What is the difference between R-22 and R-410A refrigerants?
Refrigerants are what make air conditioning possible. Contained within the coils of an air conditioner
, these liquid agents cool and dehumidify indoor air. For years, the most common refrigerant used in air-conditioning systems was R-22.
In response to growing environmental concerns, production of systems using R-22 refrigerant is being phased out. Lennox has led the way in the manufacture of cooling systems that use chlorine-free R-410A refrigerant. Because R-410A contains no chlorine, it is considered ozone-friendly.
Lennox' highest efficiency cooling systems are designed to use R-410A refrigerant, therefore providing an economic benefit in addition to the environmental benefit. Lennox' R-410A systems are also known for improved reliability, quieter operation, improved dehumidification
and enhanced heat pump
