Top Stocks · DATA CENTER COOLINGUpdated May 28, 2026
Data center cooling is becoming one of the most important picks-and-shovels themes in the AI buildout. As compute clusters get denser, traditional air cooling is reaching practical limits, especially in facilities designed around higher-power GPU racks. That is pushing spending toward chillers, heat rejection systems, coolant distribution units, heat exchangers, controls, and integrated thermal platforms that can keep performance high without letting power and water use spiral.
The opportunity spans several layers of the stack. Facility-level providers supply chillers and broader thermal infrastructure, rack-level specialists address liquid cooling and distribution, and component-level players provide the connection, protection, and thermal management hardware needed inside mission-critical environments. Recent industry moves reinforce the trend: Trane announced a deal to acquire LiquidStack, Johnson Controls launched new high-density chiller platforms and a Silent-Aire CDU portfolio for AI factories, and Carrier invested in ZutaCore to advance direct-to-chip liquid cooling.
For investors, the key distinction is whether a company has named, commercialized data center cooling exposure or just broad HVAC exposure that may benefit indirectly. This list focuses on investment quality within that theme, balancing business relevance with profitability, growth, valuation, and execution. The picks are presented in countdown order, starting at No. 7 and ending with our top-ranked name at No. 1.
We screened for U.S.-listed companies with market capitalizations above $500 million and meaningful exposure to data center cooling, thermal management, or closely related infrastructure. We then ranked the group primarily on investment quality, using a mix of composite quality grades, profitability, growth, earnings execution, analyst sentiment, and how directly each business maps to the theme. Because this is a countdown, the most attractive combination of thematic relevance and overall quality appears last at No. 1.
What they do. The company provides intelligent climate and energy solutions across residential, commercial, and transportation markets. Its portfolio includes air conditioners, heating systems, heat pumps, building energy management and automation systems, aftermarket components, and repair, maintenance, rental, modernization, and upgrade services.
Why it fits. Carrier ranks lower because it is still a broad HVAC company rather than a pure data center cooling play. Even so, it belongs on the list because the theme context specifically notes that Carrier invested in ZutaCore to advance direct-to-chip liquid cooling, giving it a more concrete link to next-generation thermal architectures than a generic commercial HVAC supplier.
Numbers that matter. Carrier generated $21.87 billion in revenue and $3.14 billion in EBITDA, with a 25.2% gross margin, 6.57% operating margin, and 5.99% net margin. Revenue growth was positive but modest at 2.4% year over year, while earnings growth fell 40.7% year over year. The stock trades at 42.99 times trailing earnings and 22.57 times forward earnings, so investors are already paying for a rebound despite the weaker recent earnings trend.
Recent momentum. Execution has been mixed, with Carrier beating in 4 of its last 7 reported quarters. The last two reports missed expectations, including a 24.3% miss on April 30, 2026 and a 5.6% miss on February 5, 2026. Analyst sentiment is lukewarm: the consensus score is 4.04, with 5 buys, 8 holds, and 1 sell, alongside an average target of $76.0809.
What they do. The company designs, manufactures, installs, and services HVAC, controls, building management, refrigeration, fire, security, and digital building systems. It serves commercial, institutional, industrial, governmental, marine, and data center customers, giving it a broad installed base and recurring service exposure alongside equipment sales.
Why it fits. Johnson Controls has direct thematic relevance because its description explicitly includes data center customers, and the market backdrop highlights its launch of new high-density chiller platforms and a Silent-Aire CDU portfolio for AI factories. That gives it named, commercially relevant exposure to both facility-level cooling and liquid-cooling-adjacent infrastructure, even if the company remains diversified well beyond the theme.
Numbers that matter. Johnson Controls posted $24.43 billion in revenue and $4.32 billion in EBITDA, with a 36.6% gross margin, 14.02% operating margin, and 14.45% net margin. Growth is solid for a large-cap industrial: revenue rose 8.2% year over year and earnings increased 38.9% year over year. Valuation is not cheap at 42.88 times trailing earnings and 29.33 times forward earnings, but the profitability profile is stronger than many diversified peers.
Recent momentum. The company has executed well recently, beating estimates in 6 of the last 7 quarters. Its two most recent reports both topped expectations, including a 6.2% beat on May 6, 2026 and a 6.0% beat on February 4, 2026. Analyst sentiment leans constructive but not aggressive, with a 3.9565 consensus score, 4 buys and 10 holds, plus an average target of $150.85.
What they do. Trane designs, manufactures, sells, and services a wide range of HVAC and refrigeration solutions. Its portfolio includes chillers, exchangers, handlers, controls, commissioning, energy and water efficiency programs, thermal energy storage, and aftermarket services, and its description specifically includes data center HVAC among its served applications.
Why it fits. Trane is one of the more credible diversified names in this theme because it already lists data center HVAC in its offering set, and the market backdrop notes its planned acquisition of LiquidStack to expand end-to-end data center thermal management. That matters because hyperscale facilities increasingly want integrated solutions spanning chillers, heat rejection, controls, and liquid-cooling systems rather than isolated components.
Numbers that matter. Trane generated $21.60 billion in revenue and $4.23 billion in EBITDA, with a 35.9% gross margin, 15.52% operating margin, and 13.42% net margin. Profitability is excellent, including 36.63% return on equity and 11.34% return on assets. Revenue grew 6.0% year over year, but earnings growth dipped 2.1% year over year, which helps explain why the stock's 35.24 trailing P/E and 30.58 forward P/E still leave less room for disappointment than some faster-growing specialists.
Recent momentum. Trane has beaten estimates in 6 of the last 7 quarters, including a 4.0% beat on April 30, 2026. The one miss in that stretch was modest, at 5.0% below estimates on January 29, 2026. Analysts remain measured rather than enthusiastic, with a 3.4615 consensus score, 2 buys and 15 holds, though the average target stands at $520.2191.

What they do. nVent designs and manufactures electrical connection and protection solutions used in mission-critical applications, including data centers. Its offerings include bus systems, cable management, control buildings, enclosures, power management, switchgear systems, and notably liquid and air-cooling solutions, giving it a broader infrastructure role than a pure HVAC vendor.
Why it fits. nVent fits this list because modern AI facilities need more than chillers alone; they also need protected power and data pathways, equipment enclosures, and thermal systems that can operate in dense, mission-critical environments. The company explicitly serves data centers and offers both liquid and air-cooling solutions, which makes it a useful way to invest in the broader thermal-management buildout.
Numbers that matter. nVent produced $4.33 billion in revenue and $924.2 million in EBITDA, with a 37.0% gross margin, 16.0% operating margin, and 11.37% net margin. Revenue growth was exceptionally strong at 53.5% year over year, although earnings growth fell 59.5% year over year, so the growth story is not perfectly clean. The stock trades at 57.39 times trailing earnings and 36.90 times forward earnings, a premium that assumes the data center and electrification tailwinds remain durable.
Recent momentum. Recent execution has improved, highlighted by a 16.0% earnings beat on May 1, 2026. Over the last seven reported quarters, nVent beat in 4, matched estimates twice, and missed once materially in late 2024. Analysts are notably positive here, with a 4.5385 consensus score, 4 buys and 1 hold, plus an average target of $183.3077.
What they do.AAON engineers, manufactures, and sells air conditioning and heating equipment through its AAON Oklahoma, AAON Coil Products, and BASX segments. Its product lineup includes rooftop units, air handling units, condensing units, coils, controls, cleanroom systems, and specifically data center cooling solutions, making it more directly tied to the theme than many broader HVAC peers.
Why it fits.AAON stands out because data center cooling is not just an adjacency in its description; it is a named end market and product category. That direct exposure matters in a market where investors increasingly want companies with commercialized offerings for high-performance computing environments rather than vague AI halo effects.
Numbers that matter.AAON generated $1.62 billion in revenue and $251.1 million in EBITDA, with a 26.2% gross margin, 11.55% operating margin, and 7.31% net margin. Growth is the main attraction: revenue rose 54.3% year over year and earnings increased 37.1% year over year. The tradeoff is valuation, with the shares at 98.69 times trailing earnings and 68.03 times forward earnings, which is why a strong thematic fit does not automatically translate into the top rank.
Recent momentum. Recent results were encouraging, including a 65.5% earnings beat on May 7, 2026 after a miss in the prior quarter. Over the last seven reported quarters, AAON beat estimates 4 times, but the misses were sometimes sizable, including negative surprises of 44.1% and 43.7% in 2025. Analysts are cautious overall, with a 3.8333 consensus score, 1 buy and 3 holds, and an average target of $143.5.
