death by freon?

[tora]

would death by inhaling freon be painful? my AC has a freon leak and I have to have it refilled every couple months. no idea where it's leaking to, but if I find a way to get it into my house would it be quick and painless like CO or would it take a while and be painful?

As per Google, How well a person does depends on the severity of the poisoning and how quickly medical help was received. Severe lung damage may occur. Survival past 72 hours usually means the person will have a complete recovery. Sniffing Freon is extremely dangerous and can lead to long-term brain damage and sudden death.

So, I guess it would be effective but I'm not sure about this method, if there is anything else available for you, you should look more into those methods. I'm not sure about this one.
