Which tool is typically used for inspecting electrical components in HVAC units?

• A. Screwdriver
• B. Multimeter
• C. Wrench
• D. Pliers

Answer: (B)

The multimeter is a crucial tool for inspecting electrical components in HVAC units because it allows technicians to measure voltage, current, and resistance. By using a multimeter, you can diagnose electrical issues, check the integrity of connections, and determine whether components such as capacitors, relays, and sensors are functioning correctly. This ability to assess electrical performance is essential in ensuring the HVAC system operates efficiently and safely. The versatility of a multimeter makes it indispensable in various scenarios, such as troubleshooting circuit issues or verifying that power is reaching different parts of the system. In contrast, a screwdriver is primarily used for fastening or removing screws; a wrench is designed for turning nuts and bolts; and pliers are utilized for gripping and cutting. While these tools are important in HVAC work for mechanical tasks, they do not provide the electrical diagnostic capabilities that a multimeter does.
