Air conditioners: heatwave leads to record sales

2.7.2025

Translation: Patrik Stainbrook

The heatwave has hit Europe, kicking off a boom in mobile air conditioners. Galaxus has never sold as many air conditioners in one month as it did in June 2025. Affordable models under 300 francs/euros are particularly popular.

While Europe’s suffering from sweltering heat, manufacturers and air conditioning system sellers are doing great business. Online retailer Galaxus has sold more than three times as many air conditioning systems this June as in June 2024 (+233 per cent). In the first half of the year as well, more devices were sent to customers than in the entire previous year. «I’ve never seen a boom like this before,» says Daniela Sanzoni, who’s responsible for the air conditioner range at Galaxus. In Switzerland alone, Galaxus customers bought a five-digit number of air conditioning systems in the record month of June.

However, customers are still reluctant to make pricy investments in air conditioning in 2025. At 377 francs/euros, the average sales price per appliance is just 10 francs/euros higher than in the previous year. «Air conditioning systems between 200 and 300 francs or euros are particularly popular with us at the moment,» says Daniela.

Air conditioners can be divided into four types: air coolers, mobile monobloc air conditioners, mobile split air conditioners and fixed split air conditioners. Air coolers provide a slight cooling effect through water evaporation. They’re affordable and save power, but only effective at low humidity levels. Mobile monobloc air conditioners are compact appliances with exhaust air hoses that direct warm air outside. They’re mobile and easy to use, but usually noisy and less efficient. Mobile split air conditioning systems consist of indoor and outdoor units. Like monobloc systems, they don’t require fixed installation. However, they’re more powerful and quieter than monoblocs. Fixed split air conditioning systems are permanently installed systems with indoor and outdoor units. They’re comparatively efficient and quiet – ideal for home and flat owners looking for a long-term solution.

Mobile monobloc appliances that can be stored away in the cellar after summer ends are still the most popular with Galaxus customers in 2025. Still, a new trend is emerging: more and more customers are turning to mobile split appliances. By now, 8 out of 100 air conditioners ordered from Galaxus are mobile split units. They’re quieter and more powerful than monoblock appliances, but generally more expensive too. Expensive, permanently installed systems, on the other hand, remain the exception at Galaxus. «These devices tend to be sold by companies that also install them straight away,» says Daniela.

It’s striking how the owners of air conditioning systems are getting younger every year. Today, one in three air conditioning units goes to a person under the age of 35. In 2020, it was only one in five. One possible explanation: the issue of indoor temperature is no longer just a concern for homeowners, but also for tenants in a city.

It’s still unclear how hot the summer will be. Only one thing’s certain: the monoblocs will stay put – first in the bedroom, then back in the cellar.
