What is the typical storage life of modern refrigerants?

5 to 10 years
10 to 20 years
20 to 30 years
Modern refrigerants have an indefinite storage life

The correct answer is: Modern refrigerants have an indefinite storage life

Modern refrigerants are designed to have a very long shelf life, and many are stable and effective for an indefinite period when stored correctly. This is due to the chemical properties of these refrigerants, which resist degradation over time. When kept away from factors such as high heat, moisture, and contaminants, modern refrigerants can maintain their effectiveness without losing their properties for many years. This stability is crucial for technicians who rely on refrigerants for repairs or new installations, as it allows them to stock up on refrigerants without concerns about expiration or reduced performance. In contrast, other choices imply limitations on storage life, which do not reflect the durability of modern refrigerants when they are properly handled and stored. Thus, stating that modern refrigerants have an indefinite storage life accurately reflects their robustness in typical conditions found in service environments.
