Portable air conditioners are popular for cooling small spaces such as apartments, bedrooms, and offices. They are affordable, easy to install, and provide efficient cooling, making them popular among people who cannot install permanent air conditioning units. In this article, we will provide you with tips on how to maximise the cooling power of your portable air conditioner.

Choosing the Right Size

If you buy a unit that is too small for your room, it will need help to cool the space effectively, while an oversized unit will consume more energy than necessary, leading to higher electricity bills. To determine the correct size of your portable air conditioner, measure the dimensions of your room in square feet and match it with the unit’s BTU (British Thermal Units) rating.

Placement of the Unit

The placement of your portable air conditioner plays a significant role in its cooling efficiency. Ideally, place the unit in a shaded area, away from direct sunlight, as sunlight can heat the room and make the unit work harder to maintain the desired temperature. You should also place the unit near a window or a door, where the hot air can be vented quickly. If you place the unit in a corner or a closed room, it will not be able to circulate the cool air effectively.

Cleaning the Filters Regularly

The filters in your portable air conditioner are responsible for trapping dust, dirt, and other particles that can affect the air quality in your room. If the filters are dirty, the unit cannot circulate the air effectively, and the cooling power will be reduced. Therefore, it is essential to clean the filters regularly. You can do this by removing the filters from the unit and washing them with soap and water. Make sure to dry the filters completely before putting them back in the unit.

Using a Fan to Circulate the Air

Using a fan with your portable air conditioner can help circulate the cool air around the room. This is especially useful if you have a large room or want to cool down a specific area of the room. You can place the fan near the air conditioner and direct the airflow towards the areas that need more cooling. This will help distribute the cool air more evenly and reduce the air conditioner’s workload.

Using Curtains to Block Out the Sun

Sunlight can heat up your room and make your portable air conditioner work harder to maintain the desired temperature. Therefore, it is a good idea to use curtains or blinds to block out the sun during the hottest parts of the day. This will help keep your room cool and reduce the air conditioner’s workload. Consider using reflective window film, which can reflect the sun’s rays and prevent them from entering your room.


Portable air conditioners are an excellent way to cool down small spaces, but you need to use them correctly to get the most out of them. By choosing the right size, placing the unit in the right spot, cleaning the filters regularly, using a fan to circulate the air, and using curtains or blinds to block out the sun, you can maximise the cooling power of your portable air conditioner and enjoy a comfortable and cool living space.
