Does Walmart put freon in cars?

No, Walmart does not put Freon in cars. Freon is a brand name for a type of refrigerant, commonly used in air conditioning systems, but most automotive air conditioning systems now use more environmentally friendly refrigerants like R-134a or R-1234yf. Walmart does offer automotive services, including air conditioning recharge, but they use the appropriate refrigerant for the vehicle in question. It's best to consult with a technician for specific services related to your car’s air conditioning system.
