Chapter 1, Problem 1RQ

True or False: A heating and air-conditioning service technician can usually troubleshoot heating and air-conditioning systems without the voltage being supplied to the equipment.

Expert Solution & Answer

To determine

Whether the given statement is true or false.

Explanation of Solution

Electrical power supply is important for troubleshooting the electrical equipment such as electric motors, electric heater, and any other electrical appliances. Without electrical power supply, the problems found in the electrical appliances cannot be identified. Thus, a heating and air-conditioning service technician must need electrical power (voltage) supply to troubleshoot a heating and air-conditioning system. The identified faults are repaired at the power off condition.

Thus, the given statement “A heating and air-conditioning service technician can usually troubleshoot heating and air-conditioning systems without the voltage being supplied to the equipment” is false.
