Air conditioning is an essential part of modern life, and with it, people have been enjoying cool and comfortable indoor spaces during hot and humid weather. It provides a system that helps regulate indoor temperature and humidity levels to create a more relaxed environment.

An air conditioning system is not only essential for personal comfort but is also needed for optimal health. The fact is, it helps to reduce the risk of heat-related illnesses.

With all the benefits one may derive from using air conditioners, whether a split system or portable air conditioner, only a few people can actually boast of knowing how air conditioning works. It is intended that this article will guide you to learn more about that great appliance that supports you so well through all seasons.

Components of an Air Conditioning System

You will find out that air conditioning systems have four basic components: compressor, condenser coil, expansion valve, and evaporator. Each of these air conditioning components plays an essential role in the process of cooling air.


The compressor is the core of the air conditioning system as it is responsible for pumping refrigerant gas from the evaporator to the condenser.


The condenser is responsible for releasing the absorbed heat from the indoor air to the outdoor air. It is made up of a network of tubes, and it is the point at which the refrigerant gas releases heat and then allows it to condense into a liquid.

Expansion valve

The expansion valve is a valve that regulates the flow of refrigerant liquid, which is first kept in the condenser and then moved to the evaporator. It causes a reduction in the pressure of the refrigerant liquid and gives room for its expansion which causes the air to cool.


The evaporator coil absorbs heat from the indoor air, which cools the air. It comprises a network of tubes through which the refrigerant liquid eventually evaporates into a gas. These four components work synergistically to cool the indoor air of the room where the air conditioner is installed.

The compressor squeezes the refrigerant gas, which is then pumped to the condenser; from there, it is released as heat to the outdoor air. The refrigerant liquid is allowed to flow through the expansion valve, reducing its pressure and temperature before it enters the evaporator.

While in the evaporator, heat from the indoor air is absorbed by the refrigerant liquid, cooling the air. As soon as the air is cooled, it is circulated back into the room. At this point, the refrigerant gas returns to the compressor to repeat the cycle. Understanding the basic components of your air conditioner will assist you in providing proper maintenance and care for the system.

Basically, an air conditioning system works by removing heat and moisture from the air. It also dehumidifies indoor spaces during the process of cooling hot air. This process involves the four basic components of an air conditioning system: compressor, condenser, expansion valve, and evaporator.

Types of Air Conditioning Systems

There are different kinds of air conditioning systems available today. It takes going through each of these if you are interested in finding out what works best for you. This is necessary because each system has its advantages and disadvantages. A careful look at facts about them can help you greatly if you are still deciding what type you should buy right now.

Central air conditioning systems

Central air conditioning systems are considered the most common type of system. They are designed to work on entire homes or buildings by replacing hot air within them with cool air.

They are made of a large compressor unit placed outside the building and an air handler unit placed within it. Centralised air conditioning systems can be effectively used to cool large spaces. However, you should note that installing and operating can be pretty expensive.

Window units

Window units are another type of air conditioning system that is commonly used. They consist of a single unit affixed or mounted in a window. Quite a number of people settle for this type because they are generally less expensive than central air conditioning systems.

They are also relatively easier to install than central air conditioning systems. However, this type can only be effectively used for cooling a single room. They can also be noisy and obtrusive.

Portable air conditioning units

Many people find portable air conditioning units a versatile option as they can be moved from room to room. They are not as expensive as the window units and also do not require any installation.

However, remember that they are generally less powerful than central air conditioning systems or window units. When they are placed to cover large spaces, they may be unable to work effectively.

You can get more information about these different types of air conditioning systems. The more you understand them, the better the chances of finding what will work best for you and within your budget. Understanding them well enough will also help you prepare for whatever maintenance implications you may have to handle.

Each of these systems has its advantages and disadvantages. Take some time also to consider factors such as cost, efficiency, and the size of the space required to be cooled before selecting an air conditioning system.

Maintenance and Care of Air Conditioning Systems

Regular maintenance and proper care for air conditioning systems are critical to ensure they work efficiently and effectively. The following are some of the reasons you should consider this important:

Reduced energy costs

With proper maintenance and care, your air conditioning system may be assisted to improve its efficiency, reduce energy costs and help you save money.

Longer lifespan

If you can maintain and care for your air conditioning system regularly, it will help you extend its lifespan. This means you can use it for several years while enjoying the services it renders you.

Improved air quality

When your air conditioning system is well-maintained, it can help improve indoor air quality. This will reduce the risk of respiratory problems and other health issues emanating from its use over time. The following are some valuable tips for maintaining and caring for your air conditioning system:

Change air filters regularly

It would be best if you considered changing the air filters of your air conditioning system every one to three months. This, of course, will depend on the usage of the unit. If the filters are dirty, it can cause the unit to work harder, reducing its efficiency in the process.

Clean the condenser coil

The condenser coil needs to be cleaned at least once a year. This will help to get rid of any form of dirt or debris that may have accumulated from use.

Keep the outdoor unit clean

The outdoor unit should be clean and debris-free, such as leaves and twigs. This can help to improve the efficiency of the system.

Common Problems with Air Conditioning Systems 

You may encounter some problems with your air conditioning system. You don’t have to panic when this happens because, in most cases, they are things you can quickly attend to yourself as long as you have been maintaining the system properly. The following are some common problems and how to address them when they occur;

The air conditioning system is not turning on

When this occurs, the first thing to check should be the thermostat batteries and settings, circuit breakers, and then the power supply to the unit.

Insufficient cooling

Look at the air filters, condenser coil, and refrigerant level. If nothing works, you may schedule maintenance with a licensed professional.

Strange noises

Strange noises may result from loose parts, such as screws or bolts. This can be a result of a problem with the motor or compressor. Try and schedule maintenance with a licensed professional to address the issue adequately.

Call a Licensed Professional to Fix Your Unit

If you enjoy your air conditioning system, consider its maintenance and care. If your system needs some TLC, you should call a licensed professional and make it routine. This is one major step that will help you continue to enjoy using your air conditioner.
