CARR
Carrier Global
Summary
What they do:
Manufactures precision cooling systems — chillers, cooling towers, and air handling units — that form the thermal backbone of hyperscale data centers, sitting upstream as the equipment supplier to every major data center operator and MEP contractor.
Why they matter:
As AI rack power density escalates from 10 kW to 70 kW per cabinet, cooling becomes the constraint that limits compute density — a single hyperscale AI facility spends $50M-$150M on cooling infrastructure, and Carrier's AquaEdge and AquaForce chiller lines are the industry-standard specification.
Recent performance:
Last quarter EPS missed consensus by -10%. Next earnings April 30, 2026; EPS consensus $0.52.
Our Verdict
Cooling is the non-negotiable constraint on AI data center density — Carrier has the manufacturing scale and specification lock-in, but the stock at 37x P/E already prices in significant margin expansion and the last quarter's miss raises execution questions.

Stand outside a hyperscale data center. The building itself is unremarkable — a massive warehouse-like structure. But walk around to the mechanical yard and you see Carrier's footprint. Massive chiller units, each the size of a delivery truck, sit in rows. A hyperscale facility might have 4-8 of them running in parallel, humming 24/7, pulling tens of megawatts of heat out of the building and rejecting it through cooling towers into the atmosphere.
Inside, thousands of server racks generate 50-100 megawatts of heat continuously — equivalent to the waste heat from 40,000 homes running simultaneously. That heat must go somewhere, or the equipment fails in seconds. Carrier's chillers are the kidney dialysis machine of the data center — running constantly, mission-critical, and irreplaceable without a complete facility shutdown.
Carrier Global is not a pure-play cooling company. It is a diversified HVAC and mechanical systems business with three major revenue streams: cooling systems (~25% of revenue), HVAC systems (~40%), and commercial refrigeration (~35%). Total revenue is approximately $22B annually with a market cap of ~$52.9B. The data center cooling opportunity sits within the cooling segment but is growing faster than the rest of the business — estimated 15-25% annually versus 5-8% for traditional HVAC.
The AquaEdge chiller line is the workhorse. These units achieve near-industry-leading COP (coefficient of performance) numbers — cooling efficiency measured in kilowatts-per-ton. A 1% improvement in chiller efficiency across a fleet of data centers saves millions in operational electricity annually. Carrier's engineers have spent decades optimizing thermodynamic cycles, compressor design, and heat exchanger geometry. The latest AquaEdge units command a 15-20% premium but save customers $500K-$1M+ per year in electricity costs over a 10-year facility life.
A large cooling quote for a hyperscale campus (500 MW across multiple buildings) can exceed $100M. That cost is built into the site economics and approved before construction begins. Once specified, Carrier equipment is designed into the facility blueprint — changing vendors means redesigning the mechanical systems.
Human scale reference
A hyperscale AI facility's cooling system rejects enough heat to warm a small city. The chiller room is in the basement or attached to the building exterior — invisible to anyone outside, but the thermal capacity determines how much compute density you can pack into the building envelope.

The Catch
Carrier's single biggest risk is that alternative cooling architectures displace traditional chiller demand faster than the company can innovate. Immersion cooling — submerging chipsets in dielectric fluid — reduces cooling costs by 40-50% and enables higher power density. CoolIT Systems and Iceotope are already shipping to Meta, Microsoft, and others. If immersion becomes the standard for next-generation GPU clusters (which is plausible given the thermodynamics), traditional chiller demand could flatten or decline, stranding Carrier's cooling manufacturing capacity and erasing the margin expansion thesis. Carrier has not yet announced a credible immersion cooling product, and the -10% EPS miss last quarter suggests the company may be slower to adapt than the market requires.
If They Win
If Carrier successfully maintains cooling infrastructure dominance in the AI data center era and develops a credible immersion/hybrid cooling product line, the company becomes the thermal utility of AI — collecting revenue from every building that runs a GPU. Margins expand from 20% to 26% in cooling, EBIT compounds at 12-15% annually, and the stock re-rates from 37x to 42-45x on the visibility of a 10+ year secular tailwind. More importantly, Carrier becomes strategically embedded in the thermal backbone of the global AI economy — not an easily replaced supplier, but a critical node that operators cannot remove without redesigning their facilities from scratch.
