Default Disrupt a/c for heater core??

I found the "Fastguy Method" in the archives. It looks pretty thourough!
I have a friend who owns an Auto repair. He brought up the labor, and it talked about recharging the a/c afterwards. He said that it appears that the a/c lines have to be interupted.
My car is an 89, do some years have to remove lines. It does not mention this in the "Fastguy Method"!
I ordered the Delco core today and plan to tear it down this next week!
Thanks!

If you are replacing any of the components in the A/C system (ie; evaporator, condensor, compressor, receiver/dryer) the lines are going to have to be removed from that component and when the system is put back together it will need to be evacuated (vacuumed down).

Heater core? No, you shouldn't need to disturb any A/C lines for that, just the 2 heater hoses.
