Inquiry (采购产品): gas furnace heat exchangers I am with PACE community action agency, we weatherize homes for low income families and also do health and safety which include furnace services. I am in need of finding out info to see if it is feasable to replace an heat exchanger or just replace a furnace in residential applications.It is my hope that we can cut cost by replacing heat exchangers instead of the complete furnaces.
