410A

R-410A has replaced R-22 as the preferred refrigerant for use in residential and light commercial air-conditioning and heat pump systems. R-410A was not designed to retrofit existing R-22 systems and should only be used in systems specifically designed for R-410A.

R32 refrigerant, also known as difluoromethane, is an hydrofluorocarbon (HFC) used in heating, ventilation, and air conditioning (HVAC) systems. When compared to other refrigerants, it has higher energy efficiency, lower environmental impact, and other benefits.

R-454B is a blend of refrigerants designed to provide efficient cooling while minimizing environmental impact. It is composed of hydrofluoroolefin (HFO) and hydrofluorocarbon (HFC) compounds, which work together to create a reliable and effective refrigerant.
