Is Your AC Making a Clicking Noise?

Reasons Why & Troubleshooting Tips

You’re sitting at home on a hot summer day, enjoying the cool breeze from your AC, when suddenly — click, click, click. Like anyone else, you may brush it off at first as another household noise, but as the clicking continues, it starts to feel like your air conditioning is trying to tell you something. Because it is.

While some clicking could be normal (like when your system powers up), frequent or loud clicking might be a sign that something’s not right.

If your AC is clicking, here’s what might be causing it and, more importantly, what you can do about it.

4 Common Causes of AC Clicking Sounds

Electrical Problems

Clicking sounds from your AC could stem from electrical issues, like a failing capacitor or a faulty relay switch (the toggle that controls the flow of electricity in your unit). If either part malfunctions, it may cause persistent clicking noises. If left unaddressed, electrical problems could prevent the system from turning on or functioning properly.

Bent or Obstructed Fan

The fan inside the condenser unit can sometimes get bent or blocked by debris, creating a clicking noise as it struggles to rotate. This usually results from wear and tear or a lack of proper maintenance. If the blades are misaligned or obstructed, the fan may eventually stop working altogether.

Mechanical Issues

Your air conditioning system relies on several moving parts to function correctly and collaboratively. If components like the blower motor or belts become misaligned or worn down, they produce clicking sounds as they struggle to operate. Over time, ignoring these mechanical problems can lead to bigger repair needs.

Loosened Compressor Parts

The compressor is the heart of your AC system, responsible for circulating refrigerant and maintaining cooling functions. If internal components within the compressor become loose, they can cause a clicking sound during operation. Since compressor repairs can be complex, it’s often best to have a professional diagnose and resolve the issue.

Expert Troubleshooting Tips

Before calling a technician, you might try these simple troubleshooting steps:

• Check for any visible debris around the outdoor unit and clear it away if possible.
• Inspect the fan blades for damage or obstructions (if damaged, contact an expert).
• Turn off the AC and restart it to see if the clicking noise persists.
• Ensure the thermostat is functioning properly and set to the correct mode.

When To Call a Professional

If troubleshooting doesn’t resolve the issue or if you’re unsure about handling electrical or mechanical components, it’s best to call an HVAC professional. A trained technician can accurately diagnose the problem and prevent further damage to your system.
