Can you use a R-134a machine for 1234yf?

No. R134a systems were not designed to operate using a flammable refrigerant. R134a systems should not be converted to use R1234yf as these systems are unable to be converted to a level that satisfies the requirements of international standards (SAE J639 and SAE J2842) set for systems that use R1234yf.

Converting R1234YF to R134A... was it a mistake?



What happens if you put the wrong refrigerant in your AC unit?

The AC System May Overheat

Like mentioned above, different refrigerants have different sitting temperatures. Like oil and water different refrigerants do not mix, so you have different temperatures cycling through your system. This can lead your AC system to overheat and a burnt motor, a costly repair.

Is it illegal to mix refrigerant?

It is Against the Law – As the EPA has phased out the use of R-22 refrigerants, it is illegal for contractors to mix refrigerants. This is because when mixed, the refrigerant is no longer reusable and must be incinerated. While it is unlikely you will be prosecuted for this, it is just not a great idea.

What happens if you accidentally put 410A in a R22 system?

Since R410A refrigerant is charged under higher pressure, charging an R22 system with it will increase the force within the lines. The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur. Mixing refrigerants is not an option either.
