Environmental regulations, such as the Montreal Protocol and the European Union’s F-Gas Regulation, have led to the phase-out of ozone-depleting substances and the transition to more environmentally friendly refrigerants. This has resulted in increased demand for alternative refrigerants, leading to price increases. Additionally, regulations may impose restrictions on the use of certain refrigerants, further affecting pricing. Staying up-to-date with regulatory developments is crucial for HVAC professionals and system owners to anticipate and adapt to changes in refrigerant pricing.
