5 Common Air Conditioner Issues And How to Deal With Them

Picture this: It’s a scorching day, and you’re eagerly anticipating the refreshing blast of cool air from your trusty air conditioner. But alas! Instead of the blissful coolness you expected, you’re met with lukewarm gusts or, even worse, an eerie silence.

Fear not, for you’re not alone in this battle against aircon troubles! In the world of household woes, issues with your air conditioner are not uncommon, but they don’t need to be a cause for panic.

In this article, we will discuss some of the most common aircon problems and provide practical solutions to deal with them effectively.

1. Poor cooling performance

Poor cooling performance is one of the most common problems people have with their air conditioners.

If your air conditioner isn’t cooling the room as well as it used to, the issue might be a clogged or filthy air filter. A dirty filter restricts the airflow, reducing the cooling capacity of the unit.

To resolve this, clean or replace the filter regularly, preferably every 1-2 months.

2. Strange noises

Unusual noises such as squealing, grinding, or banging coming from your aircon can indicate various problems. Loose or damaged parts, worn-out belts, or debris inside the unit can be the culprits.

It is vital to address these issues promptly to prevent further damage. If you are unsure about the source of the noise, it would be best to consult a professional technician for a thorough inspection.

3. Leaking water

Water leaks around your aircon unit can be caused by a clogged drain line or a malfunctioning condensate pump. A clogged drain line prevents the condensed water from draining properly, leading to leaks. Check the drain line on a regular basis to ensure it is clear of any obstructions. If the problem persists, get expert assistance to diagnose and resolve it.

4. Foul odours

If your aircon emits unpleasant odours, it could be due to mould or mildew growth inside the unit or ductwork. Regular cleaning and maintenance can prevent this problem. Additionally, using air purifiers and ensuring proper ventilation in the room can help minimise odours.

5. Inadequate airflow

Insufficient airflow can result from a faulty fan or a blocked air duct. Inspect the fan for damage and clean the air ducts regularly to ensure optimal airflow. If the problem persists, consider contacting a technician to assess and fix the issue.


Regular maintenance and timely troubleshooting are key to ensuring your aircon operates efficiently and lasts longer. By addressing common issues promptly, you can enjoy a comfortable indoor environment throughout the year.
