What to Do If Your Mini Split Is Leaking Water?

A mini split air conditioner is a reliable and efficient cooling solution, but if you start noticing water leakage, it’s important to address the issue quickly. Water leaks can lead to mold growth, damage to your walls, and reduced efficiency of your system. Here’s what might be causing the leak and how to fix it.

1. Clogged Air Filter

When the air filter is dirty, it restricts airflow, causing the evaporator coil to freeze. As the ice melts, it can drip water from your unit. Solution: Clean or replace your air filter every 2-4 weeks to ensure proper airflow.

2. Blocked Drain Line

Your mini split removes moisture from the air, and this condensation is drained through a small pipe. If this drain line is clogged with dirt or debris, water can back up and start leaking from the indoor unit. Solution: Flush the drain line with warm water or a mild cleaning solution to clear any obstructions.

3. Incorrect Installation or Leveling

If your indoor unit isn’t installed at the correct angle, water might not drain properly and could accumulate inside the unit. Solution: Ensure that the mini split is slightly tilted downward toward the drain line.

4. Low Refrigerant Levels

A refrigerant leak can cause your evaporator coil to freeze, leading to excessive condensation once it thaws. Solution: A refrigerant check and refill should be done by a professional HVAC technician.

5. Drain Pan Issues

The drain pan collects condensation, but if it’s cracked or misaligned, water can escape instead of draining properly. Solution: Inspect the drain pan for damage and replace it if necessary.
