It’s hard to imagine life without air conditioners.

In San Marcos, temperatures can rise quickly, which means your AC system is pushed to work hard throughout the year.

Even though you feel the cool air inside, part of your system lives outdoors. This outdoor portion is called the condenser unit, and its job is to release warm air from inside your home into the outside environment.

While mowing your lawn, you might notice something concerning: a puddle of water collecting at the base of your condenser. Big enough for a kid to splash in, but definitely not a good sign.

Here are a few common reasons your outdoor condenser might be leaking water.

The pipes are clogged

A blockage in the pipes can lead to leaking. Because an AC system operates in a damp environment, algae or mold may begin growing inside. Just like a clogged household drain, a backup in the AC line can cause water to overflow.

The air filter is dirty

Air filters don’t last forever. Over time, they fill with dust, hair, and debris. If they aren’t replaced regularly, airflow becomes restricted and the evaporator coils freeze. When the ice melts, excess water can overflow from the drain pan and create a puddle around the condenser.

The condensate pan is broken

This pan catches water that drips from the evaporator coils. After years of use, the pan may rust or crack, allowing water to escape. The harder your unit works, the more water builds up and leaks through a damaged pan.

It’s cold outside

Although San Marcos is warm most of the year, winter can still bring chilly, windy weather. Cold temperatures can cause the cooling coils to freeze, leading to leaks when the ice melts. Always remember to turn off your AC when temperatures drop.

The refrigerant needs a top up

Refrigerant is essential for your AC to absorb heat and create cool air. If levels are too low, the system builds up pressure, causing the evaporator coils to freeze. When they thaw, the extra water often ends up outside near the condenser.

There’s air leakage

Think of a cold drink sitting outside on a hot day. Condensation forms on the glass as warm air hits the cold surface. The same thing happens when hot outdoor air leaks into your condenser. Condensation builds up and drips out of the unit.

A technician will need to inspect the unit’s seals and check for cracks or gaps.

The unit wasn’t installed correctly

AC installation is complex and must be done by a licensed, certified technician. If the system wasn’t installed properly, the condenser may not be level, the drainage line may be misaligned, or the pipes may be the wrong size. Any of these issues can cause consistent leaking.
