A portable AC might be the best option for you if you live in the UK and can’t put in a window unit or full home cooling system because the summers are getting more and more unpredictable. Portable air conditioners are flexible, effective, and simple to set up. They are great for people who rent an apartment, have windows that are hard to reach, or just want a way to control the temperature on the go.
But not all portable air conditioners are the same. Some sound like jet engines, while others have trouble cooling a whole room. So, we’ve cut through the noise (literally) to show you the three best portable AC units of 2025. We’ve looked at things like how well it cools, how much energy it uses, how loud it is, and how smart it is, as well as extra features like heating or air purification. Let’s get started.
Midea Duo MAP14HS1TBL: Best Overall Performance
The Midea Duo MAP14HS1TBL is the best choice for quiet, steady, and strong cooling. This isn’t just another portable air conditioner; it’s a full climate control system that also works as a heater, so it can be used all year round in UK homes.
What makes it different? First, it has two hoses and an inverter compressor, which lets it cool a room faster and more effectively while staying very quiet. The temperature in the room stayed within 1°C during tests—no hot corners or weak spots. Plus, it works well with Alexa, Google Assistant, and its own easy-to-use app, so it’s just as smart as it is strong.
It has a built-in heat pump that lets it switch to heating during the colder months, which is a big plus. This is the best portable AC for you if you want a high-end one that will last for years and won’t need to be put away in the winter.
Best for: using all year, in bigger rooms, and for people who know how to use technology.
Frigidaire FHPH142AA1: The best quiet cleaner with purification
The Frigidaire FHPH142AA1 is the best choice if you want peace and quiet. We were surprised that this single-hose portable AC kept the room perfectly cool while making very little noise. It would be great for bedrooms or shared spaces.
One of its best features is that it can keep a temperature within half a degree. But besides cooling, it has a special bonus: it cleans the air. It can also work as an air purifier with an optional MERV-14 filter, which helps trap dust, allergens, and other pollutants. That is a big win for families with asthma or allergies.
It also has the ability to heat, which gives you even more options. The only problem is that the window-panel installation kit is a little clunky, but once it’s set up, this unit works well.
Best for: keeping things cool without making noise, people with allergies, and using it all year round.
Black+Decker BPACT14WT: The Best Cheap Option
Not everyone wants to spend a lot of money on an air conditioner, and that’s where the Black+Decker BPACT14WT comes in. This portable air conditioner is cheap and does the job without any extras. This one is worth thinking about if you want good cooling at a good price.
It cools well, but it’s louder and doesn’t have the smart features and sleek design of more expensive models. It’s perfect for people who just want to cool off without spending a lot of money. And even though it has some rough edges, like basic controls and louder operation, it works well in small to medium-sized rooms.
This Black+Decker unit could be the best choice for you if you’re new to portable air conditioning or just need something for a short time without spending a lot of money.
Best for: People on a budget, people who only need to cool down for a short time, and small rooms.
Last but not least, how to choose the best portable AC for your needs
As summer temperatures in the UK rise, having a portable AC becomes less of a luxury and more of a need. The market has something for every need and budget, whether you need a high-performance unit like the Midea Duo, a whisper-quiet purifier like the Frigidaire, or a simple budget model like the Black+Decker.
When choosing, think about the size of your space, whether you’ll use it all year, and if noise or air quality are important to you. You should also think about how easy it is to install and if you care about smart home integration.
Each of our top picks is the best in its category, and more importantly, each one gives you control over your comfort and the weather. Don’t worry about it this summer. Choose the portable air conditioner that works best for you and stay cool no matter what the British weather throws at you.
