Our service personnel are responsible for performing preventative maintenance on our clients equipment in accordance with the maintenance program that they invested in.  The service personnel are also responsible for responding to our clients request for service during emergency situations.

It is GRC Mechanical Services policy to perform thorough preventative maintenance inspection and to take a proactive action to avoid equipment failure.  The service department’s efforts have yielded our clients many benefits including reduced repair and operating costs, prolonged equipment life, high level of equipment reliability, and enhanced customer satisfaction.

Since our service personnel are our “front line” of representation to the customer we want them to have proper presentation, quality training and tools, and support from the service manager and engineers.

At GRC Mechanical Services training occurs in three ways:

  1. On-the-job training takes place through preventative maintenance performed on new equipment under the supervision of the service manager or engineer.
  2. Formal classroom training occurs at manufacturer and supplier facilities throughout the year.
  3. Informal classroom training occurs in–house during the fall and winter.  After working hours we will have dinner together at our main office and watch training videos on new products & procedures, or on existing technology for new personnel.

A Typical Day
All personnel report to the central office at 8:00a.m.  From there they are given work orders for maintenance or repairs along with any materials that they will need.  The service vehicles are all newer model vans that are fully stocked with equipment and parts.

Throughout the day, personnel keep in touch via Nextel Communications.  If at any time a service technician requires parts or tools not in the truck, someone from the office will deliver them.

At the end of the day all service technicians report to our central office by 4:30 p.m. and brief the service manager on job details before departing home.

Every weekend a service technician is required to be on stand-by for emergency calls, there is a rotating schedule among all service personnel.  Service technicians on stand-by shall be paid time and a half for calls.  If there are no calls the service technician shall be paid for two hours straight time per day.
