Heatwaves, Policy Shifts, and the New Cooling Economy

The most significant recent catalyst arrived in late June 2026, when Europe endured record-breaking temperatures that exposed a profound infrastructure gap. According to the International Energy Agency, total ownership of air conditioning units in Europe stands at only around 20%, leaving the majority of households unequipped for extreme heat. The market response was immediate. Samsung reported double-digit sales growth across Italy, Spain, and France in the first half of the year, while LG operated its South Korean production lines at full capacity since April. 

Midea's experience was particularly striking: demand for its PortaSplit air conditioner was so intense that second-hand prices exceeded those of new units. The company reported that sales through German e-commerce channels rose approximately 37% in May year-on-year, while shipments in Spain and France jumped 108% from a year earlier. 

This European surge mirrors a broader Asian pattern observed in 2025. During China's record-breaking summer heat, sales of air conditioners surged 112% month-on-month, according to e-commerce giant JD.com. In South Korea, Samsung's domestic home AC sales grew by 50% in the first quarter of 2025 versus the prior year, while LG recorded 60% higher domestic sales over the same period—despite an estimated 98% of South Korean households already owning air conditioning. 

Simultaneously, the regulatory environment is tightening. In January 2026, China released two national policy instruments to accelerate the transition to energy-efficient, climate-friendly residential air conditioners, including a consumer subsidy of 15% of the product sale price (capped at RMB 1,500 per unit) for purchasing the highest energy-efficiency level units.

 NMSC Strategic Perspective on the Cooling Shift

NMSC's assessment indicates that the increasing frequency and intensity of heatwaves across key markets such as India, Southeast Asia, and Southern Europe is acting as a primary catalyst for RAC demand, transforming cooling from a discretionary purchase into essential infrastructure. Our analysis interprets the European 2026 episode not as an anomaly but as confirmation of a structural climate shift that compresses procurement cycles and strains supply chains. Manufacturers with localized production hubs and flexible inventory management are best positioned to capture this demand volatility, while those reliant on long, single-source supply chains face margin and fulfillment risk. For HVAC equipment distributors and residential cooling infrastructure providers, the strategic priority is building responsive, regionally diversified capacity ahead of increasingly unpredictable demand peaks.

Section Summary: Record heatwaves across Europe and Asia, combined with tightening efficiency regulations, are converting room air conditioners from seasonal goods into essential climate infrastructure, generating sharp, geographically dispersed demand spikes.

• European AC penetration of only ~20% represents a substantial white-space opportunity for residential cooling solution providers.

• Asian manufacturers (Samsung, LG, Midea, Mitsubishi Electric) are the primary beneficiaries of the 2026 European demand surge.

• China's January 2026 efficiency subsidies are accelerating the shift toward premium, low-GWP, high-efficiency units.

• Supply chain localization and inventory agility have become decisive competitive differentiators.

Industry Impact Analysis

The surge in cooling demand carries a critical second-order consequence: pressure on national power grids. During China's July 2025 heatwave, power demand topped 1.5 billion kilowatts—an all-time record and an increase of 55 million kilowatts over the previous year's maximum. In South Korea, the energy ministry warned that peak demand could reach a record 97.8 GW, with residential air conditioning accounting for 16% of annual power demand, up from 14% before the pandemic. 

The structural trajectory is even more consequential. The International Energy Agency projects that global power demand for cooling systems is set to rise by around 1,200 terawatt hours by 2035, outstripping a projected 800 TWh increase in demand from data centres. The IEA further expects 50% of households globally to own air conditioners by 2035, up from 36% in 2022. 

Over the longer horizon, the IEA's landmark "Future of Cooling" analysis warns that the global stock of air conditioners will grow to 5.6 billion by 2050, up from 1.6 billion, equivalent to 10 new units sold every second for the next three decades. Critically, the IEA notes that ACs sold in Japan and the European Union are typically 25% more efficient than those sold in the United States and China, underscoring the substantial efficiency dividend available through stronger minimum energy performance standards. 

This grid-strain dynamic creates a powerful regulatory and commercial tailwind for inverter AC suppliers and energy-efficient AC providers. As governments confront peak-load constraints, the policy gravity shifts decisively toward high-efficiency, inverter-driven systems—precisely the segment where premium manufacturers command stronger margins.

Section Summary: Soaring cooling demand is straining power grids worldwide, prompting regulatory action that strongly favors energy-efficient and inverter-based systems, with cooling set to become the single largest driver of incremental building electricity demand.

• Cooling demand is projected to add 1,200 TWh to global power needs by 2035, exceeding data centre growth.

• Global AC household penetration is expected to rise from 36% (2022) to 50% (2035).

• The 25% efficiency gap between EU/Japan and US/China units highlights a major upgrade opportunity.

• Grid constraints are accelerating mandatory minimum energy performance standards across key markets.
