Can i mix r22 and r22a

And finally, I was informed Ra will make any rubber seals such as in Schrader valves smaller, again resulting in more leaks. Was that it? Does it just come down to more leaks and recovery problems?

Understand this: The mineral oil in a compressor has a vapor pressure. Yet, the company spokesperson assured me that mixing Ra and R22 combines their pressures and reaches a lower median. Is that true? Not according to the gas laws I used to teach.

Rather, the books I taught from say that each refrigerant reaches its own vapor pressure. It will just flood back to reduce the compressor life and will greatly reduce the system capacity. Do I have an answer? No, but I suspect that mixing the two refrigerants is a terrible idea. Meanwhile, hundreds, thousands and soon millions of air conditioners may be contaminated in this way.

More leaks are in the coils, then in line sets. You just gave another good reason not to use that HAVC company. Mixing refrigerants is a violation of EPA regs. Just because they are blowing out the same temps, doesn't mean they should be.

Air flow, effects coil temp difference. And since it isn't, its putting more load on teh other unit. Yes, it must be recovered, vavuumed, and recharged with new R22 only. I wouldn't use that company again, if mixing gasses is their normal answer to a leaking system.

DIY - not here. Don't post it again. This thread is closed.
