What it does

Cold Pulse gives aircon service companies real-time visibility across their entire fleet. IoT sensors report pressure, temperature, and electrical data every 30 seconds. When something goes wrong, AI detects the fault instantly and generates a full diagnostic report — root cause, confidence scores, parts needed, and step-by-step repair instructions. Jobs are auto-created in simPRO or ServiceM8 and assigned to the closest tech. No more blind callouts, no more return visits.

Post-mortem · Why it died

Piloted in 2 stores, but I couldn't get the per-unit hardware and monitoring cost low enough for the value to stack up for service businesses. The diagnostics worked; the unit economics never closed — so I ended it rather than ship something that didn't pay for itself.
