The technicians primary focus will be responsibility for comprehensive mechanical HVAC Service with a focus on Boiler/Chiller/Pump maintenance, diagnosis and repair, and to a lesser extent General Commercial HVAC Maintenance and Service across multiple commercial and industrial facilities.

Technicians must communicate effectively with building engineers, facility managers, and dispatch, maintaining precise electronic work orders and service documentation while participating in an equitable on-call emergency service rotation.
