I wasn't sure if you got the estimate copy. See below. I have hot water base board heating separate from air conditioner. This is replacement of the Attic unit and the outside unit. They are using my existing thermostat and air ducts. I cannot find what the costs for the carrier units they are to replace. Please see specifics in the estimate.
