What you'll experience

1. 1

   Dead Capacitor

   The scenario begins with the narrator explaining what a failed capacitor is, how it affects system performance, and the telltale signs — clicking sounds, failure to start, or components struggling to run. The participant must first disconnect the unit from power and verify that all stored electrical energy has been safely discharged. Failing to do so can result in electrocution within the simulation, underscoring the importance of electrical safety. Once the system is safe to handle, the user identifies the correct replacement capacitor and installs it properly.

2. 2

   Low Refrigerant

   The user disconnects power to the unit, then attaches a pressure gauge to assess refrigerant levels, discovering that the system is undercharged. To investigate further, the participant removes an access panel and uses an ultrasonic leak detector to scan the refrigerant lines. When the tool signals a leak, the user retrieves a brazing torch to repair the compromised section. After sealing the leak, the system must be flushed and recharged with refrigerant to restore proper operation.

3. 3

   Clogged Drain Line

   The user operates a wet/dry vacuum to clear the blockage while the narrator explains proper technique and tool handling. After clearing the obstruction, the participant flushes the drain line with a vinegar solution to confirm that water flows freely through the system. They then remove a panel to inspect the drain pan and test drainage by adding water. Once the system drains correctly, the repair is complete.

4. 4

   Dirty Air Filter

   The participant replaces a dirty furnace air filter. The narrator explains how to identify airflow issues and why checking static pressure is a critical diagnostic step. After recording the initial static pressure reading, the user replaces the filter and takes a second measurement. The improved reading demonstrates the impact of proper filtration on system performance.
