24v from w to c? Inducer start up? Doesn't sound like you're a tech if you don't know sequence of operation.

I'd say it's broken!
These are the first 2 questions that need to be answered before we can be of much help. Also Do they have a new thermostat? If so make sure there is a jumper between RH and RC. One last thing for now, what is your model and serial numbers?
Haha probably low on r-22 to just top it off and see if it works....yea you need to know the sequence of operations to troubleshoot

Is this a Goodman? If the pressure switch is jumped or stuck closed they will sit there and smile at you with no code, even though it is locked out.
