Why Your Air Conditioner Is Leaking Water

Posted on

One of the most common problems homeowners face with their HVAC systems is a leaking air conditioner. While a little condensation is a part of the system’s normal dehumidifying process, puddles and/or large wet spots around the unit are not. Since any standing or leaking water in the home can lead to a number of additional problems, such as the growth of mold and mildew, these issues need to be addressed promptly.

Common Reasons for a Leaking Air Conditioner

There are a number of reasons you may have an air conditioner leaking problem in your Maryland or DC area home. Here are just a few:

  • Your pump is broken. If your AC unit is located in the basement or a lower level of your home, then it uses a pump to get the condensation water outside of your home. If that pump malfunctions, then you’ll likely find your air conditioner leaking.
  • Your system was poorly installed. If your ductless system hasn’t been installed properly, especially if the processing unit isn’t as level as it should be, water can drip unto the floor from the unit.
  • The drain is clogged. Virtually all air conditioners have a drainage system that funnels condensation away from the condenser and/or processor. If dirt or debris blocks this drainage route, the water will back up and collect in your living space.
  • It’s too cold outside. This may seem counter-intuitive, but when the outside temperature dips below around 60 degrees Fahrenheit, the water around your AC condenser doesn’t evaporate as it does in hot weather and will start to collect, potentially causing drips and leaks. It is best to turn off your system on chillier nights and switch it back on when it’s warmer during the daytime.
  • Your air filter needs to be changed. Dirty air filters seem to get blamed for a lot of HVAC problems. However, the truth is that many heating and cooling issues can be easily avoided by keeping your filters clean. A dirty AC filter restricts the air flow around your condenser, causing the coils to freeze and later drip.
