If your air conditioner is not producing cold air, there are a few easy steps you can take to try and fix the problem:

  1. Check your thermostat: Make sure your thermostat is set to “cool,” and the temperature is set lower than the current room temperature. Also, check that the batteries are still good and the display works properly.
  2. Check the air filter: A dirty air filter can block airflow, causing your AC unit to work harder and not cool as effectively. Check and replace the air filter if it is dirty or clogged.
  3. Check the condenser unit outside: The condenser unit outside can become dirty and clogged, which can reduce airflow and cause your AC unit to work harder. Clean the unit and clear away any debris or vegetation around it.
  4. Check the evaporator coil: If it is dirty, it can reduce airflow and cause your Aircon unit to work harder. You Clean the coil using a soft brush or vacuum cleaner.
  5. Check for leaks: A refrigerant leak can cause your Aircon unit not to cool properly. If you suspect a leak, contact a professional HVAC technician to diagnose and fix the problem.
  6. Check for blockages: Ensure no obstructions are blocking the vents or air ducts. Blocked vents or ducts can prevent airflow and reduce the cooling efficiency of your air conditioner system.
  7. Check the fan: Make sure the fan is working properly and blowing air out of the vents. If the fan is not working, contact a professional HVAC technician to diagnose and fix the problem.
  8. Check the power supply of your aircon unit. Make sure the power outlet is connected to the unit.
By following these easy steps, you can often fix the problem of an air conditioner not cooling. If none of these steps work, it may be time to contact a professional HVAC technician for further assistance.
