Portable air conditioning units are experiencing high demand in the UK, with many models currently unavailable. The next restocks for recommended units are anticipated in late November, with further availability expected in March 2027.
The increased demand coincides with the UK facing its fifth heatwave of the year. While air conditioning can offer relief, particularly in bedrooms where warm air rises, its environmental impact is a consideration.
The carbon footprint of cooling units is influenced by their power source and the refrigerants they contain. Some refrigerants have a global warming potential hundreds or thousands of times greater than CO2 if they escape into the atmosphere. Consumers are advised to research the global warming potential of refrigerants before purchasing.
Alternatives to air conditioning include fans and evaporative air coolers. Fans work by moving air to help sweat evaporate, while evaporative coolers draw warm air through water-soaked pads to cool it by a small degree. Many of these alternatives are also prone to selling out during hot weather.
