There are many reasons an HVAC system might start to leak, and some require more serious intervention than others. A small amount of condensation is normal for residents of hot and humid climates like Georgia’s, but if the leaking is excessive or continues when your system is off, that’s a sign of a larger issue. Here’s a closer look at the most common causes of water forming in air conditioners.

Why Your AC May Be Leaking

1. Poor Installation

If your AC unit was recently put in, it shouldn’t be giving you much trouble. Leaks from brand-new air conditioners are often the result of improper installation. The technician may have situated it incorrectly or chosen the wrong size for your home entirely. 

2. Clogged Drain Pipe

Central air conditioning systems remove condensation that forms within your indoor unit through drain pipes. If dirt, mold, or sludge accumulate enough to form an obstruction within those pipes, water can leak into your home. The only solution is to unclog the affected drain pipe. You likely won’t have the right equipment to vacuum out the blockage, so call a qualified HVAC contractor.

3. Dirty Air Filter

AC units need air flowing through them to function. When too much dirt, dust, hair, and other debris collect on your air filter, it blocks the airflow and causes the unit’s evaporator coil to freeze. As it melts, the once-frozen condensation will drip to the point of overflowing from the drain pan. Cleaning or replacing your air filter regularly will prevent this type of leak.

4. Damaged Drain Pan

A unit’s drain pan serves to collect water droplets as they fall from the evaporator coil. If the drain pan is faulty or damaged, the condensation will simply leak from your air conditioner. This is more common in older models. Old, rusted drain pans will need to be replaced.

5. Low Refrigerant Levels

When your refrigerant levels begin to run low due to supply or a coolant leak, the pressure inside your AC unit will lower as well. Like a lack of airflow, low pressure will cause the evaporator coil to freeze. This may result in the same type of runoff over the drain pan.

If you’re dealing with a refrigerant leak, you might be able to hear hissing or bubbling from your unit. Have your HVAC contractor inspect the issue right away. If a bad leak goes unchecked long enough, you may need to replace the entire unit.
