Air Conditioner Repair

Troubleshooting your faulty air conditioner

Before you call in the experts, there are some things you can test yourself.

  1. Make sure the air conditioner is plugged into the electrical outlet. If the unit is plugged in, check the fuse and circuit breaker to see if they have tripped.
  2. Set the thermostat to cool and lower the temperature to 18-20 degrees. If your air conditioner won’t cool the room still, the issue could be due to a dirty air filter.
  3. Clean around the outdoor unit and remove any leaves or debris that may be blocking the airflow.
  4. Dirty air filters can restrict the airflow and also cause the evaporator coil to freeze. So pull out your filter and check if you can see through it. Give the filter a thorough clean or replace it if needed. Note: If you use your aircon often or have pets, you may need to clean and replace the filters regularly to avoid issues.
  5. Check if there’s any ice inside the unit. This can happen due to a dirty air filter, refrigerant leak or clogged evaporator coils. If your air conditioner is frozen, turn off the unit and contact a professional aircon repair company.
  6. If you have followed these steps and you still cannot solve the problem, contact your local air conditioning repair technicians.

3 Reasons why your air conditioner running but no cooling the house

Before you go, you might want to read about the potential reasons for your aircon troubles so you can avoid them in the future.

1. Dirty or clogged air filters

The air filters can get dirty and trap dirt over time (that's actually their job). If the filters are not cleaned regularly or replaced, the cool air flow will be blocked and the air conditioner won’t be able to cool your room effectively. Over time, this restriction of flow can damage the evaporator coils, condenser and cause the unit to fail prematurely.

2. Dirty condensor coil

If the condenser is dirty, the heat transfer process will slow down. The heat will begin to accumulate in the condenser and the condensing temperature would rise. Long story short, the aircon would run, but the efficiency would drop significantly. Your home will feel more humid and your aircon won’t be able to cool your room despite running for hours. Your AC might also start blowing hot air.

A dirty condenser will affect the functioning of the condenser and your unit might even breakdown if you do not get it fixed.

3. Aircon refrigerant leak

Refrigerant gas can leak out slowly and cause the aircon efficiency to drop drastically. This is often due to poor workmanship or undercharged gas at the time of installation.

If you can hear a hissing sound from the outdoor unit or your unit is freezing up, it could be a sign of refrigerant leaks.

Note: Refrigerant leaks are harmful to the environment and your health, so contact professionals immediately to test for leaks and replace the refrigerant.

The best way to avoid aircon failures is by regular inspection and servicing. It will prevent breakdowns and you will be able to save money on emergency repairs. Regular servicing also ensures the system is in peak condition and you stay cool on those hot and muggy days.
