Thermography is the art and science of taking and studying thermographic images. These images show very minute differences in heat radiating from objects. Basically, it they show us hot and cold spots that with proper training we can interpret as useful information.
What can thermography find in our homes?
Missing insulation in exterior walls and attic
Leaking AC ducts in the attic
Underperforming AC components
Termite and ant nests inside walls
While Thermography is very useful it has its limitations. For instance:
It can’t see through anything that infrared waves won’t pass through.
It needs functioning AC inside the structure to find missing insulation.
