    Where to buy CO2

    I just started working HVAC and I went through my first tank of CO2 today. Only trouble is, I don't know where to get it filled! I live in the dupage (illinois) area. I'm headed over to willowbrook tomorrow. Anyone know where one buys CO2 refills?

    That's strange they don't carry compressed CO2.

    When I used CO2 20years ago, I'd get it from PG Walker which is now Airgas.

    Here you go. They list bone dry??? Looks like the cylinders they use in labs.
