R22 split air conditioners were once a popular choice for residential and commercial cooling systems. However, due to environmental concerns and regulatory changes, the production and use of R22 refrigerant have been significantly impacted. Here's what you need to know about the current status of R22 split AC units:

Is R22 Still Produced for Split Air Conditioners?

No, R22 refrigerant is no longer produced for new split air conditioning systems. Here’s why:

• Montreal Protocol: R22 is a hydrochlorofluorocarbon (HCFC) that contributes to ozone depletion. The Montreal Protocol mandated a phase-out of HCFCs.
• EPA Regulations: The U.S. Environmental Protection Agency (EPA) banned the production and import of R22 for new AC systems after 2010.
• Global Phase-Out: Many countries have completely discontinued the use of R22 in new equipment.

Alternatives to R22 in Split AC Systems

If you own an older R22-based split AC, you may need to consider alternatives:

1. R410A: A more environmentally friendly refrigerant used in modern systems.
2. R32: An energy-efficient, low-global-warming-potential (GWP) option.
3. Retrofitting: Some systems can be converted to use alternative refrigerants.

If you're still using an R22 split AC, it's advisable to consult a professional HVAC technician for the best replacement or retrofitting options.
