MACS Mobile A/C Diagnostics App


MACS is proud to offer our mobile A/C diagnostics app to our members. The app was developed by MACS member and digital industry leader SHIFTMobility.

All MACS members will receive ONE MACS mobile A/C diagnostics app free of charge provided their dues are paid. Additional downloads are $60 annually.  The app is for both Apple and Android mobile devices and can be downloaded from your respective app store. Search for MACS Mobile A/C Diagnostics. After the download expect to be verified within 24 hours.

How does it work?

The MACS mobile A/C diagnostic app is a native app, meaning you have the ability to use many of the built-in features of your mobile device.


On the top of the screen, to the right of Mobile A/C Diagnostics you will see a stacked bar icon.  Press it to access settings. This is where you can change your password and add your business information.
