I had an install of a heat pump slightly oversized for the work trailer used. Every day it was below 30-40F 0C-4C, the pre-heater would kick on. A heat strip inside the heat pump.

It would take 30min to an hour to get heat out of the heat pump. We had to get portable heaters to supplement the heat generated and while the pre-heater was running.

Then in summer it could not handle cooling so we needed an additional loud window AC.

So obviously it was undersized, not oversized, lol
