Dealing with Recurring Drain Line Issues in Your Air Conditioner: Understanding and Preventing White Slime Buildup

If your air conditioner frequently has drain line problems, white slime might be the culprit. This substance has become a prevalent issue in HVAC systems, particularly in southern US states during peak summer months. White slime, a gelatinous biofilm, clogs drain lines, causing AC malfunctions.

What is White Slime and Its Origin?

Before you panic, rest assured that white slime isn’t uncommon. It’s a biofilm composed mainly of bacteria called Zooglea. Zooglea forms a protective layer around itself, thriving in the dark, damp environment of your AC's drain pan. The process of dehumidification in your AC, combined with dust and dirt on the evaporator coil, creates an ideal breeding ground for these bacteria.

Potential Problems Caused by White Slime

While initially harmless, white slime can quickly cause blockages in your air conditioner’s drain line. A blocked drain line prevents moisture from exiting your home, leading to overflow and potential water damage. Even with regular maintenance, Zooglea can clog your lines rapidly. Some AC systems may shut down to prevent overflow, but others might not, leading to unnoticed water damage and mold growth.

Signs of white slime issues include:

• your AC has stopped cooling 
• error messages on your thermostat 
• standing water near your AC unit 
• a musty smell from your vents
