These noises could indicate various issues such as a faulty capacitor, a malfunctioning thermostat, or a damaged compressor.

Ignoring these sounds can result in a complete breakdown of your system and lead to expensive repairs. Therefore, it is crucial to address the problem by contacting a professional hvac technician who can diagnose and fix the issue. In this article, we will discuss the possible causes of ac clicking noises and provide some basic troubleshooting tips.

Common Causes Of Clicking In Ac Units

No one wants to hear clicking sounds coming from their air conditioning unit, especially on a hot summer day. These sounds can be a sign of underlying issues that could escalate if not addressed immediately. In this section, we will discuss the most common causes of clicking in ac units and the signs that indicate a problem.

Malfunctioning Capacitor Or Electrical Relay

If the clicking is coming from the outdoor unit, a faulty capacitor or electrical relay could be the culprit. The capacitor is responsible for starting the ac’s compressor, while the relay helps the unit switch between different modes. Signs of a malfunctioning capacitor or electrical relay include:

• The ac unit won’t turn on or starts, then abruptly turns off
• The ac unit hums or makes other unusual noises
• The ac unit shuts down without completing a cycle.
• The ac unit struggles to start

Clogged Air Filter

A clogged air filter can also produce clicking sounds in your ac unit. Air filters trap dirt, dust, and other debris and prevent them from circulating around your home. However, they become clogged over time, and this can affect the unit’s performance.

Signs of a clogged air filter include:

• The air conditioner takes longer to cool the room
• The air conditioner emits stale or musty odours
• The air conditioner struggles to circulate air
• The air conditioner produces a weak airflow

Low Refrigerant Levels

Refrigerant is a liquid that flows through your ac unit’s coils and removes heat from the air. However, low refrigerant levels can cause the ac unit to click. Signs of low refrigerant levels are:

• The ac unit takes longer to cool the air
• The ac unit produces warm air instead of cool air
• The ac unit struggles to reach the set temperature
• The ac unit produces hissing or bubbling noises

Damaged Thermostat

A damaged thermostat can also cause clicking sounds in your ac unit. The thermostat regulates the ac’s temperature based on your home’s temperature set point. If it becomes faulty, it can send the wrong signals to the ac unit, causing it to malfunction.

Signs of a faulty thermostat include:

• The ac unit turns on and off frequently
• The ac unit produces uneven cooling
• The ac unit fails to maintain a stable temperature
• The ac unit turns off entirely

Now that you know the common causes of clicking in ac units, you can identify issues early and call a professional to fix them. Remember to schedule regular maintenance to prevent future problems.
