Ray -
Condensor, evaporator - I can never keep them straight. I thought
the piece outside was the compressor? Whatever it is, the big noisy
thing with the fan that gets warm when the a/c is running is still
outside. The furnace, with the blower motor is inside.
The house, along with the heat and a/c are 8 years old. I actually
have no registers in the basement. The only one that was down there I
"covered up" when I finished the basement as the register would have
been in the ceiling of the linen closet. With no registers in the
baement, the cold air is getting in the basement my "settling" down
there from the upper floors. In the winter time is not that bad down
there. I assume that's because I'm pumping hot air upstairs not cold so
there is nothing to settle into the basement.
