Common Air Conditioner Problems and Repairs

  • Air-conditioner not running at all: Before hiring or calling an aircon technician, there are a few things you can check. Firstly, ensure the thermostat is set to “cool” and the temperature is set correctly. 

Next, locate your main fuse panel, and determine if the fuse or circuit breaker has been blown or tripped. For a blown fuse, simply replace it and see if your AC turns on. 

For a circuit breaker, simply reset it and check the AC again. If all these things do not work, call an aircon technician.
  • Aircon is frozen: If your aircon is frozen, the cause could be blocked or restricted airflow preventing the unit from working properly. In this case, you can try washing and cleaning the air filters. The coils should also be free of dirt and debris. It is best to engage an aircon professional to look at this issue.
  • Warm air or no air: There are several factors causing this. Before engaging an aicon technician, look at the outside unit and ensure no debris (such as leaves and branches) blocking the airflow to your air-conditioning unit. 

Check ductwork to ensure it is still attached to your vent system. If these actions still do not solve the proble, it could mean your aircon is low on refrigerant. In this case, it is advisable for you to call an aircon specialist to handle the issue
  • Drainage issues: Should you spot any leakages in and around your unit, the unit’s condensation line may be clogged. If water is visible in the drip pan, you may attempt to DIY unclog the line by blowing compressed air inside the pipe to remove any obstruction. 

If these actions do not work, it is advisable to engage an aircon specialist to unclog the line.
  • Constantly running or switching on and off: This usually mean sizing issue with your AC. If the unit is too large for your home, it will cycle on and off often. If the aircon power is too small, your unit will run constantly to keep your home at the desired temperature. 

There are many other factors that could cause improper cycling, such as air-conditioning unit being low refrigerant, faulty thermostats, and faulty relay switches. It is advisable to engage an aircon specialist if this is the issue.

When do I replace my aircon and when do I repair?

The decision to choose whichever option can sometimes be tough and require a good judgement. The general advise is that if it is relatively new and can be fixed with a low cost repair, the answer is obvious – repair your unit.

Should your aircon be more than eight years in operation, you may want to replace it. This is because air conditioning units is undergoing constant improvement in terms of energy efficiency and environmental friendliness. Replacing a brand new aircon can make more economic sense if it can bring greater cost saving to you over the long run.

It is advisable to have inspection after some time even if your aircon is working properly as small leakages or faulty ductwork can undermine the efficiency of your air conditioning units. Technicians can spot these problems before they turn into major nightmares when it gets big, helping you reap the most benefit from your existing aircon system.


With some research and checking of directories, you will be able to find aircon professionals who can help you with making the right decisions regarding your air conditioning needs.

Should your AC unit be working for a number of years, it may be more cost effective to replace it rather than engaging in expensive overhaul or repair works.

When searching for a new air conditioning system, we advise you to consider energy-efficient and eco-friendly units for long term savings.

Lastly, engage in regular aircon maintenance projects to ensure your AC units last longer.
