Is the air conditioner in your home not working properly because it blows warm or hot air when you want to use it to cool the room? Or no matter how long you’ve waited, the aircon still can’t cool your room like before? This is definitely an extra headache you don’t need! When your air conditioner does not work according to its nature, it will be a big problem especially if you live in a tropical country.
Air conditioners are complex systems that require the perfect combination of temperature, airflow, and pressure to work properly. So it is only natural that there are many possibilities for your air conditioner to fail in the process. Fortunately, an air conditioner that doesn’t work optimally doesn’t always require expensive repairs. Here are some things that can make your air conditioner not work properly!
Air conditioners have an optimal operating temperature (ambient temperature) at which they can operate at their most effective capabilities. If the temperature spikes beyond the optimum temperature limit, the efficiency of the air conditioner will automatically drop. Sometimes the air can get so hot that the central air not blowing cold air because the compressor stops working completely.
Wrong sizing of the aircon
A common mistake that most people make is that they buy air conditioners based on their budget and not based on the needs of the room. Small air conditioners in large rooms will find it difficult to cool the room at a hot temperature. Before buying an air conditioner, make sure that you choose the right size of the air conditioner for your room.
Faulty air conditioner remote
There may also be situations where the remote fails to send a temperature change signal to the air conditioner unit. To troubleshoot this, you need to replace your remote with a new one.
Dirty air filter
The most likely cause of why an air conditioner fails to successfully vent cold air is because there is insufficient airflow. The fan will move air over the evaporator coils, where it cools, and then circulated back to the room. If your air conditioner’s airflow is reduced due to dirty air filters, it may fail to circulate cool air and reach the desired temperature in your room.
The air filter is situated behind the front grille, which may allow access to the side engine opening. This allows you to clean or change the air conditioner filter as necessary. Also, when the evaporator coil appears to be extremely dusty, it needs to be scrubbed using a brush dipped in soapy water.
Dirty outdoor unit
The heat from the air is absorbed by the evaporator inside the air conditioner, which then radiates that heat outdoors (condenser). This is roughly how air conditioners work to cool our space. However, if the aircon condenser is unclean or covered in dust, it cannot dissipate heat. Because of this, it could be challenging for your air conditioner to cool the room.
What you can do is remove the air conditioner case, and clean it by lightly misting it with a garden hose to eliminate any dust or mildew that has accumulated around the air conditioner.
Broken condenser fan engine
The fan or fan engine may be broken if your air conditioner isn’t blowing cold air. When an air conditioner is operating properly, the fan will move air over the chilly evaporator coils before returning it to the room. If the circulating fan is not operating or is operating too slowly, there will be no airflow over the evaporator coils, which may cause the air to become too cold and even build ice within, further limiting airflow. It will be essential to disassemble the aircon unit in order to inspect it for damage because the fan and engine are located inside.
You need to make sure that the fan engine spins freely and the blades are in good condition. If you see the fan or engine blades are broken, you should replace them right away. You need to contact an expert to troubleshoot this.
Refrigerant running low or leaking
Turn off your air conditioner and call professional help immediately, if you notice these symptoms happened to your aircon:
- Ice growth in the outdoor unit
- Weird noise coming from your air conditioner
This might be happening because there is a refrigerant leaking in your unit. Running the air conditioner while it is in this state could harm the compressor, rendering it beyond repair.
The air cooling mechanism is similar to how blood moves through the body, and the compressor in the aircon acts just like a heart. If our hearts are injured, they won’t be able to pump blood effectively throughout our bodies. If the compressor in your unit is damaged, a malfunctioning air conditioner will automatically be unable to cool your room. If there is a problem, your air conditioner compressor may need to be changed. Unfortunately, replacing compressors with new ones can be really expensive.
Problem with the capacitor
Some air conditioners also employ capacitors in the fan engine circuit, which frequently integrates both components into one unit. You will need to remove the cover of the air conditioner to inspect because compressors and capacitors are typically found inside. Even if there are no visible indicators of damage to the capacitor, you’ll still need a reputable air conditioner repair service to check it out using their professional tools.
