Frequently Asked Question - Keep doors and windows closed.
Keep doors and windows closed.

Imagin your house is a glass of water. Your doors and windows represent what would be holes in the glass if you left them open. Water is just like the cold air in your house, when you open a door or window the cold air rushes out and is quickly replaced with warm humid air. With this said, keep your doors and windows closed during heating or cooling or your just throwing money out the window.
