Infrared Thermography is a technology that makes infrared light visible to the human eye. It allows to see hidden defects that others inspectors would not catch, like:
You notice on the right side a longer darker (blue) spot. This is a serious water leak from a washing machine.
Moisture (dark spot) noticed above a bed that is not visible to the naked eye.
Moisture (dark spot) noticed in the corner of the ceiling.
A breaker in the electrical service panel is hotter than 140°F this most likely indicates an overloaded breaker and is a fire hazard.
Not well insulated duct connection. Cold air (darker spot) is leaking into hot attic space. This might cause condensation.
The yellow area indicates hot air entering from outside. Lack of insulation
Bright area (yellow, orange) indicates hot air entering from outside. Lack of insulation.
Electrical plug is much hotter than the ambient temperature. This is a fire hazard.
Moisture problem (dark/purple spot) around the toilet.
