Troubleshooting AC Clicking Noise When Turned On

Are you hearing an ominous clicking noise from your ACunit when you turn it on? This can be a worrying sign that something’s wrong. Learn the three common causes of AC clicking noises and what to do about them.

Quick Summary

If your air conditioner is clicking when turned on, it is likely due to one of three common causes: loose parts in the compressor, electrical issues, or a faulty fan unit. Loose parts in the compressor, such as a loose bolt, can cause clicking noises from outside the house. Most air conditioning systems click once when they startup, which is entirely normal. If the clicking noise persists, the fan unit might be the cause. A faulty fan unit can often be easily spotted and diagnosed by a qualified technician.

In order to troubleshoot clicking noises coming from an air conditioning system, first check to ensure all parts are properly secured and that any exposed wiring is properly insulated. Then, check to make sure the system is set to the correct settings. If the clicking noise persists, consider calling an AC technician to inspect the system and identify the source of the noise.

Have you ever heard a clicking sound coming from your air conditioner when it starts? Don’t worry, this sound is usually normal and means your AC is working as expected. However, it can also be indicative of various issues and can be an annoyance, so it’s important to investigate. Here are the top three reasons your air conditioning could be making a clicking noise when switched on and some simple solutions.

1. Loose Parts in the Compressor

If the noise is coming from outside the house, it could be stemming from the compressor. Sometimes, clicking noises result from loose bolts or other metal parts that need to be tightened. If it’s a recurring sound, you should call a certified HVAC expert to inspect and repair the system.

It’s common for AC systems to click once when they turn on. If a loud, persistent clicking noise is occurring, you may have an electrical issue.

3. It’s Your Fan Unit

Another potential cause of a clicking noise when your AC is on is an issue with the fan unit. If the unit is malfunctioning, you may hear a clicking sound. To troubleshoot, try checking the fan blades to make sure they’re spinning correctly. You can also try cleaning them to remove debris. If the noise persists, it’s best to call an HVAC specialist.

  • Check the compressor for loose parts.

I have been doing repair and maintenance for many different kinds of air conditioners for over five years. One thing I often see is when people turn on their AC, there could be a clicking noise coming from their outside unit.When this happens, there are three common causes of this issue.

The first is that there are loose parts in the compressor. If you notice clicking coming from outside of your home, you may need to check the compressor. It’s possible there’s a loose bolt or other part causing the clicking noise.

Second is that it might be electrical issues. Most ACs emit a clicking noise once when they start up, so it’s not uncommon. In some cases the clicking may be part of a more complex issue.

Lastly, the clicking may be coming from your fan unit. This component is a vital part of your air conditioner, and it’s possible it’s coming loose or developing an issue as it ages. Be sure to have a professional take a look so you can make sure your ac is functioning properly.

If you are hearing clicking noise when you turn on your ac, there could be an issue with your compressor or your fan unit. I recommend having a professional come take a look so you can make sure that your air conditioner is working correctly.
