Why Is My Compressor Making a Noise?
Noises from compressors may be indications of operational issues that can lead to equipment failure. Mechanical issues, air leaks, vibration and mounting problems can all cause compressor noises. Knowing how to differentiate between normal operational sounds and warning signs is crucial to prevent costly repairs and accidents.
Diagnosing Noise Issues
Determine the cause of the compressor noise and try to troubleshoot the problem before you get help from a professional. Steps you can take include:
- Visual inspection: Check for damaged hoses or worn components. See if the compressor has visible loose parts and secure them in place if you can.
- Listening techniques: Use a sound detection tool to identify the main source of the noise more accurately.
- Professional evaluation: For persistent and severe noise issues, consult a professional technician as soon as possible.
Here are a few common types of air compressor noises and potential causes.
High-Pitched Noise
If you hear high-pitched sounds from the compressor, it can be a sign of issues with its motor or bearings. An air compressor making a high-pitched noise indicates the possibility of a malfunctioning pressure switch.
Rattling Noise
Loose components and debris can result in your air compressor making a rattling noise. A broken fan blade is another possible cause that poses a more severe problem. Improper installation of the air filter can also create rattles inside the unit.
Hissing Noise
When refrigerant gas escapes from the compressor, it produces a hissing sound. A leak in the air system can be dangerous to people and animals when inhaled or ingested, as well as to the environment. A hissing noise can indicate a problem with the pressure relief valve.
Clanking Noise
Damaged air condenser fans can cause clanking sounds against the condenser coil. When you hear this noise, it can be a sign that your outdoor unit is on the verge of breaking down. Depending on the extent of the damage, you may be looking at a possible replacement of the compressor or the entire HVAC system.
