5 Signs that Your Air Conditioning System Needs Repair

Having a functional air conditioning system is crucial for maintaining indoor comfort, especially during summer. The scorching heat during the summer months can be unbearable without a reliable air conditioning system. 

However, like any other appliance, air conditioning systems can develop faults over time. These complex appliances require regular maintenance and repair to function effectively. Neglecting your air conditioning system can lead to decreased performance, increased energy bills, and even a breakdown. Therefore, it is important to be aware of the signs that your air conditioning system needs repair. Whether it’s poor airflow, strange noises, high humidity levels, warm air, or high energy bills, recognising these signs early on can save you from a lot of discomfort and expense. 

In this article, we’ll discuss these common signs that your air conditioning system needs repair and how air conditioning service and air conditioning installation can help.

How Does Air Conditioning Work?

Air conditioning works by removing heat and humidity from the indoor air and circulating cool, dehumidified air back into the room. This process requires the use of a complex system of components that work together to ensure optimal indoor comfort. An air conditioning system typically consists of four main components: a compressor, a condenser, an evaporator, and an expansion valve.

The process starts with the compressor, which compresses the refrigerant gas, increasing its temperature and pressure. The compressed gas then flows to the condenser, where it releases the heat it has absorbed into the outdoor air. This causes the gas to condense into a high-pressure liquid.

The high-pressure liquid then flows through the expansion valve, where it rapidly expands and evaporates into a low-pressure gas. This process causes the refrigerant to absorb heat from the indoor air, lowering the temperature of the air.

The low-pressure gas then flows to the evaporator, where it absorbs more heat and humidity from the indoor air. The evaporator contains a set of coils that are filled with the cool refrigerant gas. As warm indoor air is blown over the coils, the refrigerant absorbs the heat and humidity from the air, cooling and dehumidifying it.

Finally, the cool, dehumidified air is blown back into the room through the air conditioner’s vents or ducts. The cycle then repeats itself, with the refrigerant flowing back to the compressor to start the process all over again.

5 Signs that Your AC System Needs Repair 

  1. Poor Airflow

Poor airflow is a common sign that your air conditioning system needs repair. This issue is often caused by a dirty air filter or a faulty blower motor. While a dirty air filter restricts the airflow and makes it harder for the system to cool the air effectively, a faulty blower motor can cause weak or inconsistent airflow. A professional air conditioning service in Sydney can replace the air filter or repair the blower motor to restore optimal airflow.

  1. Strange Noises

If you hear unusual noises coming from your air conditioning system, such as rattling or squealing, it is a sign that something is wrong. These noises could be caused by a loose component or a faulty motor. 

For example, a loose fan blade could cause a rattling noise, while a worn-out motor could cause a squealing noise. It is important to have your air conditioning system checked by a professional to prevent further damage and ensure safe operation.

  1. High Humidity Levels

Is your air conditioning system not properly removing moisture from the air? If so, this could lead to high humidity levels in your home and cause discomfort and potentially lead to mold growth. 

For instance, a clogged drain line or a malfunctioning evaporator coil can prevent the system from removing moisture effectively. An air conditioning service can identify and repair the problem to restore optimal humidity levels.

  1. Warm Air

If your air conditioning system is blowing warm air instead of cool air, it could be due to a refrigerant leak or a faulty compressor. A refrigerant leak can cause the system to lose its ability to cool the air effectively, while a faulty compressor can prevent the refrigerant from circulating properly. If you’re unsure if your system has this issue, an air conditioning installation or service technician can diagnose the issue and recommend the necessary repairs or replacement.

  1. High Energy Bills

Did you notice a sudden increase in your energy bills without any changes in your energy usage? That could be due to an inefficient air conditioning system. An outdated air conditioning system or ductwork can cause energy waste and inefficiency. The good thing is that a professional air conditioning service can perform a system inspection to identify areas where your system can be optimised for energy efficiency, such as replacing outdated components or upgrading to a more energy-efficient system.
