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

For the 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.
