It's important to insulate the vapor (large) line on the AC lineset.  This video is about installing my ACIQ split system, but it also applies to anyone who's AC insulation is deteriorated or missing.  You can buy quality line insulation at any HVAC supply house, whether you are a contractor or not most will sell it to you.

Armaflex is closed cell insulation which is higher quality.  This video shows how to install it following the manufacturer guidelines and with what materials I have on-hand.
