For the last couple of months I have noticed "shimmy" or vibration in the floor around my closet that houses my furnace/air conditioner. The vibration resonates throughout the upstairs bedrooms and even rattles the windows downstairs. Had a/c company that did the install out yesterday to check it out. He told me that the blower wheel could be out of balance and need replacing. Does this seem right for a unit that is less than 2 yrs old? The blower is under warranty but of course I have to pay the labor. It is a Carrier 58STA 5 ton furnace w/ matching 5 ton a/c coil.
Thanks for any input!
