They are not supposed to but can for any number of reasons. You need to have a qualified HVAC tech look at your system and determine the cause if you are experiencing this. Its true unless its a heat pump which is normal in winter you should not see a heavy frost or ice. First lets examine a residential scenario without a heat pump. Freezing can be observed at the suction line the larger of the 2 copper pipes that connect between the furnace and condenser or some call it the vapor line and compressor at the condenser and on the evaporator (the inside coil) and metering device or (TXV) on higher end units. Lets examine the easy fixes first one cause can be a blocked air flow ie' a dirty air filter, a blocked evaporator coil, dirt, and dust. On some but not all units it could be a blocked suction filter, a crimped vapor or suction line. There is also the possibility that it has been caused by some kind of leak, a loose fitting, such as at the evaporator metering device which are often compression and flare connections. If the condenser has valves a valve stem packing some can be tightened and a leak fixed and some cannot, I do not recommend doing anything without first doing a simple leak check. Assuming that there is still enough refrigerant in the system with the unit off use a mild soap and apply to the points where there may be a connection as I described above, if bubbles occur, you most likely found your leak, if so do not turn more than and 1/ to a 1/4 tight and always use 2 wrenches one to tighten and 1 to hold back the other fitting.

A heat pump compressor will freeze if the refrigerant levels are low or the outside temperatures are too low. This will cause the pressure to drop inside the system and temperatures to plummet.
It would freeze over.
That refrigerant oil
You would freeze. The earth would be pretty well frozen over. The average surface temperature would be about -4 degrees Fahrenheit if there were no greenhouse effect.
If you add anything other than what the manufacture has no liability for defective. Meaning that if you bought a new or remanufactured compressor and it went bad it would not have a warranty.
Yes, the blower belt. If the blower belt, the belt that turns the blower wheel to produce air breaks on a DX unit the refirgerant system will continue to pump through the evaportator coil. With no air to remove the cooling it will begin to freeze on the coil. Over time the compressor will more than likely shut down on low pressure or overloads.
When an AC compressor is undercharged, it lacks sufficient refrigerant to effectively absorb heat from the indoor air. This can lead to inadequate cooling performance, increased energy consumption, and potential overheating of the compressor. Over time, the compressor may suffer damage or failure due to operating under stress, as it struggles to maintain proper pressure and temperature levels. Additionally, it can cause the system to freeze up, further hindering its efficiency.
Look for how it is attached and remove the needed fastners or components. No majic unfortunately.
Freeze it.
Freezing an air compressor is not recommended, as extreme cold can cause damage to its components, such as the motor and seals. If the compressor is exposed to freezing temperatures, condensation can also form inside, leading to rust and corrosion. It's best to store an air compressor in a climate-controlled environment to ensure its longevity and optimal performance.
Yes, rivers can freeze over during the winter months when temperatures drop low enough for the water to freeze.
When a compressor with two cylinders has only one pumping, you may experience reduced airflow, decreased pressure output, and noises or vibrations coming from the compressor. This can lead to inefficient operation and potential damage to the compressor over time.
