Considering Singapore’s hot climate, having a functioning air conditioner is almost necessary for indoor comfort. However, it can be frustrating when air conditioning fails to blow cool air. Knowledge of the common causes and remedies for this problem can prevent you from experiencing discomfort and the need for costly repairs.
Air Filter Getting Clogged Up
Dirty air filters are one of the most recurrent factors that prevent an air conditioning unit from blowing cold air through. Closed loops such as dust and dirt particles will gradually collect, hence diminishing cooler performance. Here in Singapore, the filters tend to get blocked fast because of the heightened use of aircon. If broken or dirty air conditioner/heater filters are replaced or cleaned, normal fresh air flow and cooling are restored. Cleaning of air filters is recommended around this time of the year, approximately four times a year.
Refrigerant Management
The refrigerant is what freezes the air inside the air conditioning compressor. If the aircon is now blowing cold air, some refrigerant leaks could affect the efficiency of the aircon. Besides the room not receiving proper cooling, periods to chill the air conditioner room would be alarming. For this sweating cooling, an expert technician is the only person able to solve refrigerant leakage problems and refill the refrigerant. Frequent aircon service in Singapore like https://www.airconservicing.org/aircon-not-cold/ enables possible anime difficulties from refrigerants to be detected initially and avoided.
Dirty Condenser Coils
The function of the condenser coils is to expel the heat in the air, which allows the air conditioner to produce cool air. However, they may be dirty or have dust, which makes them ineffective and results in poor cooling. Therefore, in Singapore, it is even more important to keep the condenser cleaner as the degree of dirt accumulation grows faster. An external unit must be cleaned regularly to enhance cooling efficiency.
Evaporator Coils Froze
Once the evaporator coils get frozen, the air conditioning cools the air efficiently, much to the comfort of the occupants, thus allowing the aircon vents to operate in hot air. This usually occurs due to dirty air filters and low levels of refrigerants. Where ice is visible on the coils, switch off the air conditioning machine for some time to allow these coils to defrost. Fixing air filters and checking the level of refrigerants should return the situation to regular exposure. Further, obtain assistance like from https://www.airconservicing.org/ if the issue remains unsolved.
Faulty Compressor
The function of the operated compressor is to charge refrigerant and circulate it heretofore to cool the surrounding space. An air conditioning system that does not blow cold air usually damages the compressor. This may be the case due to usage, some electrical fault, or feasible overheating alternatives. Unfortunately, the cost of repairing and replacing the head unit is the defect case. If the temperature of your aircon is not low and you start suspecting the compressor, then a technician should be called for troubleshooting and rectification.
Setting the Thermostat Incorrectly
Sometimes, the air conditioner may not be cold due to incorrectly setting the thermostat’s temperature. Ensure that the thermostat has been switched to the “cool” position and that the current temperature is above the desired temperature. If it is somehow not operating, it will need changing to resolve the issue. Proper thermostat management can also save one from cooling problems.
Leaky Air Conditioning Ducts
With a central air conditioning system, leaky air conditioning ducts will space out the required cooling. When cuts are made and only dry, cool air escapes before supply to the rooms, the air conditioner has less power. This not only diminishes the cooling but also raises operating costs. The problem can be remedied by identifying and fixing the leaks in the air ducts.
Outdoor Unit Blockage
The outdoor unit is critical in releasing the heat accumulated in the aircon system. This apparatus cools the house by dispersing heat, and if impeded by obstructions such as erosive materials and leaves, it fails to do its work adequately. In Singapore, outdoor units are often dust-covered and exposed to the weather. Routine maintenance by removing obstructed materials from around the outdoor unit will enable efficient cooling.
