If you are experiencing problems with your air conditioning unit, there are certain actions you can take to see if the issue is something that can easily be fixed or if you have a more complex problem on your hands which needs professional services from a qualified HVAC technician. If you regularly change your air filters and there seems to be no issues with air flow blockage, then the simple troubleshooting steps below might help you out.
Reset Circuit Breaker
The initial step before trying anything else is to locate the circuit breaker for your air conditioning unit. Once you locate it, simply turn it OFF and then switch it back ON to reset it. By resetting the breaker, this can sometimes be all that is needed to fix any malfunctions of an AC unit. Many times, the breaker can be triggered into the OFF position without you noticing it on the electric panel. It is really easy to reset the breaker yourself and should be the first thing you look for prior to contacting an HVAC contractor. However, if you reset the breaker and it does not assist with the problem or you notice more significant issues like sparks or popping noises when resetting it, this can indicate a much more severe issue and you should definitely contact a professional HVAC technician right away.
The compressor is a very important component of your unit and should be checked out for any signs of damage. Should it fail, your entire unit will fail so the next thing you should be looking for if resetting the breaker did not work is the compressor. Check for any signs of ice build-up around it as well. Any signs of ice build-up or other damage will require you to seek assistance from a licensed contractor who may need to replace the compressor for you.
Blocked Air Flow
Dirt, lint, debris and other forms of airborne pollutants accumulating on your unit can be another problem. These types of pollutants if not taken care of can build up on various parts of your air conditioning unit including the filter and fan blades. You will need to open and clean out your unit to restore air flow that has been blocked. First, clean the filter or you might need to replace it altogether and then wipe off the fan blades and any other parts where dust has collected. You should check for blocked vents around your home. Furniture like chairs and your sofa could be blocking airflow.
When using your AC unit, pay attention to its efficiency and how it is running. Even the smallest deterioration of air quality may indicate it is in need of cleaning. How often you clean it will depend on how often you use the unit. The dirt and debris in the unit typically comes off from its filter and then traps the particles in the air before it emits it. By changing the air filters regularly, you can help maintain cleaner air and avoid other more severe and costly issues.
