Probably not. The exchange coils may be.
Copper is commonly used in AC units because it is an excellent conductor of heat and electricity. This allows for efficient heat transfer and helps the AC unit operate more effectively. Additionally, copper is durable, corrosion-resistant, and easy to work with, making it a reliable choice for AC components.
no need to change the copper tube if the capacity of the unit is same.

DC
They have to be thrown at the right angle.
DC is necessary in the electrolytic process to refine copper. In other processes for extracting the metal from the ore, where heat is needed, AC is preferred because it is more easily transmitted over distances.
...and DC? yes. The voltage rating may change, though.
It is AC, alternating current. To create DC the generated power needs to go through a full wave rectifier.
There are some people out there that wonder the same question. Usual the ones that sale the ac equipment it for scrap this is not a concern of ours. We buy our tubing in lenghts.
Not much. But they have copper pipes and condensers. Very attractive to the thieves at today's prices.
For a 200 amp AC circuit, the recommended wire diameter for aluminum is typically around 2/0 AWG (0.3648 inches) and for copper it is around 4/0 AWG (0.4600 inches). Please consult with a qualified electrician or refer to the National Electrical Code for specific sizing requirements for your installation.
