HVAC technician cannot diagnose why undersized filter driers cause massive temperature drops but suction pressure remains normal, indicating a gap in troubleshooting understanding or diagnostic tooling.

Existing diagnostic tools (temp probes, pressure gauges) provide conflicting data (temperature drop vs suction pressure), and there is no integrated intelligence to reconcile the discrepancy and pinpoint the root cause (undersized driers acting as restrictions under certain conditions).

Diagnostic tool that integrates temperature and pressure data to identify component sizing mismatches

App Concept

HVAC Diagnostics AI

An AI-assisted diagnostic tool that analyzes combined temperature and pressure readings in real-time, cross-references component specs, and suggests root causes for anomalous conditions like normal suction pressure with high delta-T across filter driers. It helps technicians quickly identify sizing mismatches and other hidden issues, reducing callbacks and confusion.

Key Features

Real-time data ingestion from temp probes and pressure gauges
Database of component specs to detect undersized driers, valves, etc.
Diagnostic logic that reconciles conflicting signals (e.g., normal pressure but high delta-T)
Step-by-step troubleshooting guide and report generation

Target Users: HVAC technicians servicing commercial RTUs, especially those dealing with aging R22 systems

Revenue Model: $49/mo per technician subscription or $199/mo for company fleet with priority support
