What Causes My AC System To Leak?

While it is summer, all you want to do is relax and make the most of your air conditioner. But, when disasters happen such as a leak in your cooling system, you suddenly find yourself rushing to know what causes it.

Stop making guesses! Instead, get to know these top reasons for air conditioner leaks.

  • Clogged Drain Line

One of the most common reasons for A/C leaks is a blocked drain line. Any blockage in the drain hole such as mold, insects, and dirt cause the water to go back into the system. Unclogging it may take time even when you use a high-performance vacuum. A quick way to unclog it and get your system back to work is to call professionals to suck the obstacle out.

  • Broken Sump Pump

If your A/C unit is installed in the basement, you can easily figure out why leaks happen. You can take a wild guess by thinking that the cause is a broken sump pump. And, you are right! Even the smallest crack on the pump prevents it from doing its job. Instead of pumping the water outside, it does the opposite. You might have it repaired or replaced depending on the severity of the damage.

  • Frozen Evaporator Coils

How is this possible when the sun’s all out? Leakage on air conditioners due to frozen evaporator coils is 100% possible because of clogged air filters. Dirt and dust that are accumulated in the evaporator coils block the air from passing through, causing the coil to freeze up. When airflow is constrained, ice will develop producing droplets of water over time. Other causes of freezing evaporator coils are damaged blower motors and blocked registers or vents.

  • Incorrect A/C Installation

Check your unit if it is positioned on the right spot or level. Doing this will assure you if your air conditioner is installed correctly (as required). Leaks can happen if installation is done in the wrong way. Let the experts do a complete examination on the system to guarantee a properly installed and designed A/C unit.

  • Excessive Pressure

Clogged or closed vents cause pressure to build up in your air conditioner. When there is too much pressure on the unit, water may begin to leak out. To avoid this scenario, make sure to leave your vents free from any blockage.
