    If the Amana is nominally rated for 18 with a VS motor; and if we assume a loss of 1 point without the VS; and if we assume a loss of another point to lack of airflow due to improperly sized ducts, a smallish lineset or whatever (common problems); and if we assume a delivered SEER of 7 from the old system; then perhaps you'll save $350 a year.
    Too. Much. Bluster.

    Good point. Your math looks more than reasonable. My current compressor is over 15 years old, it has to go sooner or later. Thanks for the links, very informative.
