“Air conditioning isn’t the solution to our problems, but it’s the only solution we have given the circumstances of sub-optimally designed cities and little shade,” said Marc Evans, a 39-year old IT professional in Frankfurt who bought a portable unit last summer for €899 ($1055.)

Adapting to the new climate reality in Europe can be complicated and expensive. Around half of the European Union’s housing stock was built prior to 1980, according to Eurostat, meaning it’s not easy to retrofit for the ducts and wiring needed for an air conditioning system. And in Germany,  more than half of the population rents — a larger share than anywhere else in the bloc — so they often aren’t willing to invest on installing permanent AC or can’t do so without landlord permission.

Even homeowners can run into difficulties: Those living in shared buildings first need to clear adding permanent outdoor units with their owners’ association, but these requests are often shot down over noise or environmental concerns.

A small survey this month showed 18% of respondents said they owned an air conditioner, up from 13% in 2023, though estimates from Germany’s federal environment agency suggest the share is lower.  Two-thirds of air-conditioning users in Germany have single units known as monoblocks, such as window or freestanding machines with an exhaust hose, according to survey respondents.

The problem with the most popular portable alternatives is that they often suck huge amounts of power as they expel heat. “Tenants often have to resort to less effective devices than owners and that can have a noticeable effect on electricity costs,” said Daniel de Graaf, a researcher at the German Environment Agency.

Germans wanting a quick solution now also have the option of buying more efficient portable heat pumps. Midea Group Co., a Chinese appliance manufacturer, says demand for its mobile “PortaSplit” has been high in Germany, particularly given the rapidly growing rental market and persistently high temperatures, according to a spokesperson. The model sold out across many stores at the beginning of the summer, he added, and prices for the devices that remain in stock have fluctuated between €800 and €1,600 according to a comparison website Idealo Internet GmbH.

Toom Baumarkt GmbH, a hardware store chain, has also seen high customer interest in portable air conditioners. “While fast cooling and ease of use are top priorities for many customers, aspects such as energy efficiency and suitability for rental apartments are also becoming increasingly important,” said Daria Ezazi, a company spokesperson.
