Freon, DuPont R22 (Dichlorodifluoromethane) is described in the MSDS as having a "slight ethereal" odor. I cannot say that I have noticed any odor from any systems that I have accidentally dumped. Then, again, I don't stick around to sniff it and I have never dumped a system in an enclosed space.

If you have ever smelled chloroform, it is also described as having an "ethereal" odor. It is best not to sniff that either.

There is many different types of Freon. If the freon that you are trying to use is R-22 then you have to have a EPA certification to handle that freon. This freon is considered ozone depleteing. Now there is freon out there that is not ozone depleting like the freon in cars made after 1993. That is called R-134a which is sold everywhere even in Wal-Mart.
