Miriam,

Yes.... an HVAC contractor.

Price? Just not enough information to be able to guess. How many levels, How many units, is the attic easily accessible, are your units already appropriately sized or are they under or over-sized (tonned), what about return air??

There are just too many varriables to even put a W.A.G. (wild arse guess)to the cost.
