line sets through wall, how are you doing it?

[misterfixit]

I'm getting really close to completing the shop build, I'll do a thread once done. I'm about to order an A/C unit, looks like it'g gonna be a 2T heat pump system. The shop has metal siding, "MaxRib" is what it is called, very similar to R-panel with different profile. I will have 1" of closed cell foam inside. My question is what are folks doing to run the line sets through the wall?

Look on YouTube. Most people just use a short 2 1/2" or 3" PVC pipe through the wall. Some units come with one. You also get some white goop to fill in the space inside.

The Mr. Cool DIY mini-splits include a conduit with a flange on one end which goes on exterior of siding. The elbow in line set cover kits cover the flange nicely.

Thanks. I might not have been clear. I"m doing a regular home split system not a mini split.

Split is split. The wall penetration works the same way.

mini splits have a pair of linesets, a electrical conduit/tray cable, and a drain. A conventional split only has the linesets.

I would figure out the smallest hole that will give you some wiggle room and protect the line set from the metal and any rubbing. You will want each line insulated and then once you figure out where you are going to run it there are a few options for the penetration to protect it from the elements.

Have you thought about running it inside the wall? Will you have a long run?

What? No! You still need an electrical cable between the split units. It might only be low voltage (thermostat wire), but it still needs to follow the lineset. And a mini-split drain also does not have to follow the lineset.

How does any of this change how you treat the wall perforation?

Not sure it will work with your metal siding tho.

It changes the size of the opening, amount of material going through this opening and the fact that the connections at this point do NOT need to Be accessed for maintenance/replacement, unlike a mini split.

Minis have flares right at the wall penetration that you need to be able to access. Very different than what he is talking about.

My HVAC contractor, 3 years ago, ran the line set through the wall and built an insulated steel cover over it.

When painted to match the house it came out very nice.

Not necessarily, and those flares can be accessed through the front via the unit.

The only time you can access a flare thru the front is if you installed the wall penetration on the opposite side of the mini. Very few do it this way because of all sorts of issues.

Do you have a minisplit?

Several. Some with the tails passing through the wall, and some with them tucked inside. I'm still lost on how this matters to the OP.

Im lost also. At least we agree there. Lol.

If you actually have minis then you obviously know they and their accessories are different than a traditional split setup and its linesets and accessories.

I have pointed out some of these differences.

But its obvious you know better.

That looks very promising. My AC guy said basically put a PVC pipe through the wall to protect the lines from the edge of the metal siding. I'm sure that would work, but i'm looking for something a little more......nice looking.
