For reference, here’s what we have: 36KBTU AIRHANDLER/HEATPUMP HI-STATIC M SERIES DUCTED SYSTEM INDOOR MOD# SVZ-KP36NA OUTDOOR MOD# SUZ-KA36NA2

It’s a slightly older model as we had height restrictions to work around. This prevented us from getting a newer or hyper heat model. IIRC ours had good efficiency into the 20F range which was plenty for us.

In comparison, the Trane dropped efficiency at 50F and needed heat strips at that temp (so pretty crap).
