This article describes the various components used in the central air conditioner installation. It also describes that if a component fails, the entire system can fail. It is a known fact that you need to know what you are buying. This actually helps save some money. Read this article till the end to know about the importance of each and every part of the central air conditioner, so if in future any problem arises you may be able to point it out.

Central air conditioning unit parts

A complete guide to the various components involved in the central air conditioner installation and how they are combined?
Your air conditioner and heater is a more complex system than most people think.
It’s definitely more than just a great ceiling fan. If a local HVAC expert came to solve your AC problem, you might have noticed that there are many parts of the system that you haven’t heard of before. Why do you need to take care of the basic business of your air conditioning system? This knowledge can make it easier to identify and fix problems when they occur.
Here we will look at the main parts of an air conditioning system and how each of them works to keep the room temperature in the house comfortable.
Central air conditioning unit configuration


The condenser is the outdoor unit of the air conditioning system. It is off the ground and is usually round or square.
The capacitor is a very important part of the system. It plays a role in releasing the heat absorbed by the refrigerant into the atmosphere. The refrigerant enters the condenser in the form of vapor, but turns into a liquid when cooled as it flows through the condenser and the condenser coil.


The compressor is a large AC component inside the capacitor and is invisible.
The compressor helps the condenser by increasing the pressure of the refrigerant enough to convert the high-pressure steam into a liquid.

Font group

Line array is a term referring to the copper wire that runs between the exterior and interior of the unit. These lines are used to transfer liquid or gaseous refrigerant from one component in the cycle to the next.

Expansion valve

The expansion valve assists the evaporator in the same way that a compressor regulates refrigerant pressure to aid the condenser. The expansion valve reduces the pressure of the coolant and allows it to return to the gas in the evaporator.


An evaporator essentially serves the opposite purpose of a condenser and is usually found at the top of an air conditioning system. The cooled liquid refrigerant enters the evaporator (via the line assembly) from the condenser and is filled with lower pressure.
When this happens, the liquid refrigerant returns to the gas, absorbing heat from the surrounding air and cooling the inside of the house.
After this is done, the gaseous refrigerant returns to the condenser and this cycle is repeated until your home is at a comfortable temperature.

Other ingredients

In addition to the parts listed above, there are several other components of the HVAC system worth mentioning.
Your thermostat does more than you think. It monitors the temperature of your home and maintains or starts the cooling process according to your settings.
When the air conditioning system draws in air to cool off, the air filter helps prevent pollen, pet dander, dust, or other particles from recirculating. Keeping these particles away from the air and system is very important to the functioning of the unit.
Problems with any of these components can cause the air conditioning system to fail, but regular maintenance can prevent these problems from occurring.
