How To Repair Aircon That Is Not Cooling? The air conditioning blowing out hot air in hot can be frustrating. Remember, in Singapore, the weather a well-functioning air conditioner is integral for every home or office.

In some instances, the aircon unit may malfunction and stop blowing cool air in your home and office in Singapore. The article is a comprehensive guide on the leading reasons why your unit is not cooling your residence and how to repair the aircon.
Top Reasons why your AC is not Cooling and Best Ways to Repair Aircon:
1. The Air Filters are Dirty

One of the most common reasons your AC unit is not cooling is a dirty filter. Dust and debris can accumulate on your air filters, thus interfering with the proper functioning of the thermostat. Dirt may clog the filters and interfere with the passage of warm and cool air coming from the ducts. In other instances, it can cause your evaporator coil to freeze, thus preventing adequate passage of cool air from the ducts.
Some of the reasons that can be contributing to dirty air filters include:
- Your AC has one-inch pleated filters-these filters are very susceptible to the accumulation of dirt as they are designed to trap all airborne contaminants.
- AC is running on the wrong setting-where there is an incorrect setting, air will continuously flow on the air filters causing them to accumulate dirt very fast.
- A leak in the air ducts-it can cause your air filter to accumulate dirt very fast.
- Your residence has pets-they can produce fur and contaminants that will eventually accumulate on the air filters.
How to Fix the Issue
Since dirty or clogged air filters will interfere with your AC unit’s process of cooling your space, it is integral to ensure you regularly clean them. You can ensure that you clean the air filters every month. If they are severely damaged, you can replace the air filters and repair the aircon.
2. Thermostat Settings are Incorrect

A thermostat is very integral in detecting any alterations in the internal temperature. If the thermostat settings are not set correctly, it will not adequately sense the temperature changes. Also, a broken malfunctioning thermostat can interfere with how your AC is working.
How to Fix the Issue
The first step is to check the settings of your thermostat. Ensure that the settings are on ’Auto’’ mode so that your thermostat can automatically detect any rise or fall in temperature in your home. If the thermostat is defective or broken, consider replacing it with a new one.
3. The Condenser Coils are Dirty

Your condenser coils might accumulate dirt or debris interfering with the normal functioning of the AC unit. Remember that your condenser works to convert hot air into cool air. If it is clogged, it will interfere with the colling of the AC unit. Debris will even block the process of heat transfer.
How to Fix the Issue
Ensure that you regularly clean the condenser by carefully removing any debris or dirt clogging it. You can also ensure that your AC unit is regularly inspected by a professional who can repair the aircon early enough.
4. Defective Motors

The motors of the AC unit can either be broken or faulty. The AC motors can fail either due to improper maintenance or it is very old. If the motor is not working correctly, it will block your AC unit from dissipating heat, thus causing problems with your unit’s heating and cooling process.
How to Fix the Issue
Ensure that you hire a professional who will inspect the AC motor and advice you of the most appropriate step. They can decide to either repair the aircon motor or replace it.
5. Broken Compressor

The compressor of the AC unit circulates the refrigerant and indoor units. If you have a broken compressor, the indoors cannot blow cold air. Thus a damaged compressor will interfere with the process of cooling air.
How to Fix the Issue
A damaged or faulty compressor needs replacement. It is integral to ensure you hire a professional who will accurately repair the aircon.
6. A Low Refrigerant Level

A refrigerant is a very vital fluid in the AC unit. It helps to absorb heat from the internal environment. If the levels of this fluid are too low, it will interfere with the AC cooling process. The most probable cause of low refrigerant level is leakage.
How to Fix the Issue
It is possible to determine the issue of a low refrigerant level. Some of the common notable issues are bubbling or hissing sounds and ice accumulation on your outside unit. If you identify any of these issues, ensure you consult an expert for a professional fix.
7. Your Air Conditioner is Small

When purchasing an air conditioner unit, it is always imperative to consider the size of your space. The unit you buy should have the required capacity to cool the room. If your home or office is small, it is recommended that you purchase a small-sized unit. On the other hand, if your home or office is enormous, ensure you buy a larger-sized machine with a higher capacity.
How to Fix the Issue
When purchasing the AC unit, it is essential to check the British Thermal Unit (BTU). BTU is simply a measurement of the amount of energy your system uses to cool your space within an hour. It is a fundamental metric to help you select the best unit you require for your home or office, depending on the size.
8. Dirty Evaporator

The evaporator is an integral part of the aircon. It ensures that your unit is working well and provides your house is cool. If the evaporator is not working well, your system will not efficiently cool your space.
How to Fix the Issue
Ensure that you regularly clean your evaporator at least twice per month. If the evaporator is defective, call experts to repair the aircon professionally.
How To Repair Aircon That Is Not Cooling? – Conclusion

The above reasons can cause your aircon not to cool adequately, which can be pretty frustrating. To avoid these problems, ensure that you schedule regular AC unit maintenance once per year. Also, ensure that you repair the aircon as soon as you detect a problem.
