Intermittent, unpredictable high head pressure spikes in an HVAC RTU that trip the safety switch, making diagnosis extremely difficult.

Existing tools can only capture static or momentary measurements; they cannot correlate multiple sensor readings over time to identify intermittent failure patterns.

Workarounds Described

Watch gauges manually for minutes to catch spike
Use clamp meter and temperature probes to check at specific points
Reset and wait for random recurrence

Implied Software Gaps

Continuous multi-point data logging that captures transient events automatically
Correlation engine to link pressure spike with other parameters like TXV behavior
Remote monitoring and alerting so technician doesn't have to be present

App Concept

ChillTrace Intermittent Analyzer

A portable data logging and analytics device that continuously monitors refrigerant pressures, temperatures, and electrical inputs on RTUs. It automatically detects abnormal transition events like rapid pressure spikes, correlates them with other sensor data, and sends real-time alerts to a mobile app, enabling technicians to diagnose intermittent faults without manual observation.

Key Features

Multi-sensor wireless data logging (high-side pressure, liquid line temp, compressor amps, ambient temp)
Real-time anomaly detection and push alerts when parameters exceed thresholds
Time-synced event replay with zoom on pre-spike and post-trip data
Auto-generated diagnostic report with graphs and suspected root causes
Integration with existing manifold gauges (Bluetooth-enabled)

Target Users: HVAC service technicians and commercial refrigeration specialists at medium-to-large service companies who frequently encounter intermittent faults in rooftop units.

Revenue Model: $349 per device (hardware) + $19/mo SaaS subscription for cloud storage, analytics, and report sharing
