Many of the homes I see are done in EMT per an old local code requirement, and quite often the panel is full.
For this reason, I would consider removing and replacing the existing wire and breaker "the right track".
Situations may vary.

The panel is full and space is needed to add the new 30 Amp breaker. The dedicated circuit for the 220 outlet is was added for an air conditioner, but is in a location where no AC is needed (laundry room). Electrician # 2 is using this logic (AC outlet will not be in use so he's proposing to use it for the dryer).
I have verified that the 220 outlet is in fact 12G wire and informed both electricians. Waiting for prices to run a new dedicated 10G line back to a new 30 amp circuit.
Thanks for all your replies. I have another question: Is adding the 30 amp circuit as simple as swapping out the existing 20 Amp circuit (this is a dedicated circuit for the AC outlet)? There is no room elsewhere on the panel unless some things are rearranged. I want to make sure the bids I get consider this if there is some rearranging that need to be done at the panel?
Just replace the #12 with #10 and swap the 20 for a 30.
You can use the 20 amp space for the 30 amp breaker, but you need a new 10/3 w/grd and a NEW box because the existing one is too small for a 30 amp receptacle. In other words there is NOTHING about the 20 amp circuit which can be used for the dryer, and the "electrician", it that is what he really is, should have known that. I am also sure that the #12 wire was 12/2 and NOT 12/3 which the electrician should also have known.
