Air Conditioning Drain

Do you know what the air conditioning drain is? It’s the famous syringe. In this post, we check how the drainage of the air conditioners works and give tips to install the drainage in the air conditioners. We will address the three most common models, which are: Window, Split Wall and Ceiling Floor. Each computer has a way to drain water, so it’s important to keep an eye on your device.


Air Conditioning Drain: What is it, what are the types and problems?

What is the drain and what it’s for

In air conditioners, drainage is responsible for removing water produced by the appliance. During operation, the equipment removes moisture from the environment in which it is installed, performing the condensation process, which is when water passes from steam to liquid.

Each air conditioner has a drainage system, no matter the type. It is usually a tube that comes out of the lower corner of the device. This outlet can be connected to a hose to direct the flow, below we show you the most correct way to place this exhaust.

The water coming out of the drain is not drinkable, but it can be reused in a very creative way, you can even generate a profit! It is also not common for drainage in the air conditioning inside, to know how to solve the internal drip.


Problems that can cause drainage

Common air conditioning problems can originate in the drain. That is, if it is not in the correct condition, it can cause dripping into the indoor unit, loss of efficiency of the unit and even a bad odour in the environment in which the air conditioning is installed.

If bad care was extreme, we can have infiltration into the systems and even crashes into the equipment. It is very important to dispose of drain water properly.



Window drain

The drain in the window models consists of a small hole on the outside of the appliance, which serves to expel condensed water. Normally, the window air conditioning drain does not move, except when water droplets fall on a tent or sidewalk.

If this happens, it is necessary to provide a drip tray or conduit to redirect the liquid to the appropriate location. Dripping in these areas can damage building structures and create slime in the streets, causing pedestrian accidents.


Dry Air Conditioning Drain

Some window model air conditioners have the option of dry drainage. This function does not cause dripping outside, as it captures condensed water in a tray inside the unit. When the tank is filled, the propeller is responsible for splashing the water into the condensation chamber coil, which in turn evaporates the water by its high temperature.

This process of internal evaporation of water, in addition to eliminating dripping in the street, helps in the performance of the device, cooling your system. However, some users complain about dry drainage, because the propeller makes a lot of noise when in contact with water. To deactivate the function, simply open the drain cover (rubber gasket), located behind the device. In this way, the water is drained without making noise.

Manufacturers claim that dry drainage ensures energy savings because it aids in the thermal exchange of equipment.


Wall Drain

In these two types of split air conditioning, drainage is done by means of pipes. It is necessary to carefully observe the place where the drain will be installed. In this equipment, the drain leaves the internal unit (evaporator) and is directed to a rainwater point. It is not indicated to drain water into drains or sewers, as when the brake is turned off it may end up “bringing” the bad smell to the environment.

In the indoor unit, it is recommended to use the right side for the outlet of the drain, while the other tubes are on the left side of the evaporator. Gravity is responsible for removing water from the wall and ceiling, and therefore the water leak cannot be tilted or clogged. In some cases, the installer needs to provide a siphon to expel the water.


Drain maintenance

When maintaining air conditioning, also check the drainage system of the equipment. The water outlet in the tray is usually obstructed by dried leaves, contamination and other objects.

In split models, the drain pipe can become irregular or clogged, causing dripping into the environment. If the user wishes, there are devices that are installed next to the air conditioner to evaporate the condensed water, without the traditional drainage system.


Learn how to install an air conditioning drain

To avoid dripping and take advantage of the water generated, we have created a simple step by step that you can make yourself.

Step 1

Check the drain outlet nozzle of your air conditioner. If it’s split, it’s easier, because the hose will already be there, just choose a suitable container for the type of use you’re going to make. If it is a window device, check if you have a coupling hose, they have multiple equipments.

Step 2

If the appliance has the coupling, simply choose the appropriate hose and thread. If you don’t have it, measure the outlet nozzle to know the ideal width the hose should have. A 1/2 inch hose is usually used. But it has to be of good quality, offer resistance, because it will always be exposed to the weather. If you think it’s better, cover the entire hose with insulating tape.

Step 3

Ideally, attach the hose to the drain with a circular clamp and tighten the screws with a screwdriver.

Step 4

Choose a container so that the water drains, preferably with a lid at the other end of the hose. Or, if you live in an apartment and can’t leave the container outside, drill a hole as thick as the hose and direct the water into the apartment. In this case, the attention should be greater as the container fills up, so as not to run the risk of wetting your furniture.


Here are some ideas we find on the Internet

This installed a wide PVC pipe with a tap attached to the tip, gives a little work, but with the step by step, it becomes easy to do…

That left the horse loose in a bucket, much simpler and simpler.

He cut a few 20-litre drums, put them together and put them on a faucet.

He used a beverage cooler with only the hose placed inside.

So, is there any doubt? Drainage is an essential part of air conditioning and should be properly administered. Damage can be irreparable for your device if you don’t open your eye. If in doubt, call a technician.
