22-A Substitutes Refrigerant - Second generation replacement for R407c, R404a and MO99
Product Review (submitted on July 25, 2013):
I moved a friends mobile home, the A/C people said it would cost between $500 and $750 dollars to reinstall central A/C. They also said it would take them 5 weeks before they could come out due to work load. I order this product the same day ($141), it arrived 5 days later. I used my R12/R134a gauges to install the R22a. Extremely fast charging, very little used. It is now 2 weeks later and A/C is still cold and the owner of the house says that the unit runs less often. Very good value for the money. I still have enough to recharge 3 or 4 units the same size.
