The bath intercom always cracks me up. I’m sure it makes sense in bigger, maybe multi-level houses; but I can’t imagine myself ever using it in my 2LDK.
I see the Mitsubishi one uses CO2 as the refrigerant. And the warranty lasts for ten years. And the model for cold regions recommends putting the outdoor unit in an elevated covered stand. I assume to keep the snow and wet away. I will look at the other models later. Thanks again.
