When replacing a typical A/C system component, the system must be discharged _____.

When replacing a typical A/C system component, it is crucial that the system is completely discharged. This is important for several reasons. First and foremost, refrigerants used in A/C systems can be harmful to the environment, and handling them improperly can lead to leaks and potential regulations violations. Completely discharging the system ensures that all refrigerant is safely removed before any repairs or replacements are made.

Additionally, working with a fully discharged system minimizes the risk of pressure-related accidents that can occur if the system is not completely evacuated. A full discharge allows technicians to work safely and effectively, ensuring that no residual refrigerant is present that could cause harm during the servicing of the system.

In summary, a complete discharge of the A/C system is essential for safe and environmentally responsible servicing, as well as for ensuring the integrity of the system during repairs.
