Signs Your AC Compressor May Need to be Replaced

A malfunctioning AC compressor can wreak havoc on your Cornelius, NC, home’s cooling system, so it’s important to replace it as soon as possible. Watch out for these common warning signs to ensure a faulty component doesn’t turn into a complete system failure.

Poor Airflow or Ineffective Cooling

When your air conditioner isn’t producing much cool air, a dirty filter or evaporator coil is usually the prime suspect. If you’ve kept up with proper AC maintenance, however, it may be a sign that the compressor isn’t functioning properly. A worn-out compressor may struggle to compress the refrigerant in the system, reducing its ability to transfer heat. This makes the whole condenser unit less effective, resulting in a less comfortable home and higher monthly energy bills.

Frequent Tripped Circuit Breakers

If the circuit powering your air conditioner is tripping repeatedly, it’s time to shut it down and schedule an urgent repair call. While this can happen for many reasons, it often indicates a problem with your AC compressor. A bad compressor is more likely to overheat, causing it to draw more power than expected. This, in turn, increases the unit’s electrical load, tripping the breaker and abruptly shutting down the system.

Hard Starting or Noisy Operation

When your AC compressor is in poor condition, it may vibrate excessively during startup and take longer to get running. This is known as hard starting, and it could be a clear indicator that your compressor is about to fail. If the compressor mounts are wearing out, you may also hear loud rattling or rumbling noises during operation. Another sign that shouldn’t be overlooked is a ticking sound at the beginning and end of each cooling cycle. This is often caused by a bad electrical relay preventing the compressor from cycling on and off normally.
