Hi, I just bought a show home that is 3 years old the furnace has a new home warranty and there was water in the furnace. It's been determined that construction material was thrown down the vents and plugged the drain spout it was extremely rusty and dirty also took out blower motor it was dry but obvious water damage and rust along with secondary heat exchanger I have pictures. Will the warranty still be good for 20 years and what should I insist that the builder do to correct the situation? He wants to leave the rusted parts and change the control board and rusted electrical connections only.
