Why Is Your Aircon Noisy?

A noisy air conditioner is very annoying and alarming. Strange sounds should not be ignored for fear of expensive repairs. Understanding what is causing it will help you correct it early. Let’s examine common causes of your air conditioner making noise and how to fix them.

Loose Parts Issue

The aircon parts can loosen over time due to constant use. Rattling or buzzing sounds due to vibration of screws, fan blades, or panels. First, check for loose screws if you hear these noises. In many cases, you should be able to tighten them to fix the problem. A technician from https://www.socool.sg/ may have to look internally to try and find the source of the sound if the sound is not fixed when the computer is reassembled.

Fan Problems

The aircon has a fan inside it that moves air efficiently. However, if it bends or gets damaged or blocked, it may start making clicking or scraping noises. Also, the fan blades can develop dirt buildup and cause imbalance. However, having the habit of regular cleaning can prevent this issue. If the fan is ruined, we may need to replace it to avoid further damage.

Dirty or Clogged Filters

Blocked airflow results from dirty filters, requiring your air conditioner to work harder. This can cause whistling or wheezing when you breathe. Clogged filters reduce the air conditioner’s efficiency and place an unnecessary strain on energy use. As the air conditioner filter gets dirty, it needs cleaning or replacing every few months to run efficiently and quietly.

Refrigerant Issues

The cooling fluid inside your air conditioner is called refrigerant. If it leaks, you may hear a hissing or bubbling noise. Reduced refrigerant levels will diminish the system’s cooling performance and strain it. Referring to professional help like https://www.socool.sg/why-is-your-aircon-noisy/ for RF leaks is essential, as they require special tools and safety practices.

Compressor Malfunctions

Your aircon’s heart is the compressor. The air is cooled with the refrigerant being pumped. However, if the latter fails or fails otherwise, you will likely hear banging, humming, or clanking sounds. The compressor is a failure-prone component, and when the compressor fails, it can lead to either inefficient cooling or a complete breakdown. If you have a problem, you should call a technician.

Motor and Belt Wear

Wear and tear will cause your air conditioner’s belt-driven motor to squeal or screech. Belts stretch or crack over time and reduce their efficiency. Regular maintenance prevents sudden failures. Worn-out belts can be replaced, restoring smooth, quiet operation.

Ice Buildup Problem

If ice forms inside the unit, dropping or cracking sounds will occur. This happens when airflow is reduced or when the refrigerant levels are low. Turning off the air conditioner and temporarily allowing the ice to melt temporarily gives some relief. However, to permanently repair the issue, you must also check for underlying causes, such as a clogged filter or refrigerant leak.

Electrical Issues

Buzzing or clicking means an electrical fault. The cause can be loose wiring, faulty capacitors, or failing relays. If you hear a hissing sound or a burning smell, turn off the unit right away. Electrical problems can be dangerous and only adequately handled by a professional.

External Obstructions

Objects stuck in the outdoor unit can cause noise. The fan traps leaves, twigs, or other small debris, producing rattling or clicking noises. The outdoor unit can regularly check and clear these issues.

Installation Mistakes

Your air conditioner may have been installed improperly, causing it to vibrate or make unusual sounds. Continuous rattling may occur if the parts are poorly mounted, not properly insulated, or not aligned. A professional inspection can correct any installation errors when operating a quieter machine.

When to Call a Technician

Tightening screws or cleaning some noises is just what it takes. More often, persistent or loud noises are indicative of more significant problems. Any banging, screeching, or hissing sounds should prompt you to call a technician. Repairing early can save you from significant damage and prolong the life of your aircon.
