Which tool is primarily used for visual inspections of HVAC systems?

Hygrometer
Borescope
Manometer
Microscope

The correct answer is: Borescope

The primary tool used for visual inspections of HVAC systems is the borescope. This instrument enables technicians to visually inspect areas that are difficult to access, such as ductwork, vents, and other components of the HVAC system. A borescope features a thin, flexible tube with a camera at one end, allowing for inspection without dismantling parts of the system. This capability is crucial for identifying blockages, damage, or mold growth inside ducts. In contrast, a hygrometer measures humidity levels and is useful for understanding the moisture content in the air, but it does not provide a visual inspection capability. A manometer gauges pressure within the system, which is crucial for performance measurement but not for visual assessments. A microscope is designed for magnifying small objects and is typically used in laboratory settings for detailed analysis of samples, rather than for inspecting HVAC systems. Thus, the borescope stands out as the optimal tool for visual inspections in this context.
