HVAC technician struggles to charge R-134a refrigerant efficiently into a wine cooler unit with a receiver and TXV, observing slow subcooling response and persistent sight glass turbulence despite extensive vapor charging.

Lack of specialized charging guidelines for R-134a in small commercial refrigeration with receiver/TXV systems leads to trial and error, wasting time and refrigerant.

System-specific charging guidance app that accounts for receiver/TXV configurations and refrigerant properties

App Concept

ChargeRef Pro

A mobile app for HVAC/R technicians that provides step-by-step refrigerant charging procedures tailored to the specific system type, refrigerant, and components. It calculates target subcooling/superheat in real-time based on system readings and guides the technician through optimal charging method (vapor vs. liquid, amount, expected response time).

Key Features

System-specific charging procedures (e.g., receiver/TXV, no accumulator)
Real-time target subcooling/superheat calculator based on refrigerant type
Expected charge response time estimates for different refrigerants
Refrigerant type comparison guides (e.g., R-134a vs R-22 charging behavior)

Target Users: HVAC/R field technicians in commercial refrigeration and small appliance repair, working for service companies with 1-50 technicians.

Revenue Model: $14.99/mo per technician subscription or $99/yr per user
