Not unless you like the idea of destroying your AC system.
no.
No
No
It is not recommended.
No , they operate at different pressures and are not compatible.
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)
NO! You NEVER mix refrigerants.
You end up destroying your AC system.
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.
Your AC won't work any better than it did before. Two very different refrigerants, which will not blend, with different superheat points and system pressures. Not to mention that R22 won't carry PAG oil through the system as effectively as 134a, meaning you could end up starving your compressor of lubricating oil, thus burning it out.
No
Probably uses R-12 refrigerant but if you are having a problem with your ac you should convert to the new R-134a refrigerant . Look for a decal under the hood or on the compressor to make sure. The two refrigerants do not mix.
