Johnson Controls International plc

Johnson Controls International plc, headquartered in Cork, Ireland, is a global leader in smart, healthy, and sustainable buildings. The company provides products, services, systems, and solutions that enhance the safety, comfort, and intelligence of spaces for people, places, and the planet. Originally incorporated in Wisconsin in 1885 as Johnson Electric Service Company, it manufactured, installed, and serviced automatic temperature regulation systems for buildings, and was renamed Johnson Controls, Inc. in 1974. In 2005, Johnson Controls acquired York International, a global supplier of heating, ventilating, and air-conditioning ("HVAC") and refrigeration equipment and services. In 2016, Johnson Controls, Inc. combined with Tyco International plc, integrating building efficiency solutions with fire and security solutions. Tyco subsequently changed its name to "Johnson Controls International plc." On July 31, 2025, the company divested its Residential and Light Commercial ("R&LC") HVAC business to Robert Bosch GmbH ("Bosch"), which included its North America Ducted business and Johnson Controls-Hitachi Air Conditioning Holding (UK) Ltd. The company engineers, manufactures, commissions, and retrofits building products and systems, including commercial HVAC equipment, industrial refrigeration systems, controls, security systems, fire-detection systems, and fire-suppression solutions. It also offers technical services such as maintenance, management, repair, retrofit, and replacement of equipment in HVAC, industrial refrigeration, security, and fire-protection, along with energy-management consulting. The OpenBlue digital software platform integrates the company's products and services with technology to provide data-driven "smart building" services and solutions.
