Refrigerant 410a pressure.
R410A. R410A is an HFC blend designed for new R22 applications. It operates at higher pressures than many other refrigerants, and so cannot be used to retrofit R22 systems. Systems designed for R410A can take advantage of its ability to use smaller components, making it a key refrigerant for domestic and light air conditioning equipment.
R-410A refrigerant costs approximately $8 to $12 per pound or about $200 to $300 per 25-pound container. Starting in 2020, the EPA banned the import and purchase of R-22 Freon. If you have an older unit that takes R-22 refrigerant, you can’t simply add R-410A because of the pressure differences between the two products.R22 / R410A.
