DIY: A/C Insulation

[Henry G.]

Ok, with limited knowledge of the complexities of A/C system but with a brain and sense of touch this is easy: The big line (marked "L" on the fill/drain valve cap) is ICE COLD with the A/C on, the little line (marked "H" on the fill/drain valve) is hot. That tells me simply that it is THE BIG LINE that needs to be insulated as long as we agree the goal is to get COLD AIR from the A/C!
Try and argue that......
BTW I noticed a small but definite improvement from the wrapping I did yesterday so I will continue to do some more wrapping today....

If the goal is to get colder air, you want to insulate both if possible. From the pictures posted, it looks like you can insulate the high pressure line where the exaust manifold is (that would be an important place to insulate since it's so close to a heat source).

The high pressure line should not be hot (with the exception being the line from the compressor to the condenser) or that means your condenser is not cooling the refrigerant.
