Portable Air Conditioner Not Evaporating- How Do You Get Around This?

A portable ac unit will generate some water vapor while cooling. Self-evaporating air conditioners also remove the excess moisture from the air while evaporative cooling. A portable air conditioner like this will condensate the indoor air quickly. It is possible that the portable air conditioner will evaporate the water quickly too.

However, the problem arises due to portable air-conditioner-not-evaporating. Below is a list of the problems that have we can see in air conditioning systems.

How does a self-evaporating portable air conditioner compare to a standard portable ac?

A typical air conditioner or unit does more than cool air in a small space. In fact, it removes moisture from the room. This is one of the reasons why people choose to use air conditioners over other cooling methods.

An evaporative cooler removes the warm air from the room. It makes the room much cooler. It reduces high humidity and excess moisture from the air.

However, with typical portable air conditioning units, the moisture (water vapor) comes from the warm air. This liquid should drain. As a result, an auto evaporation system makes sure to drain the liquid.

A portable ac does not require a drip or drain pan at all. Excess water from the space is simply treated (evaporation or dispersion). Then it cools the interior components. The remainder discharges into the atmosphere by a hose.

Self-evaporating air conditioners

A self-evaporating portable air conditioner is also a “no-drip” cooling machine due to this process.

Having a portable self-evaporating air conditioning unit has many other advantages.

Other than periodic drainage through an exhaust hose or a dual hose, there is no other maintenance required.

The chances of auto-shutdown are also less while using a self-evaporating portable air conditioner.

The air is dry and clear of moisture.

The cooling is more precise and steady all the way through. Moreover, a btu may show how much energy is there to remove all the moisture or heat.

What Are the Reasons for a Portable AC Filling with Water Quickly?

There are several reasons that could contribute to your AC filling with water too quickly. Let’s have a look at some of them.


Your area could have a lot of humidity. The condensation of humidity from the air generates water in your portable air conditioner. As a result, the amount of water it produces is proportional to the humidity in the air.

More water will collect in the condensate pan of your portable air conditioner. This will happen if you reside in a humid environment. If you live in the most humid city in the world, there will be more condensate inside your condensate pan.

Most portable air conditioners are primarily evaporative. So you may never have to worry about condensate in these cities. The reason for this is that much of the moisture that has is automatically expelled.

If you’re considering purchasing a portable air conditioner, think about which model is ideal for you. If you live in a low-humidity area, you may utilize a portable air conditioner without self-evaporative technology. This is because you won’t have to worry about repeated drainage.

To minimize constant interruption and annoyance, utilize a partially evaporative or fully evaporative portable air conditioner in excessively humid areas.

Filter with dirt

After passing through an air filter, the air-cooled by your portable AC circulates in your room. The air goes through filtering to remove dust and debris. After a certain number of hours of cooling operation, you should clean the filter. The length of such time depends on the quality of air that goes through it.

A filthy filter is one of the reasons why your portable air conditioner keeps filling up. The air flowing out of your portable air conditioner won’t come out if the filter becomes clogged. The airflow rate will lower, resulting in less air passing over the evaporator coil.

As a result, the moisture in the air freezes on the evaporator coil. This causes it to drop into the condensate pan. Even if you have a partly evaporative portable air conditioner, the water will not collect at the same pace as it drips. So, you’ll have to constantly empty it.

You’ve Purchased a New Portable Air Conditioner

If you’ve just bought a new portable air conditioner, it may leak a lot of water. It’s quite unlikely that it’s due to a technical issue. The reason for this is that when it comes to marketing air conditioners, corporations are quite concerned about their reputation.

Since there is so much competition, they cannot afford to damage their reputation. Unless the damage or problem with the air conditioner occurred after delivery, you can return it and get a new one.

The cause for the problem might be the high relative humidity in your location. But it could also be due to the fact that you recently purchased a new unit. After a time, when you air condition your living space, the humidity is not there in the air. This might lead to a lot of water accumulating in the water pan.

So, if your water pan continues filling up while testing your new portable air conditioner, give it some time. If it keeps filling up, it’s maybe because the air conditioner breaks often. It could be that the air conditioner is not designed for the climate you live in.

This is because the climate has a high average relative humidity. As a result, you may wish to look for a different type of portable air conditioner. You may look for a partially evaporative or totally evaporative unit.

Faulty Air Condensor

Setting up a condensate pump is a simple technique to completely eliminate condensate. Normally, a condensate pump transfers the water that has accumulated in the water pan. It is pretty simple to set up.

You may have a condensate pump where the water tank is constantly filling up. Then there is certainly an issue with the condensate pump arrangement. The condensate pump could be malfunctioning. It could be that the drain line entering or exiting the pump has blockages or bends.

What Should I Do If My Portable Air Conditioner Is Not Evaporating Water?

The discharge of surplus water through a hose during the chilling process is one of the most important features of a portable air conditioner. There is no longer any requirement for a good drainage system though.

However, if the weather conditions are not favorable, difficulties with the air cooler may arise.

Condition of the weather: Check the humidity level

The first thing you should know is what we mean when we say “suitable weather conditions.”

The relative humidity should be average when we say that the weather condition is good. In most cases, humidity levels of 20-25 percent in the winter are common. 50-55 percent humid air is alright for summer. Keep in mind that this is a yearly average keeping all factors such as the air flow in mind.

However, if the humidity levels are higher, then the portable units could function differently. This is also a symptom of uncomfortable or unsettling weather.

So, what happens in this kind of weather?

If you use a portable air conditioner in such humid circumstances, your portable air conditioner may shut off automatically.

The quick filling of the water reservoir is one of the main reasons behind this.

Normally, the inner water reservoir does not fill up so rapidly. However, in extreme circumstances, it may fill up faster than you think.

Short-term and long-term methods for draining excess fluid

If you’re dealing with an issue like this where there are condensation problems in your air cooler, then you definitely need to read about these solutions.

You have two options for dealing with the problem. The first strategy is a short-term one.

Short-Term Strategy

This is a simple way to get rid of extra condensate liquid.

The first step is to collect a bucket.

Find a basin or bucket large enough to hold the surplus water or condensate. You could drain it without a bucket as well.

However, we would advise emptying the bucket properly.

Step two is to locate the single hose for proper drainage of the condensate.

For this stage, you may wish to take references from the handbook.

Each seller will almost definitely provide instructions on how to use the drain port effectively.

Step three is to empty the reservoir and open the port.

All that’s left to do now is open the port and drain the reservoir. Again, attempt to do it in a controlled manner to avoid water spilling everywhere.

The Long-Term Strategy: To completely solve the problem

Maintaining the operating integrity of your portable air conditioner requires a long-term strategy.

The first step requires locating a drain port that is adequate.

You must locate a drain port that is compatible with the drain port on your air conditioner.

You may purchase this from any nearby hardware shop. Finding the ideal match, on the other hand, may need a little more searching.

Step two is connecting the two ports together.

The drain port must now connect to the air conditioner port.

Step three is to finish with a water-tight hose.

Install a suitable hose at the drain port’s end. The drainage endpoint’s length will connect to the length of the hose.

Step four is connecting the drain hose to the drain.

Finally, choose a safe drainage location and place the drain hose’s end there.

This ensures that any surplus water is instantly evacuated through the port. As a result, you will no longer need to bother with the water reservoir.

Final Words

There are a few options for fixing a portable air conditioner that isn’t evaporating water. These are there in this article.

However, the question is which option is more effective. Fixing the problem is a long-term investment.

Even if you don’t mind emptying the water on a regular basis, the long-term solution eliminates the inconvenience. As a result, there’s no need to waste time emptying the water reservoir or dealing with automated shut-offs.

We’ll let you make the ultimate decision. For the time being, let’s end here.
