Europe Heatwave Creates Growth Opportunity for Carrier, Trane, and Johnson Controls, Citi Says

Europe’s record-breaking heatwave could become a long-term growth driver for leading U.S. heating, ventilation, and air-conditioning (HVAC) companies as demand for cooling systems accelerates across the region, according to a new research note from Citi.

The investment bank said increasingly frequent and intense heatwaves are likely to encourage wider adoption of air-conditioning systems in Europe, where household penetration remains significantly lower than in other developed markets. As climate change fuels hotter summers, demand for energy-efficient cooling solutions is expected to rise, creating new opportunities for HVAC manufacturers.

Citing International Energy Agency data from 2018, Citi noted that only around 20% of European households currently have air conditioning, compared with approximately 90% in both the United States and Japan. This substantial gap suggests considerable room for future market expansion as consumers, businesses, and governments invest in cooling technologies.

Among the companies positioned to benefit, Citi highlighted Carrier Global (NYSE: CARR), Trane Technologies (NYSE: TT), and Johnson Controls (NYSE: JCI). The bank believes these HVAC leaders are well placed to capitalize on the growing demand for commercial and residential cooling systems across Europe.

Carrier was identified as the strongest potential beneficiary due to its significant regional presence. More than 20% of the company’s revenue is generated through its Climate Solutions Europe business. Carrier also holds the leading market share in Europe’s commercial HVAC segment and ranks second in residential and light-commercial HVAC systems, giving it a competitive advantage as cooling demand increases.

Citi also pointed to Carrier’s expanding European heat-pump business, where first-quarter sales increased by a low-teens percentage. Analysts added that strong German heat-pump subsidy applications, recorded even before the latest heatwave, indicate healthy underlying demand for energy-efficient heating and cooling technologies.

While Trane Technologies and Johnson Controls generate a smaller portion of their revenue from Europe, Citi said both companies offer HVAC products specifically designed for European customers. As governments strengthen climate adaptation efforts and households seek more efficient cooling systems, both manufacturers are expected to benefit from higher spending on air conditioning, heat pumps, and energy-efficient building solutions.

Citi concluded that Europe’s changing climate and historically low air-conditioning adoption could create a structural growth opportunity for the global HVAC industry, with major U.S. manufacturers well positioned to capture rising demand over the coming years.
