(Last Updated On: January 24, 2021)

Nothing is more uncomfortable more than coming back home from a long day of work only to find your aircon is not blowing cold air. This can be distressing, especially when you do not know how to solve it. The great news is that the issue may not be as complicated or costly to handle as you might have thought. If you do not have any idea about what to do, hiring expert air conditioning contractors is your best option. They will not only help you by determining the cause and solution for your air conditioning issues, they can also other types of services if needed such as aircon repair, aircon installation, and chemical overhaul.

 

With that being said, here are tips on how to troubleshoot an aircon that is not blowing cold air.

 

Check if Your Air Filters Are Clogged

Air filters are designed to trap airborne particles moving via the ductwork before the aircon cooling system gets disrupted. Sometimes, filters can get blocked and restrain the steady flow of air, and in such instance, your air conditioning system will not blow cold air. Therefore, check your aircon filter. If the aircon does not cool and you ascertain it is clogged, replace it. Blocked air filters can lead to a frozen evaporator coil, making it nearly impossible to cool the air. Therefore, it is always important to keep your air filters clean.

 

Check if Your Aircon Vents Are Closed or Blocked

Sometimes air vents in the house can get blocked by furniture, toys, and even drapes. Blockage to airflow prompts your aircon unit to work more, increasing the need for system repair.

Poor airflow also causes blower motor problems, frozen evaporator coils, or leaking water, among other defects.

To troubleshoot closed or blocked aircon vents, move around the house and have a close look at all the return and supply vents. Often, it is assumed that shutting vents in rooms rarely used cuts down costs. On the contrary, it destabilizes air pressure in the house and brings about additional malfunctioning problems.

 

Check If Your Aircon Compressor is Blocked

Aircon compressor is the engine of an air conditioning unit, which is liable for keeping your house cool. Therefore, an aircon that is not cooling can be a result of a blocked or faulty compressor. A compressor is simply a motor that squeezes the refrigerant and moves it via the evaporated fan coils and condenser coils. If the compressor becomes defective due to blockage, the cooling cycle will not start, and the air conditioning unit will not blow cold air.

 

Check If Your Aircon Switches Are Shut Off

Your aircon system contains switches to the indoor and outdoor aircon parts. Ensure the switches are turned on and not off. Additionally, some units may come with a water safety button to stop water leakage if the aircon gets blocked. To resolve the situation, clear the drain.

 

Check If Your Circuit Breaker Has Tripped

The significant power surges come from within your house. Lighting and external power grid problems sometimes blast power into your household, but in most cases, power surges occur due to large appliances. For example, aircon can cause a power increase when turned on. Therefore, an electrical defect can make your aircon unit stop working.

 

Spot the primary electrical panel for your home and search for circuit breakers. Look for “Aircon” or “Air Conditioner” if your panel is clearly labeled. If it is disconnected, reconnect and turn the breaker into the “ON” state and see if your aircon works again. If it works, then your circuit breaker had been tripped. However, if the problem persists that might be an aircon emergency, contact a professional.

 

Conclusion

Even though aircon troubleshooting can allow your aircon system to operate smoothly, aircon problems can be stopped before they start with a routine maintenance plan. Contact air conditioning professionals like DW Aircon to conduct a yearly or a quarterly checkup on your aircon. DW Aircon Servicing Singapore also provides different types of aircon services.
