AC Leaking Water in NJ? Causes, Quick Checks, and When to Call a Pro

If your AC is leaking water, you are not alone. In Morris County and North NJ, we see this every summer, especially in older homes with attic or basement air handlers. The good news is most leaks are fixable quickly, but ignoring them can cause water damage or a full system shutdown.

Common causes of AC leaks

• Clogged condensate drain line from algae or debris
• Frozen evaporator coil that melts after the system cycles off
• Cracked or rusted drain pan under the indoor unit
• Loose drain line connection after vibration or service
• Improper slope on the drain line so water backs up

What you can check safely

• Turn the system off and look for standing water in the drain pan
• Check the drain line outlet near a floor drain or outside wall
• Replace a dirty air filter to restore airflow
• If you see ice on the copper lines, let it thaw with the fan only

Do not open sealed panels or handle electrical components. If water is dripping near wiring, call a pro immediately.

When to call Air2Cool

• Water is pooling around the furnace or air handler
