Intermittent high head pressure spikes in an RTU with microchannel condenser, despite verified charge, new components, and clean coils—only occurs randomly and briefly, making diagnosis impossible with current tools.

Current diagnostic tools (gauges, temp probes) only capture steady-state conditions. The intermittent, transient spike (2 seconds) cannot be caught without continuous logging or high-speed data recording. No tool exists to correlate multiple sensor readings (pressure, temperature, airflow) at the exact moment of the spike, forcing reliance on speculation.

Real-time multi-sensor data logging tool that captures intermittent events automatically for later review

App Concept

SpikeSnap HVAC Diagnostic Logger

A portable, multi-sensor data logger that continuously records pressures, temperatures, and electrical data at high frequency. When a pressure spike occurs, it auto-triggers a detailed snapshot of all parameters 10 seconds before and after the event, enabling technicians to pinpoint root causes (e.g., flash gas, non-condensables, intermittent fan failure, or microchannel restriction). Replaces guesswork with data.

Key Features

Continuous high-speed logging (10 readings/sec) for up to 8 sensors (suction/discharge pressure, liquid/vapor line temps, fan amps, etc.)
Auto-trigger event capture: records a 30-second window around any pressure spike exceeding user-set threshold
Graphical report on smartphone app showing pre-spike and post-spike trends
Wireless sensors clamp onto lines without piercing; battery lasts 24+ hours

Target Users: HVAC service technicians and commercial refrigeration specialists who diagnose intermittent hard-start or high-pressure issues on RTUs, chillers, and refrigeration systems

Revenue Model: $499 one-time hardware kit (4 sensors + base unit) plus $19/month app subscription for cloud storage and advanced analytics
