super useful, asks me three questions and just tells me not to replace compressor, no other diagnostics I guess so what's the point.

Good tool for jr techs.

Luk. D. Feb 23, 2016     

I will give 2 stars just because it looked helpful at first, my 7 year old could tell me more than this app.

This app isn't even worth the time it took to write it. If you are going to write an app, please make it beneficial.

WON'T OPEN... JUST KEEPS FORCING CLOSED. I REALLY WANTED TO USE THIS APP TOO.

Dav. D. May 30, 2013     

Good for rookies. To basic. But worth the try. Not impressed

Doesn't address internal overloads in the compressor or refrigerant issues

A. G. u. Aug 22, 2012     

Of you are less than a few weeks on the job with no training it might be helpful. Does not address ref system diagnostics at all, only compressor issues, which are either it starts or it wont. After saying thencompressor wont start it asks for amp draw.... It does explain flashes on compressor modules made by copeland, but that is already printed on them. Again, possibly useful for newbies.

Only corrective action is to replace compressor or protector. Expected more with the name Emerson on it

Are you working on making this compatible with the EVO 3D? Thanks .
