Well look no further, as we will be addressing the top few most frequently asked questions when it comes to the issues faced with an aircon unit. Here are the explanations to some of your commonly asked questions:


How often do I need to service my aircon unit?

We are sure that you have heard our constant nagging and reminders, telling you the importance of servicing your aircon unit. But, how often?

With the increasing need to use aircon units in hot and humid Singapore, it would certainly be wise to have your aircon unit serviced once every 4 months. Here are some of the benefits to servicing your aircon unit regularly.

Why is my aircon unit leaking?

One of the most common reasons is that the drain hole in your aircon unit may be clogged. The hole may be clogged due to excess accumulation of dirt or mold. When the water is unable to exit the aircon unit through the drain line it results in very minimal to no water flow, resulting in the reverse flow of water leak back into your home. Therefore, do check the drain line for any signs of blockage that is causing the leak. Find out in greater detail on why your aircon unit is leaking here.

Is there a way to reduce my aircon unit bills?

Consider purchasing aircon units with Energy Efficiency Labels. The greater the number of ticks, the greater cost-savings it will bring you in the future. Aircon units with 5 ticks on their energy level can possibly save you an estimated $100 more than aircon units with 4 energy level ticks.

Set up a timer on your aircon unit remote that turns off your aircon unit. In comparison to the full 8 hours when you are asleep that the aircon unit runs, it is perhaps wiser to set a timer that turns off your aircon unit 2 hours before you wake up. Fret not, the temperature of the room will stay relatively the same. This method will definitely translate to cost-savings in the long-run. By calculation, by reducing usage on aircon for 2 hours everyday, you will be reducing your aircon usage by around 60 hours on a monthly basis.

Not to forget, the aircon bills saved can contribute towards aircon servicing is required every 4 months.

Can I DIY clean my aircon unit?

Yes, absolutely. You should clean the aircon unit filter on a bi-weekly basis and it is recommended to change it once every 2-3 months to ensure that air-flow is clear and unobstructed. This ensures that the aircon unit operates optimally and the room remains cool for longer periods of time. Remove the casing surrounding the aircon unit filter and then take out the filter. You can wash the filter under water or vacuum the filter to get rid of the dirt.

An easy method to DIY clean your aircon unit is to use a vacuum cleaner. A vacuum cleaner can be used to clean external surfaces and can reach some of the internal parts of the aircon unit. Hold the vacuum under low power over the exterior of the aircon unit into the ducts, pipes and fans.

Do take note that DIY aircon unit regular maintenance is important however more has to be done, such as aircon unit chemical wash, if you want to keep your aircon unit functioning optimally.

Why is the aircon unit not as cold anymore?

Here are some possible reasons why your aircon unit is not cooling down the room as efficiently as before:

Faulty Thermostat

If your aircon unit is connected to a thermostat, do take a quick check to see if the temperature displayed on the thermostat is correct. It is a potential cause of your aircon unit not being cold enough.

Blocked Condenser

A condenser is one of the most vital aircon unit parts in ensuring that your aircon unit pushes out cold air into your room. When it gets blocked, cold air is less able to enter the room. With that, you will have to clean your aircon unit condenser regularly.

Aircon Parts Malfunctioning

Take for example: a broken compressor or a malfunctioning refrigerant that inhibits the indoor unit of the aircon unit from blowing out cool air.
