Do I Need To Drain My Portable Air Conditioner ?

In general, portable air conditioners should be drained after every 8 hours. The frequency varies depending upon the model you own. Few air conditioners work efficiently without draining for a month. If you stay in a dry area, you would rarely have to drain your air conditioner. Most portable air conditioners are designed to be self-evaporate, which means they typically do not require manual draining. They are equipped with a condensate system that cools down the condensate and recycles it to enhance the cooling efficiency. However, in high humidity conditions or during prolonged use, some portable air conditioners may produce excess condensate that needs to be manually drained.

What happens if you don’t drain the water from a portable air conditioner?

If you don't drain the water from a portable air conditioner when required, it can lead to several issues. Untimely drainage of air conditioners leads to overflowing of the condensate tank. This can result in water leakage, damaging your floors or furniture. Additionally, stagnant water can create a breeding ground for bacteria, mold, and mildew, which can negatively impact air quality and potentially cause health issues. Furthermore, the unit's cooling efficiency may decrease if the condensate system becomes clogged or overwhelmed, affecting its overall performance. Therefore, it is important to follow the manufacturer's instructions and regularly drain the water when necessary.

How do I drain my portable air conditioner?

Portable air conditioners need regular maintenance to function properly. Among them, draining the condensate tank is an important task to keep your portable AC running.


3 Ways How To Drain Portable Air Conditioner?

  1. Empty The Condensate Tank Manually:

If you happen to have an old portable air conditioner, chances are it has a detachable condensate tank. While a part of the moisture collected will evaporate outside, some of them will be left in the tank.

A portable air conditioner’s water tank is very similar to that of a dehumidifier, which has a water level sensor. When it is full, the machine will automatically shut down. Some models include an indicator that alerts you when it’s time to empty the tank.

To drain the water in the tank, turn off the machine and remove the tank. The water should then be drained into a floor drain or a sink. When finished, replace the tank and restart your machine.

  1. Drain In A Pan:

    Portable air conditioners have a drain plug on the back. When the plug is unplugged, water will come out of it constantly. you should prepare a big pan and place it under the drain plug. please unplug your device before starting. Now you can open the drain plug and allow the water to drain from your portable ac freely. When all the water runs out, replace the plug and turn on your device again.

    Note (The pan should be quite flat to be able to be placed under the drain plug. Otherwise, you need to place your ac on a higher level, like a big stool.)

  2. Drain Water Through A Condensate Pump:

    Certain portable air conditioners come with a built-in condensate pump. The water can drain almost anywhere with the help of a condensate pump. There are two hoses connected to the pump rather than one. The first is to connect the portable air conditioner, and the second is to send water outside the window or down the floor drain. It will begin to draw water automatically once the water level in the ac reaches a certain level. While it may be a bit pricey up front, it will save you a lot of time and effort in the long run.

How often do i need to drain my portable AC

Portable air conditioners need regular maintenance to function properly.
Even you will need to drain your portable air conditioner as often as every 8 hours. The frequency of drainage depends on various factors such as humidity level, room temperature, and the size of the ac unit. 

To determine the frequency, you need to check the water tank daily, especially during peak summer days. If the water tank is half full or more, it’s time to drain the unit manually. Some portable AC’s come equipped with automatic draining systems that eliminate the need for manual draining. 

If your unit has this feature, you can set it up according to the manufacturer’s instructions. Proper and regular draining of portable AC’s enhances their efficiency and prolongs their lifespan.


Why does my portable AC have two drains?

Portable AC’s have two drains for condensation removal. One drain is for excess water to flow out while the other is for draining efficiently. Using both drains will prolong the lifespan of the ac, keep it working efficiently, prevent mold growth and damage to flooring and walls.

Can you drain a portable air conditioner into a bucket?

Yes, you can drain a portable air conditioner into a bucket. If your portable air conditioner does not have a built-in drainage system or you prefer not to use it, you can manually drain the condensate into a bucket or shallow pan. Position the bucket beneath the drain outlet or remove the drain pan and pour the water into the bucket. Ensure that the bucket is large enough to hold the amount of condensate and is placed securely to avoid spills or accidents. Regularly monitor the bucket's water level and empty it as needed to prevent overflow.
