Freon does not have any odor. If you are smelling something from your car air conditioner, it is probably leaking some anti-freeze from the heater core of your car.
Freon technically has no smell but there are substitute's used that do the same thing as freon that are different chemicals that do have smells but usually you can only tell when there is a leak.
Freon, like all gases, is colorless and odorless. However, should it become overheated or near a flame it can turn into phosgene gas or "mustard gas" which has an acidic smell and can burn the lungs severely.
Not a thing. Freon is oderless and completely un detectable.It is used in air conditioners in homee and in cars. most retail shops don't care it. but you can find it in specialtiy shops if it is not illegal in your state.
