Air Conditioner Troubleshooting
If your air conditioner isn't working properly, here are a few questions to ask yourself and common issues that could be causing your problem.
IS YOUR THERMOSTAT SET?
- Make sure your thermostat is set in the cool position (or heat, for winter heat pump operation).
- If it is, confirm that your outdoor air conditioner or heat pump is running.
IS THE POWER ON?
- See if your circuit breaker has been tripped to the OFF position.
- Confirm the outdoor disconnect switch on your outdoor unit is in the ON position.
- You can usually find the disconnect switch mounted on a wall near the outdoor unit. It's typically a small, gray metal box.
- Make sure the blower motor in your furnace or air handler is running when your thermostat is turned on.
- Check that the furnace switch is in the ON position.
IS THERE PROPER AIRFLOW?
- See if your air filter is dirty, and change it if it is with the same size.
- A blocked filter can cause your unit to shut down due to improper airflow.
- Make sure air registers (supply or return ducts) are clear.
Gas Furnace Troubleshooting
If your gas furnace isn't working properly, here are a few questions to ask yourself and common issues that could be causing your problem.
IS YOUR THERMOSTAT SET?
- Make sure your thermostat is set to the heat position.
- Confirm that the temperature setting on the thermostat is set higher than the thermostat's indoor temperature.
IS THE POWER ON?
- Make sure the power is turned on for your furnace.
- Turn the fan to ON at your thermostat. The fan should run when power is being supplied to the furnace.
- See if the circuit breakers in the circuit breaker box (or electrical panel) tripped to the OFF position.
- Check the SSU light switch on the gray box located at the furnace to make sure it is in the ON position.
IS THERE PROPER AIRFLOW?
- See if your air filter is dirty, and change it if it is.
- A blocked filter can cause your unit to shut down.
- Make sure air registers (supply or return ducts) are clear.
