In Singapore, the climate is mostly tropical and therefore an aircon unit is a must in every house and commercial establishment. Not only does an air conditioning unit help people to sleep more soundly, it also provides a more conducive working environment by giving added comfort and convenience. However, on many occasions, the aircon unit might stop blowing cool air in residences and workplaces in Singapore. In this article, we will be discussing several possible reasons why an aircon is not blowing cool air and a couple of helpful tips to fix it.
1. Air Filter Clogging
The filter helps to trap airborne particles traveling through the ductwork before they can damage the aircon unit significantly. The filter can get clogged and restrict the flow of air if you don’t change the filter for quite some time. If so, there is a chance for the evaporator coil to freeze and it will not be able to cool the air anymore.
2. Dirty Condenser Coils
The condenser coil might become dirty and full of debris over time. It is important to wash the condenser so as to dissipate the heat outside. If the coils become quite dirty, it will not be possible for the aircon unit to cool the room anymore.
3. Broken Compressor
The compressor of the air conditioning unit circulates refrigerant between the outside and inside units. The indoor units cannot blow cold air if the compressor starts malfunctioning. Thus, it is often necessary to replace a broken and faulty compressor.
4. Defective Thermostat
A thermostat aids in detecting alterations in temperature. A malfunctioning or broken thermostat can be one significant reason why your house or room is not becoming cold. Therefore, it is of prime importance to inspect it from time to time to make sure that it is working properly.
5. Small Air Conditioner, Large Spaces
Always purchase an aircon that will have the capacity to serve your residence or workplace’s space requirement. If your house or room is small, it would be wise to opt for smaller-sized aircon machines. The same applies to larger air conditioning units for bigger spaces. There is no use buying a small unit for a big room since it will overwhelm the aircon’s performance capacity and prevent it from functioning properly. On the other hand, a large unit for small rooms is not ideal since you will suffer from overcooling and a higher electricity bill. We have consolidated a checklist for your perusal to purchase the right type of aircon in this article.
One way of knowing when you are purchasing the right type of aircon for your space is knowing the aircon's BTU. Read more about BTU here.
6. Leaked Refrigerant
Leaked refrigerant can also be one of the reasons why an aircon is not supplying cold air. This problem is quite common at present with the residents of Singapore. If the problem persists, you will get a warning message to replace the refrigerant in order to continue enjoying cool air. In most cases, replacing the component will be a better idea than trying to repair it. This will also help in fixing the overall aircon machine effectively.
7. Dirty Evaporator
The evaporator is a key component of the aircon. It helps to make sure that the device is working properly and makes the house cold as well. The aircon will not work efficiently without a clean evaporator and will be unable to keep you comfortable during the sweltering hot summer season. Therefore, if the question “why is the aircon not cold?” starts creeping up in your mind, it’s always a good idea to check the evaporator at regular intervals. Make it a point to wash it regularly to maintain its functionality. The cleaning can be done at an interval of 6 months to once a year, according to the situation.
8. Blocked Condenser
The condenser is one of the most essential components of an aircon that helps to make sure that your residence or workplace is cold. It is the condenser that is accountable for providing cold air within your room, and if it gets clogged, you will start feeling uncomfortable during summer. If this component accumulates dirt and grime over time, it won’t allow cold air to enter the room as needed. This will minimize the efficiency of the unit and you will end up getting frustrated in the long run. To get the best results, make sure to wash the condenser a minimum of once a month.
1. Make Sure The Thermostat Is Set To Cool
On most occasions, you do need to exert yourself much to fix an aircon that is not blowing cool air. Prior to calling the technicians, make sure that it is set to “cool,” and also that the temperature of the room is low enough to switch on the unit.
2. Inspect Circuit Breaker Box
If the problem of your aircon is not because of the thermostat, then you ought to verify the circuit breaker box. Most air conditioning units come with two parts — the indoor unit, and the outdoor unit. If the outdoor device isn’t powered, the indoor unit will not be able to supply you with cold air. Try resetting any tripped circuit breaker and wait for some time to check whether the problem occurs again. If the problem does not go away, it's time for you to seek the help of a professional expert.
3. Clean Dirty Aircon Filters
Dirty aircon filters will make the device work harder plus less effectively. As a result, there is the possibility for your electricity bills to go up and you won’t get the cold air you desire. Make it a point to wash the filters at least once every month.
4. Check If There’s Ice Build-Up In The Aircon
Ice build-up is another common issue that air conditioning units tend to encounter from time to time. This will result in low cooling performance in the long run. If you’re experiencing this, try turning off the unit and raising the cover to verify whether there is any ice build-up. This usually takes place if the fan blower belt gets damaged over time.
With all these common reasons that deprive an aircon of supplying cold air, it is important to always set a regular maintenance schedule for your unit at least once a year. This includes standard aircon repair, cleaning and replacements to keep your unit in great shape. However, to get optimum results and a higher total lifespan for your unit, it’s recommended to perform regular checks every month.
