Detailed Narrative
Data Center Expansion and Innovation
Carrier's data center business reached approximately $1 billion in 2025, with Q4 orders surging over 4x. The company has expanded its portfolio to address all major data center chiller applications, increasing its share of water-cooled chillers 4x since spin-off. New maglev bearing air-cooled chillers and planned higher-capacity CDUs up to 5 megawatts in 2026 are key differentiators, alongside investments in engineering labs and manufacturing capacity.
Aftermarket Growth and Digitalization
The aftermarket segment demonstrated double-digit growth for the fifth consecutive year, driven by a successful playbook. Connected chillers increased from 17,000 to over 70,000 in three years, with a CSA attachment rate near 60%. Modifications and upgrades, which grew 20% last year, are identified as the highest growth potential area for the next five years.
Home Energy Management Systems (HEMS)
Carrier is making significant strides in HEMS, particularly with its integrated heat pump battery solution. Field trials have demonstrated up to 4 hours of battery-powered heat pump operation during peak hours, with a market launch planned for later in 2026. In Europe, the System Profi installer program, offering complete home energy solutions, saw double-digit sales growth, with plans to double qualified installers in 2026.
Container Solutions and IoT
The CST business, particularly its container segment, is leveraging end-to-end solutions. The Lynx platform now has over 220,000 paid subscriptions, including 110,000 on containers for major shipping lines. Recent investment in Net Feasa enhances wireless IoT connectivity, enabling AI-driven reefer health monitoring and predictive maintenance, which is expected to smooth container cycles and provide recurring revenues.
Residential Market Dynamics and Inventory
The short-cycle residential market softened significantly in 2025, with industry units estimated at 7.5 million, absorbing 45% of the cumulative overage from 2020-2024. Carrier reduced field inventories for residential by roughly 30% year-over-year by Q4 2025, reaching 2018 levels. The company anticipates absorbing the remaining overage in 2026, with industry units projected down 10-15% for the year.
Cost Actions and Productivity
Despite market challenges🌐, Carrier implemented aggressive cost and pricing actions, achieving strong material productivity and decisive overhead cost reductions. These actions, including a reduction of 3,000 heads in 2025, are expected to deliver over $100 million in savings in 2026 and position the company for stronger incremental margins when short-cycle markets recover. The company is also embracing AI to drive further productivity.
