The reason why your air conditioner is not cool enough?
Failure to clean the filter regularly causes the filter to be covered with dirt, the air conditioner has to draw air in and push out less, but the power consumption is higher than usual.
Thus, higher power consumption, more noise but not good cooling effect.
To overcome the above situation, you should clean the filter regularly about once a month (depending on the level of use). For families in the North, it is necessary to thoroughly clean the machine before entering the summer to ensure that the air conditioner achieves optimal cooling efficiency.
2. Air conditioner is missing or out of gas
Improper assembly causes the gas pipeline to leak or be used for a long time without gas filling, causing insufficient gas to cool the air.
When running out of gas, common symptoms are:
- Snow clings to the small pipe valve of the indoor unit.
- The operating current is lower than the rating indicated on the machine.
- Newer air conditioner product lines usually automatically shut down after 10 -15 minutes and report an error.
When you encounter the above symptoms, you should go to a reputable maintenance and repair center for timely support. In particular, you should check and clean the machine overall for 3 months or more to keep it working properly.
3. Compressor is broken
The compressor is an important part for the air conditioner, when the compressor fails, the air conditioner still works normally but the air blown out from the machine is not cooled.
There are many causes of compressor failure: loss of power supply, control circuit failure, …
This part requires a professional repairman to promptly check and fix it, avoiding the case that the customer will replace the whole thing with a new one, causing waste.
Damaged capacitors and circuit boards will turn the air conditioner into a regular blower.
- The air conditioner is overloaded.
- The air conditioner is maintained at too low a temperature (below 20 degrees Celsius) continuously for too long.
How to fix:
- Contact the service center to replace the capacitor, circuit board.
- To minimize damage to the condenser, only maintain the air conditioner at a temperature of 25 – 27 degrees Celsius.
- Regularly clean the circuit board to prevent insects and spiders from nesting, causing short circuit boards. When cleaning, the power must be turned off to ensure the safety of the user.
In the hot summer, the family’s demand for electricity increases, causing overload in many areas. Weak and unstable power supply causes the compressor (machine block) to overheat, have poor cooling capacity or stop working.
On hot days, you should use an additional voltage stabilizer to stabilize the power source, ensure that the air conditioner always works well to meet the cooling needs of your family.
The air conditioner runs on water for a long time, forming a layer of moss on the drainage pipe, causing a blockage that prevents water from escaping. Since then, the cooling capacity of the air conditioner is also significantly reduced.
Contact the service center immediately to have the drain hose cleaned or replaced.
Note: The water pipe is sloped enough for the water to easily drain out.
Setting the wrong cooling mode is one of the reasons why your air conditioner is not cool. This may come from you mistakenly turning on other function buttons such as heating, fan, …
To be sure to turn on the correct cooling mode, you need to understand the different symbols, some common symbols you need to know:
Cool: Snowflake shape
Dry: Water drop shape
Heating mode: Sun shape
8. Block air conditioner not working
Blocking the air conditioner not running also leads to the air conditioner not cooling. This can be caused by the following:
The compressor has no power supply: Due to the control board, the circuit is open or the contactor is not closed.
Thermic machine protects the compressor: Due to damage to the capacitor, the outdoor unit is damaged by the fan, the compressor motor is not working properly.
Burn the motor windings on the inside.
To fix this situation, you first need to find out exactly what causes the air conditioner block not to run. In case of a motor coil fire, you should replace it by repairing only for a while.
Install the indoor unit facing the wind direction
In places with a lot of wind, do not install the truss facing the wind direction, because the wind causes the air conditioner to dissipate and cause the air conditioner to work harder to provide enough cooling. Ideally, install the temperature air conditioner perpendicular to the wind direction.
Install the air conditioner in the corner of the hot wall
Given the limitations of the appropriate installation area or angle, this installation situation is quite common. However, this easily leads to the condition that the air conditioner must run overloaded when it has to cool the superheated wall first and then the air in the room.
Instead, you should install the air conditioner in cool corners so that the temperature in the room drops quickly and then slowly cools the surrounding walls. However, it should also be noted that the conduction system should not be pulled between the outdoor and cold units for too long because that way the system will not work optimally.
There is a myth that turning on the air conditioner at the lowest setting will make the space cool and cool faster without affecting the life of the air conditioner.
However, in fact, when you turn on the air conditioner and choose the lowest temperature for many days in a row, it will make your air conditioner work worse, even severely damaged.
It is best to choose the average mode when turning on the air conditioner at 25 – 27 degrees Celsius or the difference with the outdoor temperature is about 5-7 degrees Celsius. This temperature also helps the machine to operate efficiently and increase its lifespan.
This air conditioner capacity is governed by many things such as the heat source in the room, building materials, room size, number of users.
In particular, in order for the air conditioner to work efficiently and cool the air better, you should choose the right air conditioner for the installation space.
Here are some suggestions for installing the right capacity for the area:
Rooms under 15m2 should use air conditioners with a capacity of 9000 BTU.
Rooms from 15-20m2 should choose to buy an air conditioner with an operating capacity of 12000 BTU.
Rooms from 20 – 30m2 should choose an air conditioner with a capacity of 18000 BTU.
Rooms from 30-40m2 should choose to buy with a capacity of 24000 BTU.
Hopefully through the above article of eLib, you will have a better understanding of some of the causes and how to fix common problems that make the air conditioner not cool!
