Data Center HVAC Market Size & Share 2026-2035

Data Center HVAC Market Size

The data center HVAC market was valued at USD 13.7 billion in 2025 and is projected to grow from USD 15.6 billion in 2026 to USD 36 billion by 2035, at a CAGR of 9.8%. The market's expansion is being shaped less by conventional facility cooling replacement cycles than by the thermal redesign required for AI-oriented compute. Data centers consumed approximately 415 TWh of electricity in 2024, and consumption rose to an estimated 485 TWh in 2025 following a 17% increase,. Cooling is therefore an operating constraint rather than a peripheral utility expense; the Congressional Research Service estimates that cooling can account for roughly 38%-40% of data center energy consumption. ^{[1]International Energy Agency, Energy and AI: Energy Demand from AI, iea.org}

The divergence between traditional and accelerated-compute thermal loads is central to equipment selection. Conventional data center racks averaged 8.4 kW in Uptime Institute's 2024 survey, while NVIDIA's DGX H100 reference designs support rack configurations in the 10-40+ kW range,. NVIDIA's GB200 NVL72 platform raises the design point further, with approximately 120 kW per rack and a liquid-cooling architecture intended to manage that density. This transition increases demand not only for liquid cooling hardware, but also for chillers, cooling distribution units, controls, heat-rejection equipment, and specialist installation and maintenance services. ^{[2]Uptime Institute, Global Data Center Survey 2024, datacenter.uptimeinstitute.com}

HVAC design is also increasingly affected by energy-performance and refrigerant requirements. ASHRAE TC 9.9 identifies an 18-27°C recommended temperature range for data-processing environments. At the same time, refrigerant strategy is shifting as the Kigali Amendment drives an 85% HFC reduction for developed countries by 2036. R-134a has a global warming potential of 1,430, compared with a value of 1 for HFO-1234yf and HFO-1234ze. Cooling suppliers that can combine lower-GWP refrigerants, water-aware heat rejection, and digital controls are better positioned to address the overlapping energy, compliance, and uptime requirements of large facilities.

Energy performance will determine which cooling architectures scale across regions. The average industry PUE was 1.56 in 2024, only modestly improved from 1.59 in 2020, indicating that gains from IT efficiency can be offset by infrastructure constraints as density rises,. Suppliers with equipment portfolios spanning heat rejection, fluid management, controls, and service capabilities can capture more value than providers selling isolated cooling units, because customers must balance availability, energy use, refrigerant exposure, and the operational complexity of mixed cooling environments.

Key Drivers

AI infrastructure is increasing both the amount and the technical specificity of cooling investment. More than 1,136 hyperscale data centers were operational globally at the end of 2024, and their aggregate capacity has been doubling approximately every four years,. Five major technology companies spent more than USD 400 billion on data center infrastructure in 2025, reflecting the scale of investment required to support AI and cloud capacity. For HVAC suppliers, this spending environment favors equipment that can be deployed in repeatable modules, qualified for accelerated-compute platforms, and supported across multiple construction phases.

Liquid cooling is expanding because water can absorb approximately 3,000 times more heat per unit volume than air, enabling rack-level heat removal beyond 100 kW where appropriate system architecture is used. The implication is not a universal replacement of air cooling. Direct-to-chip, rear-door heat exchanger, and immersion systems require fluid distribution, leak-management practices, service expertise, and integration with facility water loops. The commercial opportunity consequently extends from cooling hardware to design engineering, commissioning, controls, monitoring, and lifecycle support.

Energy management provides a second demand driver. Air-side economizers and other free-cooling strategies can materially reduce compressor use in suitable climates; an AIRSYS deployment in Helena, Montana, reported a 60% reduction in HVAC energy use. The benefit remains climate-dependent, with cool temperate regions capable of several thousand annual hours of free-cooling operation while hot climates require more limited seasonal use. This variation gives climate-specific engineering and hybrid architectures a stronger role than a standardized global equipment specification.

Regulation is also moving HVAC performance from an internal operating concern toward a reported compliance metric. The EU Energy Efficiency Directive requires data centers with installed IT power demand of at least 500 kW to report energy-performance information, and Delegated Regulation (EU) 2024/1364 establishes an EU-wide sustainability rating scheme,. In the U.S., Energy Star provides data center energy-performance scoring on a 1-100 scale. These frameworks increase demand for controls, metering, and integrated thermal systems that can produce defensible operating data rather than only nominal efficiency claims.

Key Restraints

High-density cooling deployments face integration and execution risk. A facility can procure a high-capacity cooling distribution unit or direct-to-chip system, yet still experience constraints in water-loop design, heat rejection, redundancy configuration, monitoring, or field-service capability. Uptime Institute's 2025 survey indicates that cooling failures are implicated in approximately 13%-19% of impactful data center outages. The cost of a design or commissioning error therefore extends beyond equipment replacement to availability risk, making operators cautious about adopting unproven architectures at scale.

Water availability creates a material constraint for evaporative and water-intensive cooling designs. Although evaporative approaches can lower electricity use in favorable conditions, they may require significant water volumes and become commercially difficult where water stress, pricing, permitting, or public scrutiny is high. This tension favors hybrid systems, closed-loop designs, and equipment capable of operating across a wider range of ambient conditions, but those options can increase capital cost and control complexity.

The supply chain is also becoming more specialized. AI-oriented cooling depends on qualified heat exchangers, pumps, valves, manifolds, refrigerants, controls, and technicians familiar with liquid-loop commissioning. Equipment suppliers must align production capacity with customer build schedules while maintaining service coverage after handover. Market growth can therefore be constrained by deployment readiness, not simply by demand for thermal equipment.

Energy and water constraints will create differentiated regional demand rather than a single global technology pathway. Cool-climate sites can use economization to reduce compressor operation, whereas hot or water-constrained regions may prioritize mechanical, hybrid, or liquid-loop designs with different capital and operating profiles. Regulatory reporting in Europe further shifts buying criteria toward measured facility performance. As a result, suppliers will need to demonstrate operating outcomes under local climate, water, and compliance conditions rather than relying on generic cooling-capacity specifications.

By Offering

Solutions generated USD 10.49 billion, or 76.4% of market revenue, in 2025 and are projected to reach USD 25.47 billion by 2035 at an 8.9% CAGR. This segment includes physical cooling infrastructure, containment, monitoring, automation, liquid-cooling integration, and energy-optimization equipment. Its scale reflects the capital-intensive nature of new data center construction and retrofit projects, particularly where AI loads require upgrades to multiple layers of the thermal system.

Services represented USD 3.24 billion in 2025 and are projected to increase at a 12.1% CAGR to USD 10.49 billion by 2035. The faster growth rate is consistent with the operational burden of commissioning and maintaining mixed air-and-liquid cooling environments. Service providers that can support design, deployment, water-loop management, predictive maintenance, and performance optimization are positioned to benefit as facility operators seek to reduce the risk of cooling-related outages.

By Cooling Technology

Air-based cooling remained the largest technology category in 2025, at USD 6.82 billion and 49.7% of market revenue. It is projected to reach USD 16.30 billion by 2035. Its installed-base relevance remains substantial because conventional enterprise environments, lower-density rooms, and supporting infrastructure continue to require air handlers, computer room air conditioning systems, containment, and economization.

Liquid cooling accounted for USD 5.49 billion, or 40.0%, in 2025 and is forecast to expand at an 11.2% CAGR to USD 16.42 billion by 2035. The segment's growth reflects the need to remove concentrated heat from accelerated-computing hardware without expanding air-movement and fan energy disproportionately. Evaporative cooling, valued at USD 883 million in 2025, retains a role where climate and water availability are favorable, while hybrid cooling is projected to grow at a 10.7% CAGR as operators seek flexible operation across changing ambient conditions and IT-load profiles.

By Equipment Level

Chillers represented USD 3.65 billion in 2025 and are projected to reach USD 10.22 billion by 2035, supported by demand for centralized heat rejection and higher-capacity facilities. Air handling units generated USD 3.11 billion in 2025, while air conditioning systems represented USD 2.39 billion. These categories remain integral to facility-scale airflow and environmental control, even where liquid cooling handles the highest-density racks.

Liquid cooling systems are expected to grow at the fastest equipment-level CAGR of 12.9%, rising from USD 1.81 billion in 2025 to USD 6.33 billion by 2035. Control systems, projected to expand at a 9.9% CAGR, gain importance as operators manage cooling sequences, free-cooling availability, fault detection, and interoperability between IT and facility systems. Cooling towers, economizers, and other equipment retain distinct roles based on climate, water availability, site topology, and redundancy requirements.

By Cooling Technique

Room-based cooling accounted for USD 8.75 billion, or 63.8%, of 2025 revenue and is forecast to reach USD 21.13 billion by 2035. It remains the dominant approach because it serves broad installed bases and supports lower-to-moderate-density environments. Its lower 8.9% CAGR relative to localized techniques reflects the limits of moving increasing volumes of air across large rooms as rack densities rise.

Row-based cooling is projected to grow from USD 3.06 billion in 2025 to USD 8.43 billion by 2035, while rack-based cooling is expected to expand at a 12.4% CAGR from USD 1.91 billion to USD 6.39 billion. Localizing cooling shortens the air path or places heat removal closer to the source, which becomes more valuable as AI workloads concentrate heat within fewer racks. The shift changes data center design practices, including floor layouts, piping strategy, monitoring, and maintenance access.

By Data Center Type

Hyperscale data centers generated USD 5.26 billion in 2025, representing 38.3% of the market, but are projected to grow at a comparatively lower 8.2% CAGR as their large installed base matures. Enterprise facilities, valued at USD 3.95 billion, are projected to grow at 10.1% as organizations modernize infrastructure for hybrid IT environments and higher-density workloads.

Colocation data centers accounted for USD 2.90 billion in 2025. Their cooling investments are shaped by the need to accommodate customers with different density, redundancy, and sustainability requirements within a shared facility. Edge facilities, while the smallest category at USD 1.62 billion, are projected to grow at a 13.8% CAGR. Their distributed footprint favors compact, modular, remotely monitored thermal systems that can operate reliably where onsite technical staffing is limited.

By End Use

IT and telecommunications led end-use demand with USD 3.90 billion in 2025, followed by BFSI at USD 2.93 billion. Financial-services facilities require resilient infrastructure and controlled operating conditions for transaction-intensive systems, supporting an 11.3% projected CAGR. Government and defense demand is shaped by availability, security, and mission-critical continuity requirements.

Healthcare and retail and e-commerce are projected to record the highest growth rates, at 14.8% and 15.6%, respectively. Healthcare's expansion reflects rising digital clinical systems and data-intensive workloads, while retail and e-commerce demand is linked to digital transactions, fulfillment systems, and customer-facing applications. Manufacturing, energy and utilities, research institutions, and other end users will continue to require cooling designs tailored to facility density, site conditions, and uptime requirements rather than standardized enterprise configurations.

The market will remain hybrid for much of the forecast period. Room-based and air-based systems retain the largest revenue pools because existing facilities and mixed-density environments still need them, while liquid systems scale around AI racks and other high-heat loads. Suppliers that support this transition without forcing customers into a single cooling architecture will have an advantage in retrofit projects, colocation facilities, and distributed edge deployments.

Water use, energy cost, and infrastructure availability materially influence technology selection, limiting direct replication of cooling designs optimized for temperate European or North American sites.

Europe and Asia Pacific will reward different forms of thermal specialization. European operators face a stronger reporting and sustainability agenda, which increases the value of metered efficiency, economization, and refrigerant transition strategies. Asia Pacific's higher growth rate is driven by a broader set of countries and climates, requiring suppliers to adapt equipment and controls to humid, hot, dense, and water-constrained operating conditions. Regional success will therefore depend on localized engineering and service capability, not merely global product availability.
