Most of the time, people rarely give their air conditioners much thought until there is a problem and it needs troubleshooting. One common problem with air conditioning unit is they end up leaking water inside. If your air conditioner has this problem, then here is some information you should know about the cause, and how you can fix it.

Humidity in the Air

Humidity is the amount of water in the atmosphere. The function of an air conditioner is to remove the moisture in the air. This then reduces the humidity levels in your home and can be the cause of the water you see “leaking” from your unit.

Generally, your air conditioner producing water is a good sign – you’ll likely see the water draining out of the back of the AC unit outdoors. However, if water is not draining here, then there might be a problem – like it is draining where it shouldn’t or is clogged in your unit.

Causes Of Leaking Air Conditioners

Air conditioners usually produce water as part of their operating process. It comes out of a specific drain line. However, if the water is coming from somewhere else, then your air conditioner is leaking and will need fixing. Some of the causes of a leaky air conditioner include:

  • Clogged Drain Lines

Air conditioners produce a lot of water, and they usually discharge it down the drain line. If the line is clogged, the water will end up backed-up inside. A clogged drain line can cause water to leak out of other areas. If your air conditioner is leaking water indoors, the first thing you want to do is unplug it (water and electricity don’t mix). Next, you’ll want to inspect the drain lines and clear out any debris that may be clogging it. Once it has been cleared, turn your unit back on and see if the issue resolves itself. If not, troubleshoot with another possibility below or contact an AC repair company, like C&S AC Services to help you get your air conditioner back to normal.

If you have a really old unit that is still going, it may drain into a pan. Check to ensure the pan has not rusted or damaged as these effects can cause leaking.

  • Icy Coils

If the water is not draining properly, it can back up over the cooling coils. As a result, the water freezes over the coils. To check for this use, turn off your unit and open the cage to inspect the coils. This can be complicated for homeowners unfamiliar with their AC unit – if so, give us a call to solve your leaking air conditioning issue.

  • Dirty Air Filter

If it has been several months since you changed your air filter, it could be the cause of the AC leaking.  When the air conditioning’s air filter is dirty, it inhibits proper air flow over the evaporator coils. As a result, the coil gets too cold and freezes – and when it thaws, it leaks.
