    I have a high energy efficiention furnace and I have no cold air returns yet! I do however have the filter installed will it hurt my furnace to run a couple weeks without the cold air return?? As long as its not blocked!

    No, on a high efficiency furnace you will have a separate air intake for combustion air so you should be fine.
