Oh god I feel for you, we just changed out *everything* and its been needed for years.

It does mean i can move both of my miners to the basement though and keep the setup much simpler than the chimera i had running last winter. It worked but it was frustrating and half finished. 

 I wonder.... If you install miners inside the ducts... can you clock them faster in summer because the AC cools them, and help heat the house with them in the winter?  😂
