Fault Detection and Diagnosis

HVACServiceAssistantG&B Environmental now has a way to measure and diagnose your packaged roof top units performance. The HVAC Service Assistantâ„¢ is a unique hand-held fault detection and diagnostic tool for servicing air conditioning Units. The Service Assistant provides unique visibility into the performance and diverse costs associated with HVAC maintenance. It is the only tool on the market that calculates four different performance indices:

  • Evaporating temperature
  • Condensing temperature over ambient
  • Superheat
  • Subcooling

Field Diagnostics processes, protocols and reporting build feedback into every step of the maintenance and repair process. Using the HVAC Service Assistantâ„¢ provides objective information to technicians on the rooftop, to their service managers monitoring the work that is being performed, and to end users and facility owners who want to know the true status of their equipment. With the data transmitted from the databases housed on Field Diagnostics servers and accessed via the Service Assistant Online web service, reports are generated to address:

  • How efficiently units are running
  • How to prioritize retro-commissioning or tune-up measures
  • How much lower the electric usage will be when the tune-up is completed

The result is that managers can measure the impact of their service and maintenance expenditures and feel comfortable they are making good decisions.
