We use a state-of-the-art infrared camera to find problems that aren’t always apparent to the naked eye. An IR camera translates the heat signatures of objects into colors on a gradient scale, with higher temperatures appearing as lighter colors, and lower temperatures and wet areas appearing as darker colors. By evaluating these images, I can detect sources of energy loss, locate areas of moisture intrusion, pinpoint dangerous hot spots in the electrical system, and uncover other problems, such as wood-destroying pest and rodent infestations, as well as flue leaks in the chimney, which can lead to carbon monoxide poisoning.
