22-A Substitutes Refrigerant - Second generation replacement for R407c, R404a and MO99
Product Review (submitted on October 24, 2013):
Worked great!! I can buy r22 but wanted to try this because it cheaper to run. Was suppose to same me 25% on the cast of running on my light bill. I was doubting how good it would work But to my surprise it worked very will in fact my ac unit said it took 5lbs of r22 and I only put in 2lbs of this stuff and got readings of 65 to 75 on low side and around 250lb on my hi side and my ducks was putting out 53 deg. air. As the duck people would say Happy Happy Happy!!
