Sweating on a/c condenser lines

[TXNinAZ]

Hi all, I got a mini-split installed last month and it's been amazing. It pulls a lot of moisture out of the air and the condensate line is usually dripping slowly. All has been good, but I noticed there is moisture on the cooling lines that run to the indoor unit. I hope this is normal, given the weather here (been over 110 F over the last few weeks, humidity from 30-60%. Any thoughts?

Normal. If dry, likely out of referigerant.

You should be worried if you don't have condensation on those lines where they are exposed. This is a big reason why those lines are insulated.

Yes. The lineset will have an insulation tube on the lines. If you don't want the fittings sweating, you can cover them in foam tape.

It's normal, but do cover them. And as I see in the Picture that's the service valve that not covered, which is fine.who ever did the job cover them well, now how thick is the covering...and how much humidy are you having where you live.
