AC Compressor Guide

By Travis Baugh

An AC compressor is a vital component in any air conditioning system, playing a key role in cooling your home by circulating refrigerant and enabling heat transfer. In this article, we’ll dive into what an AC compressor is, how it works, and go through the replacement process for an air conditioning compressor.

What Is An AC Compressor?

An AC compressor is a crucial component of an air conditioning system that plays a key role in cooling your home. It is responsible for compressing and circulating refrigerant through the system, which allows the heat from inside your home to be absorbed and released outside. 

How Does An AC Compressor Work?

The compressor is typically located in the outdoor unit of the air conditioner. It takes in low-pressure, cool refrigerant gas from the evaporator coil inside the house and compresses it, turning it into a high-pressure, hot gas. This high-pressure gas is then sent to the condenser coil (also in the outdoor unit), where it releases the absorbed heat and cools down, turning back into a liquid. The refrigerant then travels through the system again, repeating the cycle of heat absorption and release, which ultimately cools the indoor air.
 
In simple terms, the AC compressor helps regulate the flow of refrigerant in the system and is essential for the cooling process, making it one of the most important parts of an air conditioner.

Signs of a Failing AC Compressor

A failing AC compressor can cause a range of issues that affect your cooling system’s performance. Here are some common signs to watch for:
  • Warm Air: If your AC starts blowing warm air instead of cool air, the compressor may not be circulating refrigerant properly, leading to inadequate cooling.
  • Strange Noises: Grinding, squealing, or clanking noises from the outdoor unit could indicate that the compressor’s internal components are damaged or failing. 
  • Lack of Cool Air Flow: If the airflow from your AC seems weak or inconsistent, it may signal a compressor issue, as the compressor is responsible for pushing refrigerant through the system.
  • Tripped Circuit Breaker: A failing compressor may cause the electrical circuit to trip frequently, as it struggles to start or operate.
  • Increased Cooling Bills: If your AC compressor isn’t functioning properly, the system may run inefficiently, leading to higher energy consumption and increased utility costs.
  • Visible Leaks: Refrigerant leaks around the compressor or other AC components could be a sign that the compressor is damaged or malfunctioning.
If you notice any of these signs, it’s important to contact your local Bryant dealer for a thorough inspection and potential compressor replacement.

Seven Steps of the Air Conditioner Compressor Replacement Process

Replacing an AC compressor is a complex task that requires the expertise of a professional HVAC contractor like your local Bryant dealer.  The compressor is a critical part of the cooling system, and improper installation or handling can lead to system failure or damage. Here’s a step-by-step guide on what the air conditioner compressor replacement process typically looks like when working with an HVAC professional:

1. Initial Inspection and Diagnosis

The HVAC contractor will start by thoroughly inspecting your air conditioning system to confirm that the compressor is indeed the issue. This often involves checking for signs of compressor failure (like strange noises, lack of cooling, or refrigerant leaks). The contractor will also evaluate the entire system to ensure there are no other underlying issues (e.g., electrical problems, refrigerant leaks, or damage to other components like the condenser or evaporator coil).

2. Turn Off Power and Remove Old Compressor

The technician will first turn off the power to the system to ensure safety during the replacement. The HVAC contractor will then safely remove the refrigerant from the system, following proper guidelines to avoid environmental hazards. Refrigerant must be recovered and disposed of correctly. The old compressor will be disconnected from the refrigerant lines, wiring, and any other components it’s connected to, like the capacitor or fan motor.

3. Remove and Replace the Compressor

The technician will remove the faulty compressor from its housing or compartment within the outdoor unit. Depending on the system, this may require unbolting the compressor and disconnecting it from various mounting brackets. Once the old compressor is removed, the new unit is carefully installed. This involves connecting the refrigerant lines, electrical wiring, and ensuring the compressor is securely mounted in place.

4. Recharging the System and Checking Refrigerant Levels

The HVAC contractor will then recharge the system with the proper amount of refrigerant. They will ensure the refrigerant charge matches the manufacturer’s specifications for optimal performance and efficiency. The technician will also perform a thorough check for any refrigerant leaks around the compressor and other connections to ensure everything is properly sealed.

5. Electrical Checks and System Testing

The technician will verify all electrical connections are secure and properly hooked up to the new compressor, including connections to the thermostat and the capacitor (if necessary). After everything is connected and secured, the technician will power up the unit and perform a full system test. This includes running the AC through a cooling cycle, monitoring the compressor's operation, and ensuring it’s functioning properly without any issues like unusual noises or improper cooling.

6. Final Inspection and Clean-Up

Once the system is confirmed to be running correctly, the HVAC contractor will do a final inspection, ensuring all components are in place and working as they should. The technician will clean up any debris, refrigerant, or other materials used during the replacement process. They will also provide you with the old compressor for disposal or recycling, if required. Some HVAC contractors may also provide documentation of the repair and a warranty on the new compressor, outlining any maintenance recommendations or next steps.

7. Post-Installation Advice

After the replacement, your HVAC contractor may offer tips on maintaining your AC system to ensure it runs efficiently and extends the lifespan of your new compressor. This could include recommendations for regular AC maintenance, air filter changes, and other system care practices.

A/C Compressor Cost

The cost of an A/C compressor can vary significantly depending on factors such as the make and model of your system, labor costs, and whether you choose to replace the entire compressor or just specific components. On average, the cost of replacing an A/C compressor typically ranges from $800 to $2,500, including both parts and labor. The price for just the compressor unit itself can be anywhere from $400 to $1,500, depending on the brand and type of refrigerant your system uses.
 
Labor costs generally account for a significant portion of the overall price, ranging from $300 to $1,000, as replacing a compressor involves several steps, including evacuating refrigerant, removing the old compressor, installing the new one, and recharging the system.
 
Additional factors that could influence the cost include the age of your HVAC system, whether you need to replace other parts (such as the accumulator or expansion valve), and the need for refrigerant recharging. It’s important to get multiple quotes and consult a professional HVAC technician to ensure the proper diagnosis and fair pricing
