Determining the Possible Causes for a Noisy AC

Find out How to Troubleshoot an Air Conditioner That Produces Unusual Noises

A well maintained air conditioner is a reliable and trouble-free one. Unfortunately, many homeowners underestimate the importance of properly taking care of their AC units, and that’s how most of the problems start. One of the most common issues with AC systems are unusual noises. A system that is producing disturbing sounds is most likely a system that needs immediate assistance. Here are some common noises and what they most likely mean.

air conditionerBuzzing
Every AC makes a certain buzzing noise when open or close. This is usually generated by the motor that opens and closes the AC’s frontal hatch. However, if the buzzing sound continues even after the hatch has open, then the compressor motor may show signs of failure. Have the unit inspected by a professional AC service provider.

Bubbling or Hissing
If you hear a bubbling sound coming from your unit, it may signal a refrigerant leak. A hissing noise, on the other hand, may indicate a major loss of refrigerant. You should stop your unit immediately and contact an air conditioning maintenance service provider.

Clanking or Banging
This are sounds that are usually generated by a loose motor mount or a broken component inside the compressor’s compartment. We suggest you have your system inspected as soon as possible.

All compressors are equipped with safety mechanisms that prevents them from accumulating dangerously high pressures. Unfortunately, even these safety mechanisms can fail sometimes. When this happens, you’ll likely hear a screeching noise. Shut off your unit immediately as these high pressures can cause irreparable damage to your compressor.

This is a sound typically caused by a broken belt or loose bearing. It can also be the fan hitting a piece of debris that fell inside. Turn off your unit, remove the top panel, and check for visible problems. If you can’t find anything that may cause the disturbing sound, call someone that specializes in air conditioning maintenance.
