    The problem with an amonia system is that breathing anhydrous ammonia will in all likelyhood, ummm put you in the hospital or kill you. Nasty stuff if you aren't carefull with it. I wouldn't want an ammonia system in a residential situation.

    Don't laugh to hard, Europe is already transitioning to HFO refrigerants, as well as systems that use a transcritical CO2 cycle. There is even transcritical CO2 equipment in use in the US in some applications, and you should start seeing HFO refrigerant using refrigeration equipment in the US soon.

    At the AHR expo, there was at least one Asian manufacturer showing a trans critical CO2 heat pump SPLIT SYSTEM!
    If more government is the answer, then it's a really stupid question.

    Sure all that "trascritical HFO" is slowly coming this way but 410a is not going anywhere any time soon.

    Hey, that's great. Just something else for the EPA to regulate and tax. Have a leak? $50 fine, have to recharge, $500 fine, don't keep records of what you use, $50,000 fine. CO2 is a greenhouse gas now, isn't it? Congress aught to have a field day with it.

    I remember techs saying the same thing when we went from R12 to R22 for A/Cs.

    If your campus has more cash than they know what to do with, go with new 410A units.

    Worry later about tree huggers getting 410A phased out.
