R-410A vs R-22: What’s the Difference?

R-22 is an older refrigerant that was phased out, while R-410A is the newer refrigerant that replaced it in air conditioners built from about 2010 onward. The two are not the same and cannot be swapped in the same system. Each one is made for the system it was designed for.

R-22: the older refrigerant

R-22 was used in most home air conditioners for many years. It belongs to a group of chemicals that can harm the ozone layer. Because of this, the United States stopped making and importing new R-22 on January 1, 2020.

R-22 systems can still be used and serviced. But the refrigerant now comes only from recovered and recycled supply, which makes it harder to find and more costly over time.

R-410A: the replacement

R-410A came in as the main replacement for R-22. It does not harm the ozone layer. It runs at a higher pressure than R-22, so it needs equipment built for it.

R-410A is now going through its own phase-down. New systems built in 2025 and later use lower-impact refrigerants like R-454B and R-32. Still, R-410A remains legal to buy and use for the millions of systems already installed.

Can you put R-410A in an R-22 system?

No. This is one of the most important points to understand. The two refrigerants run at different pressures and use different oils. Mixing them or using the wrong one can damage the system and is not allowed. The refrigerant must match the system.

If you have an older R-22 system that needs frequent repairs, a licensed technician can help you compare the cost of service against replacing the unit with a newer system.

Which one do I need?

You need whatever your system was built to use. Check the label on your unit, or ask your technician. IceCold carries both R-22 and R-410A for legitimate service work.

No matter which type your system uses, the work must be done by an EPA Section 608 certified professional.
