Topic: Ozone Depletion

Petroleum-derived hydrocarbon refrigerants are approximately 30% more efficient than mandated HFC 134A alternatives and cost significantly less at roughly $9 per can. Critics of current mandates argue that the approved chemicals, such as R12 and HFC 134A, pose severe health risks including the production of phosgene gas or hydrofluoric acid when exposed to heat or sunlight. The discussion suggests that state-mandated conversions create a monopoly for companies like DuPont while increasing maintenance burdens on consumers.
