This is a super NEWB question but – I have just bought a home with a "heat pump" and it is running all day and night (in the dead of winter), some of my neighbors have their "exterior boxes/units" covered and closed – maybe theirs are only AC units?
Anyways – my heat pump (Rheem RPLB-030JAZ) has a huge fan (on top) so snow is getting inside and runs 24/7/365 … is this normal? Should it be closed up or covered? Am I forgetting some kind of setting or something that I am not aware of?
Thanks,

Air Conditioners and Heat Pumps and are just refrigeration systems. The following are the differences:
Air Conditioners
Dedicated cooling only systems are often referred to as Air Conditioners and have a single usage cycle that dehumidifies and cools the interior air in the living space. These are turned off in winter time for the obvious reason that you no longer need cool air inside and so often are winter-proofed to also prevent air leakage and precipitation intrusion.
Heat Pumps
Dual purpose heating/cooling systems are referred to as Heat Pumps and have a reversible cycle. They can be used to both Air Condition and Heat the living space by switching the direction of refrigerant flow.
In the summer time, they cool the interior by heating the outside atmosphere. In winter time, they heat the interior by cooling the outside atmosphere. Hence the name Heat Pump.
They run year around and therefore must have free airflow through them year around (not be winter-proofed with air-tight coverings). Having some sort of roof with clearance to allow free airflow and to keep the snow out would be a really good idea.
