After installing a new A/C how would you test it?

• A. Check the refrigerant level
• B. Turn on the breaker and check voltage
• C. Inspect the ductwork
• D. Run a diagnostic test

Answer: (B)

Turning on the breaker and checking voltage is a crucial step after installing a new air conditioning (A/C) unit because it ensures that the system is receiving the proper electrical supply. Voltage testing confirms that the unit is connected to the correct voltage source and that there are no issues with the electrical supply that could compromise the performance of the A/C system. Ensuring that the unit has the correct voltage supply is essential for the safe and effective operation of the air conditioning unit.

Checking the refrigerant level, while important for the overall efficiency and performance of the A/C system, is typically done after confirming that the electrical system is functional. Inspecting the ductwork is vital for ensuring that air can flow freely and that the system will operate efficiently but is not a direct test of the A/C unit’s electrical operation. Running a diagnostic test may help identify issues with the A/C’s internal components but also assumes that the A/C has been powered and is receiving proper voltage first. Thus, testing the voltage is an essential initial step in the process of ensuring a new A/C system is ready for operation.
