It is essential to make sure your AC is running properly because it can result to a more expensive repair or a huge electric bill. One of the most common reasons why your AC is running but not cooling is because of a clogged air filter. If that’s the case, you can totally clean and do it yourself without any professional help.

Aside from the air filter, according to this article, other reasons for this kind of problem is one of the following: Dirty coils, Insufficient coolant, Faulty compressor, Faulty thermostat, Defective parts, High atmospheric temperature, Undersized AC or Faulty AC Remote. If you have checked all of them and are still not sure what’s wrong with your AC, maybe it’s high time to let the professionals do it.

When you have a running compressor, but your air conditioning unit is not producing cool air, there are potentially a number of things that could be causing this problem. The first areas that should be checked and cleared can be completed easily and quickly. These are fixes that should be accessible to any homeowner. Other do-it-yourself options are also available to homeowners with more advanced handy home maintenance skills. If these options are expended, it may be time to bring in a professional HVAC technician to further diagnose what to do when your air conditioner is running but not cooling.

Also, If the air is blowing but it’s not cool, there may be a refrigerant leak. While a trained technician will have to charge the system, check out these other options before you call.

  • Check the air filter. If it’s dirty, change it, as dirt blocks airflow.
  • Clear obstructions away from the outdoor compressor.
  • Make sure the outdoor fan is working. If not, call a repair professional.

Is the air not blowing?

First, check the thermostat temperature to make sure it’s set a few degrees lower than the room temperature. You should also check the following:

  • The thermostat should be set on “cool.”
  • A dirty air filter may block airflow. Change it.
  • Make sure there’s power to the A/C by checking the switches to the outdoor compressor and the indoor air handler. Also, check fuses and circuit breakers.

If all the above troubleshooting didn't work please, call a technician.
