The compressor is an important component of any air conditioning system, often referred to as the “heart” of the unit. Its primary role is to keep the refrigerant moving throughout the system, which is essential for the cooling process. Without a properly running compressor, an air conditioning system cannot perform its job. Hal Mechanical would like to highlight the important role of the compressor in an air conditioning system and identify key signs that may be a sign it is failing, helping homeowners maintain their system’s efficiency and longevity.
Role of AC Compressor
The compressor’s main purpose is to circulate refrigerant through the air conditioning system. It compresses the refrigerant, which increases the refrigerant’s temperature. The heated, pressurized gas then moves through the condenser where it releases its heat to the outside air, cools, and condenses into a liquid. This liquid refrigerant travels to the evaporator coil, where it evaporates into a gas again, absorbing heat from the indoor air and cooling it in the process. The second role of the compressor is to maintain the necessary pressure across the air conditioning system to ensure proper refrigerant flow and effective thermal exchange. It manages the pressure differential needed between the high-pressure and low-pressure sides of the system.
Signs of AC Compressor Failure
• Not Cooling Properly: If your air conditioner is running, but not lowering the temperature indoors, this can be one of the first signs that your compressor may be failing. Since the compressor is essential for the refrigerant cycle, any issue with it can greatly impact the system’s cooling performance.
• Strange AC Noises: Unusual noises coming from the air conditioning unit can often be a sign of compressor issues. A failing compressor can make grinding, rattling, or screeching sounds. These noises may suggest internal damage or that the compressor is having difficulty operating.
• Hard Starting: The compressor may struggle to start up, a condition known as hard starting. This issue can occur due to electrical problems, a weakened compressor motor, or issues within the compressor itself.
• Tripping the Circuit Breaker: If the air conditioner is causing the circuit breaker to trip repeatedly, this could be a sign of an overworking compressor. When compressors wear out, they can require more power to start and run, which can overload the electrical system.
• Warm Air Blowing from the Vents: If the air blowing out of your vents is warm instead of cool, this could be a sign that the compressor is not properly compressing the refrigerant, which is essential for heat exchange.
• Vibrations or Shaking When Starting: Also known as “hard starting,” if your outdoor air conditioner unit shakes or vibrates unusually on startup, it can indicate that the compressor is having trouble turning on, which might be due to electrical issues or internal damage.
