Central Air Conditioners

Types of Central Air Conditioners
A central air conditioner is either a split-system unit or a packaged unit.

In a split-system central air conditioner, an outdoor metal cabinet contains the condenser and compressor, and an indoor cabinet contains the evaporator. The indoor cabinet also contains a furnace or the indoor part of a heat pump in many of the split-system air conditioners. The air conditioner’s evaporator coil is installed in the cabinet or main supply duct of this furnace or heat pump. A split-system is the most economical central air conditioner to install if your home already has a furnace but no air conditioner.

CENTRAL AC

In a packaged central air conditioner, the evaporator, condenser and compressor are all located in one cabinet, which usually is placed on a roof or on a concrete slab next to the house’s foundation. This type of air conditioner is also used in small commercial buildings. Air supply and return ducts come from the indoors through the home’s exterior wall or roof to connect with the packaged air conditioner, which is usually located outside. These can often include electric heating coils or a natural gas furnace. This combination of central heating and air conditioning eliminates the need for a  separate furnace indoors.

PACKAGED AC

Central air conditioning systems are thermostatically controlled and convenient to use.  

Central air conditioners circulate cool air through a system of supply and return ducts. Supply ducts and registers carry cooled air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the homed. The warm air then flows back to the central air conditioner through return ducts and registers.

Indoor humidity can cause many problems. Too much humidity in the air causes you to feel warmer, meaning it costs you more to run your air conditioning system longer. By selecting a thermostat with a humidity control feature, this could save you up to $300 per year and will also increase comfort in the home especially if you live in a humid area.

Air conditioners help to dehumidify the incoming air, but in extremely humid climates or in cases where the air conditioner is oversized, it may not achieve a low humidity. Running a dehumidifier in your home will increase your energy use, both for the dehumidifier and because the air conditioner will require more energy to cool your house. A dehumidifying heat pipe, which can be added as a retrofit to most existing systems, is a preferable alternative.

If you are considering adding central air conditioning to your home, the deciding factor may be the need for duct work.  

Central air conditioners are more efficient than room air conditioners. They are out of the way, quiet and convenient to operate. Purchasing an energy-efficient air conditioner will save money, and reduce you central air conditioner’s energy use. In an average air-conditioned home, an AC consumes more than 2,000 kilowatt-hours of electricity per year, causing power plants to emit about 3,500 pounds of carbon monoxide and 31 pounds of sulfur dioxide.
