8 Reasons Why Your Aircon is Not Cold and How To Fix It

An air conditioner’s failure to blow cool air is the worst nightmare of every homeowner in Singapore, especially when the temperature is skyrocketing like during summer. Unless you can identify the issue and have it addressed immediately, things will get uncomfortable and sticky at home. Do not prolong your agony: let’s talk about the top 8 reasons why your aircon is not cold and what you can do about it.

Reason #1 – Incorrect Thermostat Setting

The thermostat is usually the reason for an inefficient aircon. If it is set at a higher threshold, then it might not be actually turning on. If the thermostat, for instance, is set at 24 degrees Celsius and your aircon, at 28 degrees Celsius. Besides, it might not be blowing cool air if it is on the “Auto” mode instead of “On”.
Now you will need to do some inspection. First and foremost, make sure that the aircon is turned off and nothing in the breakers has tripped. Next, reset the thermostat and adjust the temperature to slightly lower than that of the house. For example, set it at 23 degrees Celsius if your home’s temperature is 27 degrees Celsius. Doing this enables you to notice a difference.
It will take a few minutes for you to feel cold air, so do not panic if you do not feel it right away. After waiting, position your hand above the vents to check for any cool air. A simple reset of the thermostat may be all you needed. If this doesn’t solve the problem, there could be something wrong with the internal wiring. You will need to consult an expert from SOServices in Singapore on this concern.

Reason #2 – Clogged Air Filter

A clogged air filter is another common reason why your air conditioner is not cooling the house. Some homeowners in Singapore think that the air filter does not contribute to the cooling capacity of the air conditioner, but it does. Without regular checking and replacing, the filter can become extremely clogged and unable to blow air into your home. It is recommended that you check your filter once a month and clean or replace it when necessary.

Reason #3 – Dirty Condenser Unit

The outdoor unit of your air conditioner is referred to as the condenser. A buildup of debris and dirt inside it could also be the reason why your air conditioner is working but not cooling. Your aircon needs to work harder in absorbing air and cooling it. A dirty condenser and a clogged filter will give you the same problem.
You can clean your condenser on your own but be careful not to break or bend anything. Use water and soap to wipe the dirt off gently. A garden hose with low pressure can also be used. You can minimize debris and dirt in the future by purchasing a weatherproof cover for your unit when it is not in use. It is also important to keep the surrounding area of the condenser free from branches, plants, and weeds.

Reason #4 – Underlying Mechanical Problems

Just like most things, every air conditioner is prone to normal wear and tear as time goes by. At some point in its lifespan, mechanical problems could arise and become potential reasons why your air conditioner is not blowing cold air but running. If your unit is often (or always) not functioning well, and the filter and thermostat are perfectly fine, you must contact SOServices right away to inspect the internal operations of the aircon.

Reason #5 – Refrigerant Leak Issue

Refrigerant is typically cycled between your indoor and outdoor AC units. You do not need to fill or replace it as it does not run out. However, when the refrigerant leaks, there will be not enough of it left to absorb heat well. This occurrence leads to a reduced supply of cool air.

How can you detect a refrigerant leak?

  • There is a hissing sound while the aircon is in use.
  • The air conditioning unit freezes up.
  • A buildup of ice on the aircon.
  • It will take so long to cool your house.

If you suspect or detect a refrigerant leak, immediately stop using the aircon and get in touch with SOServices in Singapore. Solving this problem calls for a highly trained professional.

Reason #6 – No Annual Maintenance

Annual maintenance of your air conditioner is necessary. Failure to have your unit maintained yearly may result in costly repairs and unexpected breakdowns. It could also be the reason why your air conditioner is running but not lowering the temperature on the hottest days of the year.

Reason #7 – Incorrect Aircon Size

An aircon that is either too small or too big will cause a lot of problems, including no cool air. This issue will unfortunately never end until you replace the unit. Our professionals at SOServices can help you choose the right size of AC in Singapore the first time. But if you cannot replace your unit, for now, let us set up regular servicing appointments.

Reason #8 – Ductwork Leak Problem

A leak in the ductwork could be the reason why your AC is not cooling. It is slightly difficult to diagnose and can cost you money and cool air. When there is a leak in the ductwork, the cool air will be filtered out into your walls before reaching the vents.

It is frustrating when your air conditioning unit is not capable to do the only thing that it is intended to do – to give cool air – especially when you live in a tropical country like Singapore.
