1. Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
2. Cleaner air - As you central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and line. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
3. Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.
Actually i really think cenralized aircon unit is more effecient than split type aircons since you just have to buy one unit and then the whole house gets their share of the aid conditioning.
