Do portable air conditioners work? What are their advantages?

Summer is a season that many of us enjoy, but it can also be very hot and stifling. That’s why having a good home cooling system is essential for comfort and staying cool. However, it’s not always possible or convenient to install a fixed air conditioning unit due to space constraints, budget limitations, or permit issues. In such cases, portable air conditioners are an intriguing option that offers several advantages, which we will discuss in this article. But first, let’s address a common question: Do portable air conditioners really work?

What are portable air conditioners and how do they work? 

Portable air conditioners are devices that can be easily moved from one room to another due to their compact size and built-in wheels. They operate similarly to fixed air conditioners but with some differences. Portable air conditioners have a compressor that cools the air inside the unit and expels it into the room through a grille. Simultaneously, the unit absorbs the hot air from the room and expels it outside through a flexible tube, usually directed through a window or door. To answer the preceding question, YES, portable air conditioners do work as long as they are selected and used correctly.

What are the advantages of portable air conditioners? 

Portable air conditioners offer several advantages over their fixed counterparts. Here are some of them:

No installation required

They simply need to be plugged into an electrical outlet and have the exhaust hose directed outside. This saves significant time and money, as there’s no need to hire a professional to carry out an   installation .


 They can be used in different rooms according to your needs, allowing for efficient energy consumption and adapting to changing climatic conditions. For example, you can use them in the living room during the day and in the bedroom at night.

User-friendly and easy maintenance

Most models come with a simple and intuitive control panel, featuring functions such as a timer, night mode, or remote control. Additionally, maintenance is minimal, usually involving regular cleaning of the filter and emptying the water reservoir if applicable.


Portable air conditioners consume less energy compared to fixed units, resulting in reduced greenhouse gas emissions and a smaller environmental footprint.

Factors to consider when choosing a portable air conditioner

When purchasing a portable air conditioner, several important factors should be considered to ensure the best fit for your specific needs. Here are some key considerations:

Cooling capacity

Measured in BTUs (British Thermal Units) or kilocalories, the cooling capacity determines the unit’s effectiveness in cooling a given space. Higher cooling capacity results in faster and more efficient cooling but may also lead to increased energy consumption and noise levels. It’s recommended to select a cooling capacity suitable for the size and orientation of the room where the unit will be used. Haverland UK offers a wide range of options to meet your specific requirements, such as the IGLU 0723 for rooms up to 18 m² and the IGLU 0923 for larger spaces up to 22 m².

Energy efficiency

Energy efficiency is indicated by a label ranging from A+++ (most efficient) to D (least efficient). Higher energy efficiency translates to lower energy consumption and reduced environmental impact. Opting for a model with high energy efficiency can lead to significant savings on electricity bills. For example, our low-consumption portable air conditioner, IGLU UV7, falls into this category.


While not the primary consideration, the design of the unit can play a role in the decision-making process. Different models offer varying aesthetics, colors, sizes, and weights. Considering the unit’s size and weight is essential for mobility and storage purposes.

Additional features

Some models come with extra features that can be beneficial, such as a dehumidifier mode, fan mode, or the silent mode of IGLU 9.

Maximizing the performance of portable air conditioners 

To maximize the performance of portable air conditioners and create a cool and healthy environment, it’s important to follow some practical tips, including:

Positioning the unit properly

Ideally, place the air conditioner near a window or door to allow for the expulsion of hot air outside without obstructions. It’s also important to avoid direct sunlight and keep the unit away from heat sources such as radiators or appliances.

Adjusting temperature and airflow

Setting the air conditioner to maximum power or the lowest temperature isn’t necessary, as it can result in discomfort and inefficiency. It’s recommended to adjust the temperature between 24 and 26 degrees Celsius and the airflow according to personal preferences.

Ensuring room insulation

To prevent heat from entering the room and cool air from escaping, ensure that windows, doors, and blinds are properly sealed. Curtains or awnings can also be used to block solar radiation. These measures help maintain a comfortable temperature and reduce energy consumption.

Regular cleaning and maintenance

To ensure optimal functioning and prolong the lifespan of the portable air conditioner, regular cleaning of the filter every two weeks or so is necessary. Additionally, emptying the water reservoir when needed and checking the condition of the exhaust hose and compressor are important. Referring to the user manual for any questions or issues is recommended.


The effectiveness of portable air conditioners is also influenced by the energy efficiency of the home

The energy efficiency of a home refers to its ability to optimise energy consumption, reduce losses, and minimise emissions. Therefore, for portable air conditioners to function properly, it’s important to have adequate thermal insulation, suitable climate control systems, and responsible consumption habits. Portable air conditioners can contribute to improving the energy efficiency of a home by following these guidelines:

Choosing a model with high energy efficiency

As mentioned earlier, more efficient models consume less energy and emit fewer greenhouse gases. It’s crucial to consider the energy label of the unit before making a purchase.

Using the air conditioner only when necessary

There’s no need to keep the air conditioner running all day or in every room. Ideally, use it only when people are present in the rooms being occupied. Additionally, setting the timer to automatically turn off the unit when not needed can be beneficial.

Combining with other cooling methods

Portable air conditioners are not the sole means of cooling a home. Using fans, curtains, awnings, plants, or reflective paint can help reduce temperature and energy consumption.

Maintaining a reasonable temperature

Setting the air conditioner to an excessively low temperature is unnecessary and can be detrimental to health and the environment. It’s recommended to maintain a temperature difference of around 5 degrees Celsius between the inside and outside of the house.
