The air conditioner does not cool at night

Many people wonder why their air conditioner doesn't cool down at night, as it's one of the most important appliances used regularly, especially during the summer, to lower the temperature.

Due to the different types of air conditioners, there are a number of problems that can cause a malfunction or blockage, resulting in a continuous problem with the cooling process. So, let's learn together about the causes of this problem and its solution in these lines.

The air conditioner does not cool at night

One of the worst malfunctions that can happen to an air conditioner is the lack of cooling at night. This can be caused by several reasons, including the following:

1. Electrical faults

There are a number of electrical faults that can occur in air conditioning units, which may cause the cooling to stop during the day or night. These faults occur as follows:

Make sure the air conditioner is connected to the electricity and that all connections are properly connected.
If the air conditioner is connected to the electricity and is not working, make sure it is set to the required temperature.
There are mistakes that result in setting the hot setting instead of cold, or a child playing and changing the air conditioner setting.

2. Increase in external temperature

There are a number of external factors that affect the air conditioner, the most important of which is temperature. These factors are as follows:

One factor that may affect the efficiency and operation of the air conditioner is high temperatures.
There are high temperatures that the air conditioner cannot handle and cannot tolerate.
This results in malfunctions in one of the internal parts of the air conditioner.

3. The air conditioner size is not suitable.

When the air conditioner does not work at night, this may be due to choosing an incorrect air conditioner size, which can be as follows:

Some people buy small and unsuitable air conditioners to save electricity.
This results in the air conditioner not being able to cool the room, due to its weak capabilities.

4. Thermostat failure

This part is one of the components of the air conditioner that senses the temperature in the room, then senses the compressor to operate. Its problems include the following:

This part starts the cooling process inside the air conditioner.
If this part of the air conditioner malfunctions, the cooling process stops.

5. Blocked internal air filter

One of the main reasons why the air conditioner does not cool at night is because the air conditioner does not produce cold air. This is due to clogged internal filters. This happens as follows:

Blockage occurs due to the accumulation of dust and dirt on the internal filters over time.
Leaving your air conditioner off for long periods of time can cause dust to accumulate and clog the air filters.

6. Low refrigerant gas content

There are some signs that indicate that the air conditioner is not cooling at night due to a low cooling rate. The most prominent of these signs are:

Visible frost on the outdoor unit of the air conditioner.
There is noise when the air conditioner is running.
Work efficiently during cold days as opposed to hot days.

The air conditioner blows air without cooling it.

After learning about the reasons why your air conditioner doesn't cool at night, let's discuss the reasons for the air not cooling, including the following:

There is a problem with the heating system.
The size is not suitable for the place where it is placed.
Dust buildup on the air condenser.
Clogged air filter.
Compressor damage.
Coolant leak.

How do I make the air conditioner cool?

There are many solutions that can be used to solve any problem that may arise with the method, the most important of which is to follow the following steps:

Use the remote, then select Mood.
Select Cool from the menu.
Control the temperature you prefer.
Press the start button to start working.

The air conditioner blows hot air.

If you want to learn about the most important reasons that cause hot air to come out of a split air conditioner, read the following:

Compressor fault.
Filter clogged.
Freon leaking from pipes.
There is a problem with the capacitor.
There is a problem with the evaporator.
Extension failure.

Why is the new air conditioner not cooling?

When buying a new air conditioner, owners often complain that it doesn't cool down at night. We've listed a number of the most important reasons for this in the following points:

Ice formation around the evaporator.
Neglecting maintenance and follow-up of the air conditioner.
The internal filter is clogged due to dust accumulation.
Obstruction of the airways.
Expansion valve problem.
Refrigerant leak.

The air conditioner does not cool or produce water

If there is a problem with the air conditioner not cooling or water coming out of the air conditioner, you must implement one of the following solutions:

The device must be checked whether it is installed correctly or not.
You should make sure that the air conditioner is placed in a suitable location.
Find out the specific cooling power of the device, and whether it is suitable for the room.
The temperature setting of the air conditioner must be checked.
Check that the filters are not dirty, clogged or dusty.
The condition of the evaporator coils inside the air conditioner must be checked.

The air conditioner is not cooling in the car

The problem of the air conditioner not cooling at night can occur in the car, at home, or in any air conditioner. The most important causes are the following:

Freon gas leak.
There is a hole in the car's radiator.
Problem with the connections inside the car.
Dust buildup on the air conditioner filter.
The type of air conditioner is not very suitable for the car.

The air conditioner only works as a fan.

This condition occurs in many different air conditioners, and is often caused by one of the following reasons:

The air conditioner needs lubricating oils.
There is a problem with the electrical circuit.
Clogged air filter.
Freon gas escape.
Cooling circuit problem.
Thermostat fault.
Fault in the air conditioner's outdoor unit.
Compressor problem.

Reasons why the split air conditioner does not cool

There are a number of reasons why an air conditioner, especially a split type, may not cool down at night. You can learn about them below:

Lack of cooling.
There is a blockage in the filters.
Ice builds up around the evaporator.
Dirty outdoor unit.
There is a problem with the compressor.
Capacitor damage.

How do I know if the air conditioner needs gas?

You must ensure that there is a shortage of Freon gas in the air conditioner, by using any of the following:

Low pressure gauge.
Ampere meter.

If the reading is lower than the required pressure, the amperage is significantly lower than normal, and there is ice accumulating on the discharge line, this indicates a shortage of Freon gas in the air conditioner.

How do you stop the air conditioner from turning off?

You must follow a set of important steps in order to maintain the air conditioner, and these steps are as follows:

Working on adjusting the air conditioner thermostat.
Make sure to clean the air filters regularly.
Ensure frozen evaporator coils are adjusted.
It is necessary to clean the condenser coils regularly.
