Air Conditioner Compressor Replacement: Everything You Need To Know

Is your air conditioner not functioning properly, leaving you sweltering in discomfort during hot days? If so, it might be time to consider an air conditioner compressor replacement. However, before you proceed, it’s essential to understand the intricacies of air conditioning system installation and replacement procedures.

To assist you in this process, we have compiled a list of points to shed light on the associated cost of an air conditioner compressor and guide you in finding a reliable electrician in Brisbane, Upper Coomera, and Gold Coast.

Let’s delve into the details and learn all about aircon compressor replacement. 

Understanding the Air Conditioner Compressor

An Air conditioner compressor works tirelessly to keep your home comfortable during hot weather conditions. Therefore, it is often called the heart of your cooling system. Before you begin with your aircon compressor replacement procedure, let’s dive deeper into the role of the air conditioner compressor and how it operates:

Pressurising the refrigerant:

The compressor of an air conditioner plays a pivotal role in the cooling process. Its significance lies in its ability to compress the refrigerant, a specialised chemical that absorbs heat from the indoor air. As the compressor works its magic, the refrigerant transforms from a low-pressure gas to a high-pressure, high-temperature gas, facilitating effective heat exchange and cooling within the air conditioning system.

Enables heat exchange:

After the refrigerant is pressurised, it travels to the condenser coil. This condenser coil is located in the outdoor unit of your air conditioner. This is where the hot refrigerant releases its heat to the outdoor air, which ultimately causes it to condense into a high-pressure liquid.

Helps to circulate cool air:

The high-pressure liquid then moves to the indoor unit of your air conditioner, where it passes through the expansion valve. The purpose of this valve is to reduce the pressure of refrigerant and convert it into a cold, low-pressure liquid. This cool liquid moves through the evaporator coil. Here, it absorbs heat from the indoor air, cooling it down. This cooled air is transferred back into your home through the air ducts, eventually making your home environment a comfortable living space.

Signs That Show The Need For Air Conditioner Compressor Replacement:

Not recognising the signs that your air conditioner compressor might need a replacement can lead to costly repairs in the future. Thus, to save yourself from these costly repairs and potential discomfort, you should take a look at these indicators:

  • Warm Air: There can be a chance that your air conditioner is blowing warm air instead of cool, and the main reason behind this could be a faulty compressor. The inability to pressurise the refrigerant properly is usually the main reason for inadequate cooling.

  • Strange noises: You might notice unusual sounds coming from your air conditioner, such as grinding, squealing, or hissing noises. These noises may indicate internal compressor issues that require attention.

  • Frequent Cycling: It can be a sign of trouble if you notice your air conditioner turns on and off frequently. This is because the system could struggle to maintain the right pressure levels.

  • Tripped Circuit Breaker: A faulty compressor might draw excessive power, causing the circuit breaker to trip frequently. And you should know that this is a safety mechanism to prevent further damage.

  • Leaking refrigerant: If you observe that the refrigerant leaks around the air conditioner, it can be a clear indication of a problem. Remember that compressor issues can cause leaks and reduce the system’s cooling efficiency.

To tackle all these issues, you need to have a professional beside you. Reach out to our reliable electricians in Gold Coast at 0429 612 624.

The Importance Of Timely Aircon Compressor Replacement

A faulty air conditioner compressor not only disrupts your comfort but also leads to higher energy consumption. Thus, it is important to avoid any type of further damage to enjoy consistent cooling performance. If you avoid or delay the replacement, it could lead to more extensive repairs or even the need for a complete air conditioning system replacement.

What is the cost of aircon compressor replacement?

The cost of aircon compressor replacement depends on several factors. Here’s all you need to know about these factors when it comes to air conditioner compressor prices:

  • Type of Compressor: One of the major cost-affecting factors is the type of compressor your air conditioning system requires. Remember, different models and brands come with varying price tags.

  • System Size: Larger air conditioning systems may require more expensive compressors, affecting the overall air con compressor cost.

  • Labour Charges: The cost of hiring a qualified electrician or air conditioning technician to replace the compressor will also be a deciding factor in the total air conditioner compressor cost.


To know whether or not you need an air conditioner compressor replacement, you must consider the points mentioned above first. However, it is highly recommended to have an opinion of an experienced professional to make a wise decision.

Yes! If the compressor is the primary issue, replacing it is better than replacing the entire AC unit.

The average lifespan of an air conditioner compressor is around 10 to 15 years if it is taken care of properly.

No! Running your AC with a broken compressor is not recommended, as it can further damage your system.

The symptoms of a broken AC compressor include strange noises, warm air, frequent cycling, refrigerant leaks, and so on.
