What should technicians do if they discover a leak in an MVAC system?

Ignore it
Repair or replace the leaking component
Report it and continue working
Evacuate the refrigerant and seal it

The correct answer is: Repair or replace the leaking component

When technicians discover a leak in an MVAC system, the most responsible and effective course of action is to repair or replace the leaking component. Addressing leaks promptly is essential for several reasons. First, leaks can lead to the loss of refrigerant, which not only diminishes the system's efficiency but can also result in increased greenhouse gas emissions. This is particularly relevant under regulations that aim to minimize the environmental impact of refrigerants. Additionally, allowing a leak to persist can result in more extensive damage to the HVAC system, leading to higher repair costs and reduced system life. By repairing or replacing the leaking component, technicians ensure that the system operates correctly and efficiently, adhering to environmental safety standards and maintaining peak operational performance. This proactive approach contributes to the longevity of the equipment and aligns with best practices within the industry.
