I am building a new house and my contract calls out a hot roof, two zone heat and the placement of the heating system in the basement. I am not getting a Hot Roof, only getting single zone heat and the heating system was placed into the attic. I tried to work it out with the contractor and he would rather refund our money and sell the house to another party as he believes he can get more for the house. We do not wish to walk away. What are our options?
