Heat pumps are awesome, with the exception that they seem extremely prone to poor installation. My brother had 16 callbacks on his 20k heat pump install. Every time, the system had to be recharged with a complete load of the refrigerant (which is like 2000x GWP of CO2). Basically the installers didn’t bother with a torque wrench and just hand tightened all the connectors. The broke every single one, and the install company would only replace one at a time.. then it would leak.. then they replaced another etc.
