I'm in the process of purchasing a SFR to rent out. During the contingency period, prior to (and discpvered upon) inspection, we found someone had ripped out the accessible copper, including the a/c lines. My question is this: what effect will this have on the system? If the copper pipes are replaced, will it be possible to simply recharge the refrigerant and be good to go? I realize that the system may not operate for completely different reasons, seeing as how I've been unable to test it, but before I get bids pn the job I'd like to know what I can expect. Thanks!
