How was the conversion done?

I would bring it to an a/c specialist - they will tell you whats wrong, get a quote and shop parts. Or if the price is good - have them do it.

Many conversion failures I have read about here

Frequent problem with r134 retrofits is when o-rings are not changed. R12 is thicker than r134. If you keep the r12 o-rings with r134 your charge will just leave much quicker.
Have you checked the charge : is it enough ? Another possible problem is that you put TOO MUCH charge : if that occurs the symptoms will be the same as for a low charge : hot air
