Startup Idea: QR Code Diagnostic App for HVAC Industry

Startup idea to develop a mobile app for HVAC technicians that enables them to scan QR codes of units to access historical repair data, therefore improving diagnostics and saving time.

I am in the HVAC industry. I think it would be a good idea to have an app that could read QR codes for each unit that you do repairs one. For example, if you went to someones house and didn't know what previous technicians did, all you would need to do would be to scan the QR code and you could see every part that was ever replaced on that unit. This would save time and money for the diagnostic prospect for technicians.
