    What is the "thump-thump--thump---thump----thump" noise that I hear from the indoor unit of my heatpump after it cycles off, does it matter, is it the fan out of balance? It think it started two weeks after it was checked by a professional, or maybe the sound was always there and I'm just noticing it now--jAmEs

    Thump thump thump=call him back, he forgot to remove the mouse from the blower housing. Seriously, have him look at it again and state your concern.
    If everything was always done "by the book"....the book would never change.
