I know that my habit of leaving my thermostat ON whole day is going to burn my pocket but still I can’t help it. I have two kinds whom I have drop to school every morning and in doing all the required things I forget to switch off a lot of gadgets.

My children come back to home before me and my wife and they have got a bad habit to jump to the HVAC system. Most of the times they keep changing the temperature of the room while watching cartoon in the living room.

For first few months, I couldn’t find any change in the electricity bills but after 6 months suddenly my energy bill gets doubled. I was shocked looking at the bills and start looking for the reasons behind this.
