The 5 Basic Components of an Effective Air Conditioning System

27 May 2020

An effective, fully functional air conditioning system can readily remove warm air and replace it with much cooler air. It is usually a part of a complete system of heating, ventilation, and air conditioning that is also known as HVAC.

The ability of an air conditioning system to cool and dehumidify rooms or spaces is important to achieve a comfortable interior environment. Additionally, this cooling capability is vital in maintaining the optimal performance and temperature of heat-producing electronic devices like computer servers and power amplifiers. 

For it to be effective in cooling or even heating, your air conditioning system must possess the following basic components. 


The compressor is known as the engine or the heart of an air conditioning system. This specific component directly operates with a working fluid, a substance that can transform from the gas form into the liquid form. The main task of the compressor is to process and convert low-pressure gas into a high-pressure one, which also possesses a high temperature. Whenever the compressor performs this conversion process, the gap regions between the molecules are narrowed down to create an energised gas. Ultimately, this component releases energised gas or refrigerant and transfers it to the condenser.

Condenser Coil

Once the energised gas or refrigerant is transferred to the condenser, it is then converted back into liquid form. This conversion is done through a fan that is fitted into the condenser coil, which cools down the energised gas and transforms it back into a low-pressure liquid. The liquid product from the condenser is then taken to the evaporator. Both the compressor and condenser of your air conditioning system are frequently located on the outside of your property.


Unlike the first two components, the evaporator of an air conditioning system is located inside your property, especially near the furnace. This component is usually connected with the condenser through a thin pipe. The decreasing pressure from this component allows the conversion of the low-pressure liquid into a gas form again. Consequently, the working fluid or refrigerant removes the heat from the gas and cools it off. Once the process is done, the working fluid comes out of this component in the form of a gas and gets compressed by the compressor again. All the previously mentioned processes happen cyclically whenever the system is powered on.

Air Handler and Blowing Unit

The dissemination and distribution of cool air all over your property are being handled by the air handler and blowing unit of your air conditioning system. They are also responsible for drawing room air to the evaporator. These components work best with a duct system, which enables great airflow passage and circulation in a room.


The thermostat of your air conditioning system helps you maintain and control the air temperature of your room or space. They do this functionality by regulating the heat energy that flows inside and outside of your system. For added functionality and convenience, thermostats can be manually or automatically, which depends solely on the included features of an air conditioning system. When you regularly maintain these components, you are assured of an air conditioning system that can work optimally for a very long time.
