocked airflow, causing freezing over and then melting.
  4. Low Refrigerant Levels: Can cause coils to freeze and leak water when melting.
  5. Improper Installation: Incorrect sizing or installation can lead to leaks.

Table: Common Causes and Solutions

Cause Symptoms Solutions
Clogged Condensate Drain Water pooling, musty smell Clean the drain line, use AC drain line cleaner
Faulty Condensate Pump Water leakage, pump noise Replace or repair the pump
