Infrared (thermal imaging) in home inspection uses specialized cameras to detect heat patterns, revealing hidden issues like water leaks, insulation problems, and electrical faults. These cameras capture infrared radiation emitted by objects, converting it into a visual image showing temperature differences, which can highlight areas of concern that are not visible to the naked eye.

Here's how it works:

• Detecting Moisture:

Water leaks, even small ones, can cause temperature variations. Infrared cameras can detect these subtle changes, revealing areas where moisture is present. 

• Identifying Insulation Problems:

Insulation gaps, improper installation, or missing insulation can lead to heat loss or gain. Infrared imaging can pinpoint these areas, allowing for targeted repairs and improved energy efficiency.

• Electrical System Issues:

Overloaded circuits or faulty wiring can generate excess heat, which infrared cameras can detect, potentially preventing electrical fires. 

• HVAC Problems:

Infrared can help identify leaks in ductwork, inefficient heating/cooling systems, and other issues related to the heating, ventilation, and air conditioning system. 

• Other Applications:

Infrared cameras can also be used to detect pest infestations, air leaks, and other problems that can affect a home's structural integrity and energy efficiency. 

In essence, infrared imaging provides a non-destructive way to "see" beyond the surface and identify potential problems that might otherwise be missed during a standard home inspection.
