What Is R-22 Refrigerant and Why Does It Matter for Your AC?

If your air conditioner was installed before 2010, it likely uses R-22 refrigerant—often called by its brand name, Freon. R-22 has been phased out in the United States because of its impact on the ozone layer. As of 2020, production and import of R-22 for new equipment are banned. For homeowners in North Texas with older AC units, this creates a critical decision: repair or replace? R-22 refrigerant is still available for servicing existing systems, but supply is limited and costs have risen significantly. A recharge that once cost a few hundred dollars can now run $800–$2,000 or more, depending on the amount needed. Leaks are common in older systems, so you may face repeated, expensive recharges. At some point, replacing the unit with a system that uses R-410A or the newer R-32 refrigerant becomes the more cost-effective choice. How do you know if your system uses R-22? Check the nameplate on your outdoor condenser—it will list the refrigerant type. If you're not sure, an HVAC technician can identify it during a service visit. If you have an R-22 system, we recommend planning for replacement rather than investing in major repairs. New systems are more efficient, use environmentally friendly refrigerants, and come with warranties. Everflow HVAC serves Royse City, Rockwall, and the greater Dallas metro. We can evaluate your current system, explain your options, and help you decide whether repair or replacement makes the most sense for your home and budget.
