Why Is My Aircon Blowing Warm Air?

Why Is My Aircon Blowing Warm Air? Having an air conditioner system in every household is quite common in Singapore. Due to the climatic condition there, aircon is used quite frequently and throughout the year.

Hence, facing some of the problems with your air conditioner system is also quite common. Among all those issues, one of the most frequently faced issues is – aircon warm air blowing.

This issue can be really problematic as it can make you sweat more than usual if the air conditioner is blowing our warm air into the house. But you are not alone. There are many people who face this same problem with their aircon. Read on to know why people face this issue quite often.

Why aircon is blowing warm air?

It is incredibly frustrating, especially on an extremely hot and humid day in Singapore when your air conditioner is blowing warm air. AC units are supposed to cool down your home. Instead, when it is blowing warm air, there might be an issue with it. What is it? Here are some of the reasons why your aircon might be blowing warm air instead of cool air:

The issue with the thermostat settings:

Before you go in-depth with this issue, check the thermostat once. Often wrong setting of the thermostat or an issue with the thermostat can cause this problem. Double-check whether or not the thermostat mentions ‘cool’ or ‘cooling’ instead of ‘heat’.

Sometimes the thermostat can get tampered with or changed due to accidental touches. Also, make sure that the thermostat is set to ‘Auto’. If the problem is with the thermostat, this step will solve your issue.

Clogged condenser coil and filters:

When the filter is clogged or the condenser coil in the outdoor unit is clogged, the air conditioner unit cannot work efficiently to eliminate the indoor heat. The debris and dust can cause this clogging and it will cause trouble for the system to remove the heat completely.

Due to this, the aircon will fail to cool your home as the aircon fan will blow back the heat into your space again. So, this might be causing the aircon warm air blowing issue.

Outdoor unit power issue:

Another reason why your air conditioner will blow warm air is the power issue with the outdoor unit. When the outdoor unit has lost power but the indoor one is still working and functioning, the warm air cannot escape. This results in warm air blowing out through the indoor AC unit.

This power issue can be the result of a circuit failure or fuse issue. You can call for a professional aircon technician to help you solve the issue.

Low level of refrigerant:

The next reason why you can face aircon is blowing warm air in the lower level of the refrigerant. The refrigerant gas can escape if there is any leak and this will result in lowering the refrigerant. With a low level of refrigerant, your aircon unit can struggle to keep your room cooler.

In some cause, ice can form on them which restricts the heat to pass too. This will likely cause warm air to blow back into your room.

Return vent is blocked or closed:

Another most common reason behind the warm air blowing out from the air conditioner is the blocked or closed return vent. When the vent is closed or blocked, the air cannot flow freely and this can make the warm air trapped inside the air conditioner unit.

Being unable to return or eliminate the warm air, the aircon will start to blow the warm air into your house causing the temperature to rise instead of cooling it down.
