More powerful blower for a Tappan?
Last summer I replaced the outside unit for my air conditioner. It blows cold but it takes some time (runs for hours sometimes) for the inside temperature to come down when it's really hot outside. The guy that replaced the outside unit recommended I replace the unit in the basement too but I simply couldn't afford it. He said the blower is barely big enough for the house, which it why it takes so long to cool sometimes. I've taken the blower out and cleaned the blades but it still doesn't move much air. Would it be possible to replace just the blower with one that moves more air? I don't know where to begin looking and it needs to fit in the same hole the old one came out of. Any suggestions? Details below.
It's pretty old...probably original to the house, circa 1979
