Photo Album: Thermal Imaging Scanner Detects Heat in Walls in Belleville, IL

With the proper scanner, it can be easier to see where the heat in the house is being attracted to most.  When using this device the walls in a home are supposed to be all blue to show that the house is circulating air correctly.  When red on the screen shows up, that indicates warm air leaking from the outside of the home or from the attic.
