Possible Causes
Controller Settings
Before jumping to conclusions about a malfunction, it’s best to check your controller settings first. Ensure that it’s set to the desired mode and that the temperature is set correctly. Sometimes, the problem is as simple as an incorrect settings.
Clogged Air Filters
Air filters play a crucial role in maintaining airflow and air quality. Over time, they can become clogged with dust and debris, restricting airflow and reducing the system’s ability to cool your space. This is why it is important to ensure your air con units receive services so we can check your filters and replace or clean them if they appear dirty or haven’t been changed in a while.
Low Refrigerant Levels
Low refrigerant levels are a common culprit when your air conditioner isn’t blowing cold air. Refrigerant is essential for the cooling process, and if levels are too low due to a leak or improper charging, your system won’t be able to cool effectively. This issue would require our team of professional engineers to inspect, repair if required and recharge the system with the correct type and amount of refrigerant to ensure proper operation.
Dirty Condenser Coils
The condenser coils on your outdoor unit can accumulate dirt and debris over time, reducing their ability to dissipate heat. When the coils are dirty, the system has to work harder, which can lead to reduced cooling performance. Cleaning the coils can help restore the system’s efficiency and this is part of our regular air con servicing.
Faulty Compressor
Leaky Ductwork
Leaky ducts can cause cooled air to escape before it reaches your living, or working spaces, leading to insufficient cooling. Our team would inspect the ductwork for any visible signs of damage or leaks, and repair if needed.
Electrical Issues
Sometimes, the problem lies with the electrical components of your air conditioning system. Faulty wiring, blown fuses, or tripped circuit breakers can all prevent your system from functioning. The electrical connections would need testing and any tripped breakers resetting to see if that resolves the issue.
Blocked Condensate Drains and Faulty Pumps
Air conditioning systems have a condensate drain to remove moisture. If this drain becomes clogged, it can cause water to back up and affect the system’s performance. Clearing the blockage can help restore proper cooling. Many systems make use of condensate pumps and if blocked can prevent the system from running to avoid water damage. This is something you will need our team to resolve.
What Should You Do?
If your air conditioner is not blowing cold air, start with the simple checks like thermostat settings. If that doesn’t resolve the issue, it may be time to call in our professional team of HVAC engineers to assess the system. Regular maintenance can prevent many of these problems and ensure your system runs efficiently year-round.
Here at AAC Southern, we offer comprehensive air conditioning maintenance and repair services to keep your system running smoothly.
