Finding The Drain Hole On A Window Air Conditioner

Wondering, “where is the drain hole on a window air conditioner?” Worry not; this section will be talking in regards to that.

Air conditioners, usually window types, have drain pans in the bases of the cooling unit. The water inside it will fill up and flow into a drain. Finding the drain hole is only an easy task. First, you need to access your air conditioner from the exterior of your home.

Then, find the drainage hose of your window air conditioner. Follow the drainage hose to the drain pan of the cooling unit. There it is! What you had recently found in the drain hole itself. Some window air conditioner units have the absence of a drainage hole in the back of the unit.

If so, you will only be looking where the water is dripping when the air conditioner starts working. That spot will probably be the drainage hole. When these spots do not work, it is best to get in touch with your air conditioner and tear it down.

You will see the drainage pan and the drain hole when the window air conditioner is disassembled. If your window air conditioning unit does not come with a drain hole, do not worry.

Manufacturers have sometimes excluded the drain hole to their units for a reason. This reason is that the window air conditioner itself has a unique part called the slinger ring. Likewise, this part is installed on the rear fan blade.

As the fan blade rotates, the slinger ring will gather the water from the drainage tray and move towards the air conditioner’s condenser coils. Through this, your window air conditioner will utilize the residual water in cooling the interior coils of the unit cool enough.

With cooling coils, the air conditioner unit will be running more effectively and can avoid overheating. Most importantly, it would help if you were opening the drain hole of your window air conditioner most of the time.

If not, the residual water gathered by the air conditioner will overflow and can damage the cooling unit. It can also contribute to the oxidation of the interior parts and produce rust, which can be very bad for your air conditioner.


Why Do Our Window Air Conditioners Produced Water?

Do not fret if you have noticed your air conditioners having water when it is in operation. It is very natural. Our air conditioners cool our room through the refrigeration process. This process involves two coils that are placed inside your air conditioner.

The two coils are both hot and cold. Cooling coils will be absorbing moisture from the air. The same phenomenon when you have your cold drink produces water in the glass.

When the cold coils interact with the absorbed air, the air that has moisture will produce water through condensation. Other amounts of the water will evaporate again, keeping the inside coils cool for it to operate.

The excess water from the system will be draining out from the air conditioner itself. As a result, you will be seeing water dripping from the outside of your air conditioner.

Thanks to the process, air conditioners that produce water when operating are good signs that it is healthy and stable. If not, air conditioners that do not drain water from the back holes can have serious problems that need repair. Other problematic air conditioners that do not drip water will have their coils freeze up—another problem.

Hence, you need to check your air conditioner periodically if it drips water or not. For example, it might have clogged drain holes or frozen coils. You can call your nearest air conditioner service repair if you cannot diagnose the problem with your cooling unit.
