A lone field technician must troubleshoot and repair complex 3-phase chiller systems under intense observation without remote diagnostic tools or support, and intermittent faults don't show up during onsite visits.

Existing diagnostic tools don't provide remote monitoring or historical data logging to catch intermittent electrical faults like chattering contactors, forcing technicians to rely on manual observation and video recordings.

Workarounds Described

recorded everything on video to capture intermittent fault
multiple experts idly watching technician work onsite

Implied Software Gaps

Remote monitoring system that automatically captures data when intermittent electrical faults occur

App Concept

FaultSnap Remote Diagnostics

A mobile app and edge device that continuously monitors HVAC electrical systems (contactors, compressors, control boards) and logs voltage/current data. When an intermittent fault occurs, it automatically captures a diagnostic snapshot and alerts the technician, eliminating the need for onsite observation and video recording.

Key Features

Real-time monitoring of 3-phase power and contactor status
Automated fault detection and snapshot capture for intermittent issues
Remote access to historical data logs and waveforms
Integration with existing building management systems

Target Users: HVAC field technicians and service companies that maintain commercial chillers and 3-phase equipment

Revenue Model: $49/mo per technician subscription, plus $199 one-time edge device
