99 yukon denali ac problem

[99yukon84]

So I just picked up a 99 yukon denali about 2 weeks ago I noticed before I bought it that the ac did not work. Well I was able to look at it today and noticed a leak for the low pressure line when the ac is one air bubbles come out where you take the cap off that fitting looks bad. I was wondering how hard is it to change the hard line? If someone could help me out please.

the system must be discharged, repair and prepped for recharge before recharging back to normal. If you are not familiar on how to do it then you most likely don't have the right tools for hvac servicing at all. leave it for a shop.

Yes that what I was thinking the shop would be my best bet on that. Thank you for let me know!!!
