Regardless, here are 6 essential troubleshooting steps you can take to help restore optimal performance!

What are common AC problems?

Common air conditioning problems include the following:

  • Inadequate cooling – Your air conditioner is not cooling the air sufficiently.
  • Poor airflow – The air flow from the AC may be weak.
  • Unusual noises – Your AC may be making loud or strange noises.
  • Leaking water – Water or other liquids may be leaking from the unit.
  • Musty smells – Musty odors may be coming from the vents.
  • Thermostat problems – Your thermostat may not be working properly.

All of these issues can be caused by something as simple as a dirty filter or worn parts in need of replacement. However, if the problem persists after cleaning/replacing filters and other components, you may need to take additional measures. It’s important to call a professional appliance repair technician for help.

What causes AC failure?

There are several potential causes of air conditioner failure, such as: 

  • Dirty filters – Dirty or clogged filters can block the airflow, reducing efficiency and leading to premature failure.
  • Refrigerant leaks – A refrigerant leak from a damaged line, evaporator coil, or other component reduces cooling efficiency and increases strain on other components.
  • Faulty wiring – Faulty wiring can cause electrical problems and reduce the efficiency of your AC system. 
  • Worn parts – Worn or damaged parts such as compressors, blower motors, fan blades, or condensers can also lead to failure. 
  • Thermostat problems – Issues with the thermostat can prevent the AC from operating properly. 

If your air conditioner is malfunctioning, it’s important to identify and address the underlying cause of the problem as soon as possible. If you’re unable to diagnose or repair the issue yourself, be sure to call a professional appliance repair technician for help. Doing so can save you time, money, and hassle in the long run. 

How do you test AC function?

The easiest way to test the function of your AC is to turn it on and let it run for a few minutes. If there’s no cool air coming from the vents or if something is not working as intended, then you’ll need to diagnose the issue and search for a solution. 

6 AC troubleshooting steps to take

Here are some steps you can take when you’re having trouble with your air conditioner.

  1. Check your filters

The first step is to make sure your filters are clean and free of debris. Dirty filters can reduce airflow, causing the air conditioner to overwork itself and eventually fail. 

  1. Clean the unit

Next, clean the outdoor unit to remove dirt and debris that may be blocking airflow or causing other issues. You can use a hose to lightly spray down the unit or use a vacuum cleaner with an attachment meant for cleaning AC coils.

  1. Check the thermostat

Make sure your thermostat is set correctly and functioning properly. If the temperature setting is too high or low, the air conditioner won’t be able to regulate the temperature of your home effectively.

  1. Reset the system

If the air conditioner is still not cooling properly, try resetting it by unplugging the unit and plugging it back in. This will allow the system to reset itself and may help resolve any minor issues.

  1. Check the power supply

If the AC unit is still not working, check the power supply to ensure that it’s properly connected and functioning correctly. If you find any issues with the wiring or connections, have a professional electrician inspect and repair them.

  1. Check for refrigerant leaks and call for service if needed

Finally, if all else fails, you may need to check for refrigerant leaks. This is something that should only be done by a professional appliance repair technician, as it requires specialized equipment to detect and fix any leaks.

If you can’t identify or repair the issue yourself, you should definitely contact a professional air conditioning technician for help.


In conclusion, regular maintenance and timely repairs are essential for keeping your air conditioner running smoothly. By following these 6 AC troubleshooting steps, you can identify and resolve common issues quickly and efficiently without having to call an appliance repair technician. 

However, if the malfunction persists or requires more complex repairs, it is advisable to turn to professionals for assistance. By doing so, you can save yourself time and money in the future, as well as avoid any unnecessary frustration.
