Why the Need for Refrigerant Conversion? 24 Hour Emergency Heating Service Emergency Ac Repair Near Me 24 7 Air Conditioning Service Local Air Conditioning Service

The primary driver behind refrigerant conversion is the need to protect the Earth’s ozone layer and reduce the impact of greenhouse gases on the climate. Older refrigerants, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), were found to have a significant ozone depletion potential (ODP) and global warming potential (GWP).

• Ozone Depletion: CFCs and HCFCs contain chlorine atoms that, when released into the atmosphere, can break down ozone molecules in the stratosphere. The ozone layer is crucial for shielding the Earth from harmful ultraviolet (UV) radiation from the sun.
• Global Warming: Refrigerants with high GWP contribute to the greenhouse effect, trapping heat in the atmosphere and contributing to climate change.

International agreements, such as the Montreal Protocol, have phased out the production and use of CFCs and HCFCs. As a result, newer refrigerants with lower ODP and GWP have been developed and are now being used in HVAC systems. 24 Hvac Service Near Me Ac Emergency Repair Near Me 24 Hour Hvac Ac Unit Replacement Near Me
