Common AC Problems and How to Fix Them

In Singapore’s hot and humid climate, having a well-functioning air conditioning system is essential. However, like any appliance, your aircon unit can develop issues over time. Knowing the common air conditioning problems and how to address them can help you avoid costly repairs and keep your home or office cool and comfortable.

At Airssen, we believe that early detection and routine aircon maintenance are the best ways to prevent breakdowns. Here are the most frequent AC problems and how to handle them.


1. Lack of Airflow

If you notice weak or uneven airflow coming from your aircon vents, it may be due to:

  • Clogged air filters
  • Blocked air ducts
  • Dirty evaporator coils

How to Fix:
Check and clean your filters regularly. Schedule a general aircon servicing or deep cleaning to remove dust and blockages that restrict airflow.


2. AC Not Cooling Effectively

An aircon that blows warm air or doesn’t cool the room effectively could have:

  • Low refrigerant levels
  • Dirty condenser coils
  • A faulty thermostat

How to Fix:
Ensure the thermostat is set correctly. If cooling remains weak, you may need a refrigerant top-up or professional inspection from an aircon technician in Singapore.


3. Unusual Noises from the AC Unit

Grinding, buzzing, or clicking sounds may indicate:

  • Loose parts
  • A failing fan motor
  • Electrical issues

How to Fix:
Turn off the system and call for aircon repair services. Avoid using the AC until a qualified technician can diagnose and fix the mechanical issues.


4. Water Leaks or Dripping

Water dripping from your indoor unit may be due to:

  • Clogged drain pipes
  • Frozen evaporator coils
  • Improper installation

How to Fix:
Clean the drainage system and check for leaks. If the problem persists, contact a professional aircon servicing company in Singapore for inspection.


5. Compressor Issues

The compressor is the heart of your air conditioning system. If it fails, your AC may stop cooling altogether. Common signs of a failing compressor include:

  • AC not turning on
  • Warm air even when the system is running
  • Frequent circuit breaker trips

How to Fix:
Compressor issues usually require expert repair or replacement. Book a diagnostic check with Airssen to prevent further damage.


Importance of Regular Maintenance

Many of these problems can be avoided with routine aircon servicing. Regular maintenance helps:

  • Improve cooling performance
  • Extend the lifespan of your unit
  • Reduce energy bills
  • Prevent emergency breakdowns
