Best Portable Air Conditioner For High Humidity And Humid Climates

While there are several ways to prevent excess humidity in your home, one of the best strategies is using the best portable air conditioner for high humidity.

Air conditioners work by blowing cold air into your room, removing both heat and humidity. That explains why these devices work better than dehumidifiers, especially in humid climates. Dehumidifiers only remove excess moisture but don’t cool the room.

However, not all air conditioners work efficiently in a humid climate. The best portable air conditioner for humid climates I have reviewed in this article has a dehumidifying component.

They will be able to keep your room cool as well as get rid of humidity and moisture. They are a little more expensive than other models, so be ready to spend a bit more.

Do Portable Air Conditioners Remove Humidity?

Absolutely! Portable air conditioners are a great alternative to consider when you want to dehumidify your space. Even if your home has a central AC unit, a portable AC can supplement cooling power when the central AC unit encounters temperature control issues.

For example, your upper floor rooms or bedrooms can get hot and uncomfortable during a hot day if they are not air-conditioned. 

Luckily, you don’t require any reconstruction with a portable air conditioner since it offers you the flexibility of moving from one room to another.

Since portable air conditioners cool the air efficiently, they can create a cooler living environment and help lower your home’s humidity levels. Cool air can hold less moisture compared to warmer air. Therefore, even cooling the air alone is one reliable way of reducing humidity. 

Which Mode Is Best for AC in Humidity?

The best portable air conditioner for high humidity can offer comfort and convenience during high humid climates. There are three distinct modes included in an air conditioner. They include:

  • Cooling Mode – In this mode, your AC turns on the compressor and pushes cold air into the room. However, the compressor immediately switches off when it senses that the desired temperature has been reached. The cooling mode is the most energy-intensive in your AC. The lower you set the temperature, the higher the amount of time the compressor will run.
  • Dry Mode – If you live in a humid area, a dry mode is the best option to consider setting on your air conditioner. When it’s a hot day, and you’re practically sweating, this is your go-to mode. It removes extra humidity in your room by cycling the compressor on and off for short periods of time. During this process, the fan is constantly running at a low speed. The compressor’s run-time is adjusted in that when the internal humidity sensor of your AC detects low humidity levels, it will turn off.
  • Heat Mode – When you set your AC to heat mode, the unit’s airflow is reversed. Therefore, this introduces hot air inside the room and ejects cold air. The compressor is the one that brings warm air.
  • Other modes are included in an AC, such as the auto mode, eco mode, and turbo mode, among others. 

Judging by the modes we’ve discussed above, the best mode for AC in humidity is the Dry Mode since it helps to remove extra humidity in your room. It also clears any sweat in your body and dampness in the surrounding room.

How Long Should a Portable Air Conditioner Sit Before Turning It On?

A portable air conditioner should only be allowed to rest for 30 minutes after moving it from one room to another. This also applies to any other refrigeration appliance that you may have in your home.

The main reason for this is because it will allow the fluids to settle into their places properly before you turn on the appliance. There is a higher chance of damaging the appliance or AC if you turn it on too soon. Therefore, it’s important to adhere to this recommendation strictly.

Is It Worth Buying a Portable Air Conditioner for High Humidity Areas?

Yes, it’s worth buying a portable AC in high humidity areas. However, consider supplementing it with a dehumidifier to have the best efficiency. This doesn’t necessarily mean that a portable AC cannot get the job done. 

When you set your air conditioner to Dry Mode, it can do a better job of removing extra humidity in a room and providing you with a comfortable environment. Also, unlike air conditioning systems, portable ACs should be vented in a way. They pull in warm air, cool it, and then expel it out of the room. 

Do You Have to Empty Water Out of a Portable Air Conditioner?

The simple answer is no – you won’t have to keep on emptying water from your portable air conditioner. This is mainly because, in most cases, your portable AC won’t need to be drained. Some portable air conditioners use a condensation exhaust system that collects water vapor during the dehumidifying or cooling process. 

The release of this moisture is done through the exhaust hose together with the hot exhaust air. However, when the conditions are extremely humid, the collected water doesn’t exhaust faster, which may fill the internal water reservoir. 

When such a case happens, your AC unit will shut off automatically to prevent overflowing the internal tank. This is the only time you will have to drain your AC’s internal water tank.

If you don’t want to empty your AC unit manually, consider using a self evaporating portable air conditioner.

5 Things to Consider When Purchasing the Best Portable Air Conditioner for Humid Climate

Here are some of the factors to consider before buying the best portable air conditioner for high humidity.


If you want to buy a portable air conditioner due to its flexibility and mobility, consider checking for one you can easily carry. You can do this by checking its weight and dimensions. This will help you determine whether you can easily move it from one point to another or fit it into your car.


Portable ACs are known for venting out hot air, and that means your unit near a window. Luckily, most portable air conditioners out there include a window venting kit and manual instructions on setting it up for venting properly. If you plan to keep your AC away from the window, you need to check the maximum width the window kit can extend to be on the safe side.

Energy Usage

Although it depends on how you use your portable AC, you are bound to see an increase in your energy use. Therefore, this is why you need to consider buying an energy-efficient portable air conditioner to avoid high electricity bills.


Is the AC you want to buy easy to install? If it is, then that’s a good choice. However, if you’re not sure, it’s best to ask, and while at it, ensure you find out whether there are clear instructions provided on how to install it in your room.

Room Size

What room size are you planning on using the AC, and will it be able to cool it efficiently. Ensure you buy a portable air conditioner suitable for cooling your room size without having to work too hard. Determine the size of your room in square feet and choose AC accordingly.

If you have a large room, you can still use portable air conditioners designed for large rooms but make sure it’s the right size so that it’s not overworking.
