What is That Gross White Slime in My AC Drain Line?

Keeping the appliances in your home running smoothly is one of the most important jobs for any homeowner. When you notice something wrong with your home, your immediate reaction is to try and fix it. And while some issues may require professional repairs and maintenance, others can be resolved relatively easily. A puddle of water around your air conditioning unit is no exception.

If you notice that your AC is leaking, the odds are good that the drain line is clogged. This is a common problem and something that will happen with almost every air conditioner at some point or another especially if your unit has been working overtime to keep your home at a comfortable temperature.

While clearing the drain line is relatively easy, it’s important to know how to avoid making the problem worse. To that end, we have laid out what not to do when your AC drain line is clogged.

What Happens When Your AC Drain Line Is Clogged?

A clogged AC drain line can cause several problems. The air conditioner removes humidity from the air as it cools your home. This moisture collects in the drain pan and is then drained away through a small pipe known as the drain line. If the drain line gets blocked, you may experience reduced cooling efficiency, water leakage, frozen coils, Mold and mildew growth, and even a shutdown of your entire air conditioning system.

What Causes AC Drain Line Clogs?

Clogged AC drain lines occur due to dirt, debris, and microbial growth like algae and Mold. Inadequate maintenance and low refrigerant levels contribute to excess moisture, which can lead to a blockage. Improper installation, incorrect slope of the drain line, or a flawed design can also hinder proper drainage. Regular maintenance of your AC drain line will help prevent these issues.
