In our quest to always provide you with the best customer service, you may find the following list of troubleshooting techniques helpful when you are experiencing problems with your heating or cooling system. It is important to understand however, when you attempt to repair your system without the help of an AC contractor, you are proceeding at your own risk. If your heating or air conditioning system isn’t working, there are a few basic troubleshooting steps you can try if you want to attempt a self-repair.
|√||Check your thermostat setting.
Make sure that it is set to the “on” position. If it isn’t, set it to the “on” position. If your digital thermostat screen is still blank, you may have lost power. This could be a problem of either high or low voltage.
|√||Check all your AC unit breakers and disconnect boxes.
Make sure they are all set in the “on” position. If they are not, switch them to the “on” position. This should fix your high voltage problem. When the breakers and disconnect boxes are returned to the “on” position, the thermostat screen should light up and the unit should begin working again.
|√||Check your drain line to make sure AC unit is draining.
If the drain is clogged, the float switch will disconnect the low voltage, shutting off the unit and the thermostat will be blank. You can try clearing the drain line where it terminates outside with a Wet Shop Vac.
|√||Check your Dehumidistat setting.
If you plan on being at home, it should be set in the “on” position.
|√||Check to make sure your AC unit filter is clean.
If you don’t know where your air filters are, or you can’t access them, check your vents for airflow. No air flow usually means air filters are dirty and needs to be changed. Clean filters help contribute to home energy savings.
