Air conditioners use two different types of refrigerant. Older models use R-22 and newer models use R-410A. R-22 refrigerant is being phased out due to a revised Clean Air Act that requires all new air conditioning systems to use substances that do not deplete the ozone layer. R-22 is still available but no manufacturer can produce this type of unit and all R-22 units must be eliminated by 2030.
They type of oil used in air conditioning compressors is also different. The R-22 compressor uses a mineral oil, while the R-410A compressor uses a synthetic oil. These oils cannot be mixed. If you were to put the R-410A refrigerant into an R-22 compressor, the motor would overload and burn out causing the system to shut down. The R-410A also has more pressure pushing through the tubes of the unit than an R-22 compressor. This could cause the compressor tubes to burst.
There is also a significant difference in cost. The R-22 refrigerant is substantially more than the R-410A. With that being said, if you have an older air conditioning unit that requires R-22 and is low on refrigerant, you would most likely be better off replacing the unit than having to add several pounds of R-22.

Barry has just left after giving us a walk through of our new systems which are vastly superior to what was replaced. Jake, Adam, Will, Barry and Brian were all skilled, diligent, professional and courteous in every aspect. Clearly, we chose wisely when we hired you.

Thank you for the follow-up with hot water heater turn-on and excellent job on air conditioning grounding. The two men who did the electrical grounding work on the air conditioning were exceptional.
