How to Troubleshoot Your Air Conditioning Compressor?

Are you dealing with an air conditioning compressor that isn’t working correctly? If so, you’re not alone! Many homeowners have to deal with their air conditioners malfunctioning or not working at all. Thankfully, you can try a few quick and easy fixes before you call a professional. In this blog post, they’ll go over some troubleshooting tips and tricks you can use to get your Air Conditioning Compressor running smoothly again. Read on to learn more!

Check the Power of Air Conditioning Compressor

If your AC compressor isn’t working, the first thing to do is check the power. Ensure the circuit breaker hasn’t been tripped and the fuse connected to the Air Conditioning Compressor hasn’t blown. If the breaker or fuse has been tripped or blown, then reset the breaker or replace the fuse.  Once you’ve checked the power, turn on your AC unit to see if it works. If it isn’t, move on to checking the thermostat.

Check the Thermostat of Air Conditioning Compressor

If you’re having issues with your Air Conditioning Compressor, one of the first things you should check is your thermostat. The thermostat is responsible for regulating the temperature in your home, so if it’s not working correctly, it can cause your AC compressor to malfunction.  To troubleshoot this issue, check if the thermostat is set to the correct temperature. Make sure the thermostat is set to cool and not heat. You should also check that the fan setting is set to “auto”, as this will ensure that the AC runs when needed. 

If these settings are correct, but the AC isn’t running, you may need to reset the thermostat. To do this, turn off the power to the thermostat and wait a few minutes before turning it back on. If the problem persists, you may need to replace the batteries in the thermostat or even replace the entire unit. 

Clean or Replace the Air Filter

The air filter in your air conditioning system helps to remove dust, dirt, and other particles from the air that passes through the system. Over time, the filter can become clogged or dirty, reducing the airflow and causing the compressor to work harder. As a result, it is essential to clean or replace the filter regularly. To clean the filter, you must start by turning off the power to the air conditioner. Once the power is off, open the cover on the filter housing and remove the filter. Inspect the filter for debris or buildup, and use a vacuum cleaner to remove any particles. Ensure you also check both sides of the filter and shake it out to remove any excess dust. Once the filter is clean, reinsert it into the filter housing and close the cover.

Once you have purchased a new filter, install it as you would for cleaning – turn off the power, open the filter housing, remove the old filter, and insert the new one. Then close the cover and turn the power back on.  

Check the Evaporator Coils

Evaporator coils play a significant role in the cooling process of your air conditioner. If these coils become dirty or clogged, your AC’s performance can suffer greatly. To check the evaporator coils, turn off the power to your AC unit and remove the access panel. You should then be able to see the evaporator coils. Inspect the rings for any dirt, dust, or grime buildup. If there are any, you can use a soft brush or cloth to clean them off. You can also use a vacuum cleaner with a soft brush attachment to clean the coils thoroughly. Once you’re done, replace the access panel and turn on the power to your AC unit.

Inspect the Condenser Coils

If you’ve gone through all the steps above and your air conditioner is still not working correctly, then it may be time to inspect the condenser coils. The condenser coils are located in the outdoor unit of your air conditioning system. They help remove heat from the air inside your home and release it outside. To inspect the condenser coils, you must turn off the power to the air conditioner. Then, open the access panel and check the coils for dirt or debris buildup. If you see any dirt, remove it with a damp cloth or vacuum.

Next, check the fins on the coils. These metal fins can bend easily, so use a fin comb to straighten them out and ensure proper airflow. Finally, inspect the fan blades for damage and make sure they are clean and debris-free. If you still have problems after inspecting the condenser coils, it may be time to call a professional for help. They can help diagnose any underlying issues with your air conditioner and repair it quickly and efficiently.

Check for Refrigerant Leaks

Refrigerant leaks can be a common problem in air conditioning systems. Refrigerant leaks can cause several issues, including decreased cooling performance and an increased risk of compressor damage. If your AC compressor is not working correctly, it’s essential to check for any signs of a refrigerant leak. To check for a refrigerant leak, start by looking at the connections between the components of your AC system. Make sure all of the links are secure and not damaged or corrupted. If there are any signs of wear or damage, they should be repaired or replaced immediately. 

Next, look for any signs of refrigerant leakages, such as oily residue or discoloration near the connections. Refrigerant leaks can also cause a hissing sound, which is often easy to hear when the system runs.  Refrigerant leaks can be dangerous and require special equipment to repair safely. Contact a professional for assistance if you find evidence of a refrigerant leak. A qualified technician can fix the leak and restore your AC system to proper working order.

Call a Professional

If you have done everything you can and your AC compressor is still not working correctly, it may be time to call a professional. Air conditioning technicians have the knowledge and experience to diagnose and repair any issue with an AC unit so that they can provide an effective and long-lasting solution. If you are having trouble troubleshooting your compressor, a professional can quickly identify the source of the problem and offer a viable repair solution. They can also inspect your unit for any other issues that could cause your air conditioning system to malfunction, ensuring the longevity and performance of your AC unit. 

When you call the technician, explain your issue in as much detail as possible so that they can bring the right tools and supplies to the job. This will help them troubleshoot your compressor quickly and effectively, saving you time and money in the long run. 

How to Clean AC Compressor for Optimal Performance?

Cleaning your AC compressor is essential to keeping your cooling system running efficiently. It would help to clean your compressor regularly to get the most out of your AC unit. That guide will walk you through the steps necessary to ensure that your compressor is kept clean and functioning at its peak performance.

  1. Disconnect the power to the AC unit. To do that, turn off the power source at the breaker box or unplug the unit from the wall.
  2. Remove the cover from the AC compressor. That will expose the coils, fans, and other components.
  3. Use a vacuum to remove dust or debris inside the AC unit.
  4. Check for any damage or wear and tear on the components. If any of them are damaged or worn, replace them before proceeding.
  5. Wipe down all the components with a damp cloth to remove any remaining dust or debris.
  6. Reassemble the AC unit and reconnect the power source.
  7. Test the system to ensure it is functioning correctly and that there are no leaks or other issues.

By following these steps, you can ensure that your AC unit will remain in top condition and perform at its best. Taking the time to perform regular maintenance on your AC unit can extend its lifespan and keep it running efficiently for years.


When your AC compressor is giving you trouble, it can be a daunting task to fix the issue. But don’t worry; with a few simple steps, you can troubleshoot and solve the problem independently. Start by checking the power supply, then move on to checking the thermostat, cleaning or replacing the air filter, inspecting the evaporator and condenser coils, and finally checking for any refrigerant leaks. If you still need help, call a professional to come out and inspect your system. With these tips, you should be able to find the source of the problem and get your air conditioner running efficiently again.
