What is Central Air Conditioning?
Central air conditioners, often referred to as “central air” or “split-system air conditioning”, circulate cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills) carry cooled air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers. To learn how central air conditioners compare to other cooling systems, check out Energy Saver 101 Infographic: Home Cooling.
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 air-conditioned home will increase your energy use, both for the dehumidifier itself and because the air conditioner will require more energy to cool your house. A preferable alternative is a dehumidifying heat pipe, which can be added as a retrofit to most existing systems.
If you have a central air system in your home, set the fan to shut off at the same time as the compressor, which is usually done by setting the “auto” mode on the fan setting. In other words, don’t use the system’s central fan to provide air circulation — use circulating fans in individual rooms.
Types of Central Air Conditioners
A central air conditioner is either A) split-system unit (the most common for residential homes) or B) packaged unit (the most common for commercial buildings).
A split-system central air conditioner has:
- an outdoor metal cabinet containing a condenser coil and compressor, electrical components, and a fan.
- and an indoor evaporator coil which is usually installed on top of your furnace or air handler.
A single-stage system is quieter, and more efficient two-stage systems. A split-system central air unit offers reliable and consistent temperatures for the entire home. If your home already has a furnace but no air conditioner, a split-system is the most economical central air conditioner to install.
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 also is used in small commercial buildings. Air supply and return ducts come from indoors through the home’s exterior wall or roof to connect with the packaged air conditioner, which is usually located outdoors. Packaged air conditioners often include electric heating coils or a natural gas furnace. This combination of air conditioner and central heater eliminates the need for a separate furnace indoors.
How does Central Air Conditioning work?
Central air conditioners have a condensing unit that is located outside of your home. The condensing unit contains the air conditioner condenser coils, the compressor, and the condenser fan motor. The evaporator coils or cooling coils are located inside the home. They are mounted on top of a furnace or air handler. Either of these uses a blower fan motor, a circulation blower fan, and draws air through the return vent. The air blows past the evaporator coils and forces the air through your home’s venting. The room air is drawn back to the return. This is the airflow cycle.
Once the room air cools to the set temperature desired, the thermostat signals the circulation blower fan and condensing unit to shut off. Once the room temperature rises again, the system turns back on and repeats the operation.
3 Main Factors:
- Temperature Control
- Air Circulation
Benefits of a Central Air Conditioning system
- Indoor comfort during warm weather – Central air conditioning helps keep your home cool and reduces humidity levels.
- Cleaner air – As your central air-conditioning system draws air out of the rooms in your house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to the rooms.
- 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.
WHAT’S THE DIFFERENCE BETWEEN CENTRAL AIR AND A HEAT PUMP?
Central air conditioning systems use a closed-loop system that circulates refrigerant to cool the air. Central air specifically refers to a cooling system. The central A/C system is independent of your heating system. However, they’re usually are paired with a furnace or boiler because they share the same delivery system to cool and heat your home.
Heat pumps function the same as conventional air conditioners. The real difference is that a heat pump also can provide heating. A heat pump relies on the same basic system. In the summer, you can use a heat pump as an air conditioner, and in the winter, you can use it as a heater.
You can also pair a heat pump with a furnace or boiler. Heat pumps aren’t as efficient when temperatures drop below 25-degrees Fahrenheit. Furnaces can do a better job of heating the home at subfreezing temps.
You can improve your HVAC heat pump efficiency by pairing a heat pump with a furnace. Furnaces spread even heating from room to room. Combine that with a durable American Standard heat pump and you’ve got a hybrid system that keeps your family comfortable and, potentially, saves you energy.
With this dual-fuel option, the two systems share the heating load, but never function at the same time. Each system operates when it is most cost-effective. The heat pump will be the primary heating and cooling system. However, when the temperature drops below the heat pump’s ability to operate as efficiently as the gas furnace, the gas furnace will take over until the temperature rises enough for the heat pump to operate more efficiently.

How long does a central air conditioner last?
Hillside properly installs heat pumps in DE, PA, and MD that last an average of 15 years. Please note, there are a number of factors that can impact the life of your central air unit—the make and model, its usage rate, and whether or nor your central A/C has been maintained. Hillside’s HVAC professionals can extend the life of your air conditioning system with our annual tune-ups.
How much does a central air conditioner cost?
Central A/C pricing depends on several factors like the size of your home, model, installation requirements (e.g. existing or non-existing ducts).
