Why do room air conditioners ice up easier that central air conditioning system?

Generally the thermostat setting is too low with the fan speed set at minimum or low, this results in the ac unit operating continuously and not cycling .
The room ac unit may be undersized resulting in the ac cooling mode operating continuously so that the compressor does not cycle.
Another reason could be that the refrigerant charge is insufficient. Finally, as the ac is visual, therefore icing up will be noticed.
A central ac unit is usually out of sight externally to the dwelling or mounted on the roof.

When is Central Air Conditioning the Best Answer?
Central air conditioning may not always be the most practical choice for every home or office. There are some cases, however, when using a central air conditioner is vital to the health of everyone who lives or works in a home or building. The Length of the Hottest Season The biggest consideration for whether or not central air conditioning is the best answer is how long the hot season is in your location. Some areas have a very short hot season that only lasts a couple of weeks. The expense of installing and maintaining central air conditioning may not be worth it if you only use the system once or twice a year. If your hot season lasts for months, though, the use of central air conditioning may feel like more of a necessity than a convenience. The Size of the Building Building size also makes a difference when you consider central air conditioning. If your home or office is relatively small, you may be able to make due with a window air conditioner or a portable air conditioner. If there are more than four or five rooms, central air conditioning may be the best answer. With a central air system you can be sure that every room is cooled equally. When you use other air conditioning systems, their cooling effects can only be felt in the room that they are housed in. If you have a building with a large central room, portable or window air conditioners may not have the power to fill the space the way that central air conditioning could. The Health of the Occupants Central air conditioning is the best type to use if you are trying to keep older or younger people comfortable through the heat of the summer. Any building that houses senior citizens or young children should consider the benefits of central air conditioning to keep their inhabitants safe from the damaging effects of heat. People who are old, young, or in ill health are particularly susceptible to heat. Portable and window air conditioners may work for the short term, but central air conditioning will provide a more even distribution of the cool air.
Benefits of a Ductless Air Conditioner?
Ductless air conditioners provide several advantages over other types of air conditioning units. Because they don�t require ductwork, they are less expensive and easier to install. Unlike window units, they don�t obscure your view, require that a technician cut holes in your walls or enable unsecured access into your home or office. The compressor unit for a ductless system is placed outside the building. This eliminates the noise that you would normally have with a widow unit. The outdoor unit for a ductless system is also smaller and quieter than a central air conditioning system.
What exactly is central air conditioning I know I have AC, but what makes it central?
Central air conditioning is an air conditioning system with a central unit that distributes air to the rest of the house through vents.

That is what is referred to as Central Air conditioning, because there is just one centralized unit cooling the entire place, as opposed to many autonomous units cooling each room.
