Regular maintenance of the air filter is essential for your unit’s performance. Depending on your usage, it’s a good idea to clean or replace the filter every 3 to 6 months.

Clean the Coils

Aircons have two main sets of coils: the evaporator coils and the condenser coils. The evaporator coils absorb heat from the air, while the condenser coils expel that heat. If these coils become dirty or covered in dust, it can reduce your aircon’s cooling efficiency. After a busy holiday season, checking the coils and cleaning them if necessary is essential.

The evaporator coils are usually located inside the aircon unit, while the condenser coils are typically outside. Turn off the power to the unit before attempting to clean the coils. Use a soft brush or coil cleaner to remove dirt and dust from the coils gently. You can also use a coil cleaner spray for more stubborn grime if necessary.

Cleaning the coils ensures that the aircon can absorb and expel heat effectively, keeping your home cool. Make sure the coils are completely dry before turning the aircon back on.

Check for Refrigerant Leaks

If your aircon is still blowing warm air after cleaning the filter and adjusting the thermostat, the problem may be a refrigerant leak. Refrigerant is essential for cooling the air, and without it, your air conditioner cannot function properly. A refrigerant leak can occur due to wear and tear or improper installation.

To check for a leak, inspect the pipes and connections for any visible signs of moisture or oily residue. If you notice ice buildup around the coils or a hissing sound coming from the unit, these are also signs of a refrigerant leak.

Since refrigerant is a hazardous substance, it’s important to call a licensed professional to handle this issue. A technician can repair the leak, refill the refrigerant, and check for any other underlying issues.

Check the Circuit Breaker

If your aircon isn’t turning on after the festive season, it may be due to a tripped circuit breaker. Electrical issues are common after periods of high usage or after the unit has been off for an extended period. To check for this, head to your home’s electrical panel and look for the circuit breaker that powers the aircon. If the breaker is tripped, switch it back on.

If the breaker trips again shortly after resetting it, there could be a serious electrical issue with the aircon that requires professional assistance. A tripped breaker can indicate wiring problems or an issue with the aircon’s electrical components.

Perform Regular Maintenance

The best way to ensure your aircon continues running smoothly throughout the year is by scheduling regular maintenance. Preventive maintenance can catch potential issues before they become serious problems, and it can also improve the unit’s efficiency and lifespan.

You can clean the filters, clear the drain line, and check the thermostat yourself, but it’s a good idea to have a professional technician inspect your aircon at least once a year. During this inspection, the technician will clean the internal components, check the refrigerant levels, and ensure the aircon is running at its best.

Final Thoughts

Air conditioners are essential for keeping your home comfortable in Singapore’s hot and humid climate. After the festive season, it’s important to ensure your aircon is still in good working condition.
