Local 99 members operate and maintain boilers, chillers, generators and automated or computerized building systems. Our job responsibilities include monitoring, repairing, maintaining and inspecting plant equipment, alarms, meters and other instruments to ensure maximum efficiency.

Our members are skilled professionals trained to work with owners, property managers and building occupants to maintain a safe and comfortable working environment – and are often the only employees on site with the training to operate critical building systems.

At Local 99, we promote our members interests through bargaining, organizing and legislative advocacy. We exist to negotiate fair working conditions, excellent wages and benefits through collective action.
