Before calling for service on my furnace (or AC) is there anything I should check first?

Check to be sure your furnace and/or air conditioner are plugged in. Check that the breakers, and disconnects are turned on, and lastly, check to be sure the thermostat is set correctly. Also, make note of any strange noises or smells and inform your HVAC technician upon arrival.
