I had my a/c (Trane) checked today, and it needed just under a pound of
Freon. It leaked out over the course of a year (I know this because it was
serviced a year ago). The leak is probably coming from the coils, which I
would rather hold off on replacing for a few months. My question is this:
when Freon leaks from the system, where does it go? Is it possible for it to
get into the air that blows into the house?
