Home Aircon Troubleshooting Guide – Given the island’s tropical climate, air conditioning units are a quintessential part of our lives.

However, aircon units can occasionally malfunction or become less efficient, creating discomfort.

Here’s a guide for easy troubleshooting tips that could bring your aircon back to life before reaching out to a professional.

Remember, these fixes are intended for common, non-technical issues. Always consult a professional for intricate problems.

Even with regular aircon maintenance, aircon units may need repairs from time to time. Read on – Home Aircon Troubleshooting Guide:

Unresponsive Aircon: Checking the Power Connection

Sometimes, the simplest solution is the right one.

If your aircon unit is not turning on, the first thing to check is its power supply. Ensure that:

  • The power cord is securely connected
  • The circuit breaker hasn’t been activated
  • The fuse remains intact

This quick fix can save you a service call and return your unit to normal operation.

Reduced Cooling: Cleaning or Replacing the Filters

Aircon units can lose their cooling effectiveness over time.

One common reason for this is a dirty or clogged air filter, reducing the airflow and cooling capacity.

Cleaning or replacing the filters is a task you can do on your own:

  • Clean the filters every two weeks during high-usage periods.
  • Replace them every few months or as recommended by the manufacturer

Refrigerant Leaks: Sealing and Recharging

Refrigerant leaks are a common issue in aircon units.

They reduce your system’s efficiency and are detrimental to the environment. Dealing with a refrigerant leak requires one to:

  • Identify and patch the leak’s source
  • Refill the system with the correct refrigerant volume

Professionals should ideally perform this task because of its intricate nature and the potential risks of handling refrigerants.

Ice Build-Up: Checking for Proper Airflow

Ice can accumulate on your aircon unit if the evaporator coil becomes too cold due to restricted airflow. Check for:

  • Blocked vents
  • A clogged filter

Both of which could limit air circulation. If the ice build-up persists after resolving these issues, a refrigerant leak might be the culprit, requiring professional assistance.

Leaking Water: Emptying the Drain Pan

Water leaks are another common aircon problem. Often, this issue can be resolved by:

  • Emptying and cleaning the drain pan

If your aircon continues to leak after this procedure, it might signify a more severe issue, such as a cracked drain pan or blocked condensate line, warranting professional intervention.

Strange Noises: Identifying Potential Issues

An aircon unit making unusual noises is a cause for concern.

Grinding, squeaking, or rattling sounds can indicate loose parts, while a buzzing noise might indicate an electrical problem.

If tightening visible screws doesn’t solve the issue, it’s best to call a service technician.

Foul Odours: Investigating the Source

If your aircon unit emits a foul smell, it could be due to various issues, such as bacterial growth on the evaporator coil or a clogged drain line.

Regularly cleaning your aircon unit, including the evaporator coil and filters, can often resolve this issue.

Uneven Cooling: Balancing the System

If some areas of your home are cooler than others, your aircon system might need balancing.

This procedure involves adjusting the system’s dampers to distribute air throughout your home evenly.

While you can attempt this fix, consider seeking professional help to ensure proper balance and avoid damaging the system.

Short Cycling: Considering the Thermostat

If your aircon frequently turns on and off, it might be “short cycling.” This issue can often be resolved by adjusting your thermostat:

  • Ensure it’s not exposed to direct sunlight or heat sources
  • These conditions can cause it to register incorrect temperatures

High Energy Consumption: Energy-Saving Practices

An unusually high energy bill might be your aircon system’s cry for help.

Frequent or unnecessary aircon use, keeping the temperature too low, or running an older, less energy-efficient unit could be potential reasons.

Adopt energy-saving practices like:

  • Using fans to circulate the cooled air
  • Keeping the aircon temperature at an optimum 24-25°C
  • Upgrading to a more energy-efficient model if your aircon unit is old

Fluctuating Temperatures: Checking the Refrigerant Levels

If your aircon is not cooling consistently or adequately, it could be due to low refrigerant levels.

Refrigerant is the substance that your aircon uses to remove heat and humidity.

While you can’t check refrigerant levels yourself, you can suspect this issue if you notice temperature fluctuations or if your unit takes longer than usual to cool your space.

If this is the case, call a professional for help.

Frequent Breakdowns: Considering Unit Replacement

Despite the best maintenance efforts, aircon units have a finite lifespan like any other appliance.

If your aircon unit is over ten years old and experiencing frequent breakdowns despite regular maintenance, it may be time to consider replacing it.

Modern aircon units are more energy-efficient and equipped with advanced features, offering better performance and potentially reducing your energy bills.

Prioritizing Safety: When to Call a Professional

Remember, while troubleshooting is practical, safety should always be a priority.

Suppose you’re unsure about any aspect of your aircon unit.

If the fixes mentioned above don’t work, or if the unit requires opening up or dealing with electrical components, it’s time to call a professional.

Aircon servicing in Singapore is easy to find and often provides comprehensive checks and repair services that ensure your unit runs smoothly and safely.
