If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
They should never be mixed.
Only if you're trying to destroy your AC system. Never mix refrigerants.
The newer Freon (r134) does not mix with the old Freon. The system needs to be flushed, special oil added so that r134 will be compatible with the system gaskets, then a vacuum pulled. Then the Freon can be added.
R134
Absolutely not ... R410 operates at much higher pressures than R22, and mixing would do nothing but contaminate both refrigerants (and possibly mess up your system)
R134 .... IS freon.
r134
Chemical composition and properties, different system pressures, different pressure/teperarature relationships in when they'll change states from liquid to vapor... you never mix refrigerants, period.
When oil is mixed with R410, it can cause the lubricating properties of the oil to deteriorate. This can lead to potential issues with the compressor, as it may not be properly lubricated, reducing its efficiency and potentially causing damage. It is important to use the correct type of oil with R410 to ensure optimal performance and system longevity.
Should be R134
