Why It’s Important: Low refrigerant can result in poor cooling and, if left unchecked, could cause damage to your aircon’s compressor. Having it recharged by a professional ensures it works efficiently.

10. Age of the Aircon Unit

If your aircon is over 10 years old, it might not perform as efficiently as newer models. As aircons age, they lose their ability to cool effectively, even with regular maintenance.

What You Can Do:

• Consider replacing the unit if it’s over 10 years old and has frequent issues. Newer units are more energy-efficient and can provide better cooling.

Why It’s Important: Replacing an old aircon can lead to better energy savings and more reliable performance. Older units are also more likely to experience issues that are costly to repair.

Final Thoughts

If your aircon isn’t cooling properly, acting quickly before the problem worsens is essential. Whether it’s a dirty filter, a refrigerant leak, or a faulty compressor, these issues can all contribute to poor cooling performance. While some problems can be addressed through basic maintenance, others require professional attention.

If you notice any unusual noises or foul smells, or if your aircon isn’t performing efficiently, it’s best to call a professional to inspect and repair your unit. Regular maintenance and timely repairs will ensure that your aircon continues to provide cool, refreshing air, even during the hottest months.
