Which action prevents F-Gases from being released into the atmosphere during repairs?

Using recovery equipment is crucial for preventing F-Gases from being released into the atmosphere during repairs because this equipment is specifically designed to capture and store refrigerants safely. When working on systems that contain F-Gases, technicians use recovery equipment to evacuate the refrigerant from the system before any maintenance or repair work begins. This process not only ensures that harmful gases do not escape into the environment but also allows for the safe handling and potential reuse of the refrigerant in compliance with environmental regulations.

In contrast, while maintenance checks can help identify leaks and ensure that systems are functioning properly, they do not inherently prevent gas release during repairs. Air filters serve a different purpose, focusing on improving air quality rather than managing refrigerants. Conducting energy audits can assess system efficiency and usage but does not prevent the physical release of F-Gases during repair activities. Thus, the use of recovery equipment stands out as the most effective practice to safeguard the environment during service work.
