Impact of Nvidia's New Chips on HVAC Stocks

On January 6, 2026, shares of U.S. heating, ventilation, and air conditioning (HVAC) companies experienced notable declines following comments made by Nvidia CEO Jensen Huang at the Consumer Electronics Show (CES) in Las Vegas. Huang announced that Nvidia's upcoming chips, particularly the Vera Rubin platform, could drastically reduce cooling requirements for data centers, stating that "no water chillers are necessary for data centres." This revelation led to a 7.5% drop in Johnson Controls International's stock, which fell to $112.40, and a 5.3% decrease in Trane Technologies' stock, which reached $370.40. Both companies hit multi-month lows and were among the largest percentage decliners on the S&P 500 index.

Barclays analysts, led by Julian Mitchell, emphasized the significance of Huang's comments, noting that Nvidia's central role in the AI ecosystem warrants serious consideration of the implications. They highlighted that data centers contribute a low-double-digit percentage to Johnson Controls' total sales, while Trane Technologies and Carrier Global derive approximately 10% and 5% of their sales from this sector, respectively. Consequently, the analysts identified these companies as particularly vulnerable to the anticipated changes in cooling requirements.

While some HVAC stocks suffered losses, others may stand to benefit from the shift in cooling technology. Analysts pointed out that nVent Electric, which lacks a presence in traditional space cooling and chillers, holds a strong position in data center liquid cooling. As a result, nVent's shares increased by 0.5%. Similarly, Vertiv Holdings, a maker of data center power equipment with a robust historical position in precision air cooling and liquid cooling, may also gain from these developments, despite its shares declining by 2.1%.

Despite the optimistic outlook for some companies, there are concerns regarding the feasibility of Huang's claims. Critics argue that the assertion of eliminating water chillers may be overly ambitious and could face practical challenges in implementation across various data center environments.

In response to Huang's comments, analysts and market observers have expressed a mix of caution and optimism. While some view the potential for reduced cooling requirements as a significant advancement, others remain skeptical about the immediate impact on existing HVAC companies.

There is a divergence in perspectives regarding the long-term implications of Nvidia's new chips on the HVAC market. While some analysts foresee a transformative effect, others caution against overestimating the immediate consequences for companies reliant on traditional cooling systems.
