How to Test Your Home for Energy Loss
The Dollar Bill Test
Place a dollar bill between the door and jamb or between the window sash and sill. With the door or window closed attempt to remove the dollar bill. If it slides out easily, you are losing energy.
Flashlight Test
Shine a flashlight around the edges of your door at night. If you can see light from the other side, you are losing energy.
Moist Hand Test
Pass a moist hand around the edge of your doors and windows. Where you feel a draft you are losing energy. This test works best on cold, windy days.
