The ac in my home is the original Carrier unit from the late 70's. My question is that the filter is not inside the home but rather in the unit itself in the garage. i have to take off the two metal doors to get to it and cram in a 14x25x1 filter. that was the filter size and is what was in there when i moved in but it doesn't seem to fit quite right. I have seen another one of my units elsewhere and it had the same set up location and filter size.
My question: Can i put the filter inside the house at the intake like most typical ac's have? would that hurt anything?
