Johnson Controls International is a global building technology company that designs and manufactures commercial HVAC equipment, industrial refrigeration systems, security systems, and fire-detection and fire-suppression solutions, along with integrated building controls and digital platforms. The company generates revenue through both product sales (HVAC, refrigeration, controls, security, and fire equipment under brands including YORK, Metasys, Ansul, and Simplex) and recurring service revenue from maintenance, repair, retrofit, replacement, energy-management consulting, and technical support. Beyond traditional hardware, Johnson Controls offers OpenBlue, a cloud-based software platform combining building products with artificial intelligence and machine learning to enable remote diagnostics, predictive maintenance, and data-driven smart building solutions. The company serves commercial, industrial, data center, institutional and governmental customers globally through a direct sales and service network supplemented by third-party distributors, competing against major global manufacturers while benefiting from a large installed base that generates significant repeat business across maintenance, retrofit and replacement markets.
