Common Issues with Aircon Units and How to Fix Them

Air conditioning is essential for maintaining a comfortable working environment, especially during hot weather. However, even the most reliable systems can develop problems over time. Recognising common aircon issues early can help you address them quickly, whether it’s a simple fix or something that requires professional attention. Ignoring small issues can lead to bigger, more expensive problems down the line.

In this blog, we’ll explore some of the most common air conditioning problems, from low airflow to overheating units, and offer practical advice on how to solve them, saving you both time and money.

Low Airflow Coming from the Unit

One of the most noticeable signs of a problem is weak airflow. This usually occurs because the filter has collected dust and other particles. The more clogged the filter becomes, the harder it is for air to pass through, reducing performance.

How to fix it: In many cases, you can resolve this yourself by checking and cleaning or replacing the filter. Most manufacturers recommend cleaning every one to three months. If the issue persists, it may point to a more serious mechanical fault, and a qualified air conditioning contractor should investigate.

Poor Cooling When in Use

When airflow is blocked, your air conditioner struggles to distribute cool air evenly, which can create hot and cold spots in the room. This makes it difficult for the set temperature to reach all corners.

How to fix it: Start with the filter, as cleaning it can often restore cooling efficiency. If the problem continues, it could be a refrigerant leak or a damaged fan motor. These are not DIY fixes and require expert diagnosis to prevent long-term damage.

Musty Smell

A musty or unpleasant smell coming from your air conditioner often indicates a build-up of dust, mould, or damp particles on the filter. When this is left unchecked, it can have a negative effect on air quality.

How to fix it: Cleaning or replacing the filter usually removes the odour. If the smell lingers, there could be mould growth inside the ducts or unit itself, which should be handled by an experienced air conditioning contractor.

Overheating Unit

When a clogged filter forces the air conditioner to work harder than it should, the unit can overheat. This increases energy use and can eventually cause a breakdown.

How to fix it: Replace or clean the filter promptly. If overheating continues, turn off the system and contact a professional before further damage occurs.
