    Sorry, what I meant to say is a lot of our larger accounts have decided on their own what refrigerant they want to use.

    If you are going to change out refrigerant go with R407C it is a real refrigerant that comes in new equipment that will be around for awhile not like the 8 million other refrigerants. If you don't want to change the oil on a semi hermetic you are just lazy.
