The 10 best air conditioners to buy in the UK
Finding the best air conditioner for your home will take some research, as there are various options available. A great air conditioner can efficiently cool a room or several rooms throughout your home, allowing you to feel more comfortable during those warmer weather conditions. The best type of air conditioner for one person may not be the best for another, as there are many things worth considering, such as how often it will be used and the climate of the area where you live in.
What are air conditioners?
An air conditioner is a machine that is used to treat the air in an enclosed space. It works by removing the warm air from a room and cooling it down and then redirecting the cooler air back into the room. This is achieved by running the warm air over chilled pipes inside the machinem, that are filled with a coolant fluid, cooling the air while a dehumidifier removes moisture, before a fan blasts the freshly cooled air back into the room.
Why should you buy a good air conditioner?
Buying an air conditioner is a great idea for many situations where a room or your entire home is excessively warm. Some people will only need this for a portion of the year, usually the summer months, while those staying in warmer climates may require one throughout the entire year. The benefits of owning the best air conditioner are quite obvious: the right air conditioner is great for cooling down a room when the heat makes it unbearable. This could be down to personal preference for a certain coolness in a room, but in many cases, it is necessary to make a home cool enough for comfortable living. For instance, if you live somewhere with extremely warm temperatures throughout the day, an air conditioning cools your bedroom more effectively than a ceiling fan, thus making it more comfortable to sleep.
How to choose the right air conditioner in 2025?
All the best air conditioners can quickly cool a room as desired, but as there are many types of air conditioning units available and not all of them will be best-suited for your personal needs. Therefore, it is important to know what to look for in an air conditioner in relation to your own circumstances.
Here are some things to look out for:
- Portability: A portable air conditioner is a great option for anyone that doesn’t require a permanent installation, such as those living in climates with cooler winters. This allows you to store the air conditioner when not in use, as well as making it easier to move from room to room.
- Noise: When an air conditioner is running, it can create a fair amount of noise, which may be off-putting in some circumstances, such as being used in a bedroom or office. Noise may not be an issue depending on the location, but it is certainly worth considering.
- Location: Where will your air conditioner be installed? For example, window air conditioners are popular but your window may not be in the most suitable location to effectively cool a room or you don’t want to sacrifice window space. Noteworthy, a through-the-wall unit is suitable for almost any room and can offer more cooling power in many cases.
- Installation: While the best air conditioners can effectively cool large rooms, they usually have to be installed, sometimes permanently, meaning you or someone else will be tasked with installing the unit. For those that don’t want to install anything, a portable air conditioner may be better than a window or through-the-wall unit.
What is the best kind of air conditioner in the UK?
There are a few notable types of air conditioner units available, all of which come with a variety of different features. Some air conditioners will be better suited for certain situations than others, so it is handy to know which one offers the most benefits for you:
- Portable Air Conditioner: The best air conditioner for someone looking for a flexible unit as they don’t have to be permanently installed. You can take it into any room, so be sure to consider weights if you plan on moving it around a lot. They blow hot air out through an exhaust, so an open window is required when using portable air conditioners. Very easy to install and a great air conditioner for anyone that doesn’t need it year-round.
- Window Air Conditioner: Offering a wide range of sizes and cooling options, window air conditioners are a good option for most households as they are affordable and effective at cooling single rooms. However, they will take up window space and are limited to one per room.
- Through-the-Wall Air Conditioner: Not unlike a window air conditioner, this unit is instead installed into a wall rather than a window. This makes them versatile options as they can be placed in any room throughout the home. Also, they do not require any window space to be sacrificed. Further, a through-the-wall air conditioner often has the best cooling capacity, making them better suited for cooling several large rooms.
