In Singapore, most of the homes have an air conditioner. Sometimes your room will not get enough cooling with your aircon so at that time you might be quick to contact a professional Aircon service company to solve the cooling issue.

Reasons of Aircon Not Cooling

Dirty Air Filter

It is important to change the aircon filter on a regular basis because a dirty filter will stop the free flow of air and could end up preventing the AC from cooling as much as it should.

Be sure that you change or aircon clean the air filter on a monthly basis.

Dirty AC Compressor

When the air con compressor becomes dirty or blocked, it cannot cool the room properly. So we must properly clean the compressor so it will keep the heat outside.

It may be necessary to trim the area to keep the blockage from occurring. If it doesn’t fix the problem, contact a professional aircon chemical wash cleaning company.

Fault or Defective AC Compressor

In Some cases, the Ac compressor might be damaged so aircon might not cool your room enough. Although this is a relatively rare situation, it may be possible for a defective compressor to be causing your low air-con temperatures.

A Technician can check your aircon compressor and if necessary, they can replace it with a new one.

Damage Ductwork 

There may be times when the aircon duct work becomes damaged and if that is the case, the cool air  will not properly occur in your rooms so check with the nearest aircon company.In rare cases, the aircon ducts may also get blocked.

Small Aircon with large size rooms

Weak Batteries

Before you contact a professional, make sure that you checked the batteries in the thermostat. This is something that is often overlooked but it can certainly make a difference in how cold your aircon is blowing. It may seem like it is operating fine but without the batteries backing things up, you would end up quite warm.

Low Refrigerant Cause Aircon Not Blowing Cold Air

It may be possible that your aircon unit is low on refrigerant. A loss of refrigerant can certainly result in the Aircon not blowing cold air and it may even signal the fact that there is a leak.

A professional aircon repair service can come in and assess the situation. They can stop the leak from occurring and put some more gases in the system to get your air blowing cold again.

Drainage Pipe

The moisture that is built up within the unit drains out through a pipe. If the drainage pipe is blocked, the aircon service unit needs to work harder in order to make the air conditioner that is blowing through your home.

Fan Not Working

It may be possible that the aircon fan wheel is no longer operating properly. You could check this yourself to a certain extent by going to the indoor unit and seeing if the fan is buzzing or if it is actually operating.

A long screwdriver can be used for this but you want to be cautious that you don’t damage the fan while testing its aircon general service.

Frozen Air Con Unit

One other possibility is that the unit has frozen on the outside. This is something that can be determined by a visuals inspection. If the unit is frozen, turn it off until it thaws fully and then you can turn it back on to cool the home.

More than likely, you will want to contact a professional to address the situation so that it doesn’t continue to happen over and over again.
