But there are many additional possibilities to think about before making a decision. For your convenience, we have covered them in this article.

Possible Reasons For Water Sounds From Window Ac

Refrigeration Issue

Have a look at the coolant in the refrigeration section. Lack of coolant may also lead to frozen coils. Whenever the coils defrost, they release excessive water, much like a filthy filtration might.

Cleaning or replacing the filters is the simplest solution to this issue. If it is not functioning, try cleansing the coils. However, gas leakage is a dangerous situation.

A Blocked Drip Pan

Evaporation may take place either manually or remotely in AC devices. The cooling process depends on how the device deals with the water. In an automated device, for instance, the water drops into a heated drip pan, where the heat accelerates the evaporation process.

The unit may condense faster during high moisture days than on another day. Moisture forms in the device and eventually drains out via the drainage pipe.

Rubber Stopper

Ensure that a rubber stopper does not block the outflow of the device. Remove this stopper and see if the water drains out more easily. When finished, plug back in and continue as necessary.

An External Source Of Water

There is also the problem of rainwater, which might contribute to the situation. Rainwater or any other kind of water may get on your air conditioner in an open area without shade.

Employ Drip Cushion

You can buy this cushion if the constant spilling noises are annoying. This cap fits above the AC unit and collects rain since it falls. Due to its velvety texture, the pad effectively muffles any background noise.

At the same time, audible noises will be muted relative to what you'd notice if the liquid drops straight onto the AC unit.

Air Conditioner's Direction

AC installed in windows needs a small incline to manage drainage properly. Its position may get changed during its maintenance.  Check whether AC is angled correctly.

Once you're done, ensure the issue has been fixed, and the accurate side of the air conditioner releases water by checking it several times while it's operating. The issue lies elsewhere if the system has been correctly positioned and water is still seeping inside.

Should You Worry If Listen To Water Noise Inside The Window Ac?

A window AC will chill the space by sucking in the hot air, running it via the interior coil, and then blowing the cooled air inside the space. Water splashing about in your AC is a normal occurrence. Despite its unsettling quality, the sound is very typical.

What If Ac Sounds Like It's Boiling?

A pressure problem is frequently the cause of strange noises from the interior AC. An excess of refrigerant is one potential cause of inappropriate internal pressure. Additionally, a leak in the refrigerant might be to blame.

Is The Sound Of Water Leaking From The Ac Normal?

Your air conditioner is designed to evaporate any excess moisture it absorbs partly. The trickling noises of water are common throughout the evaporation process. You may leave it alone if the water is not leaking from the AC.

Ac Is Making A Strange Gurgling Sound; What May Be Causing It?

If you hear gurgling, it's likely because of gas leakage. This gurgling sound you hear when the refrigeration has a leakage and air penetrates the region where the refrigerant has leaked.

Why Does My Air Conditioner's Window Unit Spray Water Into The Room?

The draining mechanism that transports the water from the air conditioner out of the house might get clogged with dust, grime, and other debris. It might lead to leaks in the system.


The different reasons behind the water sound issue are explained here already. However, please note that there are some serious issues that the experts only handle, so you should better call them at home.
