Hi All Friends,

I know enough about AC systems to occasionally get in trouble.
And I've read and reread the thread about the change to HC-22a, a while back on the forum.
The rooftop Duotherm unit starts and runs good, cools about a 5 to 6 maybe a 7 on a scale of 10 (it's cool not cold outlet air ). I haven't found Doracool HC-22a in small cans size (30 lbs. equivalent size only).
My question.
Since Duracool HC-12a (I have on hand) works with any oil and I'd be replacing the freon completely,
can HC-12a work (the same or better) in a R22 system?
Thanks you, for the wisdom and advice.
