Johnson Controls International Plc

A global provider of commercial-building systems, Johnson Controls designs, makes, installs and services heating, cooling, fire-safety, security and refrigeration equipment sold under well-known brands like YORK, Metasys, Simplex and Grinnell. It traces its roots to 1885, when professor Warren Johnson invented the first electric room thermostat after tiring of janitors constantly interrupting his class to adjust the furnace. The modern company took shape through a 2016 merger with Tyco, and its OpenBlue software platform uses AI to run smart buildings.
