Help! Why Is My Split A/C Leaking?

As all Texans know, a working air conditioner is essential to total home comfort. For many homeowners, a split air conditioner is the best way to achieve this. Split AC systems have two units, one of which goes inside, and one which goes outside. If you hear people referring to their central AC, chances are they’re talking about split units.

Split AC systems have many advantages, including the fact that they are generally more energy-efficient, and tend to make less noise. However, like all air conditioners, split ACs are not above springing a leak. Keep reading to find out why your split AC is leaking—and what you can do about it. And remember, for comprehensive AC service and repair, trust the Fredericksburg and Kerrville experts at 72 Degrees Air Conditioning & Heating.

5 Reasons Your Split A/C May Be Leaking

  1. Your Air Filters Are Dirty: Anytime you switch off your split AC system, the unit inside your house absorbs heat and humidity. The unit then pulls moisture from the air and drops water into the drip pan, However, if your unit’s air filters are dirty, they will prevent airflow, causing those droplets to freeze. And of course, when droplets freeze inside the unit, they will eventually melt, leading us back to the cause of your leak. Fortunately, the good news is here that this problem is fairly easy to correct—most often you just have to change your filter. How often this is required depends on factors like how much pet dander or other debris is floating around your home, and whether anyone in the house has allergies. In the event that your filters are reusable, they should be taken out, washed, and left out to dry for 24 hours before being put back in.
  2. Your Drip Pan Is Rusted/Cracked: As we mentioned above, the drip pan in your split AC system is used to catch water. Over time, this equipment may become rusted. When this happens, cracks and fissures can occur, preventing the pan from doing its job, and causing the system to leak. You can check to see if this is the case with your system at some point when you are not using it. If it is, you should be able to unscrew the old drip pan and replace it with a new one. Or feel free to call our AC installation pros, who will be happy to do this for you.
  3. Your Condensate Line Is Clogged: Your split AC dispenses the water in the drip pan through a pipe called the condensate line. This piece of equipment is dark and moist, making it the perfect place for mold to grow. When this happens, the line can become clogged, backing the unit up, and causing water to leak out. It’s a good idea to regularly flush out your condensate pipe to prevent this from happening. In most homes, you can find the line outside, near the other half of your split system, called the condenser unit (in apartments and condos, the condensate line is often located in the furnace closet.) One helpful tip: rather than flushing the unit out with water, which may not be as effective at removing mold, consider using vinegar instead.
  4. Your Condenser Pump is Broken: The condenser pump is the piece of equipment in your system which flushes water out through the condensate line. Much like the line, when the pump breaks down, the result can be a leak in your system. If you suspect your condenser pump may be the issue, consider calling a technician and scheduling regular maintenance, so this doesn’t happen to your AC system again in the future.
  5. Your Equipment Is Faulty: Unfortunately, there are a lot of things that can go wrong with your split AC system. If your equipment is old, worn out, outdated, or if it was installed improperly, there’s a chance it may break down, causing any number of leaks.
