The first question that you need to answer when deciding on the cooling system for your home is, whether you need to go for central air conditioning or room air conditioning. Well, the answer would depend on both your requirements as well as your budget.
First, you need to decide on the actual area you want to cool and next, you need to identify whether you can bear the cost of installing and maintaining that type of cooling system.
Before you decide on the type of AC unit, you need to understand how each type of air conditioning works.
Central air conditioning:
This type of system helps cool the entire house using a single condenser, ducts to bring in and take out the air, and a fan-and-coil system. The condenser is normally set up outside the house. Central cooling systems normally work in tandem with forced-air furnaces. In a case where that is not used, the fan and coils for the AC unit will be set up in the attic.

Room air conditioning:
In room air conditioning, the units can be either fitted in a window or mounted on a wall. Either way, the unit connects to a standard electrical outlet and does not require any extra wiring. As its name suggests it is meant to cool only a room. The size of the room would determine the size of the unit that you would need to purchase.
