Why your Portable Air Conditioner Fills With Water Quickly and how to fix it


High Humidity in your space or room

Portable air conditioners work on a basic principle of cooling air by condensing the humidity in the room or given environment.  So, if there is high humidity in your room or area, you should expect your airconditioner to be generating more water than normal.

However once the humidity has been removed from your room, the rate at which water accumulates in your unit should normalize.

To maintain low humidity in your room, keep it closed so that air does not come from the other rooms or outside. You can also use the dehumidifier to remove the humidity in your room.

Newly installed portable air conditioner

Did you just  install the PAC  in the room or you have not used the PAC in your room recently? Then don’t worry because it is  not uncommon for it to fill with water quickly.

The good news is, it will stop producing much water when the humidity level in your room goes down.

This is because it has to start dehumidifying the room first especially if no air conditioner or dehumidifier has been used in the room recently. But soon afterwards you will notice that the number of times you will need to empty the water will  decrease.

Dirty air filters

Filters are there to ensure that only clean air enters your unit. However dirty or clogged filters will not only reduce the amount of air that enters your unit, they will also force your air conditioner unit to overwork.

When little or no air is able to enter your system, it does not reach over to the evaporation coils. when this happens, the air is going to freeze in your unit as a result of the moisture that builds up. So this will lead to an increase in the number of times you empty the water.

Dirty or clogged filters will also make your unit inefficient. Your unit will overwork to pull the air inside and  your room will not be cooled as much. So it is important that you check from time to time that your filters are in great condition.

Washing or replacing your filters also depends on your environment. Most manufacturers recommend replacing or washing your washable filters normally between about one to three months for your optimal operation of your unit.

 Using a faulty condensate pump

Sometimes you may be using a condensate pump to redirect the water building up from your unit.

However, when your pump is faulty or not working, you will notice that water will quickly start to build up and the number of times you need to empty it, will increase significantly.

Clogged  or blocked drain hose

Sometimes  you will notice that even after cleaning your air filters, you are still experiencing the quick filling up of water.

A common cause for this can be linked to a clogged or blocked hose. The best solution to this is to first remove the drain and carefully inspect the tank. If you notice any substance or clog that may be blocking the hose, you might want to clean it  to allow the hose to expel the water more efficiently.

Frequently asked questions(FAQs)

How do portable air conditioners drain water?

Well, different PAC drain water differently depending on the type and model of the PAC.

Generally speaking, there are three ways in which PAC drain water.

 newer or advanced models  usually drain water  automatically together with the warm air through the exhaust.

These are the models that are known as self-evaporating models. With such units you rarely or never have to empty the water manually.

Another  way the PAC deals with condensate water is through ‘gravity drain and condensate pump. With this method, you are required to attach the  drain hose to the drain port and direct it to the place of your choice

Then most commonly known, the manual removal. This is common with most traditional PAC which have buckets that are filled up with water periodically.

 Ideally you expect to empty the bucket from once in 8hours  to once a month depending on the humidity in your room or area.

To manually empty the water using the bucket, you first need to switch off the unit, then replace back the bucket before you turn it on again.
