I am a snow bird from North US and go to warm weather in Winter. I winterize my house in the North with only Oil Furnace, and a Fridge on. No other appliance is kept on. For most winters my electric usage ( and the bill) was quite low. This winter however every month it was 3X the normal. I called the Electric Utility. They suggested may be one of the 2 appliances was using a lot of electricity.
Is it possible for a fridge to use 3X more electricity? If yes how do I confirm that? Is there a Test device that will tell how many KWH the appliances are consuming?
