Implied Software Gaps

A diagnostic tool that inputs live data and outputs probable causes for abnormal superheat on fixed orifice systems

App Concept

CoolCalc Pro

A mobile diagnostic assistant for HVAC technicians. It takes live refrigerant readings, compares them to manufacturer specs and known fault patterns, and suggests likely causes for abnormal superheat or subcooling. Unlike generic calculators, it integrates system type (fixed orifice vs TXV), line set length, and ambient conditions to provide actionable next steps.

Key Features

Input live pressures and temperatures
Auto-calculate superheat, subcooling, and target ranges
Fault library with common causes for abnormal readings
Step-by-step troubleshooting workflow

Target Users: HVAC service technicians and contractors in residential and light commercial field service, especially those with 1-10 trucks

Revenue Model: $19.99/mo per technician subscription or $199/yr with annual plan
