I'm putting A/C in my truck and it is now ready for charging. I have no experience at this so am looking for feedback on the initial charging of the system. Is this a DYI task or best to have a shop do this? I know the parts stores sell small amounts to top one off if it has leaked some but haven't heard about the full initial charge. Thanks for any ideas here.
