Refrigerant leakage significantly contributes to global warming due to the nature of many refrigerants, which can be potent greenhouse gases. These substances have high global warming potentials (GWPs), meaning that even small amounts released into the atmosphere can have a substantial impact on climate change. In addition to their environmental effects, refrigerant leaks can also diminish the efficiency of HVACR systems. When the refrigerant levels are low, the systems must work harder to achieve the desired temperature, leading to increased energy consumption and higher operating costs.

The environmental concern arises because refrigerants can trap heat in the atmosphere, exacerbating the greenhouse effect and contributing to rising temperatures. Hence, managing refrigerant leaks is critical not only for enhancing system efficiency but also for minimizing environmental damage.
