I'm installing a multizone ductless minisplit in my house.
Many of the items I need have already been purchased, I have not purchased:
- Line Sets
- Nitrogen Testing Tank
- 410a Refrigerant
I'm considering building my own line sets, it seems cheaper. But I cant seem to find the proper insulation for 1/4" & 3/8" lines. This look like the type of insulation I would want, but I cant find it for the sizes I need.
Would the 1/2" ID work for my 3/8" line? I think probably not. Can someone please provide me a resource where I can find the proper insulation?
In regard to the Refrigerant and Nitrogen... These seem a bit more expensive then I was hoping, think I can find someone in southern NH / northern MA that would rent something like this to a non-licensed person?
