Ways To Trouble Shoot A Unit

There are several reasons why an AC unit will stop working; however, no matter the reason--it's inconvenient. To be ready at a moments notice, you need to know what to check in your central air system to find the source of the problem. Some are simple checks of the thermostat, while others require changing the air filter or disconnecting and reconnecting the power source of the system. The importance of knowing how to troubleshoot is to save you time and money if you can find and fix the problem yourself. There are times when you cannot troubleshoot the system and then you will need professional help.

Let's start with all the steps you can take before you call a professional:

-If you are experiencing difficulty with your central air system, start with your thermostat. Here you have direct control over the system to regulate airflow and temperature. Start by making sure the system is turned on through your thermostat. Yes, this is a simple step, but many people forget when they turn their system off to turn it back on.

-Check the temperature setting on the thermostat and make sure the temperature is not higher than what it should be functioning on. If the temperature is higher, then the system may not need to turn on and is the reason why you aren't receiving any air. Adjust that temperature to what you prefer and see if the fans of the system turn on.

-Again, this may sound basic, but check that the system is set to "cool" and not "heat." This could have accidently gotten moved without notice.

-If everything on the thermostat seems to be set properly then it's time to check other parts of the system. Start by selecting the breaker in your breaker box for the central air system. Sometimes a loss or surge of power can leave a breaker tripped and you need to reset it. Trying flipping the switch to reset the breaker and try to adjust your system to initiate the fans.

-Find your central air system, typically located in a basement, attic or garage and reset the system with a reset button or by removing and reconnecting the power supply. Be careful that you do not remove anything else that does not need to be disconnected.

-How about your air filter? If you haven't changed your air filter in a while then this could be the cause of your problem. Purchase a new air filter at a local hardware store and replace it with the old filter.
