If you’ve ever had to deal with a broken air conditioner, you know how frustrating it can be. Not only is it uncomfortable to be stuck in a hot, stuffy room, but it can also be expensive to get it fixed. That’s why it’s important to understand the different parts of an AC and how they work together. In this guide, we’ll cover the key components of an AC and provide tips for maintaining and troubleshooting them.
Compressor
The compressor is the heart of the AC system. It’s a pump that circulates refrigerant through the system, and it’s responsible for pressurising and cooling the air. When the thermostat senses that the temperature in the room is too high, it sends a signal to the compressor to turn on. The compressor then starts pumping refrigerant through the system, and as it passes through the condenser and the evaporator, it absorbs and releases heat.

Condenser
The condenser is a coil of tubes located outside the house. It’s responsible for releasing the heat absorbed by the refrigerant back into the outside air. As the hot refrigerant passes through the condenser, it gets cooled down by the surrounding air, and the heat is dissipated.
Common problems with the condenser
- Obstructions, such as leaves or debris, that block the flow of air
- Damage to the fins, which can reduce the surface area for heat transfer
- Leaks in the tubes, which can cause the refrigerant to escape
One of the most common problems with the condenser is obstructions that block the flow of air. The condenser is a coil of tubes located outside the house, and it’s responsible for releasing the heat absorbed by the refrigerant back into the outside air. If there are leaves or debris blocking the flow of air around the condenser, it can prevent the heat from being dissipated properly. This can cause the refrigerant to overheat, which can lead to damage to the system.
To prevent this problem, it’s important to keep the area around the condenser clean and free of obstructions. Make sure to clear away any leaves or debris that might be blocking the flow of air. If you have plants or shrubs growing near the condenser, trim them back to keep them from obstructing the flow of air.
Another common problem with the condenser is damage to the fins. The fins are the thin metal strips that surround the tubes of the condenser. They help to increase the surface area for heat transfer, which makes it easier for the heat to be dissipated. If the fins are damaged, it can reduce the surface area for heat transfer and make it harder for the heat to be dissipated. This can cause the refrigerant to overheat and lead to damage to the system.
To prevent this problem, it’s important to inspect the fins regularly and make sure that they’re in good condition. If you notice any damage, you can try to straighten the fins using a fin comb. If the damage is severe, it might be necessary to replace the condenser.
Leaks in the tubes of the condenser can also cause problems. If the tubes are leaking, it can cause the refrigerant to escape. This can lead to a decrease in the amount of cool air coming from the unit and an increase in energy bills. It can also cause the refrigerant to run out, which can be costly to refill.
To fix a leak in the tubes of the condenser, it’s important to get it checked out by a professional. A professional will be able to locate the leak and repair it using specialized tools and techniques. In the meantime, try to minimize the use of your AC to prevent further damage.
To keep the condenser in good working order, it’s important to clean the area around it regularly and make sure that there’s nothing blocking the flow of air.
Evaporator
The evaporator is a coil of tubes located inside the house. It’s responsible for absorbing heat from the air in the room and transferring it to the refrigerant. As the refrigerant passes through the evaporator, it absorbs the heat and cools down the air in the room.
Problems with the evaporator can cause
