CARR vs CIEN Comparison

Carrier Global, spun out of United Technologies in 2020, manufactures and services commercial and residential HVAC systems and transportation refrigeration solutions under its flagship Carrier brand, as well as Bryant, Payne, Heil, and others across various price points. In 2024, Carrier acquired Viessmann Climate Solutions to expand its footprint in Europe with heat pumps, boilers, and solar PV equipment. Proceeds from the sale of Carrier's fire and security (Honeywell) and commercial refrigeration (Haier) businesses reduced debt and focused the company on global HVAC and refrigeration solutions. Carrier generates 75% of sales from equipment and 25% from parts and services. The company derives 50% of revenue from the US, 30% from Europe, and 20% from the Asia-Pacific region.
