Air conditioning rented by the hour: In Paris, cooling becomes a rental service

Paris – 16 July 2026: When heat builds up in apartments, even a simple white appliance with an exhaust hose becomes a sought-after summer guest. Businesses renting out portable air conditioners report unusually high demand in the Paris region. According to one provider, up to 500 units are currently delivered every day. Short-term rental services are replacing often futile trips to sold-out DIY stores.

The model follows a very contemporary logic: Anyone who only needs cooling for a few particularly hot days does not want to spend several hundred euros, nor store a bulky appliance for 11 months of the year. Delivery, installation and subsequent collection turn rented air conditioning into a service for apartments, offices and small shops. Especially in densely built-up neighborhoods, this resembles an improvised response to a summer that will not wait.

However, whether this is a good economic choice for customers depends not only on the daily rental price. There are also delivery costs, the rental period and, above all, electricity consumption. Since late May, the French energy agency ADEME has clearly warned against rushing to buy portable units: Appliances with only one exhaust hose require a window to be left open, allowing hot outdoor air to flow back inside. This reduces efficiency and increases energy demand.

A monobloc portable air conditioner is therefore a small paradox on wheels. It promises quick relief, but under unfavorable conditions has to contend with its own surroundings. ADEME estimates the average annual electricity consumption of a portable air conditioner at nearly 710 kilowatt-hours; this figure describes typical use over a year, not necessarily the cost of a one-week rental. Nevertheless, it explains why this seemingly simple solution should be chosen carefully.

For older people, those with chronic illnesses, pregnant women or families with infants, effective cooling may be more than a matter of comfort. In the face of high temperatures, Santé publique France reminds people to pay particular attention to vulnerable individuals and those living alone. In poorly insulated attic apartments and on noisy streets, where nighttime ventilation is almost impossible, a rental unit can therefore be practical help, even if only temporary.

However, the more sustainable question begins before the delivery vehicle sets off. External shutters, keeping windows closed during the hottest hours, nighttime ventilation and shading can often reduce indoor temperatures considerably. When cooling is unavoidable, ADEME recommends setting the temperature to at least 26 degrees. Between the desire for immediate coolness and renovating apartments to withstand heat lies an entire summer—and a growing market.
