Understanding Central Air

Central air consists of a central unit that distributes cool air through a system of ducts. This unit typically includes an evaporator, compressor, and condenser. The evaporator coil cools the air, while the compressor and condenser work together to release heat outside.


Central air differs from heat pumps in their operation. While central air conditioners only provide cooling, heat pumps can both cool and heat spaces. Heat pumps extract heat from the air outside and transfer it inside during colder months, acting as a heating system when needed.


In central air systems, two key units of measurement are crucial: SEER and BTU. SEER (Seasonal Energy Efficiency Ratio) measures the efficiency of the cooling process, indicating how much energy is required to provide a specific cooling output. The higher the SEER rating, the more efficient the system. On the other hand, BTU (British Thermal Unit) measures the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit. It quantifies the cooling capacity of an air conditioner.

The size of your central air system plays a significant role in its efficiency. An oversized unit can lead to short cycling, where the system turns on and off frequently, increasing energy consumption.


On the other hand, an undersized unit may struggle to cool your home adequately, leading to discomfort during hot weather. Proper sizing is essential for maximizing energy efficiency and comfort.


Central air systems come in two main types: split systems and packaged systems. Split systems consist of an indoor unit and an outdoor condenser, connected by refrigerant lines. They are versatile and ideal for most homes.


Packaged systems, on the other hand, contain all components in a single outdoor unit. They are suitable for homes with limited indoor space or without a basement or attic for an indoor unit.

Comparison between Split Systems and Packaged Systems

  • Split Systems: Provide better temperature control as they can be zoned for different areas of the house.
  • Packaged Systems: Require less indoor space since all components are housed in one unit.

When deciding between split systems and packaged systems, consider factors like available space, zoning requirements, and installation costs. Split systems offer more flexibility but may require more extensive installation work.
