Mobile app that identifies refrigerant from temperature and pressure readings without needing the model sticker

App Concept

GasID Pro

A mobile app that uses a refrigerant sample, temperature, and pressure readings to identify unknown gases in HVAC systems. Simply input current temperature and pressure, and the app compares readings to known refrigerant properties to suggest the most likely gas, reducing guesswork and service delays.

Key Features

Input temperature and pressure to get refrigerant match suggestions
Database of all common HVAC refrigerants with PT curves
Scan barcode or QR code on refrigerant cylinder to confirm
Option to run a simple flow test for additional confirmation

Target Users: HVAC field technicians at residential and commercial service companies

Revenue Model: $9.99/mo per user or $99.99/yr subscription; free tier with limited lookups
