1.      Check Thermostat

The thermostat is the first thing you should be checking.

  • It should be set to cool
  • Check whether anyone adjusted the temperature
  • If it is OFF, set it to heat before turning it to cool
  • After setting to cool, wait for a few minutes to hear the cooling unit get started
  • Check for any signs of cold air

2. Check Air Filter

If there is no cold air from the above-mentioned test, conduct this test. A dirty air filter is going to make a big impact on the performance of your cooling system. The best strategy will be to regularly check the filter for any signs of a build-up of dirt and replace them accordingly.

Once they get clogged, it stops working to keep out debris from your AC unit’s components. Make sure the system is completed powered off before you check and remove the air filter.

3. Check Condenser

If your air conditioner has an outdoor condenser unit, chances are that its coils are blocked or clogged. Since this unit is kept outside, it is open to all forms of treatment from the elements. It can also get filled with different types of debris including:

  • Dirt
  • Dust
  • Organic debris
  • Insects

Your AC may stop cooling because of a system malfunction due to this debris build-up.

  • Check the condenser for any signs of debris build-up
  • Use a vacuum with a brush fixture
  • You may also use a hose to gently wipe and remove the dirt

4. Evaporator Coil

There is an evaporator coil in your air conditioner that is responsible for removing heat and humidity from the air flowing through it. Your AC may be running but not cooling because this coil gets frozen.

Some of the common signs of a frozen evaporate coil are as follows:

  • Sudden and unexplained increase in energy bills
  • Frost build-up on the refrigerant tubing
  • Ineffective cooling
  • Excess drainage of condensate

It is best to let an experienced and qualified technician handle this type of troubleshooting and repair.

Some of the other common issues that could be causing your AC not to cool include leaking refrigerant and leaking ducts in Ducted air con Sydney systems. A licensed professional will have the experience, skills, and equipment required for safely troubleshooting and fixing the problem. As already mentioned, it is best to maintain your air conditioning system regularly. This can help eliminate any potential issues when you need your AC the most.
