A standard visual inspection identifies problems that are visible - damaged wiring, worn outlets, physical defects in the panel. Thermal imaging finds problems that are invisible to the eye but generate heat inside the wall, ceiling, or panel.
Here is what thermal imaging detects during an electrical inspection:
🌡Overloaded circuits - a circuit carrying more current than its wiring is rated for shows as a hot spot in the thermal image. The wire may look fine visually but is heating up behind the wall.
⚡Loose connections - a loose connection at a breaker, outlet, or junction box creates resistance that generates heat. This heat shows up in thermal imaging as a bright spot around the connection point.
🔲Failing breakers - a breaker that is about to fail often runs hotter than the breakers around it in the panel. Thermal imaging identifies these before they fail.
🔥Arcing - arc faults inside a wall show as heat in the thermal image. These are exactly the type of fault that causes fires behind finished walls without triggering a standard circuit breaker.
We use thermal imaging cameras on inspection visits for Arlington TX homes where the homeowner requests it or where the initial visual inspection suggests hidden issues. Thermal imaging adds time to the inspection and is offered as an add-on to our standard inspection service.
