9 Reasons Why Your Split Air Conditioner Is Not Cooling

In the hot summer weather, the pressure on air conditioners, whether split or window, can increase in order to provide cool air to cool rooms.

However, air conditioners may require periodic maintenance because most problems and malfunctions are associated with them. One of the most prominent of these problems is that the air conditioner does not cool, and this may result from many different reasons. In this article, we will discuss in detail the reasons why a split air conditioner does not cool.

Reasons why the split air conditioner does not work

Air conditioners not working or not cooling are among the worst malfunctions that can occur to air conditioners. This happens for many reasons, the most important of which we will mention below:

1. Electrical faults or poor air conditioning adjustment

Before starting, it is important to check for any faults in the various air conditioner parts and to ensure that the air conditioner is connected to the electricity and that all its connections are properly connected.

If the air conditioner is plugged in and not working, you can make sure that the device is set to the desired temperature.
Because sometimes we forget that the unit was set to a hot setting instead of a cold one, or the kids in the house were playing and the air conditioner was changed to a heating setting.

2. Outside temperatures

The recent period has witnessed a significant rise in temperatures, which was unusual. This is considered one of the basic things that affect the efficiency and operation of air conditioners because:

In some high temperatures, the air conditioner cannot handle it because it is unable to tolerate it.
This often results in malfunctions in parts of the air conditioner, such as compressor malfunctions.

3. Small air conditioner size

Many people may resort to purchasing a small air conditioner that may not fit the size of the room they want to cool. This is done for the following purposes:

It reduces electricity consumption, but this results in the air conditioner not being able to cool the place.
Because its capabilities may be weak compared to the place you want to cool, it is important to ensure that the air conditioner you want to buy is suitable for the place you want to cool so that it can do the job without causing any problems after purchase and installation.

4. Thermostat malfunctions

The thermostat is one of the essential components of an air conditioner. It regulates the temperature in the room or space to be cooled, then senses the compressor to start the cooling process.

If there are malfunctions in that part of the air conditioner, the cooling process may stop and thus the air conditioner will not perform its cooling function.

5. Clogged air filters inside the air conditioner

One of the most common reasons for the air conditioner not blowing cold air is a blockage in the air conditioner's internal filters. This blockage may be caused by:

Accumulation of dirt and dust in filters over time.
If your family travels for an extended period and leaves the air conditioner off, this may lead to dust buildup or clogged filters.
To fix this problem, you must remove the internal filters and clean them well with water.
You can use a sponge for cleaning, let it dry, and then reinstall it.

6. Low refrigerant level

The refrigerant gas is responsible for cooling and absorbing heat from the air in the room where the air conditioner is installed:

Therefore, the low cooling level is considered to be due to low gas levels, and the reason for this decrease is the presence of leaks in a specific place.
There are some things that confirm that the problem is due to a low cooling rate, such as the appearance of ice accumulating on the air conditioner's external parts, or hearing loud noises when the air conditioner is turned on.
The air conditioning works well on cold days or at night, unlike on very hot days.

7. Compressor malfunctions

The compressor is one of the most important parts of an air conditioner and is expensive because it is the part responsible for sucking air from outside into the room and is connected to the internal part of the cooler.

Its role is to convert the hot air in the room and absorb it and convert it into cold air.
When the air changes from hot to cold, the refrigerant turns into hot vapor.
Then it moves to the air conditioner compressor, and at that time the compressor works to draw air from outside.
This is done through several fans and air ducts, and the compressor continues this process and repeats it until the desired temperature is reached.
If the compressor breaks down, this is one of the reasons for weak cooling in the air conditioner. Therefore, an air conditioning technician must be present to check the compressor and ensure that there is no problem with it.
In case of a malfunction or problem, it will be replaced immediately.
Compressor malfunctions It consists of:

1. The air compressor keeps running. This is one of the problems that the air conditioner compressor is exposed to. It is caused by the accumulation of snow in the compressor, or its continued operation is caused by the accumulation of dirt and dust.
2. Another problem that the compressor may be exposed to is not operating properly. The malfunction is caused by a malfunction in the air conditioner's cooling cycle or a leak in the refrigerant gas.
3. The fan is damaged and blocked due to debris buildup, which prevents the compressor from getting rid of hot air, thus disrupting the cooling system.
4. The compressor makes loud noises. Sometimes we hear loud noises that resemble crackling sounds. This indicates problems with the electrical controls or mechanical problems with the compressor.

8. Dirty condenser coils

Condenser coils are responsible for converting the refrigerant gas into a liquid before it is converted into vapor, which may lead to:

Dirt may cause a malfunction in the cooling system, which in turn leads to poor cooling in the air conditioner.
In this case, the condenser coils must be thoroughly cleaned using compressed air to remove dirt and dust.
You can also spray a dirt and grease solvent to react with it and remove it.
Then clean it with water and spray it vertically, making sure to cover the electrical parts with a plastic cover to prevent water from reaching them.
Once you're done, you can dry it with compressed air again or leave it to dry completely.

9. The air conditioner does not cool or produce water.

First, you should know that most of the problems that air conditioners in your home are caused by people themselves.

This is in regards to closing the windows and doors of the room while their air conditioner is running.
Or they don't set the thermostat correctly to the desired temperature or through an accumulation of faults.
Not paying attention to air conditioner maintenance.
This leads to an increase in air conditioner malfunctions, which leads to many problems.
But as for the problem of no water coming out of the air conditioner, this is due to problems that are related to the drainage of water from the air conditioner itself, and the problem of water dripping from the air conditioner is one of the problems that appear widely and widely and results from a blockage in the drainage hose, which is caused by the accumulation of moisture on the pipes in a large way.
This then causes the problem of water dripping due to the accumulation of snow on the evaporator. To avoid any malfunctions in home air conditioners, we must avoid the causes that cause these malfunctions and contact specialists immediately so that the malfunctions do not accumulate over time and cause the air conditioner to stop completely.
