Air conditioners aren’t supposed to leak water. While it’s true that they do pull moisture from the air via condensation, the condensation should never find its way into a system’s inner workings if it is operating as intended.

Of course, this doesn’t mean that an AC system won’t suffer from a water leak. And, from time to time, many do. In fact, water around the base of an HVAC unit is one of the most common reasons why homeowners call for air conditioning repair Wilmington NC. Still, this is not something that should be taken lightly as water leaking from an AC unit can be a very serious and potentially dangerous problem.

Here, we’ll look at some of the most common reasons why an AC unit might leak.

Clogged Condensate Drain Line

As the AC unit pulls moisture from the air, it collects in the condensate pan where it flows down a drain and is expelled into your home’s plumbing or it is directed outside. Occasionally, the drain line can become clogged by dirt, mold, and even insects. Since the water has no way to leave the condensate pan, it will eventually overflow and start dripping down into the system itself.

One of the most common causes of a clogged condensate drain is actually a dirty evaporator coil. When the evaporator coil is dirty, the dirt mixes with the water and it eventually winds up in the condensate pan where it can build up and collect at the top of the drain, thus sealing it over and preventing water from escaping.

Rusted Condensate Pan

Because the condensate pan’s job is to collect water, over time, it can start to rust. This results in the pan’s base becoming pockmarked with holes that will allow water to leak into the system before it has a chance to make it to the drain. Some, but not all, air conditioners have secondary drain pans that feature a float switch safety measure that will actually turn the system off in order to prevent the water from continuing to collect.

Poor Installation

If your AC system is relatively new, then the cause of the leak shouldn’t be a clogged drain or rusted pan. In most cases, the problem is related to an incorrect installation or a poorly designed condensate trap.
