Have you ever wondered why your air conditioner is so effective at keeping your room cool and comfortable?
This blog will explain the air conditioner's working mechanism in a clear and simple manner.
There is no complicated jargon or confusing diagrams, just plain and simple language.
What Is an Air Conditioner?
An air conditioner (often called AC) is a machine that removes heat from your indoor space and throws it outside, making your room cooler and more comfortable.
You might think an AC creates cold air, but that’s not true. It works by pulling heat out of the air inside your room and releasing it outside. Once the heat is removed, the remaining air feels cool.
How Does Air Conditioning Work?
By removing the hot air and bringing in cooler air, air conditioners can help cool the air inside your house.
The system works on the simple principle that when a liquid becomes a gas it absorbs heat. The system works by removing heat from the room.
The same system keeps your fridge cold. Both systems use the same system to transfer heat from one location and release it elsewhere.
Step-by-step process of AC working mechanism:
1. Pulling in warm air:
The air conditioner starts by pulling the warm air from inside your room into the machine.
2. Cooling the air:
This warm air passes over cold metal pipes called evaporator coils. These coils cool the air down. At the same time, the system removes extra moisture from the air, which makes the room feel less humid.
3. Heat is absorbed by a special liquid (refrigerant):
Inside those coils, there’s a cold liquid called refrigerant. As the warm air passes over the coils, this liquid absorbs the heat and turns into a gas.
4. Getting rid of the heat:
The warm gas (now full of the heat from your room) is sent to the outdoor part of the air conditioner. There, it goes through a compressor and a condenser. These parts help release the heat into the outside air and turn the gas back into a cool liquid.
5. Bringing cool air back:
The cool liquid goes back into the system to repeat the cycle. Meanwhile, the cooled air inside the unit is blown back into your room. This brings down the temperature and makes the room feel more comfortable.

What do the separate air conditioning components do?
Air conditioning systems consist of several key components that work together to cool indoor air.
A special liquid refrigerant circulates through coils, playing a vital role in this process.
For the system to function properly, three essential components must be present in the refrigerant circuit:
1. Evaporator:
Warm indoor air is drawn in and passes through an expansion valve, which controls the amount of refrigerant entering the system.
The air is then blown over the chilled evaporator coils. These coils absorb heat from the air, causing the refrigerant inside them to evaporate and turn into a gas.
The cooled air is then circulated back into the room while the heated gas moves on to the compressor.
2. Compressor:
The compressor serves as the system's pump. It compresses the gaseous refrigerant, reducing its volume while increasing its pressure and temperature, preparing it for the next phase condensation.
3. Condenser:
The hot, pressurized gas flows into the condenser unit located outside. Here, the refrigerant releases the absorbed indoor heat into the surrounding outdoor air. As the heat dissipates, the refrigerant condenses back into a liquid form.
This cycle then repeats, as the cooled liquid refrigerant is sent back to the evaporator to continue cooling your indoor space.
Types of Air Conditioners
Knowing the different types of air conditioners can help you pick the right one for your home or space.
Here’s a simple breakdown of the most common ones:
1. Central Air Conditioner
This type is great for cooling big houses or large areas. It has a main unit that cools and removes moisture from the air, then spreads it through ducts to different rooms. It keeps the whole house cool evenly and works well if you want to cool many rooms at once.
2. Window Air Conditioner
This is a small, all-in-one unit that fits in a window or a hole in the wall. It blows cool air inside and pushes hot air outside. It’s a good choice for cooling one room and is easy to install.
3. Split Air Conditioner
Also called a ductless mini split, this type has two parts one outside and one (or more) inside. They’re connected by cables and pipes. It’s energy-saving and lets you set different temperatures in different rooms.
For example, the Better Air Fresh 1.5 Ton DC Inverter Air Conditioner from Better Appliances offers a reliable and efficient cooling solution with its advanced inverter technology, perfect for homes that need individual room temperature control.
4. Portable Air Conditioner
This unit can be moved around. It sits on the floor and has a hose that pushes hot air outside through a window or wall. It’s good for rooms where a fixed AC isn’t possible or when you need temporary cooling.
5. Hybrid or Dual Fuel Air Conditioner
This system uses both electricity and gas. In hot weather, it works like a normal AC. When it’s cold, it switches to gas heating, which saves electricity and keeps your home warm.
6. Geothermal Air Conditioner
This type uses underground pipes to exchange heat with the earth. It’s very energy-efficient and works for both cooling in summer and heating in winter. It costs more to install but saves money over time and is better for the environment.
Which Gas Is Used in AC?
The gas used in air conditioners is called a refrigerant. This gas plays an important role in cooling by helping to move heat out of your room.
There are different types of refrigerants, and each one has its own features and effects on the environment. Here are the most common types:
CFCs (Chlorofluorocarbons): these were gases now mostly banned because of their harms to the ozone layer.
HCFCs (Hydrochlorofluorocarbons): these are slightly better than CFCs but are still in the process of being phased out.
HFCs (Hydrofluorocarbons): common in newer ACs especially because they do not harm the ozone layer, they do however, affect global warming.
HCs (Hydrocarbons): these are more eco-friendly options like R-290 and R-600A and safe and energy efficient.
HFOs (Hydrofluoroolefins): Latest type; very low environmental impact and becoming popular in modern systems.
Advantages and Disadvantages of Air Conditioners
Thinking about buying an air conditioner or a split system for your home or office?
Before you decide, it’s important to understand both the benefits and drawbacks of using an AC.
In this post, we’ll break down the pros and cons, so you know exactly what to expect.
Advantages of Using an Air Conditioner
1. Comfortable Temperature All Year Round
One of the biggest benefits of an AC is that it keeps your room at a comfortable temperature no matter what the weather is like outside.
In summer, it cools down your space.
In spring or autumn, many systems can also heat the room if it gets chilly. This means you can always enjoy a pleasant indoor environment.
2. Cleaner Indoor Air
Air conditioners can help improve air quality, especially in cities or industrial areas where outdoor air is full of dust and pollution.
With an AC, you don’t need to open windows for ventilation, so you get cool, filtered air that’s cleaner and healthier to breathe.
3. Better Humidity Control
Some AC models come with a dehumidification feature, which helps maintain the right level of moisture in the air.
This is great for your comfort, and it can also help prevent Mo ld growth and reduce the stuffy feeling that comes with too much humidity.
Disadvantages of Air Conditioners
While ACs offer many benefits, there are a few things to be aware of, especially when they’re not used or maintained properly.
1. Poor Maintenance Can Lead to Health Issues
If the AC isn’t cleaned regularly, dust, bacteria, and viruses can build up inside it.
When the system runs, these harmful particles can be spread through the air, leading to allergies or respiratory issues.
2. Dry Indoor Air
Air conditioners tend to dry out the air, which can make your skin or throat feel dry, especially with constant use.
It’s a good idea to use a humidifier in the same room to keep the air balanced and comfortable.
3. Noise from the Outdoor Unit
Although the indoor unit is usually quiet, the compressor in the outdoor unit may make some noise during operation. Luckily, in most setups, you won’t hear much of it from inside the room.
Maintenance and Repairs: What You Need to Know
1. Regular Cleaning is a Must
To keep your AC running efficiently and safely, regular cleaning and maintenance are important.
You can clean the air filters yourself if you know how your model works.
Or you can call a professional, who can do a full cleaning and system check in 30 to 60 minutes.
2. Don’t Try to Repair It Yourself
If something goes wrong with your AC, it’s best to call the service team. Trying to fix it yourself can be risky and might cause more damage.
Common issues include:
Overheating of the compressor due to long use
Dirty grills or radiators, which block airflow
These problems are often easy to fix by simply cleaning the parts.
3. Not Cooling Properly? Check the Filters
If your AC isn’t cooling as well as it used to, the air filters may be clogged with dust. Cleaning or replacing them can often solve the problem right away.
