Mr Cool DIY-24-HP-230B

Purchased from Amazon March 30, 2022 for $1,802.22 currently, April 10, 2023, $2,492.00 I rigged it so I can easily power it from a generator. I was concerned for an extended power outage at the height of summer.

This was fairly manageable install except the room unit that was placed on a wall that was too deep for the wall unit hoses, I had to add the full hose set as the union was in the wall when room unit placed. I installed the entire system by myself, except I finally had to call in the 'big guns' (Thanks Brandon) to place the unit after my inclined plane with block and tackle attempt failed

Here is a twitter thread of my entire MiniSplit installation. https://twitter.com/jhalbrecht/status/1247948090033623040

Questions

• Replace current Trane XE 1000 with a newer unit, or add additional mini split(s)
  • retro fit new technology compressor and ?whatever? upgrading the Trane XE 1000? or just replace the entire outside compressor and fan etc ??
  • Can we leak test the line set after cutting from the existing a/c?
  • Multi zone control with new heat pump and top unit?
    • Size? How to get it into the garage attic?
• If I decide on a mini split should the existing ducting be capped off?
  • At the attic unit? Or at each room vent?
• Can the current mini split have two small wall units added for the other two bedrooms on that hall?
• Put a Mini Split on the slab where XE 1000 is. Add a couple splits in kitchen / dining room and another in the living room.
• What's a good wrap / tape for the mini split lines? The foil and fiberglass I installed is degrading rapidly.
  • Special bonus if I could have another zone in the garage. !!!! :-)
• I think the XE 1000 is seer 10. How to get to seer 20? Can I replace the coils in the xe80 and compressor and coils in the XE 100?
• If new unit keep in mind I'm a DIY guy and want access to telemetry and control. Integration with HomeAssistant++
