3 Reasons Why Your AC Is Leaking Water

AC Leaking Water in Eureka, CA

Warm springtime weather and sweltering-hot summer temperatures will take a toll on your Eureka, CA air conditioner. If you notice that your AC is leaking water, you might wonder if there’s a problem. Here are a few of the reasons why air conditioners leak water and when you should call for an inspection and repair.

1. Clogged Condensate Drain Pipe

The most common reason why air conditioners leak water is a clogged condensate drain pipe. When moisture condenses out of your home’s air, it turns from a gas into a liquid state. The water collects in the drain pan and filters into the pipe. Algae, biofilm, dust and other debris may clog the pipe. When the water has nowhere else to go, it leaks out of the pipe or the drain pan. A leaky condensate pipe will feel wet, and you may notice a puddle on the floor near the pipe.

2. Rusted Drain Pan

After many years of holding water, the drain pan may develop rust or corrosion. Once the drain pan has a crack or hole, the water will leak. You might notice a puddle near the air handler. If the water leaks into the air handler, the unit may power off without warning. This is a safety mechanism to prevent an electrical short-circuit, and it requires an urgent repair.

3. Frozen Evaporator Coil

If the evaporator coil doesn’t have enough airflow, it will get too cold. Moisture that settles on it will freeze during the cooling cycle. At the end of the cooling cycle, the coil warms, and the water melts. A refrigerant leak or dirty air filter are common causes of low airflow, and they require prompt professional repairs.
