i kind of want to do everything myself. would I just turn on the air and spray it into the blower? or would I have to actually remove components of the a/c system? also I was just going to use ozium to do this,.. is there anywhere I can buy that BG stuff myself?

 

just run heat to dry evething out, then use ozium method. in summer run heater to dry things out.

 

no, you cant buy the bg stuff anywhere, and the ozium will work for about a day.
