Either you're a troll or a complete idiot.

Apparently you and the previous poster don't
realize there is a big difference between using
ammonia or natural gas in a system DESIGNED
for it and putting it into your home AC system
which was not. Your question is about putting everything
from auto R134 to ammonia into your present
home AC. And apparently ammonia isn't practical
for such systems today compared to the other
refrigerants or HVAC manufacturers would be using it.

So, again, either you're an idiot or a troll.
