Maybe you could try giving your EPA Refrigeration Handling Certificate number to one of them to prove you are legally doing this.
All that aside your local HVAC professionals are trying to actually make a living and have no time to play Mr. Wizard with unknown callers. Why not make a service appointment with a local professional, at least he can get a good laugh and a service call out of the experience.
