In a car, you have the advantage of getting nice strong blast of air right on your face. Not so in a home (unless you spend your time with your face against a supply register.) I wont go into the differences between auto and residential heating and cooling for the simple fact that I would have to charge much more than $1.50 per minute to do so,,lol.
PS. I am a slow typer, so I believe you owe me about $4.50 for this info,,,
