Checklist
1. Know where all of the units in your heating and cooling system are located.
2. Check to make sure that your thermostat is set in the "cool" or "heat" position.
3. Check the circuit breakers in the circuit breaker box (or electrical panel), most
likely mounted in the garage or the basement. Are they in the "On" position?
4. Ensure that your outdoor air conditioning (condensing unit) is running:
Check the outdoor unit "disconnect switch" to make sure it is in the "ON" position. The disconnect switch is located near the outdoor unit. (Typically a grey 8" wide x 16" high x 4" deep box mounted to the wall).
5. Ensure that the blower motor in your furnace is running. (If the thermostat is in the "cool" position, the furnace blower should be running.) - If not, check to make sure the on / off switch at the furnace is in the "ON" position
6. Be sure that you have changed your filter in the furnace recently. - An extremely blocked filter can cause your outdoor air conditioner unit to shut down due to lack of proper airflow.
- Your filter should be changed every month.
