Why is my air conditioner making clicking noises? If your air conditioner is clicking, it’s essential to have it checked out by a professional to determine the root cause of the problem and get it fixed before it becomes more serious. There can be various reasons why an air conditioner might start making clicking noises, from an issue with the compressor to something wrong with the fan. By having your unit checked out, you can find out what’s causing the problem and take steps to fix it.

Let’s explore why your air conditioner might be making clicking noises and what you can do about it.

The AC is turning on and off too frequently. 

If your air conditioner turns on and off more frequently than usual, it could indicate that the unit is overloaded or that the thermostat is set too low. An overloaded AC unit often makes clicking noises as it tries to turn on. You can try raising the thermostat to see if that alleviates the problem. If not, you may need to have a professional look at your AC unit to see if it needs to be replaced or repaired.

You can avoid this issue by ensuring that your AC unit is the proper size for your home and having it serviced regularly.

Dirty filters

Another possible reason your air conditioner is making clicking noises is that the filters are dirty. When the filters are clogged, they can restrict airflow and cause the AC unit to work harder than it should. It can lead to all sorts of problems, including clicking noises.

Use an air compressor or vacuum to clean the filters. Wash out debris with water from a pressurized hose after soaking the filter in vinegar and warm water solution for complete cleaning. Check and clean your filters regularly to keep your AC unit running smoothly.

Capacitor problems

A capacitor is a small, cylindrical part that aids in the AC’s compressor turning on. The air conditioner may often switch on and off if the capacitor is damaged. Problems with the capacitor, the circuit breaker, the control board, or both may be to blame.

Turn off the power source at the breaker panel. Reach the capacitator and remove the air conditioner panel. Next, look for any form changes in the capacitor.

Check and keep in mind how the former capacitator’s wires were attached. Take out the old capacitor. The old capacitor’s wires should be removed and connected to the new one. To prevent any misunderstanding, work on one wire at a time.

Damaged compressor

The compressor is one of the most critical parts of the AC unit, so if it’s damaged, it can cause all sorts of problems. The compressor helps to circulate coolant throughout the AC unit, and when it’s not working correctly, the entire unit can suffer. If your AC unit is making clicking noises, it could indicate that the compressor is damaged and needs to be repaired or replaced.

Tighten the compressor’s bolts if they’re loose. If the compressor is damaged, you’ll need to have it repaired or replaced by a professional.

Fan blades issues

If there’s a problem with one of the electrical components inside your air conditioner, it can also cause a clicking noise. It is usually caused by a loose wire contacting another metal component inside the unit, which creates a sparking noise as electricity flows through it. To fix this problem, you’ll need to shut off power to the AC unit and locate, repair, or replace the damaged component.

Loose screws or bolts

Another possible reason your AC unit is making clicking noises is that there are loose screws or bolts inside the unit. It can happen over time as the unit vibrates, and it can cause all sorts of problems. To fix this, you’ll need to shut off power to the AC unit and locate and tighten any loose screws or bolts.


If your air conditioner is making clicking noises, it’s essential to have it checked out by a professional as soon as possible. While it may not be a severe problem, it could indicate an issue that needs to be fixed. Ignoring the problem could lead to further damage to your air conditioner or even result in a complete breakdown.
