HVAC technicians juggle a PT chart booklet, 2-3 separate reference apps, and handwritten reports on every service call. RefriPro puts all of it in one offline Android app. - PT chart calculator for 50+ refrigerants - Superheat/subcooling calculator with 6-state diagnosis — not just a number, but what it means - 754 error codes across 8 major brands (Carrier, Daikin, Trane, Lennox, Mitsubishi, LG, Fujitsu, Samsung) Everything runs locally. No internet required. Free on Google Play.

Real-time monitoring that helps you ship with confidence

I started RefriPro because I kept hearing the same complaint from HVAC techs: "I need three apps and a paper chart just to do basic diagnostics." The typical workflow looks like this — open one app for the PT chart, another for error codes, pull out a booklet for the obscure brand, then write the report by hand back in the truck. Half of this happens on a rooftop with no cell signal. So I built a single app that handles PT charts, superheat/subcooling diagnosis, error code lookup, and PDF reports. Everything runs offline because the places where techs need these tools the most are the same places with zero reception. Right now it's Android only and covers 50+ refrigerants and 754 error codes from 8 brands. The error code database was the most tedious part — manually compiled from service manuals. I'd love to hear from anyone in the trades: what's missing? What would make your service calls easier? I'm building this based on real field feedback, not guesses.
