Business Challenges

ThermFlo’s strong heritage of superior service faced a growing internal threat: Outdated field service processes were impeding technicians’ responsiveness and productivity. Delays in emergency repairs for HVAC and power systems can have dire consequences, especially for temperature-sensitive environments in data centers, hospitals, and other life safety and mission-critical applications.

Major issues included:

  • Field technicians lacked a unified technology platform to streamline their jobs. Manual workflows and cumbersome communications hampered their abilities to respond quickly to customer outages, make timely repairs, and report job time and costs accurately
  • Dispatchers had little visibility into the technicians’ locations and the status of the jobs underway, hindering their ability to prioritize new jobs
  • Without real-time, easily accessible information, ThermFlo employees previously used multiple platforms and interfaces to schedule service calls, order parts, schedule follow-ups, confirm commitments, and invoice clients

In addition, outdated technology, inefficient workflows, and hindered communications caused:

  • Inability to share accurate information across departmental lines within the system
  • Inability to produce automated, real-time metrics and reporting
  • Delayed client deliverables
  • Inability to track field technicians in real-time
  • Incomplete work order submissions
