Why Is My AC Leaking Water?

Your air conditioning system is your best friend in the summer months when temperatures get so high that a simple fan probably won’t be enough to keep you comfortable. However, becoming increasingly reliant on the appliance means that you’ll be running it at an increasing frequency, and the more you run it, the more likely it is that you’ll have problems with it.

One issue that can be particularly distressing is if your AC starts to leak water. After all, its purpose is to cool the air inside the house down, so why would it spring a leak? 

Here are a few things that might be causing your AC to leak:

Clogged Drain Line

While the primary function of an AC unit is to cool the air down, it often ends up collecting water as a byproduct. Just like the droplets that form on a windowpane, when your AC unit pulls in air, it also gathers moisture on the evaporator coils. From the coils, the water collects in a drip pan that is eventually filtered outside via a drain line.

If your AC is leaking water, the first thing you should check for is a clogged drain line. Algae, fungus, and general pieces of debris can obstruct the flow of water and cause it to back up into your home. This is a relatively easy fix and entirely preventable with regular AC maintenance services

Frozen Evaporator Coil

A frozen evaporator coil is exactly what it sounds like: a piece of the air conditioner has become coated by ice due to some other issue in the system. With time, the ice can melt and fall outside of the drip pan designed to catch the runoff. When this happens, you’ll see water leaking from your AC.

However, the way to fix an evaporator coil that’s frozen is to resolve the issue that caused it in the first place. Simply thawing the equipment will help, but it won’t stop it from refreezing later on.

Low Refrigerant

One reason your evaporator coil might be freezing is due to a refrigerant leak. As a result, the pressure in the cooling system drops, which causes the temperature inside the machine itself to cool and ice over. However, if you do have a refrigerant leak, you want to call in a professional to make the necessary repairs.
