A/C Startup Checklist


1.  Check that you have turned your AC thermostat control to the ON or set it in the “cool” position.

  • This is the basic temperature control for your cooling system.


2. Confirm that the outdoor air conditioning (condensing unit) is running.

  • Check the circuit breakers inside your home. The circuit breaker box (or electrical panel), which will likely be mounted to a wall inside your house. Make sure they are all in the “ON” position.
  • Check the outdoor unit “disconnect switch” to confirm that it is in the “ON” position. The disconnect switch is by the outdoor unit. (Usually a grey 8″ wide x 16″ high x 4″ deep box mounted on the exterior house wall).


3. Check to make sure that the blower motor in your furnace is properly running in order to optimize performance. (The furnace blower should be running, if the thermostat is set to the “cool” position).

  • The blower motor is what will allow the forced air to circulate properly.
  • If it is not running, check the on/off switch on the furnace. It should be in the “ON” position.


4. Be sure to change out your furnace filter if you have not done so recently.

  • An excessively blocked filter will prevent air from circulating, which will cause your outdoor a/c unit to shut down because of the lack of proper airflow.


5. Check that all air return vents are open and clear and are not blocked by furniture.

  • Furniture should be at a minimum of four inches away from air return vents in order to facilitate adequate air supply.
