Online and some Houston shops are selling R-22 refrigerant for $25 - $30 per lb. The local A/C companies I contacted were charging over $200 per lb. Information I've read said we actually have a surplus of old R-22 stock in the U.S. (it's now illegal to produce or import it) because the A/C industry was so effective at moving off of the refrigerant. Any suggestions on some local businesses that will sell R-22 for a more reasonable price?
