Demand for air conditioners has risen by 340%

Against a backdrop of abnormal heat and daytime temperatures reaching +36, Luxembourg has seen an unprecedented rise in the number of enquiries regarding the installation of air-conditioning systems. According to the specialist portal Renov.lu, the number of requests for air-conditioning installations has risen by 340 per cent compared with the heatwaves of 2025. At the same time, analysts have noted a new trend: even owners of new or recently renovated homes with high levels of thermal insulation are now seeking to have cooling systems installed. In the construction sector, the term ‘summer discomfort’ (mauvais confort l’été) is increasingly being used to describe the inability of modern buildings to maintain an acceptable temperature during tropical nights and prolonged heatwaves.

A spokesperson for the installation company FH Energie confirms that customers are requesting urgent installation of the equipment. The choice of configuration depends on individual preferences: customers choose to cool either their entire homes or individual rooms, such as bedrooms only. On average, the company installs between two and three air-conditioning systems a week, with the highest demand being in the southern regions of the country.

At the same time, the large-scale retrofitting of the housing stock is hampered by regulatory constraints. Experts from the Renov.lu platform point out that current government subsidy schemes for energy-efficient refurbishment do not take the new climate reality into account. Industry representatives consider it illogical to refuse to grant relevant incentives for the installation of reversible air-conditioning units. These units not only provide cooling but also function as energy-efficient heat pumps during the winter, resulting in significant energy savings compared with traditional heating systems.

According to experts’ forecasts, the problem of buildings overheating is set to worsen in the coming years, and the presence of an air-conditioning system could become a key factor in pricing, which will put further pressure on Luxembourg’s already overstretched property market.
