    Is the furnace dirty and sucking in a lot of dust? Is there something in the air that could be burning to it? What are you using to clean it with? Don't use sand paper. I just use a small wire brush.

    I never heard of it either. I always supply my own refrig. and use what the manufacture recommends. I would tell him if he wants it charged with that, then he can do it.
