Top Reasons Why Your AC Unit is Leaking

Is your home’s AC unit leaking or pooling up water? Even if your unit continues to blow cool air, it’s important to find out what’s causing it to leak and fix it. Allowing your AC to leak water may contribute to your unit short-circuiting, which is something no homeowner wants to happen.

Identify The Leak

First and foremost, you need to identify where the water is leaking or pooling up at. Closely inspect the exterior of your unit to see how severe the situation is. Don’t physically open up your AC unit, as doing so is both dangerous and illegal.

Condensation Drain Line

One of the jobs an AC unit performs is the removal of moisture in the air. Once air from inside of your home is sucked into the return vent, the evaporator coils catch that moisture and release them down into the condensation drain line. In most homes, the condensation drain line is a simple set of PVC pipes which go from the evaporator coils to the exterior siding of the home.

If the condensation drain line in your home becomes clogged with debris or algae, it could potentially prevent the water from draining properly. Inspect the drain line outside of your home and look for any signs of algae colonies growing. Many homeowners fail to properly clean and maintain their condensation drain lines, which is why they become clogged so frequently.

Unfortunately, there’s no easy to way to thoroughly clean your condensation drain line. You can inspect the exterior of the pipe, but you need a special pressurized watering tool to really give it a thorough cleaning.

Internal Drain

If the internal drain in your home’s AC unit becomes blocked, it could lead to water pooling up around the unit. When large amounts of dust, dirt and debris get sucked into the internal drain, it will prevent water from passing through. This is a scenario that you’ll need to call a professional HVAC technician to come out and inspect your unit.

To help prevent the likelihood of a clogged internal drain, keep your air filters maintained and replaced once a month. Not only will using new air filters prevent this from happening, but it will also keep your air cooler and fresher.

These are just two of the most common reasons why the AC unit in your home could be leaking. If your unit continues to leak, call a technician to come out and inspect your unit immediately.
