This is in Arizona. The other day I was in my attic to lay some cat5 and noticed the ac lines in the attic running from the outside unit to the indoor part do not have any insulation on it. The line outside form the outside unit to the wall of the house do have insulation around it. The attic gets quite toasty and I'd think it would be a good idea to insulate them ? They are very easy to access. What do you think ?
Also, the lines are hanging from one end to the other for quite a bit of distance and not supported. While I Was up there one of the units kicked in and I noticed the line moving a little bit when the unit started.(then stopped moving, so only moved caused by the start) Probably not good either ? What do I use to hang it more secure ? The roof is a wood frame roof with tile on top. Well, Hope you hvac guru's can give me some advice,
